accedens). Other eucalypts in these eastern areas include York gum (Eucalyptus loxophleba). The upland areas are particularly rich in plant life, while the drier inland plateau is less so. The wetter valleys with fertile soils contain flooded gum (Eucalyptus rudis), bullich (Eucalyptus megacarpa) and blackbutt (Eucalyptus patens). Heath is a common understorey of the jarrah forest in the north and east. The smaller trees commonly found in Jarrah Forest include bull banksia (Banksia grandis), sheoak (Allocasuarina fraseriana), snottygobble (Persoonia longifolia) and woody pear (Xylomelum occidentale). Rare plants within Jarrah Forest include orchid species Drakaea confluens and Caladenia bryceana, and Baumea reed beds are unique to the forest and adjacent areas. Fauna Jarrah Forest supports 29 mammal, 150 bird, and 45 reptile species. Mammals include the numbat (Myrmecobius fasciatus), Gilbert's potoroo (Potorous gilbertii), western quoll or chuditch (Dasyurus geoffroii), woylie (Bettongia penicillata), tammar wallaby (Notamacropus eugenii), western ringtail possum (Pseudocheirus occidentalis), common brushtail possum (Trichosurus vulpecula), quenda or western brown bandicoot (Isoodon fusciventer), and red-tailed phascogale (Phascogale calura). Most of these were once widespread vertebrate species but are now limited to the fragmented portions of Jarrah Forest. The chuditch, before the introduction of large mammalian pest species, was the largest carnivorous marsupial in south-west Western Australia, distributed across 70% of mainland Australia. It now inhabits only 2% and is listed as 'Vulnerable' under the Environmental Protection and Biodiversity Conservation Act of 1999. For species such as the brushtail possum, population decline has not been extensive as they will colonise older restored minesites. Carnaby's black cockatoo (Zenda latirostris) is endemic to south-west Western Australia and is listed as endangered under the EPBC of 1999. Other birds to inhabit Jarrah Forest include rare birds such as the forest red-tailed black cockatoo (Calyptorhynchus banksii naso), Muir's corella (Cacatua pastinator pastinator), black-throated whipbird (Psophodes nigrogularis), western bristlebird (Dasyornis longirostris), noisy scrub-bird (Atrichornis clamosus) and Baudin's black cockatoo (Calyptorhynchus baudinii). Reptiles inhabiting Jarrah Forest include legless lizards, dragon lizards, skinks, blind snakes, pythons and venomous snakes. The western bearded dragon (Pogona minor) was found in restored forest rather than old growth forest. Amphibians found in the northern sector of Jarrah Forest include the rare white-bellied frog (Geocrinia alba), yellow-bellied frog (Geocrinia vitellina) and sunset frog (Spicospina flammocaerulea). Endemic frogs inhabit the southern sector of Jarrah Forest such as the small western froglet (Crinia subinsignifera) and the western marsh frog (Heleioporus barycragus).
