n weathering would result in soils of low or high availability of base cations. The presence or absence of ecological zones (large areas of similar environmental conditions consisting of temperature, moisture, and fertility, which are manifested by characteristic vegetative communities) were modeled as multivariate logistic functions of climatic, topographic, and geologic variables. Accuracy of ecozone models ranged from 69- to 95-percent correct classification of sample plots; accuracy of most models was > 80 percent. The most important model variables were elevation, precipitation amount, and lithologic group. A regional map of ecological zones was developed by using a geographic information system to apply the models to a 30-m digital elevation dataset. Overall map accuracy was refined by adjusting the best probability cut levels of the logistic models based on expert knowledge and familiarity of the authors with known ecological zone boundaries throughout the study area.

Book Description
As the 21st century approaches, the need to put principles of sustainable living and ecosystem management into practice has never been so urgent. Ecosystem Management for Sustainability recognizes this need and shares the experiences of the editor and 54 contributing authors, each leaders in the advancement of ecosystem management and champions of the natural environment. The book uses the Man And Biosphere program as a case example of a wide variety of resource management activities at work. Through the multi-authored contributions to this book, documentation of a comprehensive spectrum of ecosystem management and sustainable development principles is achieved. Ecosystem Management for Sustainability provides a link between theory and practice of these two philosophies.
