Drag the slider on the poster to fade between a water system with few trees, and one with abundant trees. Then click on the numbers to see the changes that trees make for cities.
Rain refreshes the land and nourishes the green landscape. But as houses, stores, schools, roads and parking lots spread and natural tree cover is lost, so is the absorbing effect of vegetation and soil. The welcome rain becomes costly stormwater runoff. Without the benefit of trees and vegetated infrastructure, waterways are polluted as oils, heavy metal particles and other harmful substances are washed away. Fish and wildlife suffer, drinking water becomes expensive or impossible to reclaim, property values are reduced, and our living environment is degraded.Do you live in a Tree City USA?
