When we hear the term “ecological corridors” we tend to think of the natural pathways that land animals like elk or elephants use to move among larger natural areas to eat, drink, mate and meet other survival needs. Corridors are equally important for marine life like whales, turtles, fish, and seabirds, which depend on linkages between ocean areas for daily movement, seasonal migration, and completing their life cycles. Until recently, collaborative research and guidance on marine ecological connectivity had been lacking, but now the Center for Large Landscape Conservation is supporting coordination of work by a unique group of experts that is making the issue a top priority.
