The La Amistad International Park, or in Spanish Parque Internacional La Amistad, formerly the La Amistad National Park, is an Transboundary Protected Area in Latin America, management of which is shared between Costa Rica (Caribbean La Amistad and Pacific La Amistad Conservation Areas) and Panama, following a recommendation by UNESCO after the park's inclusion in the World Heritage Site list.
The park area is equally split between Costa Rica and Panama, as part of the former La Amistad Reserves of the Talamanca mountain range. It covers 401,000 ha of tropical forest and is the largest nature reserve in Central America and together with a 15 km buffer zone it represents a major biodiversity resource at a regional (ca 20% of the regions species diversity) and global level.
This is recognized in its strategic position in the Mesoamerican Biological Corridor and its designation as a UNESCO World Heritage Site. Its cross-frontier position gives it unique potential to improve bioregional planning. The park’s buffer zone includes coffee and beef producers and indigenous subsistence farmers. A consequence of the difficulty of the terrain, the park is relatively unexplored and the only substantial scientific explorations deep into the park have been led by the Natural History Museum London, INBio and the University of Panama in the last 6 years (2003–2008).
In 2006 the UK's Darwin Initiative funded a three year collaborative project led by the Natural History Museum, London, INBio (Costa Rica) and ANAM (Panama). The aim of which was to generate baseline biodiversity information for the park and a map of the biodiversity. This involved a series of seven multi-disciplinary and international expeditions to remote parts of La Amistad during which over 7,500 plant, 17,000 beetle and 380 herpetological collections were made and deposited in the national collections of Costa Rica and Panama. These expeditions also lead to the discovery of 12 plant species, one dung beetle species, fifteen amphibian and three reptile species new to science.
