Why Trees?

Trees have a powerful impact on air quality, climate change, energy conservation, water quality, economy, comfort, habitat, and public health.

Water Quality

Trees help us clean our water.

By holding rainfall on the leaves and branches, trees make the threats of flooding less likely. The tree roots hold soil in place so that it is not washed away in severe storms.

Water is cleaned as it passes through the roots and into the groundwater. We can save water on irrigation when there is a tree shading the lawns that we water.

  • 100 mature trees catch about 250,000 gallons of rainwater per year
  • Decrease polluted runoff
  • Decrease soil and hill erosion
