Biodiversity.The purpose of this Park is to protect a representative sample of the Mountain Jungle or Yunga, and to preserve an important river basin which supplies water to the agricultural areas and populations nearby.
Mountains.The Park has a great difference in height due to is location on the mountain slope. This causes a great difference in rainfalls: around 800 mm. at the lowest areas, up to 1800 mm. in the high mountain jungles.
The winters are dry and mild, with an average temperature of 17º C. It often snows on the hilltops between june and september. The summers are hot, with maximum temperatures above 40º c. The rain season is fron November to April.
Jungle.This jungle goes from the mountain base, at 450 m. above sea level, to the mountain tops, above 3600 m.high. This difference in height produces great variety in the types of vegetation, which grow in noticeably different communities, although the transition from one to the other is gradual.
