Although precipitation is not a limiting factor, the ground freezes during the winter months and plant roots are unable to absorb water, so desiccation can be a severe problem in late winter for evergreens. Although the taiga is dominated by coniferous forests, some broadleaf trees also occur, including birch, aspen, willow, and rowan.
It is essential for climate change to be combated with global action, which is what the Kyoto Protocol in 1997 was created to do. Other measures to protect the taiga would be to prohibit unsustainable deforestation, switch to renewable energy, and protect old-growth forests, (they sequester the most carbon dioxide).
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. [1] The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal ...
The winters are snowy and cold, and the summers are cool. The region receives between 1,000 and 1,400 millimeters mean annual precipitation. [2] Mean annual temperature: 4 °C Mean summer temperature range: 11.5 °C to 12 °C Mean winter temperature range: -3.5 °C to -4 °C.
Summers are cool and short in this sub-arctic climate, with mean temperatures ranging from 7 °C in the north to 14 °C in the south. [ 5 ] [ 6 ] Winters are long and very cold in the Mackenzie Delta, with a typical January mean of -26 °C, but are somewhat milder in the southern extent, with a mean January temperature of -15 °C.

Northern Cordillera forests is a taiga ecoregion that extends across the northern interior of British Columbia, southern Yukon, and a small area of the Northwest Territories as defined by the World Wildlife Fund (WWF) categorization system.
The ecoregion is in the zone of discontinuous permafrost and has a subarctic climate, with summer temperatures averaging around 12.5 °C (54.5 °F), and winter temperatures averaging from −18 °C (0 °F) to −24.5 °C (−12.1 °F). Annual average temperatures are between −2.0 °C (28.4 °F) and −6.5 °C (20.3 °F).
The Taiga Cordillera Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a rugged, mountainous terrestrial ecozone of Canada spanning most of northern Yukon and significant portions of the border between the Yukon and the Northwest Territories.
