Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Grid (1 km) of effective and partially effective marine protected areas (MPAs) in coral reef regions of the world. MPAs are gridded with values according to the following definitions: 10) Effective--site is managed sufficiently well that in situ threats are not undermining natural ecosystem function; 20) Partially effective--site is managed such that in situ threats are significantly lower than adjacent non-managed sites, but there may still be some detrimental effects on ecosystem function; 0) Ineffective, unknown, or no management (including areas outside of MPAs). Grid is based on the MPA_poly shapefile and was used to adjust the overfishing and destructive fishing pressure on coral reefs in the Reefs at Risk Revisited model.</SPAN></P></DIV></DIV></DIV>
