Résumé

Forest research sites database helps to ensure site protection: The Ontario Research Sites (ORS) database houses information on more than 500 forest research trials dating back to 1938. These research trials, primarily from the Province of Ontario, were conducted by scientists from many agencies such as the Canadian Forest Service (CFS), Great Lakes Forestry Centre (GLFC), Ontario Ministry of Natural Resources (OMNR); non-profit agencies and universities. The establishment and management of long-term research trials can be very expensive, therefore, it is important to document and preserve this information so it can be made readily available for future use. The database was created to reduce the management costs associated with paper files, make the data searchable, and to disseminate information as needed in a timely and efficient manner.

Improving understanding of jack pine budworm outbreaks in Ontario: Information that explains the ecological relationship between jack pine budworm and jack pine helps scientists predict the risk of jack pine budworm defoliation, develop new sampling techniques, and ultimately devise management strategies. To advance this understanding, Chris MacQuarrie, a research scientist at Great Lakes Forestry Centre, has initiated a study to examine the combined effects of stand, tree and insect factors on the dynamics of jack pine budworm populations. During the course of this study he has identified a possible link between degree of defoliation and soil characteristics.

On-line decision tool informs homeowners of the costs of treating versus replacing infested ash trees: Many homeowners in Ontario and Quebec are presently facing the reality that their ash trees are being infested and killed by the emerald ash borer. These homeowners can now use an online decision tool when they are trying to decide the fate of these ash trees. The tool (the Canadian Forest Service Ash Protection Model) calulates the costs associated with treating the tree to protect it versus removing and replacing it. Included in the analysis are benefits and costs that homeowners may not have been aware of.

Recovery strategy for Woodland Caribou: Woodland caribou (Rangifer tarandus caribou) is designated as a threatened species under both the 2002 Federal Species at Risk Act and the 2007 Ontario Endangered Species Act. Consequently, managing the species requires a thorough understanding of its habitat preferences and population dynamics. Great Lakes Forestry Centre (GLFC) research scientist Dr. Ian Thompson is contributing to this knowledge with a study on the impacts of human activities on caribou populations. Policy makers use the resulting science to devise policies that will promote sustainable populations of caribou.
