Forest encroachers are one of the parties often blamed for forest destruction. Forest encroachment in small or large groups with high intensity can damage the forest. They do logging to sell the timber. Trees are felled without any thought of the consequences of deforestation.
In addition to collecting forest products, forest encroachers also open the land by cutting and burning forests to be used as a place to grow. After the land is felt unproductive again then they will move to find new land to reopen.
