Coastal Plains : Land Use And The Environment, P R. George

Journal of the Department of Agriculture, Western Australia, Series 4

Five years ago, this Journal of Agriculture reported on ways to overcome severe algal pollution of the Peel-Harvey estuarine system, 70 km south of Perth.

Several articles in this Journal of Agriculture discuss improved agricultural practices on the Swan Coastal Plain in particular, although the principals will apply to similar eutrophication of the Slbany harbours, Wilson Inlet and the Vassee-Wonnerup Estuary. They also emphasixe the fine balance between man's demand for potable water and land for rural, industrial and urban use.

Catchment Salinity : Report On A Study Of The East Perenjori Catchment, C J. Henschke

Resource management technical reports

Dryland secondary salinisation has debilitated large areas of land in Western Australia due to clearing of native vegetation for agricultural development. The initial aim of the project (which is the subject of Part I of this report) was to establish a landscape framework for hydrogeological examination of the salinity problem. A catchment of 139 km2, located 30 km east of Perenjori townsite was selected for detailed study. It was mapped for soils, vegetation, topography, landform and salinity using both old and recent aerial photography. A field survey of soil hydraulic conductivity was undertaken to help define recharge areas. Soil-vegetation associations …
