Description

The park extends over 100 miles, from Cape Naturaliste in the north to Cape Leeuwin in the south. It is composed of 28 separate reserves, which together have an area of about 15,600 ha. Despite the park's large size, the reserves are fragmented, and in many places the park consists only of a narrow coastal strip.Keighery, Greg & Lyons, Michael & Gibson, N. & Keighery, B.. (2011).

Flora and fauna

The park contains a large range of geologic features and soil types. The landscape and soil diversity supports a range of plant communities. These include coastal herblands and grasslands, sedgelands, and heath near the coast. Further inland are shrublands, woodlands, and forests, including

Conservation

was arising from the spread of wineries, increased population on hobby farms and other agricultural activities. Since then many competing land uses have created a complex land management scenario for state and local government authorities trying to mediate quite conflicting issues. The national park is located on some of the most vulnerable land in the region.

2021 Bushfire

In December 2021, a bushfire was deliberately lit according to police. The fire destroyed almost 5,500 hectares.
