In south Western Australia, the lack of good quality feed in late summer and autumn is a major constraint to livestock production. This feed gap is usually filled by costly supplementary hand feeding of grain or hay. The ability of some trees and shrubs to provide good quality forage during summer and autumn has generated interest for many years (Corbett, 1951; Everist, 1969; Snook, 1987;Oldham et al., 1991, Lefroy, 1991). The dual benefits of reducing the need for supplementary hand feeding and deferring the grazing of annual pastures until they are well established has recently led to the recognition of …

The most serious erosion was found to be occurring in the Donnybrook area due to a combination of erosive winter rainfall, steep slopes and erodible soils. The most serious erosion was found to occur when storm runoff entered the vegetable plots from above, providing a transporting medium for the cultivated soil. A predictive model of erosion showed that soil texture, furrow slope, plot length, rainfall erosivity and canopy cover were significant factors affecting soil loss.
