Types of Corridors
Types of Corridors
There are several types of corridors: migration, range and those necessitated by the threat of climate change.
Migration: A migration corridor is one required by animals that travel the same path on a seasonal migration, usually twice a year, in the spring and in the fall. The Path of the Pronghorn in the United States is a classic migration corridor. assaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Range: A range corridor provides an animal that roams widely with enough room to travel for food and to find new territory. A good example is the wolverine. Wildlife biologists fitted a male wolverine, M-3, with a satellite collar programmed to uplink his location every five minutes and tracked him from his home in Glacier National Park in Montana, north into Waterton Lakes National Park in Alberta, still further into British Columbia, then back to Alberta. His territory turned out to be hundreds of square miles. aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Climate Change: To illustrate the importance of connectivity, and corridors as an adaptation strategy for climate change, take a look at the lynx. The present day range of the lynx is widespread across Canada and Alaska, with a southern tail to its distribution following the Rocky mountains as far south as Colorado. But what might happen to these habitats as the planet warms? Scientists using the most advanced tools available predict the habitat of the lynx will both contract into more isolated pockets and shift north by 2100. These marooned habitats would be too small to sustain lynx populations. In addition, the lynx depends on the snowshoe hare for the vast majority of its food. Modeling shows that there are even fewer places where the lynx and snowshoe hare may be found living together by the end of this century. Both species need large connected and protected areas now so they can adapt to the changes that are coming.
