The Southern Highlands Shale Forest and Woodland is a mixed grassy woodland and sclerophyll-temperate forest community situated within the Southern Highlands region of New South Wales, Australia. An ecotone featuring clay soils derived from Wianamatta Group, it is listed as an endangered ecological community by the Environment Protection and Biodiversity Conservation Act 1999 as less than 5% of the original extent remains today.[1] Three varieties of the Shale Woodland exist: ‘typical’, ‘tall wet’ and ‘short dry’.[2]
The community is restricted to a small area in the Southern Highlands, on lightly rolling hills and some precipitous slopes on shale, in disjointed and fragmented patches of less than five hectares (12 acres) in area.[3]
It is present within an area bounded by the Illawarra Escarpment in the east, Burrawang and Bundanoon in the south, Canyonleigh and Mittagong in the west and Berrima and Colo Vale in the north, with extended remnants of it reaching Wollongong to the east coast, the Royal National Park in Southern Sydney to the northeast and as well as the Blue Mountains in the northwest. It also occurs in the Wingecarribee local government area. The community is multivariate, as it features tall open eucalyptus forest found in Eastern Australian temperate forests, which grade into dry grassy woodland and scrub, reminiscent of the transition observed in a Forest–savanna mosaic, although it originally existed as woodland. The soils are derived from Wianamatta Shale. Annual precipitation ranges from 1,400 mm (55 in) in the east to 900 mm (35 in) in the west.[4]
The Cecil Hoskins Nature Reserve, Nattai National Park, Morton National Park, Hammock Hill and Old Bowral Airfield council features the community. It is also present between the grassy woodlands and forests of the Southern Tablelands in the west and the Cumberland Plain in the north.[2]
