Beedelup National Park is a national park in Western Australia (Australia), 277 km south of Perth. It is situated on the Vasse Highway some 10 km west of Pemberton. The park is especially lush and damp due to an abundance of water. Gazetted in 1910, the park was declared an A Class Reserve in 1915. The Pemberton National Parks Board has been responsible for management of the park since 1957. Controlled burns occur within the park and some clear felling operations have been conducted in selected areas.
The park is mostly karri forest, with mixed areas of jarrah and marri. The loamy soil supports large colonies of moss and plants such as the swamp peppermint, hibbertia, karri hazel, waterbush, myrtle wattle and lemonscented Darwinia all of which thrive in the damp conditions. Some of the forest is an excellent example of uncut old growth forest. Some of the upland areas are sandy and support communities of heath vegetation. Other plants of interest in the area include Crowea dentata, Crowea augustifolia and Choretrum lateriflorum. Some rare fauna are thought to inhabit the area including the Woylie, Numbat and the Tammar.
