Detailed explanation-1: -Trees and woody vegetation do good things for agricultural land. They reduce soil erosion and provide habitat for pollinators. When planted along waterways as riparian buffers, they reduce run-off of nutrients and soil sediment in-stream.
Detailed explanation-2: -Trees reduce the effect of erosive forces using their root systems and foliage. Trees have thick root systems that branch into fine filaments and create a network. This network of root systems help stabilize the soil around the tree and hold it in place.
Detailed explanation-3: -Trees prevent soil erosion. The roots of trees hold the soil tight and prevents washing away of the soil.
Detailed explanation-4: -Trees hold the soil firmly. The canopy of the trees protects the soil from heavy rainfall. The leaf litter that protects the soil from erosion, is also lost during logging. Mining activities also disturb the land and leave the soil more prone to erosion.
