The term “Marine Protected Area” (MPA) refers to an area of the marine or coastal environment that is afforded some degree of legal protection for natural and/or cultural resources. MPAs have been used effectively both nationally and internationally to conserve biodiversity, manage natural resources, protect endangered species, reduce user conflicts, provide educational and research opportunities, and enhance commercial and recreational fisheries. Numerous MPAs are in effect in Alaska.

MPA is a general term that includes a wide variety of levels of resource protection. Some people think MPAs are the same as marine reserves (no-take areas), but marine reserves are simply one type of MPA. Many MPAs are multiple-use areas where a range of human activities are allowed.


Sitka Pinnacles Marine Reserve

An area known as the Sitka Pinnacles, located off Cape Edgecumbe in the Gulf of Alaska, has been closed to all bottom fishing and anchoring since 1999 to protect lingcod, rockfish, and corals.
