REHABILITATION PLAN

4.1 Plan Summary

This rehabilitation plan is required to rehabilitate areas on the subject site identified
as degraded in Duke Environmental Ecological Assessment Report
(AC07631ECO). Areas of degradation were generally observed as being infested
with a variety of non-native species including several declared species as listed
under the Land Protection (Pest and Stock Route Management) Act 2002.

Refer to Appendix G in Duke Environmental Ecological Assessment Report
(AC07631ECO) for detailed species lists.

A summary of the rehabilitation plan for zones 1-4 (as identified on Drawing
DE07631/02 Sheet 01 of 02 included in Appendix A) is below.

4.1.1 Zone 1- Weed Control and Natural Recrultment

Areas designated as Zone 1 were observed as generally possessing
significant canopy cover of native species combined with some invasive
species and understorey invaded with weedy/exotic species (in some cases
significantly). For detailed vegetation community descriptions refer to Duke
Environmental Ecological Assessment Report (Ref: ACO7631ECO).
Management of these areas is to consist of thorough removal of invasive and
exotic species with particular focus on the species listed in Sections 3.1.1
and 3.2.3. Refer to Appendix D for weed control procedures.

After clearance of all invasive species, rehabilitation will rely on on-going
maintenance of the areas and natural recruitment of native species from in-
situ seed stock. We expect that by relying on natural regeneration, an
appropriate suite of species associated with several stratum will develop.

4.1.2 Zone 2—Weed Control and Supplementary River Bank Planting

Areas designated as Zone 2 were generally analogous to the eastern riparian
zone of the Noosa River, Vegetation adjoining the watercourse was observed
as degraded with patches of invasive species (Singapore Daisy in particular)
holding bank integrity stable. The banks were observed to also contain many
native trees and mangroves, acting to support the riparian zone (Refer Duke
Environmental Ecological Assessment Report (Ref: ACO7631ECQ) for
detailed descriptions). In accordance with FHMOP 001 (2002) no interference
with these riparian species is to occur.

Management of this zone will incorporate weed control and additional
plantings to supplement existing native species. Invasive species supporting
bank integrity are to be removed but additional bank support may be required
during the initial establishment of planted tube stock (eg. Jute matting with
intensive planting).

Species to supplement existing vegetation and create a buffer zone of at
least 5m width (in general accordance with FHG003 — Fish Habitat Buffer
Zones) include those observed in intact vegetation on-site incorporating trees
(at 2m x 3m centres) and ground covers (1m centres). Refer to Appendix C
(Plant Schedule) for details.
