Whicher Range, also known as Whicher Scarp, is a range in the South West region of Western Australia. The range has an average elevation of above sea level.〔(【引用サイトリンク】title= Bonzle Digital Atlas – Map of Whicher Range )〕 Bounded by the Swan Coastal Plain to the West and the South, the Darling Scarp to the North and the Blackwood Plateau to the East, the range is approximately South of Busselton. The range has the form of a crescent shaped scarp. Composed of lateritic Mesozoic sediments the range marks the Southern and Western edge of the Yilgarn Block. ==Ecological fragility== The range is also the location of endemic rare flora 〔''Whicher Range near Busselton supports at least 12 plant species found nowhere else'' Landscope (Como, W.A), Summer 1994/95, p. 35〕 and this had been identified in the 1970s.〔Western Australia. Environmental Protection Authority. Conservation Through Reserves Committee. (1974) ''Descriptions of conservation reserves in Western Australia'' Conservation reserves in Western Australia : report, p1-1 - 1-29〕 It has also been surveyed more recently in 2008, showing that further interest in the range's floristic uniqueness deserved more study.〔Keighery, B. J., Keighery, G. J., Webb, A., and Longman, V. M.(2008) ''A floristic survey of the Whicher Scarp''Perth : Department of Environment & Conservation, Unpublished report.〕 The most critically endangered species that inhabits the Whicher range is ''Petrophile latericola'' also known as Laterite petrophile, Ironstone Petrophile or the Ironstone Pixie Mop which has a range of approximately within the range.〔(【引用サイトリンク】title= Approved Conservation Advice for Petrophile sp. Whicher Range (G.J. Keighery 11790) WA Herbarium (Laterite Petrophile) )〕 Another threatened species that inhabits the range is ''Grevillea elongata'' or the Ironstone grevillea which is found mostly in one single community known as ''Southern Ironstone''; this species is under continuous threat from weeds such as ''Watsonia''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Whicher Range」の詳細全文を読む スポンサード リンク
