Marine Protected Areas
Executive Order 13158 defines marine protected areas (MPAs) as "any area of the marine environment that has been reserved by Federal, State, territorial, tribal, or local laws or regulations to provide lasting protection for part or all of the natural and cultural resources therein." There are many different types of MPAs in U.S. waters.
