Presents comprehensive coverage of frequency, cover, density, and biomass measurements and considers the special case of measures of vegetation characteristics obtained via remote sensing. Provides a balanced view of conceptual and practical characteristics of measurement procedures. Includes references to numerous case studies and illustrates the differences in estimates of individual measures obtained by various techniques and units. Copyright (C) Muze Inc. 2005.
