Consciously or not, wildlife managers generally act from a theoretical basis, although they may not be fully versed in the details or ramifications of that theory. In practice, the predictions of the practitioners sometimes prove more accurate than those of the theoreticians. Practitioners and theoreticians need to work together, but this proves di

Although Bissonette (Utah Cooperative Fish and Wildlife Research Unit, Utah State U., U.S.) and Storch (Weihenstephan Center of Life Sciences, Technische U. Munchen, Germany) state that a cohesive theory of landscape ecology is not yet possible, they present 17 papers they see as providing elements of theoretical framework, specifically as related to problems of resource management practice. Separate sections address linkages between conceptual and quantitative issues, between people and the landscape, and between theory and management in the field.

The loss and fragmentation of natural habitats is one of the major issues in wildlife management and conservation. Habitat "corridors" are sometimes proposed as an important element within a conservation strategy. Examples are given of corridors both as pathways and as habitats in their own right. Includes detailed reviews of principles relevant to the design and management of corridors, their place in regional approaches to conservation planning, and recommendations for research and management.
