In Costa Rica, land management plans are a tool that local governments can use to generate regulations that complement protected areas and ecological corridors. These three  elements are complementary and must be developed in an integrated fashion to achieve a systematic approach to planning. Management plans implement ecological corridors through tools such as the establishment of specific areas for focal species; the preservation of agricultural areas that function as biological, conservation and sustainable tourism corridors; the creation of buffer zones; and the zoning of aquifer recharge zones for the protection of water resources. Through the University of Costa Rica’s Sustainable Urban Development Research Program (UCR-ProDUS in Spanish), land management plans for more than a dozen municipalities have been developed, including the protected areas Corcovado National Park, Piedras Blancas National Park, Ballena Marine National Park, Juan Castro Blanco Water National Park and Carara National Park.
