The Cape Range National Park is an area of 50,581 hectares and contains within it spectacular gorges and over 700 known caves. These cool humid caves are home to 54 species of subterranean fauna known as ‘troglobites’, some of which occur nowhere else in the world. Below the cool humid caves lies a vast underground freshwater aquifer that hosts a unique group of underground aquatic animals known as ‘stygofauna’. Over 600 species of flowering plants are found in the area, including the Sturt Desert Pea and the delicate Bird Flower. In 1987 the Ningaloo Reef and surrounding waters were designated as the Ningaloo Marine Park. The Ningaloo Marine Park abuts the Cape Range National Park and encompasses 260 kilometres of coastline. At the closest point the reef is within 100 metres of the shore. The Ningaloo Reef is the closest reef to a land mass in the world. The reef has a vast ecological diversity including more than 250 coral species, 66 different molluscs and 500 species of fish. It provides a rookery for turtles, including the loggerhead and endangered green turtle.
