DOWNLOAD EBOOKThe Forest Insect and Disease Survey (FIDS) is responsible for conducting and reporting insect and disease surveys of forests in the Northwest Region, which includes Alberta, Saskatchewan, Manitoba and the Northwest Territories. This report summarizes forest insect and disease conditions and other tree-damaging agents within the Northwest Region for the year, and also describes pest control projects throughout the region. An update of surveys for acid rain symptoms in permanently established Acid Rain National Early Warning System plots is reported, and forecasts of spruce budworm, jack pine budworm, and forest tent caterpillar populations are given.

DOWNLOAD EBOOKThis atlas presents maps of historical defoliation by the eastern and western spruce budworms and historical outbreaks of the mountain and southern pine beetles during the past half century. The maps encompass various regions of the conterminous United States and eastern Canada. This publication also serves as documentation for an extended set of digital maps, which are available on our website. The digital maps are useful for investigating spatial dynamics of insect populations and for providing pest disturbance inputs to spatially explicit forest simulation models.

DOWNLOAD EBOOKForest 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.
