Figure 2. The relationship between the Biodiversity Guidebook and the Riparian Management Area and Managing Identified Wildlife guidebooks. This conceptual diagram illustrates how the recommended practices in the different guidebooks are designed to ensure that the critical requirements of all species are protected. The practices in the Biodiversity and Riparian Management Area guidebooks act as the coarse filter, protecting most species; the practices in the Managing Identified Wildlife Guidebook act as the fine filter, protecting those species whose habitat requirements are not adequately covered by the coarse filter guidelines.
