Urban Tree Canopy Assessment (EPAN09)
Download as PPT, PDF1 like488 views
In the Chesapeake Bay watershed, approximately 100 acres of forest are lost every day to population growth and development. Trees provide many benefits both in wild and urban settings. They help lower energy costs, improve air and water quality, reduce flooding, and protect water sources. Maintaining and expanding tree canopy cover is important for environmental and community benefits.

- 8. Trees in the wild provide benefits.
- 9. Trees in urban / suburban settings provide direct benefits.
- 10. Trees: Lowering heating and cooling energy requirement by providing shade in summer and blocking cold winds in winter; Improve air quality by absorbing pollutants such as nitrogen dioxide, carbon monoxide, ozone, and particulate matter; Reduce summer air and water temperatures by shading concrete, asphalt, and roof surfaces;
- 11. Trees: Protect from flooding caused by stormwater runoff by promoting rain water infiltration into the soil, preventing erosion, and generally slowing down runoff during rain events; Protect sensitive aquatic habitat from rising temperatures by slowing stormwater runoff, shading surface waters, and minimizing the thermal shock associated with summer storms in developed areas; and, Improve drinking water sources by taking up stormwater pollutants such as nitrogen from soil and groundwater and breaking down pollutants such as metals, pesticides, and solvents that could otherwise enter water reservoirs and wells.
