      Biosphere Reserve Information



  General Description   The Biosphere Reserve is situated on the boundaries of two major biogeographic regions: the Cobar Peneplain and the Darling Depression of New South Wales. The topography is gently undulating with red sand dunes supporting old growth mallee in the west and open grassy flats with bimble box (Eucalyptus populnea) in the creek lines, and gentle rises supporting white cypress pines (Callitris spp), wilga (Geijera parviflora), kurrajongs (Brachychiton populneus) and belah (Casuarina cristata) in the east. The Merrimerriwa Range is a dominant feature, which crosses the southeast corner of the Biosphere Reserve. It rises about 200 metres above the surrounding plains and is composed of quartzite, conglomerate and sandstone. The varied geography of the reserve and its location in central New South Wales is reflected in the diverse plant and animal communities. There are at least six species of mallee. The reserve supports a rich variety of fauna including the wallarroo, (Macropus robustus) and insectivorous bats. The three major species of kangaroos in Australia: the eastern grey, (Macropus giganteus), western grey (Macropus fuliginosus) and red kangaroo (Macropus rufus) all occur in the biosphere reserve. Almost 130 bird species have been recorded. Yathong contains a number of Aboriginal sites including open campsites, art sites and scarred trees. These resources are significant in that they represent a regional pattern of changing land use and settlement for over a century. Since the area has been gazetted as a Nature Reserve, human activities have been reduced to the maintenance of access tracks, boundary fences and selected buildings. Tourism (500 visitors annually in 2003) is limited to scientific groups or individuals, or educational groups.
