Chaîne de la Grande Colline is a mountain range at the core of the Massif de La Hotte of southwestern Haiti, west of the Macaya range. The highest peak is 2025 meters in elevation, and 3488 hectares of land are above 1000 meters, with two peaks (6 hectares) above 2000 meters. Deforestation is so extensive that little original forest remains except at the highest elevations, almost all above 1800 meters. Nonetheless those forests are among the most spectacular in Haiti, with giant tree ferns and hardwoods, some on nearly flat terrain. The remarkable biodiversity of Grande Colline is just being discovered, including 20 species of frogs (some unique to Grande Colline), 17 species of reptiles, and 19 species of birds. This mountain range is not subject to protection resulting in widespread tree-cutting and land clearing activities.
