Robertson Nature Reserve
Robertson Nature Reserve is situated at 750 metres above sea level, near the edge of the Illawarra Escarpment. Red-brown basaltic soils and 1600 mm of annual average rainfall make this undulating plain well suited to rainforest.
A small area of only 4.5 hectares of original rainforest. The canopy is mostly comprised of warm temperate rainforest trees. The small size and isolated position puts this forest in threat of weeds such as privet.
The population of Possumwood is threatened, as almost all of the Soft Tree Ferns have been stolen for horticulture. The Possumwood has tiny seeds which often germinate on the trunks of the Soft Tree Fern. Many Possumwood trees start life as a hemiepiphyte.
