How can trees extend the life of my pavement, roofing and other man-made materials?
Trees can extend the life of surface materials simply by shading that material from direct sunlight. As someone stands in the sun too long, he or she becomes...
How do urban trees reduce flooding?
Floods can occur anywhere, but urban areas experience increased frequency and severity of flooding events. This is a result of the high percentage...
How do I know/determine if energy consumption is being reduced by planting trees in my municipality?
Energy consumption is reduced by tree shade and evapotranspiration, lowering temperatures of the air and surfaces. Additionally, trees slow down winds by...
How does reducing stormwater runoff save energy?
Stormwater runoff is a significantly growing source of pollution to our streams and rivers and is a large contributor to local flooding events. In urban...
How does vegetation help reduce noise pollution in urban ecosystems?
Vegetation reduces noise pollution through a phenomenon called sound attenuation, which is the reduction of sound intensity. Normal attenuation of sound...
How does vegetation reduce glare and reflection of light on smooth and light-colored surfaces?
Glare is directly from a primary light source, such as sunlight. Reflection is the bouncing of the primary light source from a reflective surface. Vegetation...
Do trees and other vegetation help reduce urban-water runoff?

Trees for Comfort in Public Places
Cities can be extremely hot during long summer days. Air conditioning is often needed indoors and in cars to offset high temperatures. This heat can...
Urban Forests Role in Heat Reduction
Cities contain numerous hard surfaces (concrete, asphalt, metal, and brick) that absorb large quantities of solar radiation (heat) throughout the day,...
Finding Refuge in the Urban Forest
Urban forests and parks offer a refuge for those who live in urban environments. Many people in cities, especially those in lower income areas, live in hot,...
