We live in a very inter-connected world. This is something that conservationists have learned when studying the species that they are trying to protect; It’s not good enough to create protected habitats that are isolated, like islands surrounded by roads, fences, farmlands, cities, etc. That’s not how most species have evolved. Their habitats need to be connected to others via wildlife corridors if life there is to really thrive and be robust enough to survive in the long-term. Here’s a few reason why these corridors are so important:
1. Some species need to travel long distances to survive
Some species, such as wolves, grizzly bears, elks, cougars, lynx, etc, need to travel long distances to survive. Sometimes protected habitat areas are large enough to provide the needed space, but often they are too small, and without safe corridors to move around, the animals are exposed to all kinds of dangers. The corridors provide a kind of safety valve for protected habitats that are too small, allowing especially the large carnivores to find ways to roam to their heart’s content between different ‘islands’ without being exposed to potentially fatal dangers.
