Leschenaultia

Leschenaultia Conservation Park near Chidlow in the Perth Hills protects a significant area of native jarrah forest and associated ecosystems on the Darling Plateau. The park is named after the French botanist Jean-Baptiste Leschenault de la Tour, who collected plant specimens in WA during Baudin's 1801 expedition to Australia and described many species new to science. The park provides accessible forest recreation close to Perth's eastern suburbs, with walking trails through jarrah woodland and seasonal wildflowers. The conservation park designation allows management flexibility appropriate to this multiple-use reserve, balancing nature conservation with adjacent water catchment functions.

The park supports forest-dependent fauna of the Darling Range. Western grey kangaroos and brushtail possums are common. Short-beaked echidnas forage in the leaf litter. The forest supports carnaby's black cockatoos and forest red-tailed black cockatoos that feed on marri and banksia seed capsules. Western rosellas, spotted pardalotes, and numerous honeyeater species inhabit the forest. Bobtail skinks and various lizard species are common in clearings. The park contributes to wildlife connectivity along the Darling Scarp.

Jarrah (Eucalyptus marginata) and marri (Corymbia calophylla) forest dominate the park on lateritic soils. Wandoo (Eucalyptus wandoo) occurs in transitional zones. The understorey features zamia palms, various acacias, and a diverse seasonal wildflower flora including orchids, trigger plants, and native peas from August through October. The park may include populations of rare or endemic species characteristic of the Darling Plateau flora.

The park sits on the Darling Plateau — the ancient, deeply weathered surface of the Yilgarn Craton with Archaean granites and gneisses. Lateritic profiles cap ridge crests. The park is within the water catchment zone for Perth's water supply, making the maintenance of forest cover important for catchment function.

Modified Mediterranean climate — higher rainfall than Perth coast (750–850 mm). Winters cool and wet; summers warm and dry. Spring wildflowers are the prime botanical attraction. Fire risk peaks in summer.

Within Whadjuk Noongar country. The forest provided resources for traditional life on the Darling Plateau. European orchardists and timber cutters arrived from the 1870s.

Leschenaultia Conservation Park was established to protect native forest in the Perth Hills water catchment zone. Management balances conservation with adjacent water utility operations.

Forest walks through jarrah woodland, spring wildflowers August–October, birdwatching. Accessible from Chidlow and Mundaring.

Access from Chidlow area. Basic facilities. Nearest services in Mundaring. Best visited August–November.

Phytophthora dieback management and weed control are primary challenges. Water catchment protection is fundamental to the park's management.
