Forest Management

Spruce forests in British Columbia

Canada is the leading country for sustainable forest management with a sciences-based approach to ensure proper and sustainable management of Canadian ecosystems.[7] Almost 90% of the Canadian forests are publicly owned and controlled by their provinces and territories. Each provincial and territorial government allot early levels of harvest and require regenerative practices upon completion of harvesting[2] Additionally, for companies to harvest public lands they must produce a unique forest management plan and consult the public. 6% of Canadian forests are privately owned and must comply with provincial and federal laws and legislations.[2] 2% of the forests are federally owned and the remaining 2% are owned by Indigenous Peoples.

The governments are assisted by the National Advisory Board on Forest Research, established in 1997 and focusing on strategic issues, and the Forest Sector Advisory Council, which represents the interests of the multitude of private, non-profit and academic stakeholders in Canadian forestry. The Canadian Council of Forest Ministers, composed of 14 ministers representing the federal government and the various provinces and territories, is the main tool for dissemination of national and international policy throughout the country.[4]

History of forestry

European forestry in Canada is thought to date back to the 11th century, when Leif Erikson first landed off the coast of what is believed to be Newfoundland.[8] Large scale forestry did not begin until European settlers landed several centuries later. The area that is now Canada experienced significant deforestation during the 18th and 19th centuries, as a booming population of settlers cleared the land; this pattern was also seen elsewhere in North America. Changes in management strategies in the 20th and 21st centuries have been able to halt the trend toward deforestation.[5]

Forestry today

Forestry is a major industry in Canada, contributing over $24.6 billion in GDP to the economy in 2017.

pulp for paper, 9 percent of the industrial roundwood, 4 percent of the wood-based panels and 3 percent of the paper and paperboard.[11] In 2010, Canada enjoyed a significant surplus in their balance of trade, mainly due to being the second-largest exporter of forestry products globally.[10] Much of this is exported, with Canada exporting 20 percent of the world's sawnwood, 18 percent of the pulp for paper, 8 percent of the paper and paperboard, 5 percent of the industrial roundwood and 5 percent of the wood-based panels.[12]

Environmental concerns

Canada's ecosystems depend on large forested areas.

Canadian boreal forest have experienced a 1.5 °C increase since.[14] There is even evidence that some regional areas within the western boreal forest in British Columbia have increased by 2 °C since 1948, and there is a high likelihood that these regions rise by another 3 or 4 degrees by the end of the century, thus permanently changing this ecosystem.[15] Climate change is negatively impacting the productivity of Canadian forests.[16]

Canada is a participant in several international protocols and conferences in areas that affect its forested land. As a signatory to the

biological diversity is a major priority. The latter was the subject of the country's first Conference of the Parties to the Convention on Biological Diversity report.[4]

Natural disturbances

The effects of the mountain pine beetle in Yoho National Park, British Columbia, Canada

In 2016, 15,489,117 hectares (38,274,440 acres) of Canadian forests were destroyed by insects.

prescribed burning and pest reduction techniques have been used to attempt to contain the beetle, large stands of dead trees remain, posing a significant threat of wildfire.[18] Annually, Canada sees around 8,000 wildfires, burning a total of 3,371,833 hectares (8,331,980 acres) in 2017.[2] Over half of these are caused by humans, but nature-caused fires (generally started by lightning strikes) cover over 80 percent of the total burn area, as they are often in remote areas of the country.[19]

The emerald ash borer is another major concern to Canadian forests responsible for the rapid decay of forests in Manitoba, Ontario, Québec, New Brunswick, and Nova Scotia.[20] The emerald ash borer was introduced into North America from Eastern Asia in the 1990s[21] It is estimated that the beetle has caused $1.422 billion in damages since the introduction to Canada.[22] In response, Canada has responded by creating laws and regulations to reduce human-facilitated transport of the beetle. Additionally, the CFIA has cut down thousands of trees to create a buffer zone to halt the progression of the emerald ash borer.[22]

Assisted migration

Main article: Assisted migration of forests in North America

Assisted migration is the act of moving plants or animals to a different habitat. In Canada, this is described as a climate change adaptation program proposal, most often discussed in the context of the relocalization of trees and forests. Indeed, as the Canadian climate gets warmer, tree species' become less adapted to the conditions of their historical southern or downhill range and more adapted to the climatic condition of areas north or uphill of their historical range.[23]

In the late 2000s and early 2010s, the Canadian provinces of Alberta and British Columbia modified their tree reseeding guidelines to account for the northward and uphill movement of forests' optimal ranges.[23] British Columbia even gave the green light for the relocation of a single species, the Western Larch, 1000 km northward.[24]
