Porongurup National Park has one of the richest varieties of plants in Australia with more than 700 native species within the park’s 2,621 hectares. With its diverse wildlife, tall karri and open jarrah forests, and massive granite domes, the park is a haven for birdwatchers, photographers and wildflower enthusiasts who are drawn by the sheer beauty of this place. Porongurup National Park is also significant for a number of invertebrates that have a link to the Gondwanan supercontinent, when Australia was joined to present day Africa, South America and Antarctica, before they broke apart some 150 million years ago. Isolated several times by higher sea levels, most recently around 55 million years ago, the cool mountain gullies within Porongurup National Park serve as a haven for insects, primitive spiders and land snails. Many of the relict species in the Porongurup Range and in neighboring Stirling Range are more closely related to invertebrate species found in mountainous areas of eastern Australia or on other Gondwanan continents such as South Africa, than to the drier, low-lying areas surrounding the range.
