Yukon is home to extensive boreal forest that covers an area of approximately 28.1 million hectares (ha) and plays an integral role in the regulation of climate locally, regionally and internationally. Yukon’s forests contribute to the territory’s economy by providing wood and other forest products, local employment, regional development, tourism and recreational opportunities in addition to being valued as a vital cultural, social, historical and educational resource. …Boreal ecosystems are especially vulnerable to climate change. Melting permafrost, increased severity of insect outbreaks and drought are driving major forest changes …Potential exists for rapid ecosystem transitions, with parts of the boreal forest nearing ecological “tipping points” by the end of the century. Scientists are already beginning to see evidence of climate associated declines of spruce, pine and aspen in some parts of the boreal forest.
