Anembo Reserve is a large reserve direct adjacency to Ku-ring-gai Chase National Park that covers approximately 22 hectares, containing important habitat for a range of threatened and non-threatened native species. Including one flora and four threatened fauna species identified within the reserve. Internal land uses include a horse riding exercise arena, a picnic area including BBQ seating and play ground facilities. The plan also addresses a proportion of land surrounded by the reserve, reserved for the Bush Fire Brigade.
The Duffys Forest Residents Association(DFRA) aimed to give the horse arena that was unmaintained, contaminated and had blackend sand a major upgrade. This would include putting down a new crushed sand stone base, new sand, stone boundry and a perimiter fence. However, this was a very expensive job and required lots of funding. There was a big funding drive and finally after many generous donations, the DFRA finally had enough to start the project.
Construction continued and through more donations from State Government level, through Mr Rob Stokes, Member for Pittwater aswell as allocation of Community Building Partnership Grants DFRA was able to be finished. Members of the community who donated towards this project were recognised by having their name on a sign at the entrance to the arena. Anembo Reserve reopened in 2011.
