The Sierra de Bahoruco is in the rest of the province (south, center and west); the part of the Sierra de Bahoruco that is in the province of Barahona is called "Bahoruco Oriental" (Eastern Bahoruco) because it is different from the rest of the mountain range. While pines are common in the Sierra de Bahoruco, they are not common in Eastern Bahoruco where there are rainforests because those mountains, and the province, have the Caribbean Sea to the east and winds bring a lot of water that falls on the mountains.
