Origin of Water Supply
When it is raining, the tree canopy, including branches and stems, is an obstacle to reduce the velocity of rain contacting the ground. Additionally, the root system which wildly spread around the trunks, will not only assist the penetration and percolation, but also reduce the run off water dropped on the ground as well. At the end of the rainy season, the water retained in the ground will be released and finally gathered together into several creeks. Which one of them in front of you is a part of several creeks are the origin of Mae Jam River which will runs into Ping River, and then, combining with the others to be Chao Pra Ya River which is considered the major blood stream of Thailand

Everlasing Value
An ecosystem is consisted of both living and non-living components. When we talk about trees, people always think about living trees. In fact, standing and lying deaths, are also important to the system. They are not only the home to several species of floras and faunas, but also the sources of nutrients to be returned to the ground. This is how a live cycle exists eternally. Therefore, all of us can be a part of maintaining this precious heritage to be existed forever.
