INTEGRATED LANDSCAPE ECOLOGY - A WESTERN-AUSTRALIAN PERSPECTIVE

The wheatbelt of Western Australia now has severe nature conservation and agricultural problems resulting from rapid and excessive clearing of native vegetation. The landscape is comprised of a large number of small remnants of native vegetation within an agricultural matrix. Cur rently, different segments of the landscape are managed virtually in i solation, despite the functional interdependence of these elements. Fr agmented management of the landscape means that neither conservation p roblems or agricultural land degradation can be tackled adequately. Si milarly, management of conservation networks is rendered difficult. We suggest that management has to be integrated across the landscape, an d that complementary strategies can be evolved which simultaneously me et the objectives of conservation and production management. Revegetat ion for the reduction of land degradation such as salinisation, waterl ogging or erosion can also benefit nature conservation. Enhancement of existing conservation networks is possible using this strategy, which can be incorporated into the farm planning process. To be successful, integrated landscape planning and management must be carried out by t he local human community, with expert guidance but not interference fr om government agencies. The situation in the Western Australian wheatb elt has relevance in most other parts of the world where conservation and production needs have to be balanced.
