WEED MANAGEMENT

WEED SPECIES TO BE CONTROLLED

Weed management is to include the management of all environmental weeds from
Rehabilitation Area (refer RPO2 Plate A green shading) including weeds listed in the
following documents:

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

e 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;

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

° Undesirable Species 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).

MAINTENANCE PERIOD

Weed management is to comprise treatment application to all observable exotic taxa
as required. Treatment 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 a 24-month performance maintenance period.

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/waterways. 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 commencement of revegetation works.

ASSISTED NATURAL REGENERATION

The north-west corner of the Rehabilitation Area in Lot 8 exhibits moderate to high
ecological resilience and limited weed incursion, primarily due to the high soil moisture
conditions and prevalence of wetland sedges which limit the opportunity for Singapore
daisy to take hold (refer Plate C). This area is suitable to be rehabilitated via an
assisted natural regeneration technique and has been defined as Assisted Natural
Regeneration Area. The balance of the Rehabilitation Area has been defined as the
Revegetation Area and exhibits a sparse density of native vegetation in the midstorey
and understorey and a low-high level of weed presence (refer Plate D). The application
of an assisted natural regeneration technique is not deemed feasible and
comprehensive revegetation works will be required primarily in the midstorey and
understorey but also areas of the canopy.

Assisted Natural Regeneration applies:

e 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;
e 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.
