Tree Benefits
Healthy Air
Asthma rates in Washington, DC exceed the national average and afflict more than 1 in 14 of our residents, including over 10,000 DC children. The trees of Washington filter 540 tons of harmful, health-threatening pollutants from the air each year.
Cooling Shade
Cities typically average 10 degrees hotter than suburban areas. Trees provide shade and give off water vapor to cool the city in the summer. Homes shaded by trees have 10-30% savings in air conditioning costs compared to homes without shade. The shade trees of DC save us more than $2.6 million in air conditioning costs per year.
Cleaner Water
Trees help rain soak into the ground rather than run off the surface. The decrease in tree cover in Washington, DC between 1973 and 1997 resulted in an increase of storm water runoff of as much as 34 percent. In much of DC, storm water is collected in the same pipes as sewage and overflows untreated into the Anacostia, Rock Creek, and Potomac rivers as often as once a week. Sewer backups also occur in many city basements. Increasing the urban forest canopy throughout the District will significantly reduce polluted runoff and help cleanup our rivers.
Less Crime
Research has shown neighborhoods with trees have less crime than neighborhoods without trees. Residents living in “greener” surroundings actually report lower levels of fear, fewer incivilities, and less violent behavior. Trees are increasingly recognized as part of the solution to reducing crime.
Reduced Stress
Trees provide relief to physical and visual stress. Green views and access to green spaces in cities help and relieve the everyday pressures of crowding and noise. Research shows that kids are better able to concentrate, complete tasks, and follow directions after playing in natural settings.
Livable Communities
Trees add beauty to neighborhoods, create recreational opportunities, and reflect cultural values.
Increased Property Values
In urban areas across the country, homes with trees sell for an average of 10-20% more.
Tourism
700,000 tourists visit DC each year for the annual Cherry Blossom Festival.
Wildlife Habitat
Trees provide food and shelter for birds and small animals.
Trees and Commerce
Consumers are willing to spend 12% more in stores with trees in front of them than without.
Job Opportunities
Natural resource management job opportunities are growing in cities. Examples include: tree inventory, inspection and care, landscape maintenance, and environmental impact field work and planning.
