The Mesoamerican Biological Corridor (English acronym MBC; Spanish: Corredor Biológico Mesoamericano, CBM) is a large habitat corridor in Mesoamerica, stretching from Mexico southeastward through most of Central America, connecting several national parks. It was started in 1998 to keep 106 critically endangered species from going extinct. This came from an earlier plan called Paseo Pantera (Panther's Path), originally proposed in the early 1990s.
