Effects of Climate Change on the Boreal Forests in Canada

The main breeding ground of most of the mainland duck is the hole in the north prairie. Drought and high temperature due to the increase in global warming may deplete the northern forest breeding ground caused by the melting of underground permafrost. For example, the total area of ​​Alaska Pond has decreased by about 31% since the 1950s, and the number of ponds has also decreased by about 50% (Randerson, 1130). Climate change in the Canada boreal forest can also change the habitability of habitat by changing the distribution of plants and trees caused by global warming.

Climate: North forests play a major role in mitigating the effects of climate change. Because it stores about twice the carbon of the tropical forest, it can suppress the increase of carbon dioxide in the atmosphere. Only Canada's boreal forest stores an amount equivalent to world fossil fuel emissions over 20 years. Water: Despite the shortage of clean freshwater in most parts of the world, North American boreal forests have millions of natural and unspoiled lakes and rivers, both large and small. In fact, North America is the source of freshwater from the world's largest unfrozen water.

Climate change: Forest loss is both a cause and result of our climate change. Climate change can damage forests such as increased fire in dry rainforests and boreal forests. Within the forest, biodiversity has already been destroyed by climate change and this threat may increase.

According to the Canada Ministry of the Environment's 2011 Annual Report there is evidence that some areas of western forest Canada have increased by 2 ° C since 1948. The speed of climate change causes drought in boreal forests, which leads to the follow-up problem as a whole. This has led the forestry industry to face the challenge of sustainably managing and protecting trees in the northern forest. Climate change directly affects the productivity of boreal forests, and health and regeneration. Due to the sudden climate change, trees are moving to higher latitudes and higher altitudes (north), but depending on species some habitats can not follow climate habitats. In addition, trees in the southern range of the range may start experiencing a decline in growth. Dried conditions also bring about a shift from conifer to poplar in areas more prone to fire and drought

Global warming: Mature forests store carbon. Only Canada's boreal forest holds 34% of world carbon dioxide emissions, so it plays an important role in climate adjustment. When an area becomes clean, trees and soil release large quantities of stored carbon into the atmosphere. Forest loss accounts for 25% of total carbon emissions. Habitat destruction: Many species rely on intact forests to provide evacuation centers and food. As the region becomes clearer, many wild animals can no longer survive there. Nest-making birds, Pine Marten and Woodland Caribou are particularly vulnerable to cuts. As animals are obliged to compete for resources in increasingly small wilderness areas, the significant decrease in wildlife decreases
