One national park, the Corcovado National Park, is internationally renowned among ecologists for its biodiversity (including big cats and tapirs) and is where visitors can expect to see an abundance of wildlife. Corcovado is the one park in Costa Rica where all four Costa Rican monkey species can be found. These include the white-headed capuchin, the mantled howler, the endangered Geoffroy's spider monkey, and the Central American squirrel monkey, found only on the Pacific coast of Costa Rica and a small part of Panama, and considered endangered until 2008, when its status was upgraded to vulnerable. Deforestation, illegal pet-trading, and hunting are the main reasons for its threatened status. Costa Rica is the first tropical country to have stopped and reversed deforestation; it has successfully restored its forestry and developed an ecosystem service to teach biologists and ecologists about its environmental protection measures. The country had a 2018 Forest Landscape Integrity Index mean score of 4.65/10, ranking it 118th globally out of 172 countries.
