Land Systems Of The Brockman River Catchments, S. Porritt Jan 1974

Land Systems Of The Brockman River Catchments, S. Porritt

Natural resources published reports

The survey was conducted to gain basic information about the agricultural land use of the Brockman River Catchment. The University of Western Australia Faculty of Agriculture was interested in the area as a compact, agriculturally diverse area close to Perth which was, therefore, suitable for filed studies. The Department of Agriculture, Moora Office was interested in this study as a framework within which to improve its extension services in the area.

Both parties cooperated in investigations of the area by providing data and equipment. Field work was carried out in summer 1973-74 and data compiled by an agricultural science student …

Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie Sep 1973

Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie

Fisheries Research Reports

The Department of Fisheries and Fauna is responsible for the conservation of the native fauna in Western Australia. The main approach to this problem has been the creation of reserves for "The Conservation of Flora and Fauna". These reserves, known as "Wildlife Sanctuaries", are controlled by the Western Australian Wild Life Authority - a Statutory Authority serviced by the Department.

The object of the acquisition programme is to develop a reserve system which will include, as far as possible, a full and permanent cross-section of the State's native floral and faunal assemblages and, at the same time, provide for the …
