| Effects of transportation corridors on large carnivores in the Bow River Valley, Alberta | |
| 1996 Conference Proceeding | |
The Canadian Rocky Mountains are one of the last places in North America where an assemblage of 7 native large carnivores still exists. Within the Canadian Rockies however, the status of many large carnivores is becoming increasingly threatened by all types of human development, including transportation routes. Our area of focus is between 70-180km west of Calgary, Alberta, where the Bow River Valley is confined by mountainous terrain. The Trans Canada Highway and Canadian Pacific Railway are major transcontinental transportation routes paralleling the Bow River through the Central Canadian Rocky Mountains (Figure 1). The Trans Canada Highway is, for the most part, a 4-lane divided highway with an average daily traffic volume approaching 14,000 vehicles. The Canadian Pacific Railway is the main rail link between the West Coast and Eastern markets and also a high volume route. Within the Bow River Valley there are approximately 212km of roads in addition to the major transportation routes. |
