Ecological and conservation insights from reconstructive studies of temperate old-growth forests

Reconstructive studies that use paleoecological, dendroecological, historical and other approaches in order to interpret long-term ecosystem dynamics are increasingly generating valuable insights for ecologists, conservationists and foresters who are interested in the ecology, protection and management of old-growth forests. In most cases, the historical context provided by these studies reveals a long-term pattern of change that challenges assumptions about the pristine condition of these systems. Ironically, it is the history of environmental fluctuations, natural disturbance processes, and subtle, often indirect, human impacts that is revealed by reconstructive work that may shape the characteristic structure, composition and ecosystem processes of old-growth forests, and that will certainly provide the greatest challenge to their future conservation and management.
