armata). An arboretum on Tomingley Road holds a range of Australian native plants. The 17 lots are surrounded by a largely cleared and agricultural landscape. In some cases, road reserves and other linking corridors of uncleared vegetation remain between the woodland islands. Some neighbouring landowners have revegetated areas of previously cleared private land to form additional corridors between these remnants. For certain animals, movement between blocks is necessary on a daily, seasonal or intermittent basis, to provide access to food, shelter, breeding sites and partners. Threatened fauna receive extra protection within the Barna Mia animal sanctuary, which is open to visitors by appointment for nocturnal tours on alternate evenings. Native marsupial fauna include the woylie (Bettongia penicillata), bilby (Macrotis lagotis), mala (Lagorchestes hirsutus), boodie (Bettongia lesueur), and marl (western barred bandicoot: Perameles bougainville). The quenda (southern brown bandicoot: Isoodon obesulus) is locally extinct but may be reintroduced. The woodland's position on the transition zone between the wheatbelt and the jarrah forest determines amphibian populations, with several species existing at the eastern or western limits of their range. Herpetofauna includes the western marsh frog (golden flecked burrowing frog, Heleioporus barycragus), which is generally restricted to the western Darling Range. There are at least 98 species of bird in the woodland, including the almost flightless malleefowl (Leipoa ocellata). Climatically, Dryandra is described as semi-arid, with a warm, dry, Mediterranean climate. It has seven to eight dry months each year with an annual average rainfall of about 500 millimetres (20 in). Seasonal changes in temperature, rainfall and wind direction are marked and more extreme than coastal areas of the south-west. Role in fauna and flora protection The following fauna are known to be living in the woodland and have a conservation status of "threatened" as recorded in the IUCN Red List: Major populations of three nationally endangered species exist in the woodlands: the woylie, the red tailed phascogale, and over 50 percent of the total known population of numbat. After measures aimed at excluding feral cats, the population of numbats in the Dryandra Woodland had increased to 35 by November 2020, after recording just 10 in 2019 and 5 in 2018. There had not been so many numbats recorded since 36 were recorded in the 1990s. Over 800 native flora have been identified within the Dryandra Woodland, including 15 that have been declared priority species under the Department of Environment and Conservation's Declared
