Yatteyattah Nature Reserve is a protected area of only 35 hectares, situated near Milton in the south coast region of New South Wales, Australia.
The monzonite based soils, moderate climate and 1200 mm of annual rainfall produce a high quality Forest Red Gum forest on the higher plateau. The rainforest is of scientific interest as the most southerly sub tropical rainforest remnant in Australia.
Significant tree species include Red Cedar, Myrtle Ebony, Deciduous Fig, Citronella, Silver Quandong, Whalebone Tree and Bollygum, many of which are near their southernmost limit of natural distribution. Outstanding also is the display of epiphytic ferns, such as Birds Nest Fern and Elkhorn Fern.
In 1964, a broad swathe was cut through this small forest for electrical power lines, despite the area being surrounded by clear country and declared a protected area.
