Which Tool Should I Use?

A brief guide to appropriate uses of i-Tree tools.

Trees remove pollutants from the air.

Poor air quality can lead to health problems, landscape damage, degraded ecosystems, and reduced visibility.

Trees absorb carbon dioxide from the air and store carbon as wood.

Carbon dioxide (CO2) is a greenhouse gas that traps heat in the atmosphere - trees trap the carbon and release the oxygen.

Trees help control storm water.

The leaves on trees intercept rainfall while their roots absorb water from the ground.

Trees provide other benefits as well!

They enhance property values, improve health and well-being, lower summer air temperatures, and provide wildlife habitat.
