Why Trees Are Important

Trees literally hold our island state together. They help define Hawai‘i’s sense of place, that special connection between our diverse cultures and the environment, the land and its people. While trees in urban areas may appear to have a different function than trees in the natural forest, they often are the first connection that communities have to nature. 

 


Healthy Trees Equal…


Healthy Communities

Each year 100 large, mature street trees help create healthier communities by removing 19 tons of carbon dioxide and 372 pounds of other air pollutants.

Better Business

Tree-lined commercial districts are better for business. People report more frequent and longer shopping and spend up to 12 percent more for goods when they shop in attractive settings.

Healthy People

Tree-filled neighborhoods are safer, reduce mental and physical stress, and encourage people to spend more time outdoors.

Energy Cost Savings

Trees provide shade and cooling, greatly reducing energy costs. Trees save more than $622,000 per year (based on 2013 rates of $.32/kwh for 43,000 inventoried street trees.)

Reef Protection

A healthy urban forest reduces erosion and filters pollutants significantly reducing runoff and the destruction of our valuable reefs.

Watershed Protection

Trees cost-effectively filter and improve water quality by reducing stormwater runoff and flooding. Trees in Honolulu intercept more than 35 mil. gallons of stormwater per year. This contribution is valued at more than $350,000 annually.
