Into the Banff


Banff National Park is Canada's oldest national park, established in 1885, in the Canadian Rockies. The park, located 110-180 kilometres (70-110 mi) west of Calgary in the province of Alberta, encompasses 6,641 square kilometres (2,564 sq mi) of mountainous terrain, with numerous glaciers and ice fields, dense coniferous forest, and alpine landscapes. The Icefields Parkway extends from Lake Louise, connecting to Jasper National Park in the north.

The park has 56 mammal species that have been recorded. Grizzly and Black bears inhabit the forested regions. Cougar, Lynx, Wolverine, weasel, Northern River Otter and wolves are the primary predatory mammals. Elk, Mule Deer, and White-tailed Deer are common in the valleys of the park, including around (and sometimes in) the Banff townsite, while Moose tend to be more elusive, sticking primarily to wetland areas and near streams. In the alpine regions, Mountain Goats, Bighorn Sheep, marmots and pika are widespread. Other mammals such as Beaver, Porcupine, squirrel, chipmunks are the more commonly observed smaller mammals. In 2005, a total of 5 caribou were counted, making this species one of the rarest mammals found in the park.

Due to the harsh winters, the park has few reptiles and amphibians with only one species of toad, three species of frog, one salamander species and two species of snakes that have been identified. At least 280 species of birds can be found in Banff including Bald and Golden Eagles, Red-tailed Hawk, Osprey, Falcon and Merlin, all of which are predatory species. Additionally, commonly seen species such as the Gray Jay, American Three-toed Woodpecker, Mountain Bluebird, Clark's Nutcracker, Mountain Chickadee and pipit are frequently found in the lower elevations. The White-tailed Ptarmigan is a ground bird that is often seen in the alpine zones. Rivers and lakes are frequented by over a hundred different species including loons, herons, and mallards who spend their summers in the park.
