The local ecosystem studied was a mountain, rainforest called Mt Keira. This is then divided into two other ecosystem called Hawkesbury Sandstone Open Forest and Narabeen Shale Rainforest. The Hawkesbury sandstone weathers to form a soil that erodes easily, nutrient poor and poor in water holding capacity. The features this ecosystem possesses produces a unique vegetation and animal arrangement. The vegetation in this area are likely to have undersized, tough (sclerophyll) leaves and vivid, often large, prominent flowers. In this report, it concentrated on the Narabeen Shale Rainforest. The Narabeen Shale Rainforest is part of the sub tropical rainforest of Mt Keira. It is concentrated with high stretch boles of sub tropical Red Cedar, Illawarra Flame Tree, Giant Stinging Tree and Strangler Fig that compete for sunlight with warm moderate genus of Coachwood, Lilly Pilly and Sassafrass to take shape a closed canopy.
