Why Tree Planting by Children Trees planted anywhere in the watershed help to improve water quality by slowing down storm water runoff and reducing soil erosion. They also help lessen flooding. In the woods, trees trap and use up excess nutrients. The forest floor is made up of many layers of decaying leaves, twigs and branches. The absence of trees that provide these organic materials to act as a natural sponge is completely absent. Forests are such an efficient infiltration system that they can filter six inches of water or more each hour. Trees s planted along the marshy plots will act as a buffer, retaining as much as 89% of the nitrogen and 80% of the phosphorous that runs off the adjacent land. Vegetation helps to stabilize the stream banks by reducing erosion caused by water, debris and direct rainfall. In addition, falling leaves decompose in the water and provide food for many aquatic insects that, in turn, becomes food for fish. Trees provide shade, food and cover for wildlife and brighten a drab landscape.However on Education, Provide learning opportunities for students and village communities so people will understand how sustainable environmental conservation leads to increased availability of forest products, and helps to reduce dependency behavior on Natural forest resources. The ultimate outcome will be a new generation of people who understand how environmental conservation works to their benefit
