Ancient range

The Porongurup National Park, a relic of an ancient pre-cambrian mountain range, is estimated to have been formed over 1200 million years ago. Imposing granite domes rise dramatically from plains and feature an outlier of the iconic karri forests. The karri forests are confined to a small area in the southwest corner of Australia which includes Denmark, Pemberton, Manjimup and Walpole. The Porongurup outlier has survived due to favourable soil and moisture conditions; however, as the climate changes these majestic trees may not reach their full growth potential in future generations.

Amongst the giants

Karri trees (Eucalyptus diversicolor) rank in height and stature with Australia’s tallest hardwood trees. While the mountain ash, blue gum, and tingle red, commonly record higher, the karri stands proud amongst them. 

Australian National Heritage Listed Park

The Park, recognised for its natural history, ecological significance and exceptional conservation value, has been set aside to be preserved as a national treasure. The Porongurup National Park was placed on Australia’s Heritage List on 4 August 2009.

Biodiversity hotspot

The unique ecosystem and habitat of the Park and environs are recognised as a biodiversity hotpot with over 700 flora including the rare and endangered Ornduffia calthifolia and fine leaved Apium prostratum subsp, Porongurup Range,  300 macro-fungi, and 15 lichen species.  The Park provides habitat for threatened cockatoos: the endangered short beaked Carnaby,  Calyptorhynchus latirostris, the long beaked Baudin C. baudinii and the vulnerable Forest Red-tailed Black Cockatoo C. banksia nasoo. The granite outcrops create a damp refuge for Gondwanan relict species; Porongurup National Park is nationally recognized for a variety of arachnida, in particular, primitive trapdoor spiders.
