Did you know that 41 percent of U.S. marine waters are protected in some way? If you have ever gone fishing in central California, diving in the Florida Keys, or boating in Thunder Bay, you have visited one of these marine protected areas (MPA).
MPAs are areas of the oceans or Great Lakes that are protected for a conservation purpose. In the United States, there are over 1,600 MPAs spanning a range of habitats, including the open ocean, coastal areas, inter-tidal zones, estuaries, and the Great Lakes. Nearly all of these areas allow multiple uses. About one percent of U.S. waters are highly protected in no-take MPAs to protect sensitive species and habitats.
With different federal, state, tribal and local agencies managing the more than 1,600 marine protected areas (MPAs) located all over the U.S., what is going on in each can get a little disjointed and opportunities to coordinate or share lessons learned can be missed. So wouldn't it be nice if there were some system to coordinate planning and management of our nation's MPAs? Guess what? There is!
Managed by the federal government, the national system of MPAs brings work together at the regional and national levels to achieve common objectives for conserving the nation's important natural and cultural resources. The MPAs in the system are still managed independently, but they now have a framework to tie them all together. There are currently 437 members of the national system of MPAs. Over time, the MPA Center will continue to work with existing U.S. MPAs to increase membership in the national system.
One question many people have about marine protected areas (MPAs) is whether or not there are restrictions associated with the use of these areas. The answer is that...it depends. MPAs are established for the conservation of their natural or cultural resources. While there can be restrictions on certain activities in MPAs, nearly all U.S. MPAs allow multiple uses, including fishing. Some areas, such as marine reserves, are a little more restrictive, limiting the catching of fish, collection of shells, or other activities where something may be removed from the area. Marine reserves are sometimes referred to as “no take” MPAs, and occupy about 1 percent of U.S. waters.
Because marine protected areas (MPAs) vary widely, the National MPA Center developed a system to help describe these areas using characteristics that are common to most MPAs. The characteristics include conservation focus, level of protection, permanence of protection, constancy of protection, and ecological scale of protection. The end result is a common vocabulary for MPA managers, something that comes in handy when exchanging ideas and lessons learned or working to identify additional areas that should be protected.
Interested in finding out if there are marine protected areas (MPAs) where you live or have visited? Check out the Marine Protected Areas Inventory. This online tool lets you use an interactive map to view the MPA Inventory sites and associated data, query sites by specific conservation attributes, or to search and view sites by region. Managers can use the Inventory for marine management and conservation planning. In fact, the primary purpose of the Inventory is to maintain baseline information on MPAs to the assist in the development of the National System of MPAs.
The National MPA Center was established in 2000 following Executive Order 13158. The executive order was issued to help protect the significant natural and cultural resources within the marine environment for the benefit of present and future generations. The order directs the Department of Commerce, the Department of the Interior, and other federal agencies to work closely with states, territories, tribes, fishery management councils, and groups with an interest in marine resource conservation to develop a scientifically-based, comprehensive National System of MPAs representing diverse U.S. marine ecosystems.
The MPA Center is located within NOAA's National Ocean Service and is a division of the Office of Ocean and Coastal Resource Management.
The MPA Center uses science to assess the nature of MPAs and how they are used to sustain healthy marine ecosystems. The MPA Center focuses its objectives on enhancing MPA stewardship by strengthening capacity for planning, management, and evaluation.
The California Ocean Uses Atlas Project is one example of a science and stewardship focused project of the MPA Center. The Atlas fills a critical information gap in ocean management by mapping the full range of significant human uses of the ocean in state and federal waters. Data and maps from the California Ocean Uses Atlas workshops are available online.
There are many different types of MPAs including national marine sanctuaries and national estuarine research reserves.
Thunder Bay National Marine Sanctuary, designated as a sanctuary in 2000 to protect the many shipwrecks of the region, is an example of a marine protected area aimed at conserving cultural resources.
Another example of a marine protected area is South Slough National Estuarine Research Reserve. Since the creation of the reserve, management plans have sought to restrict the most intensive commercial uses and restore natural processes, while ensuring that South Slough is available for public recreational use.
The 13 national marine sanctuaries, managed directly by NOS, and the 27 national estuarine research reserves, managed by states in partnership with NOS, are part of the National MPA Center inventory. Additionally, all 13 national marine sanctuaries and five national estuarine research reserves are members of the national system of MPAs.
