Around 15 hectares of the Park is currently native bush, with a planting programme in place to re-forest another 4 hectares. Around 2 hectares of flat land will be left as grassland to allow for the development of buildings, car parking and to provide a clean and environmentally friendly campsite for the benefit of schools, universities, and the public.
The adjacent Otanewainuku State Forest comprises a large area of native bush which has an active predator management program in place. Kiwi and Kokako have been released there and are breeding successfully. The planting of native bush and pest management at the Park will enable a bush corridor to be created between Otanewainuku and the forested gorges of the Te Rerenga stream enabling the native birds to migrate between these large tracts of native bush. In the future, as the park facilities are developed, school students and members of the public will be able to walk the bush paths through the regenerating bush.
