1.0 Introduction

 

RPS (previously operating as Naturat Solutions) has been commissioned by Matrix Projects (Qld) Pty Lid to
prepare an Ecological Restoration Plan (ERP) for the approved redevelop the Peregian Beach Caravan Park
located at 215-219 David Low Way, Peregian Beach. The principal author of this report (Dr Watson) was.
involved in the initial ecological assessments for the site and provided advice pertaining to development
opportunities and environmental management. The ERP has been prepared in response to the
Devetopment Approval Conditions for a Reconfiguration of a Lot (ROL) application, issued by Sunshine
Regional Council (SRC). The ERP has been prepared in accordance with the requirements of the Noosa
Planning Scheme Policy 18 — Ecological Assessment Guidelines.

 

The scope of the ERP is in accordance with Condition 53 - 56 of the Development Approval issued by SRC
on the 8th October, 2009. The ERP will focus on the western portion of the site, which will be dedicated to
Council as Parkland. Specifically, the scope of the plan includes:

. Outlining the rehabilitation concept with the generat objectives, strategy and target community;

. Prescribing the rehabilitation management measures to be implemented in order to achieve / execute
the objectives, strategy and target community;

. Providing a rehabilitation schedule with the schedule for maintenance and monitoring works; and

" Outlining the rehabilitation and weed removal methods to be utilised to implement the rehabilitation
management measures.

{3 Approv

 

The approved development involves the upgrading the current tourist accommodation facilities of the
Peregian Beach Caravan Park located at 215-219 David Low Way, Peregian Beach, Queensland. This will
include the construction of commercial (restauranvretail/offices) and accommodation (units and cabin)
buildings as well as associated infrastructure (recreational facilities), which will replace the existing camping
and caravan grounds.

The proposed development also incorporates an approximate 20m service area comprising 4m wide
landscaped buffer and a six metre fire access trail. A 6m wide stormwater treatment area and a 3m wide
gabion wall diffuser is also included to ensure that stormwater runoff from the development is properly
managed (Figure 1.1).

The western portion of the site, which currently comprises a vegetation buffer and remnant wet heath habitat
adjacent to Noosa National Park, was retained within the development layout as a 35-80m conservation area
/ parkland. The recent ROL approval enables the dedication of this area to the Crown (with Council as.
Trustee) for Environmental Purposes (i.e. Lot 3; Refer to Figure 1.1).

 

1006t1_PR20517_FL_Rehab.doc Page |

The dedicated parkland is situated within the westem portion of the site. The parkland is an extension of the
Noosa National Park, which borders the northem, western and southern portion of the parkland. The
Peregian Caravan Park bounds the eastern portion of the parkland (Figure 1.2).

The terrain of the parkland can generally be described as a level plain with an extremely low relief of <9m
and a level to very gently inclined slope of <2%. Surface water flows westwards from the Caravan Park and
the parkland, towards the Noosa Nalional Park.

The parkland js largely undisturbed and comprises remnant wet heath vegetation, which is currently mapped
as containing Regional Ecosystems (RE) 12.2.7 / 12.2,12 / 12.2.15. Few exotic species were apparent in
this area. The Noosa National Park including the parkland forms part of a Gilgai formation (i.e. hummocky
micro-relief of soils produced by expansion and contraction caused by changes in moisture) of the wel heath.
This vegetation provides substantial habitat values for various fauna and flora species,

The parkland abuts a strip of highly disturbed vegetation, which occurs within the allotment associated with
the caravan park (new Lot 2, Figure 1.2). This vegetation comprises a dense mixture of native and exolic
vegetation. The abundance of exotic weed species in this area is indicative of historical nutrient levels In
storm water run-off. The service area for the Caravan Park redevelopment (i.e. fire trail, stormwater and
landscaping) is to be situated within this disturbed vegetation, which will be removed as part of construction
works.

2.0 Rehabilitation Concept

 

Once rehabilitation is completed, the parkland is to be dedicated as conservation for the purpose of providing
fauna habitat and an ecological buffer to the Noosa National Park. The aim is therefore to improve the
ecological condition of the parkland by removal of the primary threatening processes (i.e. weed invasion).

Although rehabilitation will focus on the eastern weed infested area, generally rehabilitation efforts will aim
to:

. Minimise further ecological impacts;
. Restore the existing remnant vegetation community;
= Resiore native fauna habitat;

. Restore and retain ecological functions of the parkland and surrounding national park;
» Enhance the buffering capacity of the parkland; and
» Restore the parkland to a resilient self sustaining ecosystem.

2,2 Target Cor

 

Rehabilitation within the parkland will aim to restore the existing remnant vegetation community. The
remnant community consists of a mixed RE polygon containing RE12,2.7 / RE12.2.12 /RE12.2.15. All three
REs will form the target community for rehabilitation efforts.

The suitability of each community to different areas of the site is dependent on the degree of waterlogging
within these areas. RE 12.2.7 is best suited to slightly drier portions that are seasonally waterlogged, RE
12.2.12 is suited towards areas where the water table is higher and soils often become seasonally
waterlogged. RE 12.2.15 is best suited to areas of the site that are frequently waterlogged.

Re-instatement of RE 12.2.7 will be best suited along the interface of the parkland and the Caravan Pavk.
Conditions gradually become more heavily saturated to the west of the sile thus a steady transilion to REs
12,.2.15 and 12.2.12 will be favoured. As the majority of the parkland area is relatively undisturbed
revegetation efforts will focus on species typical of RE 12.2.7 which dominates along the edge of the
parkland and Caravan Park, The prevailing conditions on the site will help encourage the development of
appropriate vegetation community structure and composition across the parkland. Descriptions of each RE
are provided in Table

2.3 Strategy

In order to achieve Ihe above objectives and targel community, a strategy has been devised to guide and co-
ordinate rehabilitation efforts in a logical fashion. The strategy is divided into rehabilitation treatments and
zones. Rehabilitation eatments are a set or combination of actions such as revegetation, weed removal
etc. Rehabilitation zones dictate the extent and details of each treatment type. The on-ground
implementation of the strategy is described in Section 4.0.

2.3.1 Rehabilitation Zones

Various rehabilitation treatments are proposed as part of the rehabilitation strategy and as such, the site has
been divided into rehabilitation zones as shown in Figure 2.1. The strategic approach is modified to reflect
the current and future condition and requirements of each zone. Rehabilitation zone 1 encompasses the
entire caravan park area and will undergo extensive weed removal treatment and supplementary planting in
accordance with the approved Landscape Plan. Rehabilitation zone 2 occurs along the interface of the
parkland and caravan park (i.e. gabion wall) and Rehabilitation zone 3 encompasses the remaining portion
of the parkland. Both zones will undergo weed removal where necessary, and infill planting (i.e. revegetation
works).

2.3.2 Rehabilitation Treatments

The parkland is currently in relatively good condition with limited weed incursion present and limited
disturbance to the canopy cover. The vegetation within the parkland is considered remnant and of high
ecological value. However, the ecological condition of the parkland Is currently threatened by the highly
degraded community direclly to the east of the parkland within the redevelopment area of the Peregian
Beach Caravan Park. In particular, the extensive weed incursion within the caravan park site poses a risk of
spreading and degrading the parkland.

Therefore the strategic approach for rehabilitation will primarily entail weed removal within the caravan park
development site. Dominant and highly invasive weed species occurring within the development site will be
targeted; however weed removal treatments will aim to remove all exotic species occurring in the area.
Where possible, all mature trees within the landscape and stormwater bulfers will be retained.

The parkland itself will undergo little rehabilitation work. However, some weed removal will be employed
along the edges of the parkland and anywhere within the parkland that has undergone disturbance. This is
to create a natural environment that encourages regeneration within and adjacent to the existing remnant
heath community.

Ensuring minimal disturbance throughout the rehabilitation process is imperative to ensure favourable
conditions are maintained for regeneration. The construction of the gabion wall and weed removal may
cause some disturbance along the boundary and open areas within the parkland that may be susceptible to
further weed invasion. Natural regeneration within the parkland will therefore be assisted by undertaking
some infill planting (i.e. revegetation work). Revegetation works will therefore focus on the planting of
canopy and understorey trees where Jarge ‘gaps’ are evident.

Prior to construction activities (including vegetation clearing) commencing on site a wire fauna fence shail be

erected around the perimeter of the parkland area to be restored. This fence will have signs attached
testricting entry to authorised persons only.

  

jon ©

Erosion and sediment control fencing is to be erected in accordance with the approved stormwater
management plan (Simmonds & Bristow, 2009). This is to prevent erosion within rehabilitation areas
disturbed by construction activities.

3.3 Weed Management and Site Preparation
3.3.) Weed Removal Strategy

Mechanical control is ihe preferred technique to remove weeds within and adjacent to the parkland area.
Mechanical control methods include:

» Manual removal by hand or grubbing by using loppers, hatchets or small saws to remove the weed
including the roots;

. Lopping where the weed is removed by an axe or chainsaw;

a Mowing or brush-cutting lo remove the seed heads of the weed species;

* Ringbarking, which involves removing the sapwood around the enlire girth of the {runk near the base
of the exotic plant; and

. Mechanically scraping weed material, using an excavator, into the caravan park site for removal off-
site.

Table 3.1 outlines suitable trealment / control methods for the dominant weed species identified by RPS on
the site. Other weed species not listed in Table 3.1 should be mechanically treated where possible and in
accordance with the Queensland Primary Industry and Fisherles (QPI&F) fact sheets are provided in
Appendix C. A full list of weed species occurring on the site is provided in Appendix D.

If chemical treatment is required to control regrowth and secondary invasions, the selected chemical should
also be frog-friendly (e.g., Roundup® BioactiveTM Herbicide or Weedmaster® Herbicide). Particular care
must be taken not to contaminate the area through chemical spills. Herbicide is to be directly applied to
weeds and broad scale spraying is not permitted. Use of chemicals only by qualified personnel/contractors.

3.3.2

Weed Disposal

Waste vegetation should be placed in a disposable bag, sealed and disposed of off site or placed in a
Council approved facility. Burning of cleared exotic vegetation is not a permitted disposal technique.

 

Revegetation works will be required to infill gaps that may occur along the boundary of the parkland as a
result of historical disturbance and weed removal. Revegetation efforts should commence immediately
following the completion of the gabion wall.

A variety of species have been recommended as part of the treatment type and is detailed in Appendix A.
Recommended species selection for revegetation has been made according to:

. Naturally occurring vegetation within the parkland area;

® The individual growth form of species;

. Ecological function of species;

. The structural role species perform in the natural vegelation community; and

" The objective of the ERP (e.g. provision of fauna habitat, restore RE community, movement
opportunities etc).

It is acknowledged that the area for planting is relatively small, however the species list is provided as a
guide for rehabilitation and landscape opportunities. It is proposed that predominately canopy species
(e.g. Melaleuca quinquenervia) will be planted with shrubs and ground cover used to ensure potential “future
weed invasion” is kept to a minimum. Local growing and climatic conditions at the time of rehabilitalion may
dictate some modifications to the rehabilitation strategy as directed by a restoration ecologist.

bed
or

 

Species used for revegetation should be setected from Appendix A. Where possible, local seeds should be
collected and germinated for revegetation works to maintain local provenance and to increase the short and
long term viability of seedlings planted in the area. Were seeds are not available, local tube stock should be
used. All efforts should be taken to retain and support regenerating native species.

3.5.1 Planting Stock
All planting stock will need to be:

" Preferably local provenance;

. Healthy and displaying signs of active growth. Plants should be rejected if they display ‘yellowing’, leaf
or stem damage or disease, root curling or restriction related to being ‘pot bound’, or have weed
species in the container;

= Minimum of 20cm tall for tube-stock (larger for potted stock); and

. Sun-hardened.

3.5.2 Planting

The densities proposed to be planted will be determined following detailed ground-truthing for each area that
requires planting and in consultation with the Restoration Ecologist. Also, planting stock is to be randomly
planted (i.e. not in rows) which will also affect the densities to be planted.

Generally when planting, the planting holes should be at least twice the widih and half as deep again as the
pot size. In the case of tube-stock, plants should be placed in a hole deeper than the pot, with the root ball
just below the soil surface afler planting. Immediately before planting, each hole will be filled with water
which is then allowed to drain away. Water-holding crystals will be added to each hole and mixed with the
backfill soil to ensure that roots are not in direct contact wilh any concentrated fertiliser. Plants will be
tapped from their container and any pot-bound or circular roots loosened. The plant will be placed in the
centre of the hole, filled in with loose crumbly soil, and then firmed in will with the hands to create a shallow
watering depression. Firming in the plant is very important for settling the roots in and for minimising
erosion.

3.5.3 Plant Guards

Plant guards shall be installed around seedlings to prevent predation by herbivores such as Hares and
Macropods and provide protaction from Competition during the establishment phase.

(@@611_PR20517_FL_Rehab.doc Page tI

Page 16

 

 

3.5.4 Mulching

Site generated mulch from chipped trees and other vegetation and / or other non-weed bearing mulch should
be used throughout the rehabilitation areas including around all planted stock. Each plant should be mulched
to a radius of 1m surrounding the plant at a depth of 100mm. Mulch should not touch plant stems. Mulch
can also be used in areas awaiting rehabilitation (and landscaping) to suppress weed growth.

3.5.5 Watering

Water crystals are to be placed at the bottom of planting holes and in contact with plant roots (if the water
crystals do not contain additional fertiliser). All plants are then to be watered in at planting (approximately
5 — 10L) and as required in the establlshment and maintenance periods that follow. Note that Council
watering restrictions may apply.

Performance criteria:

   

At the completion of the rehabilitation works, an on-maintenance period of 12 months will commence. Maintenance
of the rehabilitation areas will continue until the end of the on-maintenance period;

Control of weed species will be undertaken within each rehabilitation zone on a monthly basis for 6 months tollowing
the completion of revegetation works, then quarterly until canopy cover suppresses weed germination and growth.
Regular inspections and monitoring jeed-back will inform weed removal during the 12 month maintenance phase.
Mechanical weed control will be used as the preferred option where possible;

Where mortalilies of planted stock occur, they will be replaced with similar species consistent wilh the planting
prescriptions within two (2) months (or at suitable planting periods);

Growing stock will be watered at planting and on a needs basis depending on weather conditions during the
establishment phase. itis anticipated that plants will require watering on a weekly basis during the first eight weeks
and then on an as needs basis for the next six months during the establishment period. Rainfall periods may reduce
these watering requirements;

Detailed maintenance schedule is provided in Appendix B;

Regular monitoring over a 12 month period will be required at the completion of the rehabilitation works. Monltoring |
should be undertaken by a suilably qualified person (i.e. restoration ecologist). As a minimum the following will be
monitored:

= Weed control— extent and adequacy as well as any secondary weed responses to treatments;
= Presence of specific environmental weeds;

= Indicators of growth and survival of all plantings;

= Adequacy of site preparation, mulching, tree (and plant) protection and maintenance; and

= Adequacy of flow of information from ecological and project monitoring back to the contractor, and subsequent
response and integration of any modifications.

Monitoring should be undertaken at the completion of the revegetation works, then every three months for 12 months
post rehabilitation. The monitoring schedule may be required to be adapied if changes fo rehabilitation ,
works/pragress occurs; and

Brief report should accompany each monitoring period and should summarise the findings of monitoring events and |
identify the performance of rehabilitation works wilh reference to the objectives of this plan and performance criterla |
listed below. Where the objectives / criteria are not being achieved, ihe report should recommend relevant actions |
required to amend this situation. |

=  Mulched cover maintained around planted species;

«All mortalities replaced;

= Wo to minimal weeds;

= All vegetation strata's (i.e. ground layer, shrub, understorey tree & canopy) present; and

» All planted species showing evidence of heallh and vigour {i.e. new growth) and appear well established.

4.4 Roles &

 

Contractors undertaking rehabilitation works must be instructed directly of the requirements of this plan. A
copy of this ERP is to be retained and displayed on site at all times during rehabilitation activities. The site
manager should ensure that all relevant contractual documents specify the ERP as a responsibility. The
roles and responsibilities assigned to individuals are outlined in Table 4.1.

APPENDIX A PLANTING PALETTE

The species assemblage and target densities outlined below are based on that which currently occurs within
the parkland area, database results of locally occurring species, species assemblage of the RE communities
and local knowledge. It should be noted that producing a floristically diverse community is important in order
to create a functioning ecosystem. It is acknowledged that the planting area Is relatively small, however this
list is considered a guide for rehabilitation planting and certain species may also be considered for
landscaping purposes.

Koala Habitat Management Plan - 215-219 David Low Way, Peregian Beach

 

1 INTRODUCTION
1.1 Background

James Warren and Associates (JWA) have been engaged by Matrix Projects (QLD)
Pty Ltd to prepare a Koala Habitat Management Plan (KHMP) for the development
at 215 - 219 David Low Way, Peregian Beach. This KHMP has been prepared for
submission to the Department of Infrastructure and Planning (DIP) in accordance
with the development approval conditions.

The Koala Habitat Management Plan has been designed to guide the management
of Koala habitat occurring within the subject site. This plan shall demonstrate how
Koala habitat values are to be protected or enhanced, including how threats to
Koala habitat values will be mitigated. The KHMP will outline the actions to be
completed in order to manage habitat and vegetation prior to, during and post
construction.

1.2 Site Description

The subject site is formally described as Lots 8 - 10 on P9315 and Lot 76 on
MCH2969 and is located at 215 - 219 David Low Way, Peregian Beach (FIGURE 1).
The site covers an area of approximately 2.3ha.

The subject site has previously been selectively cleared and is currently operates
as a caravan park. The western boundary of the subject site adjoins to Noosa
National Park. An aerial photograph of the subject site is shown in FIGURE 2.

1.3 The Approved Development

The subject site has been approved to be developed for the purposes of
commercial and visitor accommodation precincts. The approved development will
consist of sixty-four (64) shared visitor individual units within two (2) buildings, an
additional thirty (30) dwelling units and associated infrastructure (FIGURE 3).
Associated infrastructure includes access roads, car parks and visitor facilities such
as BBQ areas, playgrounds and a pool.

1.4 Objectives
The overall performance objectives of this management plan are as follows:
e Site preparation shall be completed in accordance with the environmental
procedures for vegetation management. The KHMP will identify measures to

2 KOALA HABITAT ASSESSMENT
2.1 Introduction

In order to assess the Koala habitat values within the subject site and surrounding
areas, current RE mapping and Koala habitat mapping was reviewed and a targeted
search for indicators of Koala presence and/or use was completed across the
subject site. Aerial photography for the site was obtained prior to completing the
field surveys. An aerial photograph of the subject site is shown in FIGURE 2.

2.2 Methodology

2.2.1 Regional Ecosystem Mapping

Current (Version 6.0) Regional Ecosystem Mapping was obtained from the
Department of Environment and Resource Management (DERM) website using the
Lot and Plan number of the subject Site.

2.2.2 Koala Habitat Mapping

Current (November 2009) SEQ Koala State Planning Regulatory Provisions Mapping
was obtained from the Department of Infrastructure and Planning (DIP) website
using the Lot and Plan number of the subject Site.

2.2.3 Site Assessment

All potential Koala habitat trees occurring on the site were inspected for the
presence of Koalas or indicators of Koala presence (i.e. faecal pellets or scratch
marks).

This assessment was completed by one (1) scientist from JWA on the 29th March
2010 for approximately one and a half (1.5) hours.

2.3 Results

2.3.1 Regional Ecosystem Mapping

Current Regional Ecosystem Mapping indicates that there are two (2) Regional
Ecosystems (RE’s) located within the subject site (FIGURE 4). RE 12.2.7 (Least
Concern) and RE 12.2.12/12.2.15 (Least Concern) are both mapped as occurring in
the western portion of the subject site. RE 12.2.7 is described as Melaleuca
quinquenervia or M. viridiflora open forest to woodland on sand plains. RE
12.2.12/12.2.15 is described as Closed heath on seasonally waterlogged sand
plains/ Swamps with Baumea spp., Juncus spp. and Lepironia articulata.

2.3.2 Koala Habitat Mapping

A review of the current SEQ Koala State Planning Regulatory Provisions mapping
revealed that the entire subject site is mapped as an Interim Koala Habitat
Protection Area (FIGURE 5). It should be noted that although the entire site is
mapped as Koala habitat, the majority of the eastern portion of the subject site
has previously been cleared of native vegetation.

2.3.3 Results of Site Assessment

No preferred Koala food trees were observed on the subject site. The Broad-leaved
paperbark (M. quinquenervia) was the only flora species recorded from the subject
site that is considered to potentially provide Koala habitat. Fifteen (15) mature
specimens of Broad-leaved paperbark were inspected for the presence of Koalas or
indicators of Koala activity.

Despite targeted searches of these trees, no Koalas or indicators of Koala presence
were recorded from the site. That is, no faecal pellets or scratch marks
attributable to the Koala were observed on the subject site.

Although the subject site lacks preferred Koala food trees, the western portion of
the site does provide potential Koala habitat areas. All vegetation within the
western portion of the site will be retained as the western allotment is to be
dedicated as a reserve. No indicators of Koala presence (i.e. faecal pellets and/or
scratch marks) have been recorded within these habitat areas. Consequently, the
subject site is not considered to function as a Koala movement corridor.
Regardless, Koalas may occur on the site given the close proximity to Noosa
National Park (FIGURE 1).

2.4 Summary

Although a number of potential habitat trees were recorded within the subject
site, no preferred Koala food trees were recorded. The site assessment also failed
to detect any Koalas or evidence of Koala activity within the subject site.
Consequently, the subject site is not considered to provide significant habitat or
corridor values for the Koala.

The subject site does occur adjacent to Noosa National Park, an area which may
potentially provide habitat for Koalas. A balance lot conservation area will be
retained in the western portion of the subject site. It is intended that the
development will incorporate Koala friendly design features to ensure that the site
remains permeable to Koalas.

3 VEGETATION MANAGEMENT

3.1 Background

In order to protect the ecological values of the site, vegetation management
practices will be of the highest importance during the clearing and construction
phases of the development. The methods proposed to ensure the protection of
native vegetation are discussed below.

3.2 Extent of Vegetation Disturbance

The construction of access roads, services and stormwater treatment devices will
require bulk earthwork activities. During this time, any existing trees identified for
retention will be protected from nearby vegetation disturbance activities. Detailed
information regarding vegetation retention and protection will be provided in both
the Arborist’s report and the Ecologist’s revegetation plan for the dedicated
western balance lot.

This area will be clearly identified and access to the area will be restricted prior to
the commencement of any earthworks.

3.3 Vegetation Protection Measures

This section outlines the following recommended measures to minimise potential
impacts on existing trees and areas of vegetation to be retained:

e Instructions to Vegetation Site preparation Contractors/Site Managers;

e Installation of vegetation protection measures e.g. temporary exclusion
fencing during site preparation operation;

e Vegetation management prior to, during and following site preparation
operations; and

e Long-term management and protection of vegetation retention areas.

All vegetation to be retained shall be protected from the following possible on site
disturbances:

a Earthworks;

. Construction of pathways;

. Machinery storage;

. Site waste dumping;

: Stockpiling of mulch/chipped material or soil;
. Erosion;

" Unauthorised vegetation removal;

" Herbicide application; and

. Introduction of declared weed species.

Contractor shall identify all native vegetation to be retained across
the development site on construction plans and in the field.

All vegetation retention areas will be fenced and clearly identified as
a ‘Vegetation Protection Area’ prior to the commencement of any
works on the subject site. These exclusion fences shall be maintained
throughout the construction period. Access to vegetation retention
areas will only be allowed for the purposes of weed removal by a
suitably qualified restoration team. Within these zones the following
activities shall not be permitted:

Storage and mixing of materials;

Vehicle parking;

Liquid disposal;

Machinery repairs and/or refuelling;

Construction site office or shed;

Combustion of any material;

Stockpiling of soil, rubble or debris;

Any filling or excavation including trench line, topsoil skimming
and/or surface excavation, unless otherwise approved by the
Project Manager; and

e Unauthorised pesticide, herbicide or chemical applications.

All activities in an area adjacent to any protected vegetation shall be
carried out in such a manner as to minimise any damage to trees and /
or the conserved area.

Tree limbs (of trees to be retained) that are likely to be in the way of
earthworks shall be pruned by a qualified tree surgeon prior to
construction activity commencing.

Tree roots (of trees to be retained) that are likely to interfere with
machinery shall be cut (by a qualified tree surgeon or horticulturalist)
and the remaining roots shall be treated with a suitable fungicide.

The erosion and sediment control measures shall be in accordance
with the erosion and sediment control plans.

The Project Manager shall undertake inspections on a weekly basis
during the construction phase to ensure that all recommendations are
being followed.

3.4 Vegetation Removal and Disposal Methods

Clearing outside vegetation retention areas shall occur in the sequence of cutting,
shearing of felled vegetation and tub grinding. Upon completion, grubbing
operations shall ensure the site is left free draining with no ponding of stormwater.

Any cleared native vegetation is to be chipped and utilised as mulch on site where
possible. Mulch stockpiles are to be less than 1000 cubic metre, less than 2.5
metres high and a minimum of 10 metres between edges of heaps. Declared and/or
environmental weeds shall be disposed of at an appropriate Council green waste
facility.

3.5 Long-term Management and Protection of Retained
Vegetation

This section outlines provisions that shall ensure the long-term management and
protection of retained vegetation. The management protocols that will be required
following the completion of the development are as follows:

i No native vegetation shall be removed from the Balance lot
conservation area.

ii. Herbicides should only be applied in accordance with the weed
management practices provided within this document or an approved
Rehabilitation Plan for the site. No herbicides are to be applied to
native vegetation.

iti. All vegetation retention areas will be fenced and clearly identified as
a ‘Vegetation Protection Area’.

iv. The Applicant shall ensure that pathways are not constructed within
vegetation retention areas.

v. The Applicant shall be responsible for ensuring that all areas of
retained vegetation are monitored for edge-effects, erosion,
environmental weeds and undertake appropriate remedial actions
when required.

vi. The Applicant is also responsible for ensuring the ecological integrity
of vegetation retention areas by removing weeds on a regular basis.
Weeds shall not be allowed to become established to levels that
threaten native vegetation.

vii. The Applicant is responsible for ensuring that no rubbish is introduced
into an area of retained vegetation. In the event that rubbish comes to
be within the boundaries of a vegetation retention area, the Applicant
will be responsible for the removal of such rubbish as well as any
associated costs.

4 WEED AND PEST SPECIES MANAGEMENT

4.1 Background

No declared plant species as listed under the Land Protection (Pest and Stock
Route Management) Act 2002 are to be introduced to the subject site during
construction. This includes introduction through the use of topsoil or mulch in
landscaping areas.

Weed removal within any areas of retained vegetation is to be conducted by
experienced personnel with training in weed identification and management. Weed
removal activities are to be limited to those that do not pose a threat to native
flora. Suitable methods include manual removal or targeted herbicide application.
Where herbicide use is considered necessary within 50m of riparian areas, only
chemicals that are readily biodegradable and suitable for aquatic environments (ie,
Glyphosate Bioactive or equivalent) are to be applied. Weed control techniques
have been recommended for the various weed growth forms (i.e. grasses, herbs,
shrubs, etc.) which may occur on the site.

4.2 Weed and Pest Management Protocols

This section outlines provisions that shall prevent weed and pest species being
introduced to the site, whilst ensuring existing weed and pest species are managed
appropriately. The weed and pest management protocols to be implemented during
construction, landscaping and rehabilitation works are as follows:

i. All nursery stock shall be weed, pest and disease free and certified as
such by the supplier where feasible. The certificates are to be
obtained prior to the commencement of any
regeneration/revegetation works on site and shall be made available
to Council upon request.

ie All mulch produced on site by mulching cleared vegetation and trees
shall specifically exclude material from weed species. Vegetation
mulching will be suitably controlled to avoid contamination. Mulch
containing weed species material shall be treated separately and not
used on site for regeneration/ revegetation works.

iii. Soil disturbance within vegetation retention areas shall be avoided to
prevent weed recruitment. Areas to be regenerated (weed control) or
revegetated shall be completed under strict supervision to avoid
unnecessary soil disturbance. Areas to be regenerated/ revegetated
would be identified and demarcated prior the commencement of any
works in the revegetation areas.

iv. Weed control and regeneration/revegetation in the vegetation
retention areas shall be completed using suitable and appropriate
strategies as employed elsewhere within the Council area and in
accordance with this Koala habitat Management Plan.

 

Q10024/HB/Final JAMES WARREN AND ASSOCIATES 10

Page 40

 

Koala Habitat Management Plan - 215-219 David Low Way, Peregian Beach

v. Weed or potential weed species shall not be planted during
landscaping operations.

vi. All Class 2 and Class 3 weeds declared under the Land Protection (Pest
and Stock Route Management) Act 2002 and Regulations 2003 and all
environmental weed species listed by Sunshine Coast Regional Council
that occur within the subject site shall be eradicated.

Vii. Pest animal control measures, where necessary, shall be completed
using suitable and appropriate strategies as employed elsewhere
within the Council area.

viii. Unrestrained dogs shall not be allowed on the site during construction
and a restriction of dogs (and other domestic animals) within the
subject site shall be implemented.

ix. All. stormwater treatment and sediment control devices shall be
designed and managed so they do not create breeding habitat for
mosquitoes and cane toads (eg. ponds of standing water).

x. Construction activities shall be carried out in such a way so as to
prevent the creation of ponded or standing water, which would result
in breeding habitat for mosquitoes and cane toads.

5 LANDSCAPE MANAGEMENT

The intention of the landscape works within the proposed development is to select
native trees that will;

Replace Koala habitat trees removed as a result of the development;
Continue the landscape character of existing native vegetation within and
surrounding the subject site;

Be visually appealing to help promote and market the proposed
development; and

Be compatible with the existing site attributes and proposed development
conditions.

A Landscape Plan will be prepared for the subject site in accordance with the
approval conditions. Landscape areas throughout the development will be planted
with Koala habitat trees where appropriate. The preferred Koala habitat tree
species to be used for landscape plantings within the development area are shown
in TABLE 1.

6 FAUNA MANAGEMENT

6.1 Operational Works

Construction phase fauna management should include the installation of temporary
exclusion fencing.

6.2 Fauna Movement

6.2.1 Background

As previously mentioned, the western boundary of the subject site adjoins to Noosa
National Park. It is intended that the interface between the development area and
the retained habitats will remain permeable to Koalas and other native fauna. The
retention of vegetation in the dedicated western lot will provide fauna habitat
allowing Koalas and other fauna species to move safely between the subject site
and Noosa National Park.

6.2.2 Fauna Friendly Fencing

The interface between the vegetation retention area and the development area
will be completed by use of a 1m high gabion basket fence in accordance with the
ROL application and approved Stormwater Management Plan. Alternative styles of
fauna friendly fence such as post and rail with a minimum gap of 300mm between
rails should be used in the event that the remaining boundaries of the subject site
are to be fenced. These fauna friendly fences have been designed to ensure that
fauna movements between the subject site and adjoining lands shall continue
following the completion of development.

6.2.3 Barrier Mitigation

David Low Way occurs as a major barrier to the east of the subject site. Minor
roads will also be constructed within the development site. In order to minimise
the impact of these roads on fauna movements, low traffic speeds will be
implemented across the development area. Street tree plantings will incorporate
the use of preferred Koala habitat trees as outlined in Section 5.

6.2.4 Koala Friendly Pool Design

The proposed pool will be designed with a shallow lagoon-style entry where the
pool water is level with part of the surrounding pavement. The proposed pool
design is considered to comply with the Queensland Government’s Koala Safety
Fencing and Measures Guideline (December 2009) (KSFM Guideline).

6.3 Non-native Fauna Management

A range of exotic fauna are likely to occur in the study area and impact on native
fauna communities, including the cat, dog and Cane toad. The most significant
impact associated with development is the introduction of exotic predators to
remnant bushland and, particularly increased numbers of cats.

 

Q10024/HB/Final JAMES WARREN AND ASSOCIATES 13

Page 43

 

Koala Habitat Management Plan - 215-219 David Low Way, Peregian Beach

 

In recent years the impact of cat predation on native Australian Fauna has become
a prominent public issue. The impacts of domestic dogs are not readily quantified.
Dogs are however, known to attack Koalas and thus should be considered a
management problem at the urban/bushland interface.

In order to mitigate the impacts of non-native fauna, all domestic animals will be
prohibited from the approved development at all times.

7 PREVENTION OF EROSION AND SEDIMENTATION

In order to minimise damage to areas of retained vegetation (within or adjacent to
the subject site), erosion and sediment control measures will be employed
throughout the development phase in accordance with the approved Erosion and
Sediment Control Plans.

Measures to protect vegetation areas from erosion and sedimentation during the
construction phase of the development are outlined below:

i. Erosion & sediment control works shall be undertaken in accordance
with an approved Sediment and Erosion Control Plan. Some issues to
be considered include:

e Minimising the area of disturbance across the development
site;

e Perimeter bunds/cut-off drains designed to by-pass upstream
“clean” runoff around the works area;

e Silt fencing and silt traps established in a manner that will
protect the areas of vegetation to be retained from erosion and
sedimentation; and

e Stabilisation of steep batters/slopes.

ii. As construction activities may impact on retained vegetation areas
(within or adjacent to the subject site) it is important to ensure
sediment fencing is in place before site preparation and other
earthworks commence. Prior to any site preparation operations the
Project Manager (or other suitably qualified personnel) shall undertake
an inspection of all sediment fencing.

iti. Upon completion of earthworks and/or grubbing operations the site is
to be left free draining with no ponding of stormwater within areas of
retained vegetation.

iv. Landscaping works within subject site are to utilise suitable native
locally endemic species where appropriate and in accordance with
approved Landscape Plans.

Summary

1, Samuel Cowie Arborist/Horticulturist and Principal of Leaf & Limb Horticultural
Consultancy, have been engaged by Matrix. [have been engaged for the purpose of
investigating and reporting on options rejated to the retention or remoyal, and protection of
the existing irees located on ihe site being developed as The Essence of Peregian, and advise
on any relevant on-going tree management that is required between trees and proposed
development works, | inspected the site and trees on the 14” of April 2010 and the 7" of June
2010. The site inspection and this report were conducted as per SCRC’s DA conditions,
specifically conditions No 17, 18, and 49, The report also addressed issues with condition No
16. This forms the brief of the report.

 

   

Condition No 16

Given the extensive nature of the bulk earthworks agross the majority of the site. the overall
age/poor health and structure of the Melaleucas on the site, retention of any trees outside of
the building footprints isn’t possible for a long-term health and structural arboricultural
perspective.

 

Condition No 17

The requirement to install sheet piling outside of the building located in the south-castern
corner of the site will impact heavily on Trees No 1, 2,3 and 4. Tree No | has a poor
retention value due to the basal structural defect and poor useful life expectancy, where as
Trees No 2, 3 and 4 will be severely impacted by the sheet piling. Combined with their
overall small stature, therefore lacking significance when compared to larger trees, removal
and replacement of all 4 trees is the best option and will increase the future teeescape of the
nature strip and site.

‘Tree No 5 is neither in good health or structure, therefore removal and replacement with a
supertor specimen at the landscape phase is the best option.

Tree No 6 has a short useful life expectancy due to the loss of a major first order branch,
including a major future structural issue, therefore the retention value is low and removal is
recommended.

 

Trees No 7, 8 and 9 are also poor specimens for retention, This is due to their advanced age
and prevalence of the decay fungus Phellinus throughout their branch structure. The client
requests and prefers the retention of these trees, and given the driveway footprint, retention
maybe possible under supervision of a qualified sit arborist and as per AS4970-2009.

Condition No 49

Assessment of the KIIMP by James Warren and Associates found no trees specified for
relention due to Koala activities, therefore the requirements of this condition aren't
applicable.

Tree Prviection (Wesiern Reserve)

Although not addressed under the conditions of DA consent, the trees and vegetation located
on the western side of the gabion wall are retainable (no obvious impacts or future targets in
their vicinity}, Protection of the vegetation and trees maybe done by installation of
appropriate fencing and signage with the assumed erosion contro! measures placed on the
western side of the gabion wall during construction,

Tree Protection prior, during and after development works
‘The tree management and protection plan recommended in this report (6.3) should be
implemented to preserve and relain trees numbered 7, 8 and 9 if requested by the client.

Introduction

I, Samuel Cowie Arborist/Horticulturist and Principal of Leaf & Limb
Horticultural Consultancy, have been engaged by Matrix. I have been
engaged for the purpose of investigating and reporting on options related to
the retention or removal, and protection of the existing trees located on the site
being developed as The Essence of Peregian, and advise on any relevant on-
going tree management that is required between trees and proposed
development works.

I inspected the site and trees on the 14" of April 2010 and the 7” of June 2010.

The site inspection and this report were conducted as per SCRC’s DA
conditions, specifically conditions No 17, 18, and 49. The report also
addressed issues with condition No 16. This forms the brief of the report.

Methodology

Identification of plant material was conducted using Barwick (2004), Rowell
(1983) and Haslam (2004). All references to pruning are taken from AS 4373-
2007, Pruning of Amenity Trees. Assessment of the trees was conducted
using Visual Tree Assessment (VTA) from Mattheck (1994 & 1999), with
additional references from Matheny & Clark (1994), and Harris (1999 &
2004). Any risk assessment was done using Quantified Tree Risk Assessment
(QTRA version 2007). Additional references to tree anatomy and structure are
taken from Shigo (1986 & 1991), including references to roots from Perry
(1982) and Urban (2008). Specifications on protection of trees and tree roots
during construction activities are taken from AS 4970-2009 and BS
5837:2005, including additional references from Urban (2008).

Mr Clint Sloan of Matrix provided all information in relation to current plans,
reports etc.

A Pentax Optio A30 digital camera set on the highest resolution possible (10
Mega pixels) was used for photographic documentation. A diameter tape was
used for all measurements, giving an average diameter based on the
circumference measurement. Diameter at Breast Height (DBH) was taken at
1400mm above ground level on the highest side of the trunk, or as per

AS4970-2009.

No soil or root excavation assessment was carried out during the time of
inspection. Root mapping where specified was done by obvious and visual
signs of disturbance to the soil, surrounding structures and obvious surface
roots.

3 Observations

321 The Site
The site is known as Lots 8-10 on P9315 and Lot 76 on MCH2969 and is
located at 215-219 David Low Way, Peregian Beach QLD (as described by the
Koala Habitat Management Plan by James Warren & Associates, for the site).
The area specifically addressed in this report is the area of the site impacted by
development, specifically those shown on the bulk earthworks plans by TOD
Consulting Engineers (see Appendix A- Bulk Earthworks Plan). The area on
the western side of the gabion wall (Appendix A) is assumed to have no
development impacts, for example soil movement or disturbance.

Site soils weren’t assessed during inspection, although casual inspection found
them to be sandy. Considering the habitat of the surrounding area, available
soil depth for root growth is limited by the water logged, and/or relatively high
water table that are preferred by the endemic Melaleuca quinquenervia.

The area is currently used as a caravan and camping site.

3.2 Approved Development
The site has been approved for commercial and visitor accommodation
consisting of 2 buildings with a total of 64 units, and thirty other units, either
duplex or freestanding.

3.2.1 Building and Earthworks Plan/Tree Impact
DA condition No 16 addresses retention of trees outside of the approved
building layout footprint. Given that this affects the majority of trees on the
site, attention was then focused on the bulk earthworks plan that affects the
remaining trees outside of building footprints.

Comparison of the existing contours with the new levels on the bulk
earthworks plan (TOD Consulting Engineers, Job No 10525, Dwg No C4 and
C5) found that from the Gabion wall there is an increase of between 300mm
and 1000mm at the turfed fire trail. The western line of buildings will require
an 800 to 1300mm increase in soil level over the existing soil levels.

Increases over the existing soil RL’s continue until approximately the 5-metre
contour, then becomes a cut for the main unit complex in the northeast corner
of the site. The same occurs for the building in the southeast corner, where the
bulk earthworks level is 6.20 metres, which will require up to 2800mm of cut.
This is evidenced by the requirement for sheet piling around the south, east
and northern side of the building footprint.

Areas of undisturbed natural ground level are limited to the section inside the
entrance turnaround, and the area along the southern boundary at the eastern
end, or eastern side of the entrance to the development, bar impacts from sheet
piling installation (a required minimum 1200mm from the building footprint).

3.2.2. Koala Habitat Management Plan

33

3.3.1

DA condition No 49 addresses retention and protection of trees identified in
the Koala Management Plan. Review of the KHMP by James Warren &
Associates found that the site is mapped as an interim Koala Habitat
Protection Area (KHMP, page 5 & Figure 5).

Site assessment by James Warren & Associates found no preferred Koala food
trees on the subject site. Their inspection also found no evidence of Koala
activity within the site, therefore they conclude the site isn’t considered a
movement corridor for local Koalas.

Given this assessment there is no requirement for this report to address any
trees as per DA condition No 49.

The Trees

Tree Survey
The trees surveyed during inspection were dealt with as a group, with some

individuals outside of any significant impacts assessed for retention value.
Several points were noted during inspection and assessment.

The bulk of the trees on the site are mature to over mature Melaleuca
quinquenervia that have been retained from when the caravan park was first
constructed or the area was cleared. Several recorded whole tree failures have
occurred recently, mainly due to basal decay and cavities (see Photo Nol and
2). The majority of the trees have significant structural issues due to old age
and damage that has occurred to their trunks and major roots over the lifetime
of the park. No natural replacement tree germination or new tree plantings
seem to have been done over the lifetime of the park.

DA condition No 17 specifically addresses the significant trees in the
frontages of the site (excluding palms) and requests that they be retained as far
as practical.

The trees fronting onto David Low Way and Grebes Street were therefore
individually assessed as to their viable retention (see diagram No 1).

Tree No 1- Cupaniopsis anacardioides (c.n. Tuckeroo) located near the
existing retaining wall and just inside the property boundary was found to

have a significant basal wound and structural defect that limits its longevity in

a safe and useful form. Retention value is very poor.

Trees No 2, 3 and 4- weren’t identified. Trees No 2 and 4 are located outside
of the property boundary and are therefore council owned (see Photo No 3).
In regards to significance, although visible from David Low Way, none would
be considered significant to the overall treescape due to size. Discussion with
TOD found that sheet piling will be installed a minimum 1200mm outside the
building wall where excavation is need, therefore impacts on the root systems
of all three trees will be almost to their trunks.

trees outside of entrance turnabout.

Tree No 5- Lophostemon confertus (c.n. Brush Box). This is a multiple trunk
specimen that appears to be regrowth off a stump. Overall condition was poor.
Retention value is regarded as very poor due to health and structure (see Photo
No 4).

Tree No 6, 7, 8, and 9- Melaleuca quinquenervia (c.n. Broad Leaved
Paperbark). These trees are all regarded as mature.

All 4 Melaleuca quinquenervia were identified as having multiple infections
of the decay fungus Phellinus robusta (see Photos No 5 to 7). Fruiting bodies
were seen to infect all parts of the trees, particularly the main branches and
canopy structures, probably one the greatest examples of the fungus in one
spot (personal observation).

Tree No 6 has lost a major first order branch from its southern side (see Photo
No 8), therefore opening up the heartwood of the trunk to decay or further
decay depending on the prevalence and spread of Phellinus within the tree.
Overall retention value is regarded as very poor due to this major structural

problem, particularly given the high target frequency that the area will
become.

The remaining trees 7, 8 and 9 also represent very poor retention values due to
their current age and the prevalence of Phellinus robusta throughout their
branch structures.

Discussions

VTA- Visual Tree Assessment

All trees surveyed were assessed using Visual Tree Assessment (VTA). VTA
is a method of assessing trees devised by Dr Claus Mattheck (1994 & 1999).
This method is a continuation and addition to books on hazard evaluation by
Matheny & Clark (1994) and Harris (1999 & 2004) that are used to assess
both the health (biological) and structure (mechanical) of trees.

VTA takes into account biological factors such as vitality (leaves, bark, twig
growth etc), presence of fungi, old branches, wound occlusion or woundwood
development and/or compartmentalisation, and other biological factors that
contribute to tree growth. For example Tree No 5 is in poor health, obvious by
the lack of foliage cover, increased amount of deadwood and poor growth.

The second part of VTA deals with tree structure or the mechanical aspects of
trees such as breakages (defect symptoms such as bulges or ribs, wounds,
leaning that causes transverse cracks, bark cracks and other abnormal things)
and wind throw (root buttresses, soil cracks, sail area, bottle butt etc). For
example Tree No 6 has a previous failure of a major branch, where as Trees
No 7 to 9 are riddled with the decay fungus Phellinus, therefore reducing
structural integrity and useful life expectancy (part of the biological section of
VTA as well).

4.2

If there is cause for concern and further details are required for a full
assessment then the use of diagnostic tools such as Resistograph ®, Picus®,
increment borers, soil excavation for root assessment, and Fractometer®
testing are used. From either the initial visual assessment or the use of
diagnostic tools, failure criteria may be given for each tree assessed, and an
informed decision is reached for recommendations.

VTA may be used to state to what extent a defective tree is at greater risk of
breaking or failure, compared with a completely sound one. In QTRA this is
shown as the PoF or in retention value this may result in a lower value.

Tree Protection Methods and Roots

Tree protection involves the minimising of damage to the tree’s root and
vascular system during activities such as construction or installation of root
barriers, thus reducing the chance of tree health decline or death, and the
possible damage to the structural stability of the tree from root damage.
Failure to maintain a minimum tree protection zone may result in declining
long term vigour, health and structural stability in a tree on a construction site.
All trees to be retained on a construction site should have protected root zones
that are measured off the DBH of the trunk via either the Matheny & Clark
(Harris 2004, & Matheny & Clark 1998) formula, the British Standards (BS
5837:2005) for protecting trees, or the newly released Australian Standards
(AS 4970-2009 Protection of Trees on Development Sites).

Using the Matheny & Clarks method a previous understanding of a tree
species tolerance to disturbance (good, moderate, or poor) is required to work
out the Tree Protection Zone (TPZ). This distance calculation is simplified
under BS 5837:2005 where a trunk diameter (DBH) times 12 is used, the same
for AS 4970-2009. Therefore for this report and management of the tree
protection during development, the measurement of TPZ is taken from AS
4970-2009 to calculate impacts and their effects on the trees.

In relation to the majority of trees across the site, where fill will be greater
than 300mm the retention of trees becomes impossible. Assessment of the
bulk earthworks plan indicates that fill will surround all trees, not just one side
or part of their required TPZ. Generally fill over tree roots results in reduced
aeration of the root zone, therefore leading to root death or dieback, and finally
in most instances tree death.

Although instances of fill near Melaleuca quinquenervia have been found to
have a minimal effect on the tree species under the right situations (personal
observations), given the overall age, poor health, and structural condition of
the Melaleuca’s on the site and the extensive nature and depth of filling across
the site, the result would be tree death and or increased whole tree failures in
the future.

5 Conclusions

5.1 Condition No 16
Given the extensive nature of the bulk earthworks across the majority of the
site, the overall age/poor health and structure of the Melaleucas on the site,
retention of any trees outside of the building footprints isn’t possible for a
long-term health and structural arboricultural perspective.

5.2. Condition No 17
The requirement to install sheet piling outside of the building located in the
south-eastern comer of the site will impact heavily on Trees No 1, 2, 3 and 4.
Tree No 1 has a poor retention value due to the basal structural defect and poor
useful life expectancy, where as Trees No 2, 3 and 4 will be severely impacted
by the sheet piling. Combined with their overall small stature, therefore
lacking significance when compared to larger trees, removal and replacement
of all 4 trees is the best option and will increase the future treescape of the
nature strip and site.

Tree No S is neither in good health or structure, therefore removal and
replacement with a superior specimen at the landscape phase is the best option.

Tree No 6 has a short useful life expectancy due to the loss of a major first
order branch, including a major future structural issue, therefore the retention
value is low and removal is recommended.

Trees No 7, 8 and 9 are also poor specimens for retention. This is due to their
advanced age and prevalence of the decay fungus Phellinus throughout their
branch structure. The client requests and prefers the retention of these trees,
and given the driveway footprint, retention maybe possible under supervision
of a qualified sit arborist and as per AS4970-2009.

i] Condition No 49
Assessment of the KHMP by James Warren and Associates found no trees
specified for retention due to Koala activities, therefore the requirements of
this condition aren’t applicable.

5.4 Tree Protection (Western Reserve)
Although not addressed under the conditions of DA consent, the trees and
vegetation located on the western side of the gabion wall are retainable (no
obvious impacts or future targets in their vicinity). Protection of the
vegetation and trees maybe done by installation of appropriate fencing and
signage with the assumed erosion control measures placed on the western side
of the gabion wall during construction.

6 Recommendations

6.1 Tree Removal
The trees specified in 5.1 and 5.2 of this report are removed prior to
development and replaced with suitable species during the landscaping of the
finished development. This should be addressed in the Landscape Plan.

Trees No 7, 8, and 9 are recommended for removal due to their age, the
prevalence of Phellinus, and the future activities/target frequency around them
after development, but the client wishes to retain them as part of the
development. If this is the case, the Tree Management and Protection Plan in
6.3 of this report is to be implemented.

6.2 Tree Protection (Western Side)
Tree protection fencing and signage should be installed on the western side of
the gabion wall location (see Bulk Earthworks Plan by TOD Consulting
Engineers). This fencing should be installed with any erosion control
measures for that area of the site. Access to this area should only be done
under the supervision of the consulting arborist to the site during construction.

6.3 Tree Management and Protection Plan (Trees 7, 8, and 9)
The following tree protection plan is recommended if trees 7, 8, and 9 are to
be retained.

The following tree protection procedures are to be undertaken during the development
of the site to insure the safe, healthy, and long-term retention of retained trees
(numbered 7, 8 and 9 in the arborist report by Leaf & Limb Horticultural
Consultancy) identified in the operational works approved by Sunshine Coast
Regional Council. This document is to read in conjunction with the Arborist Report
prepared by Leaf & Limb Horticultural Consultancy for the site.

A laminated copy of these tree protection procedures is to be attached to any tree
protection fencing on the site, and a copy is to be retained on site by the building
contractor supervising the project.

The area within the Tree Protection Zone of any protected tree will be mulched to a
depth of 75mm with composted wood and leaf mulch (created by tree chipper), which
contains no soil fines. The TPZ is to be irrigated once per week or have five 200-litre
drip drums installed (filled twice a week).

Pre Construction

e Prior to construction works, a site arborist shall be contracted to supervise all
tree protection procedures detailed in this document. The site arborist is
required to have a minimum level 5 AQS qualification in Arboriculture, and a
minimum 5 years experience in tree protection on construction sites. Their
details are to be filled in on all tree protection fencing signage.

e Prior to construction works, a tree contractor shall be contracted to conduct all
pruning operations detailed in this document or instructed to by the site
arborist. The tree contractor cannot be the site arborist due to perceived
conflict of interest. The tree contractor must have a minimum level 3 AQS
qualification in Arboriculture, and be able to follow AS4373-2007. Their
details are to be filled in at the top of the document.

Prior to construction works, the site arborist should consult with the
construction company to outline appropriate tree protection methods during
construction, to convey the importance of tree protection, and open
communication channels.

The construction company is responsible for all tree protection procedures on
the site as per these specified recommendations, whenever the site arborist is
not on site. It is the responsibility of the builder to advise the site arborist of
when their presence is required on site or of any breaches of the tree protection
procedures.

All trees being retained as specified by Sunshine Coast Regional Council on
site should be appropriately marked by the site arborist.

Tree Protection Fencing (where used or designated) is to consist of 1800mm
high chain mesh fencing as per AS 4970-2009 or similar appropriate fencing
approved by the site arborist. TPF is to be installed as per TPZ radius
measured as per AS4970-2009, 12 times trunk DBH. The site arborist
should document any modification to the TPZ or TPF.

All TPF will have signage indicating the importance of tree protection, the
arborists contact details, and that it’s a hanging offence to disregard these.

The construction workers or subcontractors working on the site are to be
informed of tree protection importance by the contractor.

The site arborist and the contractor should agree upon and designate storage,
dumping and wash areas that will not impact on any TPZ.

Any pruning or removal works required (such as deadwood removal or
clearance pruning, selective removal of Phellinus infected branches), including
root pruning, shall be carried out by the tree contractor to Australian Standards
AS 4373 —2007 ‘Pruning of Amenity Trees’.

During Construction

The site arborist shall be present to supervise any excavation, trenching or
construction located on the site that may affect any tree roots within a
designated TPZ, and shall keep a record of works to present to the project
supervisor after completion of construction.

Access within a TPZ for foot traffic will be done only as per guidelines
described within 4.5 of AS 4970-2009.

Absolutely no machinery traffic is allowed within a TPZ.
Where possible the first 500mm of any excavation should be dug by hand or

other appropriate method designated by the site arborist to identify any
significant tree roots (25mm or greater in diameter).

e Grabbing and tearing of tree roots by machinery is prohibited, and the
contractor responsible will become liable for any arboricultural work to rectify
the damage.

e No roots greater than 25mm shall be cut during construction without consent
of the site arborist. All tree roots cut are to be identified and documented by
the site arborist.

e There will be no allowed access within the fenced off tree protection zone
without the consent of the site arborist or as allowed by the installation of
methods described under 4.5 of AS4970-2009.

Post Construction

e A post construction assessment shall be undertaken by the site arborist to
determine the health and vigour of all retained trees on the site. Any
documentation that council may require will be submitted for review at this
time.

e The assessment shall include recommendations for any future pruning works
or any corrective arboricultural action to be taken if required.

¢ The site arborist will liaise with the landscape architect and landscaper so as to
minimise any disturbance to the retained trees on the site during landscaping.
If at any point landscape works are identified that may cause damage to the
trees, the site arborist is to work with the landscaper to eliminate detrimental
impacts.

Work or construction that is contrary to these guidelines shall make the person
responsible, or liable for any damage to any tree.

If the work or construction contrary to these guidelines results in the loss of any tree,
implementation of remedial arboricultural procedures, and/or required removal of any
tree, the person responsible is liable for any cost incurred for these actions, in addition
to any fines imposed by Sunshine Coast Regional Council.

If this work or construction results in the loss of any tree, a tree valuation (Thyer’s
Method based on the tree condition prior to construction) undertaken by the site
arborist will determine the amount of compensation available to the owner of the
property, on and above any other costs incurred by the person responsible.

At no point are these guidelines finite, and at anytime the site arborist may designate
additional procedures or requirements to protect the trees on the site when required.
