If people and animals living in the foothills of mountain forests feel a lack of water in mountain springs, it is likely that trees are using water indiscriminately due to the drought.
A look at the forests and trees along the Blue Ridge Mountains in the United States reveals that the longer the dry season lasts, the more thirsty trees begin to graze the streams around them. Surprisingly, the higher the trees, the more water they will use, provided that there is a severe shortage of water.
The study was conducted by Katie McCullen, a student at the North Carolina State University Geological Survey Center. Their research has shown that people in mountainous areas need to know that if there are forests in the mountains and the population uses water from high altitudes, then this water may be scarce in drought. There may even be a water shortage.
Research has been done on the Great Smoky Mountain Park, which is part of the Oak Ridge Mountain Range. In this regard, satellite images and data from 1984 to 2020 have been analyzed. These images were based on thermal infrared. In this regard, data of about 15000 square miles of forests were read which covers many US states.
The forests on the hills produce extremely clean and healthy water which is no less than a mineral liquid. This is how precious water is. According to the data, when the drought came, the trees used more water and thus the flow of water was severely affected as this water passes through tens of millions of trees and each tree gets its share of it.
Experts say that by understanding this situation, we can predict the arrival or scarcity of water in the populations, animals and fields at the foot of mountain forests. This forecast can be very helpful, especially during droughts.
