Low Rainfall Zone
The Low Rainfall Zone (LRZ) is one of three biogeographic zones into which south west Western Australia is divided, the others being the High Rainfall Zone and the Transitional Rainfall Zone. The LRZ is considered marginal to the south west, and extends throughout much of Australia. The Zones were first defined by Stephen Hopper Stephen Donald Hopper AC FLS FTSE (born 18 June 1951) is a Western Australian botanist. He graduated in Biology, specialising in conservation biology and vascular plants. Hopper has written eight books, and has over 200 publications to his n ... in his 1979 paper ''Biogeographical aspects of speciation in the southwest Australian flora''. Initially, they were defined in terms of rainfall, with the LRZ being that part of the South West with annual rainfall of less than 300 millimetres (12 in). As the LRZ was marginal to his study area, Hopper did not give a clear demarcation of the zone, merely stating that it References * , !, Rissa, !, Fu ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Rainfall Zone
The High Rainfall Zone is one of three biogeographic zones into which south west Western Australia is divided, the others being the Transitional Rainfall Zone and the Low Rainfall Zone. The zones were first defined by Stephen Hopper in his 1979 paper ''Biogeographical aspects of speciation in the southwest Australian flora''. Initially they were defined in terms of rainfall, with the High Rainfall Zone being that part of the south west with annual rainfall of more than 800 millimetres (31 in). However, following the publication of John Stanley Beard's phytogeographic regionalisation of Western Australia in 1980, it was recognised that Hopper's zones could be defined as aggregates of Beard's botanic districts. The High Rainfall Zone was subsequently re-defined as equivalent to Beard's "Darling Botanical District", later renamed the "South-west Forest Region". When the Interim Biogeographic Regionalisation for Australia (IBRA) was published in the 1990s, Beard's regionalisat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transitional Rainfall Zone
The Transitional Rainfall Zone (TRZ) is one of three biogeographic zones into which south-west Western Australia is divided, the others being the High Rainfall Zone and the Low Rainfall Zone. The TRZ is recognised as having a much higher diversity of rare and endemic plant species than the other Zones. The Zones were first defined by Stephen Hopper in his 1979 paper ''Biogeographical aspects of speciation in the southwest Australian flora''. Initially, they were defined in terms of rainfall, with the TRZ being that part of the South West with annual rainfall of between 300 and 800 millimetres (12–31 in). However, following the publication of John Stanley Beard's phytogeographic regionalisation of Western Australia in 1980, it was recognised that Hopper's zones could be defined as aggregates of Beard's botanic districts. The Transitional Rainfall Zone was subsequently re-defined as equivalent to Beard's ''Roe'', ''Avon'' and ''Irwin Botanical District''s, later renamed '' ...
