5.7 ZONE 6: INTENSIVE REHABILITATION ZONE

5.7.1 Existing Condition

This zone located around the proposed buildings and pathways will be cleared prior to
development. The canopy is currently dominated by Bribie Island Pine (Callitris columellaris).
As development is proposed in a number of locations spread throughout the site, the understorey
condition varies. In the weedy areas the vegetation is dominated by invasive species such as
Asparagus fern (Asparagus sprengeri), Guava (Psidium guajuva) and Corky passion fruit vine
(Passiflora suberosa).

5.7.2 Target Community

The target community will be a rainforest assemblage. The objective for this area is:

To restore rainforest species including dense understorey and ground layers following

disturbance

5.8.3 Management Strategies

Specific management strategies for this zone are identified in the “Landscape Package for OP
Works Approval”.
