..............................47 iv Summary The distribution of vegetation in Boorowa Shire strongly relates to soil type, geology, and position in the landscape (ie valley floor or ridge top). Three broad plant communities occur: riparian forests; grassy woodlands and dry forests. Riparian forests of Red Gum or She Oak occur along the rivers and major creeks. Woodland communities, dominated by Blakelys Red Gum and Yellow Box, occur along most creek lines and lower slopes. A Red Stringy-bark – Long Leaved Box forest occurs on sedimentary rocks on the lower slopes in the South-east of the Shire. White Box woodlands with a grassy understorey formerly occupied most of the undulating slopes in the Shire, while a grassland/open woodland occupied much of the broad basin centred on Boroowa. Ridge-lines and upper slopes support dry forest in which Red Stringy-bark is always a dominate species. Eight-five percent of the shire’s native vegetation has been cleared. Most of the remaining large blocks of vegetation are dry forests on rocky ridgelines unsuitable for agriculture. Isolated paddock trees and small patches of less than 2ha (200m x 100m), provide the majority of remaining woodland cover. The vegetation of Boorowa is highly fragmented and dysfunctional. The remaining remnants are under considerable stress from increased salinity, over fertilisation, grazing, herbicide drift and soil compaction. Given the extent of clearance it is not surprising that many threatened plant and animal
