Forest Mensuration

Klappentext The new! revised edition of the standard volume on forest measurement The updated edition of this long-standing classic! Forest Mensuration! Fourth Edition! provides new! complete coverage of current measurement practices and technological applications that expand the role of forest mensuration to include monitoring forest resources. This integrated approach takes into account all the resources of a forest! including such nontimber vegetation parameters as regeneration! lesser vegetation! woody detritus! and carbon. Providing solid working knowledge of all concepts and methods! along with guidance for further study! featured material includes: * Applications of personal computers! global positioning! and GIS* Key concepts of tree-stand parameters and principles of measurement* Fundamental concepts of sampling methods* English and metric units Forest Mensuration! Fourth Edition! is a valuable resource for students in forestry and forestry-related studies.
