Trees intercept water, store some of it, reduce storm runoff and the possibility of flooding.
Leaves filter the air we breathe by removing dust and pollution. Temperature in the vicinity of trees is cooler in the summer. In the winter, trees insulate the northern sides of homes and buildings against cold winter winds. Studies have shown that hospital patients recover more quickly when their hospital room offered a view of trees. Trees provide direct and indirect economic benefits to property owners, communites and regions.
