EFFECTIVE wildlife management needs to be based on the application of sound scientific principles and concepts. Both of these books provide a framework for the application of concepts and principles to wildlife management problems and attempt to bridge the gap between research and its application in management. Conservation of Wildlife Populations, by L. Scott Mills, explains theories, concepts and principles developed in the field of population biology, and their management applications. It encompasses population ecology, demography and population genetics. Wildlife Damage Control, by Jim Hone, identifies and explains the application of principles involved in assessing and controlling damage caused by wildlife.
