Forest Ecosystem Management. A management approach that aims to maintain healthy and resilient forest ecosystems by focusing on a reduction of differences between natural and managed landscapes to ensure long-term maintenance of ecosystem functions and thereby retain the social and economic benefits they provide to society.That is the definition of forest ecosystem management proposed in this book, which provides a summary of key ecological concepts supporting this approach. The book includes a review of major disturbance regimes that shape the natural dynamics of the boreal forest and gives examples from different Canadian boreal regions. Several projects implementing the forest ecosystem management approach are presented to illustrate the challenges created by current forestry practices and the solutions that this new approach can provide. In short, knowledge and understanding of forest dynamics can serve as a guide for forest management. Planning interventions based on natural dynamics can facilitate reconciliation between forest harvesting needs and the interests of other forest users.

Describes the impacts caused by major forest insects (defoliators and bark beetles) and diseases (excluding those caused by fungi) to the timber resources of the Prairie Provinces and Northwest Territories in terms of wood volume losses due to tree mortality and growth reduction for the 1988-92 period. Most impacts were calculated using an automated system based on defoliation or infestation maps produced by geographic information systems and related inventory data. Results are presented for losses due to the following: spruce budworm (Choristoneura fumiferana), jack pine budworm (C. pinus pinus), forest tent caterpillar (Malacosoma disstria), large aspen tortrix (C. conflictana), bruce spanworm (Operophtera bruceata), mountain pine beetle (Dendroctonus ponderosae), spruce beetle (D. rufipennis), Douglas-fir beetle (D. pseudotsugae), Lodgepole pine dwarf mistletoe (Arceuthobium americanum), and wood decay.
