Stage 1 Concept Covenant Area Rehabilitation Plan v1 - 60 Glenridge Drive Cooroibah

 

WEED MANAGEMENT

WEED SPECIES TO BE CONTROLLED

Weed management is to include the management of all
environmental weeds from Vegetation Protection Covenant Area
(refer RPO1 Plate A) including weeds listed in the following
documents:

. Declared plants under the Land Protection (Biodiversity Act
2014 and sub-ordinate Regulation 2016);

. Weeds of National Significance (WONS) under the
Commonwealth Government Weeds strategy;

« Invasive Naturalised Plants in South East Queensland, 2002,
Queensland Herbarium;

. Noosa Local Government Area Pest Management Plan
2015-2019;

. Undesirable Species as listed in Planning Scheme Policy 3
Landscaping Plants and Guidelines; and

. Any other exotic plants known to exhibit weed characteristics
(i.e. Invasive, competitive characteristics).

ESTIMATED SCHEDULE

Weed management is to comprise treatment application to all
observable exotic taxa as required. Treatment and assessment must
continue until declared plants have been controlled (i.e. they are
visually dead or dying). The frequency of treatment shall be
determined in conjunction with the contractor and be designed to
achieve off maintenance at the end of the three year performance
maintenance period for Stage 1 (as identified in Condition 16 & 18 of
Councils approval).

GENERAL METHODS

All works are to be conducted in line with the SEQ Ecological
Restoration Framework. All weed treatments to comply with Minor
Use Permit PER11463 & 82307, product labels and individual SDS,
and other applicable permits as well as the Chemica! Usage
(Agricultural and Veterinary) Control Act 1988, Agricultural Chemical
Distribution and Control Act 1966, and the Work Health and Safety
Act 2071 (including all applicable Regulations).

All weed management works are to be conducted by experienced
persons proficient in both native species and weed species
identification. The method adopted for removal of weeds from the
site will be dependent upon the physical stage of development of
individual weed specimens. Only herbicides registered for aquatic
use as detailed on the manufacturer’s specifications are to be
applied within or immediately adjacent to waterbodies. Herbicide
sprays should be applied in non-windy conditions in order to prevent
incidental poisoning of native species and not on days preceding
forecast rainfall. A period of three to four weeks is usually required
between herbicide application and revegetation.

ASSISTED NATURAL REGENERATION

Assisted Natural Regeneration management will be undertaken
within vegetated areas of the Covenant Protection Covenant Area as
it is dominated by existing established native vegetation with a low
level of exotic weed invasion (refer RPO2 Plate B pink shading).
Assisted Natural Regeneration applies:

. To natural areas where the native plant community is
largely healthy and functioning;
° When native plant seed is still stored in the soil or will be

able to reach the site from nearby natural areas, by birds or other
animals, wind or water;

. Where the natural regeneration processes (seedling
germination, root suckering, etc.) are being inhibited by external
factors, such as weed invasion, soil compaction, cattle grazing,
mechanical slashing, etc.;

« When limited human intervention, such as weed control, minor
amelioration of soil conditions, erection of fencing, cessation of
slashing, etc. will be enough to trigger the recovery processes
through natural regeneration; and

° When the main management issue is weed infestation and/or
current land use practices.

The re-establishing plant community will be substantially similar in

structure, composition and diversity to the original vegetation type

(based on the Regional Ecosystem (Pre-Clearing) mapping). It is

expected the general management techniques are to follow the

principles of:

1. Identifying nodes of resilience;

2. Working to strengthen identified nodes and protect and
encourage all existing and naturally regenerating species
through assisted natural regeneration processes; and

3. Working outwards from nodes of resilience to increase the size
of nodes and gradually connect to other nodes of resilience.

PERFORMANCE CRITERIA

Performance criteria have been set to provide easily identifiable and
quantitative indicators of revegetation progression.

Table 1 identifies the performance criteria to be used to assess the
success of the weed control works. These performance criteria must
be met for the works to be considered successful. The rehabilitation
works are to be assessed against these Performance Criteria to
ensure compliance with this Rehabilitation Plan.

Certification is to be issued to Council at the completion of works to
demonstrate that the rehabilitation works have achieved the
nominated Performance Criteria.

It should be noted that under the Biosecurity Act 2014 the landowner
is responsible for biosecurity matters on their land.

TABLE 1 - PERFORMANCE CRITERIA

 

Weed No live woody weeds present in the canopy &
management mid-canopy at the end of the on-maintenance
period.

Plan 2020 pest plants listed in Schedule 1 part
3, Schedule 2 and Non-scheduled invasive
species.

zone around each planted tubestock.

3 Monthly (or as required) weed maintenance
within the assisted natural regeneration areas.

 

Revegetation Mulch replenishment when required.
Tubestock are watered when required.
a. Year One — 12 months after installation:

i. Planted trees have achieved an average
height of 1m.

ji. Planted shrubs have achieved an average
height of 0.4m.

Ecological
Preservation

A “no clearing zone” must be established and
maintained over the land area defined over the
area identified as vegetation protection
covenants on the Approved Plans.

The following activities must not be carried out
within the no clearing zone:

a. clearing, cutting down, poisoning, lopping or
pruning of native vegetation which is indigenous
to, or planted within, the zone

b. soil/spoil dumping and/or compacting

c. soil excavation, other than for planting
indigenous native plants or for works which are
a natural consequence of this approval.

The following exceptions apply:

i. declared plants under the Biosecurity Act
2014, and any Council Listed Environmental
Weeds, Undesirable species, Exotic Grasses
and other plants identified in writing by Council
ii, indigenous native trees which pose a well-
founded threat to persons or property as
approved in writing by Council

ili. controlled bushfire burns to maintain
ecological processes subject to submission of a
Bushfire Management Plan and agreed in
writing by Council.
