5.5.3 Management Strategies

Attunga Heights Rehabilitation Specification 10

In order to return Zone 4 to a healthy community, intensive weed management and planting

strategies are required as outlined below.

Weed Management

Planting

Species

Other Considerations

 

 

Intensive weed control. It is
anticipated that this will involve
chemical treatment of broad
areas of weeds, in some
instances followed by brush
cutting of standing dead
material. Some areas of
manual removal may be
warranted, however care must
be taken not to destabilize the
site and provide opportunities
for weed re-establishment.
Great care must be taken to
avoid any native regeneration.

 

Planting of trees and
understorey elements both to
restore natural conditions and
to suppress weed re-
establishment. Planting
should be targeted within
areas where there are canopy
gaps resulting in light fall on
the forest floor.

 

Where required the following
species scheduled in
Attachment 2 are to be
planted. No one species is to
make up more than 20% of a
planting mix.

 

Following weed control it may
be preferential to blanket
mulch areas to minimize
opportunities for weed re-
establishment and to enhance

aesthetics. It is anticipated
that this will be required in
some areas immediately
abutting the existing

pedestrian path,

 

5.6 ZONE 5: SHEOAK PROTECTION ZONE

5.6.1 Existing Condition

A small stand of Black sheoaks (Allocasuarina littoralis) is present in this location. This area is
potentially a food source for the ‘Vulnerable’ Glossy Black Cockatoo. The understorey supports
Phebalium woombye and Persoonia virgata and includes some sparsely vegetated areas.

5.6.2 Target Community

The target community is a Black sheoak (Allocasuarina littoralis) dominated stand with a weed

free understorey. The objective is:

To protect and enhance the current stand of casuarinas and to eliminate the invasive weed

species

5.6.3 Management Strategies

In order to meet the objective for zone 5 the management strategies below are required.
