WEED MANAGEMENT

WEED SPECIES TO BE CONTROLLED

Weed management is to include the management of all
environmental weeds from the Riparian Buffer Area including (but
not limited to) those listed in Table 2, as well as any additional weeds
listed in the following documents:

° Restricted Matters (Invasive Plants) listed under the QLD
Biosecurity Act 2014;

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

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

° Noosa Planning Scheme Policy 2 - Landscaping

. Pest plants listed in Schedule 1 part 3, Schedule 2 and Non-
scheduled invasive species within Noosa Council's
Biosecurity Plan 2020; and

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

ESTIMATED SCHEDULE

Weed management is to comprise an initial treatment application to
all observable exotic taxa as required. One follow up treatment will
also be undertaken approximately 3 months after the initial treatment
to control any remaining weed species missed or in which initial
treatment was ineffective.

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 Chemical Usage
(Agricultural and Veterinary) Control Act 1988, Agricultural Chemical
Distribution and Control Act 1966, and the Work Health and Safety
Act 2011 (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 the Riparian Buffer Area as it is dominated by existing
established native vegetation with a low level of exotic weed
invasion. 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 rehabilitation 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 Riparian Buffer Area 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.

FENCING

Condition 11 of the Decision Notice requires that a permanent fence must be constructed along the entire length of the
interface of the site with the Riparian Buffer Area. The fence must be constructed in accordance with an Operational
Works approval. The fence must be constructed to the following specifications:

a.

linework inRPO2. The fence is expected to be approximately 195m in length and consist of star pickets with 3 strands of
wire.

1.2 metres high;

3 strand plain wire (no barbed wire);

Bottom strand no less than 300mm off the ground;
Include a pedestrian access gate; and

Include A5 sized signage with the wording “Vegetation Protection Area - No domestic animals” every 15m,
durable, weather resistant and visually complementary to the natural environment.

encing is proposed generally in alignment with the edge of the covenant/Riparian Buffer area as depicted in the red
