Vegetation of Doi Tung, Chiang Rai Province, Northern
2007
J. F. Maxwell
The climate of Doi Tung, Chiang Rai Province, is monsoonal with three distinctseasons, viz. cool-dry, hot-dry, and rainy. The elevation ranges from c. 350-1525m and mostof the bedrock is limestone and granite. Vegetation below c. 1000m is mostly deciduous,while above this it is evergreen. A mixed evergreen + deciduous facies is present on thelimestone peaks (up to 1425m). Forest destruction as well as settlements are widespread,thus creating increasingly severe problems with water resources, soil quality and stability, andbiodiversity. The planting on pine monocultures in deforested areas 20 years ago in uplandgranite areas has resulted in much environmental degradation which requires immediaterectification.
