Leeuwin-Naturaliste National Park is a national park in the South West region of Western Australia, 267 km (166 mi) south of Perth.
It is named after the two locations at either end of the park which have lighthouses, Cape Leeuwin and Cape Naturaliste.
It is located in the Augusta-Margaret River and Busselton council areas, and is claimed to have the highest visiting numbers of any national park in Western Australia. The park received 2.33 million visitors through 2008–2009.[2]
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.[3]
It has many features of interest including limestone and granite outcrops like Sugarloaf Rock and Canal Rocks. The coastal area also contains many beaches with well-known surf breaks, such as Supertubes, Yallingup Beach, and Smiths Beach.[4] Other coastal features include coastal cliffs and aeolian dunes. The park has a network of caves, some of which are accessible by the public. There are brackish and freshwater lakes and springs, and the park is crossed by several creeks and rivers, including the Margaret River.[3]
The park either passes through or contains historic sites including the Cape Leeuwin water wheel.
Leeuwin–Naturaliste Ridge
Leeuwin-Naturaliste Ridge runs north and south parallel to the coast from Cape Naturaliste to Cape Leeuwin. The ridge is composed of two landform elements. The Leeuwin-Naturaliste Coast is a discontinuous strip of coastal dune limestone known as the Tamala Limestone Formation, which extends along the western shore. The Tamala Limestone is karstified, with numerous caverns and groundwater systems, including the Jewel Caves and Devil's Lair, which contains the earliest archeological evidence of human habitation in Southwest Australia. The Margaret Plateau extends north–south to the east of the Leeuwin Coast. It is an undulating and dissected plateau, composed of the basement rock on which the Tamala Limestone formed. This basement rock is known as the Leeuwin Complex, a strongly metamorphosed igneous Proterozoic rock made up mostly of granitic and anorthositic gneisses. The Dunsborough Fault forms the eastern boundary of the Leeuwin Complex and Margaret River Plateau, where they adjoin the sedimentary Perth Basin.[5] The ridge's geology and the variations in vegetation are confined to a number of very narrow bands that follow the north–south orientation of the ridge.
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 peppermint tree (Agonis flexuosa) and Banksia shrubland and woodland, and significant stands of tall karri (Eucalyptus diversicolor) and jarrah (Eucalyptus marginata) forest.[3]
The national park was created from crown lands along the Leeuwin-Naturaliste Ridge at a time after the main primary industries in the region had been dairying and forestry, and when increased land-use conflict 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.[6]
