In an effort to conserve critical natural and cultural marine resources, the US Departments of Interior and Commerce are partnering with federal, state and territorial agencies to form a National System of Marine Protected Areas (MPA).
225 existing MPAs managed by various agencies will initially enter the system, which aims to enhance protection of marine resources, build partnerships to address issues affecting MPAs, and improve public access to scientific information and decision-making about marine resources. The national system does not bring state, territorial or local sites under federal authority, nor does it restrict or change the management of any MPA.
While MPAs have been established throughout the US for decades, there has not been an overarching mechanism to coordinate effective ecosystem management. About 100 federal, state, territory and tribal agencies manage the nearly 2,000 MPAs across the country, often with no coordinated strategy.
MPAs are areas where natural or cultural resources are given greater protection than in the surrounding waters. In the US, these areas may span a range of habitats including the open ocean, coastal areas, inter-tidal zones, estuaries and the Great Lakes.
The value of MPAs as a tool for protecting biodiversity and restoring fish populations within ecosystems is well documented. Many sites included in the charter group have been the subject of scientific studies comparing commercially and recreationally important fish populations both inside and outside the boundaries of the MPA. In the Tortugas North Ecological Reserve in the Florida Keys, studies on the number of fish populations were conducted before and after establishment of the reserve. Scientists found that three species of commercially important fishes increased in abundance and size within three years inside the reserve.
“MPAs are a critical tool for conserving cultural resources, marine species, habitats and ecosystems, and a national system will make this tool even more effective,” said Will Shafroth, acting deputy assistant secretary of interior for fish, wildlife and parks. “The diversity of sites accepted into the national system help ensure that it is truly a representative system. This is a major step in the nation’s marine conservation efforts, and demonstrates our willingness and ability to work together to conserve our common marine heritage for future generations.”
