Trends in North American and European regeneration research under the ecosystem management paradigm

Original Paper


Forest management on many ownerships in North America and Europe has shifted toward the ecosystem management paradigm. The associated shift toward multiple management objectives and focus on natural development patterns should also be reflected in regeneration research efforts. As new information needs arise, research questions and approaches should be evaluated whether they are still appropriate. Specifically, spatial and temporal scales of research studies need to be expanded to accommodate complex sets of management objectives and constraints, rather than being focused on optimal tree regeneration. At the same time, silviculturists are asked to utilize natural trends as a guide for management, but most natural disturbance studies have focused on stand structures and not the regeneration processes. Criteria commonly used to describe disturbance regimes need to be modified to better guide regeneration research efforts under the ecosystem management paradigm.


Regeneration Ecosystem management Research approaches Natural disturbance
