            What is a habitat

            corridor?


            A habitat corridor is a strip of green land providing a
            connection between two fragmented patches of habitat. All
            too often, development of land means an animal habitat is
            split apart. This can be detrimental as large structures and

            road networks make it difficult and sometimes dangerous
            to move between habitats. Sometimes animals become
            isolated in their respective fragments and over time this
            can lead to a loss of genetic diversity. In extreme cases a
            population may be susceptible to inbreeding or be wiped
            out entirely by one disease. There is much work going on
            to ensure animals have habitat corridors, including creating                                 In Banff  National Park, Canada,
