A review of Canadian forest vegetation management research and practice

摘要

Research and practice in Canadian forest vegetation management was reviewed for the period 1990 to present. Results indicate continued evolution toward a more integrated and ecologically sound program with appropriate focus on key competitors and crop species. Increasing collaboration between academia, government and industry has resulted in >666 new scientific publications, substantially augmenting the existing knowledge base. The development of (Chondrostereum purpureum) as the first biocontrol agent in Canadian forest vegetation management and the use of nutrient-loaded seedlings to enhance establishment success are considered key research highlights. Recent trends in operational practice include a move toward more intensive management on higher quality sites and adoption of innovative approaches (e.g. nutrient loaded seedlings, larger planting stock) and advanced technologies (e.g. electronic guidance in aerial herbicide applications). The lack of long-term growth response data and economic analyses demonstrating positive cost/benefits remain as shortcomings, however continued development of the program will undoubtedly enhance sustainable wood supply and minimize impact on the forest environment.
