Forest fragmentation and forest management: A plea for empirical data

Abstract

Forest fragmentation is one of the most important conservation issues of recent times. Most of what we know about forest fragmentation is based on speculation and untested theory due to a paucity of empirical data. The lack of empirical data can be attributed to (1) the extreme difficulty in conducting good fragmentation studies, and (2) confusion between habitat loss and fragmentation effects. Empirical data from well-designed fragmentation studies is direly needed to validate theoretical predictions stemming from the fragmentation paradigm. Since the best data will come from landscape-scale experiments in managed forests, partnerships and support from researchers and forest managers is critical in this pursuit. Key words: empirical data, forest fragmentation, landscape spatial patterns
