The National Arbor Day Foundation recently compiled statistics noting just how important - and cost effective - trees are to a community or business setting:

• "Healthy, mature trees add an average of 10 percent to a property's value."
  - USDA Forest Service
• "Landscaping, especially with trees, can increase property values as much as 20 percent."
  - Management Information Services/ICMA
• "Trees can be a stimulus to economic development, attracting new business and tourism. Commercial retail areas are more attractive to shoppers, apartments rent more quickly, tenants stay longer, and space in a wooded setting is more valuable to sell or rent."
  -The National Arbor Day Foundation
• "Nationally, the 60 million street trees have an average value of $525 per tree."
  -Management Information Services
• "The net cooling effect of a young, healthy tree is equivalent to ten room-size air conditioners operating 20 hours a day."
  -U.S. Department of Agriculture
• "Trees properly placed around buildings can reduce air conditioning needs by 30 percent
  and can save 20-50 percent in energy used for heating."
