Download the WA South Coast Macro Corridor Network strategy by clicking here A bioregional strategy for nature conservation prepared by the Department of Environment and Conservation (WA) and South Coast NRM. January 2006. Through preparation of Southern Prospects 2004-2009: The South Coast Regional Strategy for NRM, the significance of the regional scale macro corridor concept as an adjunct to the existing and proposed protected area network (primarily national parks and nature reserves) has become more widely apparent as a strategy towards achieving the best long-term outcomes for biodiversity conservation. The potential importance of the proposed monitoring site network has also become more apparent in the face of a suite of threats to biodiversity including the effects of climate change.
