Historically a wildlife corridor has existed between the northern reserve (Cleveland National Forest) and the southern reserve (Laguna Greenbelt). A wildlife corridor creates areas of natural open space for wildlife migration between natural habitats thereby promoting proliferation of indigenous wildlife species and re-colonization of habitats. Corridors may also help facilitate the re-establishment of populations that have been reduced or eliminated due to random events i.e. fires or disease. This will moderate some of the worst effects of habitat fragmentation. Essentially a wildlife corridor is way of assuring the long-term health and vitality of our open spaces systems. Without it the long-term survival of animal species is in question.
