Couchy Creek Nature Reserve is part of an important vegetation corridor and contains remnant lowland forests, including old-growth open forest and an endangered ecological community of lowland rainforest. Ten threatened species have been recorded in the reserve including the endangered Davidson’s plum and Crystal Creek walnut.
The reserve lies within the traditional Country of the Minjungbal People and within the area covered by the Tweed Byron Local Aboriginal Land Council. The reserve provides opportunities for low-key, nature-based day use, such as birdwatching. It also provides opportunities for education purposes, for the public to learn about this much-cleared vegetation type.
