Fire is the dominant type of disturbance in boreal North America, but the past 30-plus years have seen a gradual increase in fire frequency and severity as a result of warmer and drier conditions. From the 1960s to the 1990s, the annual area burned increased from an average of 1.4 to 3.1 million hectares per year.
Taiga in its current form is a relatively recent phenomenon, having only existed for the last 12,000 years since the beginning of the Holocene epoch, covering land that had been mammoth steppe or under the Scandinavian Ice Sheet in Eurasia and under the Laurentide Ice Sheet in North America during the Late Pleistocene.
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. There are a variety of processes and species that occur in these areas as well. The Köppen symbols of boreal ecosystems are Dfc, Dwc, Dfd ...
Although less than half of the following birds' North American populations nest in the boreal forests, a major portion of their species is reliant on this habitat. Many of these birds are more often aquatic and woodland generalist than species more dependent on the taiga. Greater white-fronted goose Anser albifrons; Snow goose Chen caerulescens
It is over 1,000 kilometres (620 mi) in width (north to south) separating the arctic tundra region from the various landscapes of southern Canada. The taiga growth (as defined in North America) along the northern flank of the boreal forest creates a transition to the tundra region at the northern tree line.

Reindeer live in the far northern regions of Europe, North America, and Asia.They enjoy colder climates like tundra and boreal forests. We can find them in northern countries, which include:
Portions of Wood Buffalo National Park and Whooping Crane Summer Range, the only nesting area for the critically endangered whooping crane, overlap onto the Taiga Plains from the Boreal Plains. To the west it abuts the foothills of the Boreal Cordillera in British Columbia and southern Yukon, and the Taiga Cordillera further north.
