The Alberta–British Columbia foothills forests are a temperate coniferous forests ecoregion of Canada. This ecoregion borders Canada's taiga and contains a mix of subarctic forest and temperate forest species as a result. This makes the region an ecotone region, or a region that acts as a buffer between two other biomes.

Setting

This ecoregion covers two separate areas: the rolling foothills of the Rocky Mountains of Alberta and further west a smaller area of the hills and valleys of central British Columbia. The Clear Hills in the north of the region are steeper.[2]

Average annual temperature vary from -0.5°C to 2°C, with the summer temperatures around 14°C dropping in winter to -17.5°C in the north and -10°C in the south.

Flora

The forests are a mixture dominated by lodgepole pine (Pinus contorta), jack pine (Pinus banksiana), trembling aspen (Populus tremuloides), black spruce (Picea mariana), and white spruce (Picea glauca). Other trees include balsam poplar (populus balsamifera), paper birch (Betula papyrifera) and balsam fir (Abies balsamifera).

Fauna

These foothills are home to the largest populations of moose (Alces alces) in North America. Other mammals include snowshoe hare (Lepus americanus), beaver (Castor canadensis), muskrat (Ondatra zibethica), wolf (Canis lupus) and two subspecies of black bear the cinnamon bear (Ursus americanus cinnamomum) of the Rocky Mountains and the eastern black bear (Ursus americanus americanus) of the Canadian Taiga.

Birds of the area include sandhill cranes (Grus canadensis), ruffed grouse (Bonasa umbellus), spruce grouse (Falcipennis canadensis) and large numbers of waterbirds and New World warblers (Parulidae).

Threats and preservation

These forests have been extensively altered by human activity, especially clearance for planting.

gollark: Not really? If I could somehow make people not want it and skip any of the ethical issues related to that it'd be nice? But they do, and the system satisfies those values.

gollark: People are entirely free to *not* buy a new phone every 6 months and... mostly do... the phone market has been declining because of lengthening upgrade cycles. If people buy unreasonable amounts it's because *they want that*, though possibly because of advertising which is terrible.

gollark: So how do you solve this? Just have someone say "no phones for you if you ask for them too often"?

gollark: It's more efficient in terms of output things per input things.

gollark: You can't reasonably cater to every individual separately, because mass production is more efficient.
