McKay Reserve is a small tract of remnant urban bushland in Palm Beach, parts of which contain the endangered ecological community (EEC) Pittwater and Wagstaffe Spotted Gum Forest. [1] [2] [3] The reserve lies on a ridge on the Barrenjoey Peninsula and overlooks western Pittwater.
Mapping by the NSW Office of Environment and Heritage in 2013 [4] shows the reserve as also containing Coastal escarpment littoral rainforest, a particular subgroup of the Littoral Rainforest community, which is also an endangered ecological community. [5]
