Attunga Heights Rehabilitation Specification 4

4.0 AIMS, OBJECTIVES & STRATEGY

 

4.1 AIM

The primary aim of the rehabilitation works is to facilitate the development of a robust and self
sustaining viable plant communities and habitat (representing a number of ecological
communities) similar to the pre-European (natural) vegetation patterns of the site.

4,2 OBJECTIVES

To ensure that areas of rehabilitation:
* Develop self-sustaining forests based on existing local vegetation communities;
¢ Provide habitat and opportunities for movement of native fauna especially for Glossy
Black Cockatoos;
e Koalas;
e The burrowing skink (Ophioscincus truncates); and

e Help to prevent soil erosion.

4.3 PRINCIPLES
The Site Rehabilitation Plan shall be based on sound ecological and environmental principles and

shall clearly demonstrate how the Environmental Values of the Site will be protected, maintained
and enhanced:
e Only native plant species that have been recorded on site or in contiguous plant
communities on nearby blocks shall be used for rehabilitation;
© These plant species shall be free of disease, environmental weeds and pests;
e Rehabilitation works shall not compromise the existing natural regenerative process and
dynamics already occurring on the Site or further disturb the existing forested areas;
e Rehabilitated areas shall be integrated floristically and structurally with adjacent existing
forest types on the site;
e The Site Rehabilitation Plan shall not utilise plant species that could pose a risk to the
Site; and
e Rehabilitation shall not contradict local environmental values of Noosa Shire, as cited by
the Noosa Plan and the Noosa Shire Planning Scheme.

4.4 REHABILITATION STRATEGY
Existing trees and shrubs throughout the site provide roosts for seed-spreading birds and will

facilitate natural regeneration. Given sufficient time and control of weeds, natural plant
communities similar to these would re-establish. Rehabilitation will also focus on areas
containing she-oaks (Allocasuarina littoralis) because of the importance of these areas as feed
trees for the Glossy Black Cockatoo.

Initial weed control and replacement planting will aim to ‘kick-start’ the on-site ecological
processes and facilitate other rehabilitation, eventually resulting in a robust self-sustaining
forested ecosystem that is similar to the pre-European vegetation patterns of the site. In effect,
