Habitat Fragmentation:  Many species rely on migrations as a means of obtaining crucial resources in areas of more favorable conditions.  Among these species are Bull trout, Gray wolves, and Grizzly bears, which are all currently listed as endangered or threatened species as well.  Fragmentation of valuable habitat and migration routes separate interbreeding populations, form barriers between valuable resources, and threaten the entire existence of many vulnerable species.  Uninterrupted migration corridors must be established and effectively managed to ensure the future welfare of these majestic animals, and in doing so, the future welfare of one of the greatest ecosystems on Earth.
