Flora and Fauna
The forests of Doi Khun Tan have changed dramatically in the past century due to human disturbance. The forests can be divided into three types, with distinct elevational ranges.

Lowland elevations (325-850 meter). Originally a teak forest, the lowland elevation is composed of a degraded mixed bamboo deciduous forest as deciduous Dipterocarp- oak forest.

Middle elevations (850-1,000 meter). This is a transitional area where the lowland deciduous forest and upland evergreen- pine forest mix to from the mixed evergreen and deciduous forest. Here are only two species of pine trees in Thailand, a two –needle pine (Pinus merkusii) and three-needle pine (P. kersiya) both of which can be found here.

Upland Elevations (1,000-1,373 meter). The forest here is composed mostly of evergreen hardwood trees and a minority of pine (Pinus merkusii) to from an evergreen- pine forest . Much of the forest and watershed on the west side of the national park have been distrubed; however, pristine conditions are found on the east side
