Banff National Park, AB (No. 12)

Since the 19th century, humans have impacted Banff's environment through introduction of non-native species, controls on other species, and development in the Bow Valley, among other human activities. Bison once lived in the valleys of Banff and were hunted by indigenous people, but the last bison were killed off in 1850s. In 2017 a small herd of sixteen plains bison were reintroduced into an eastern section of the park. Elk are not indigenous to Banff, and were introduced in 1917 with 57 elk brought in from Yellowstone National Park. The introduction of elk to Banff, combined with controls on coyote and wolves by Parks Canada beginning in the 1930s, has caused imbalance of the ecosystem. Other species that have been displaced from the Bow Valley include grizzly bears, cougars, lynx, wolverine, otter, and moose. Beginning in 1985, gray wolves were recolonizing areas in the Bow Valley. However, the wolf population has struggled, with 32 wolf deaths along the Trans-Canada Highway between 1987 and 2000, leaving only 31 wolves in the area.

The population of bull trout and other native species of fish in Banff's lakes has also dwindled, with the introduction of non-native species including brook trout, and rainbow trout. Lake trout, westslope cutthroat trout, and chiselmouth are rare native species, while chinook salmon, white sturgeon, Pacific lamprey, and Banff longnose dace are likely extirpated locally. The Banff longnose dace, once only found in Banff, is now an extinct species.

The Trans-Canada Highway, passing through Banff, has been problematic, posing hazards for wildlife due to vehicle traffic and as an impediment to wildlife migration. Grizzly bears are among the species impacted by the highway, which together with other developments in Banff, has caused fragmentation of the landscape. Grizzly bears prefer the montane habitat, which has been most impacted by development. Wildlife crossings, including a series of underpasses, and six wildlife overpasses, have been constructed at a number of points along the Trans-Canada Highway to help alleviate this problem.
