|
Forests that maintain and nurture water sources and regulate river flow. They are designated as conservation forests because they do not allow rainwater to run off all at once, but always store a certain amount, which helps to secure water resources and prevent flooding. They currently cover an area of over 6 million hectares, making them the largest of all conservation forests. These forests can be either artificial or natural, and the tree species are diverse.
