In 1985, realizing that widespread development in northwestern Costa Rica was rapidly decimating the forest in which they conducted their research, Janzen and Hallwachs expanded the focus of their work. Janzen and his wife helped to establish the Area de Conservación Guanacaste World Heritage Site (ACG), one of the oldest, largest and most successful habitat restoration projects in the world. They began with the Parque Nacional Santa Rosa, which included 100 square kilometres (25,000 acres) of pasture and relictual neotropical dry forest and 230 square kilometres (57,000 acres) of marine habitat.[9] This eventually became the Área de Conservación Guanacaste, located just south of the Costa Rica-Nicaragua border, between the Pacific Ocean and the Cordillera de Tilaran which integrated four different national parks. Together these house at least 15 different biotopes, viz (mangroves, dry forest and shrubs, ephemeral, rainy season, and permanent streams, fresh water and littoral swamps, evergreen rain- and cloud forests...) and ca. 4% from world's plant, mammals, birds, reptiles, amphibians, fishes and insects diversity, all within an area less than 169,000 hectares (420,000 acres).[25] It is one of the oldest, largest and most successful habitat restoration projects in the world. As of 2019, it consists of 169,000 hectares (420,000 acres).[25] The park exemplifies their beliefs about how a park should be run. It is known as a center of biological research, forest restoration and community outreach.[11]
