THE BIOLOGICAL SURVEY OF THE EASTERN GOLDFIELDS OF WESTERN AUSTRALIA: VEGETATION AND FLORA

WA Museum Records and Supplements | Updated 1 decade ago

Introduction: The structural ·formations have been described and mapped at a scale of 1 : 250 000 (Beard 1969: 1972). During the present survey 198 sites were sampled using the plotless releve technique. This technique, the selection of sites and the parameters recorded, are detailed by the Biological Surveys Committee (1984). The' sites are broadly classified on vegetation structure and plant species composition of the upper stratum into 51 types, including four vegetation complexes (Breakaway, Banded Ironstone Formation, Granite and Greenstone). Vegetation complexes displayed marked changes in vegetation structure and species composition as a result of large changes in thickness of soil over distances of less than a metre. A typical site for each vegetation type is described in Appendix I, together with relevant data on geology, landforms and soils. Vegetation descriptions follow a slightly modified Muir (1977) format. Strata with less than 2% canopy cover are not listed in his format but are listed in this report.
