Trees improve water quality! Wondering how trees do this???
Here's how:
Trees reduce stormwater runoff by
capturing and storing rainfall in their canopy
and releasing water into the atmosphere.
Tree roots and leaf litter create soil
conditions that promote the infiltration of
rainwater into the soil.
Trees help slow down and temporarily
store runoff and reduce pollutants by
taking up nutrients and other pollutants
from soils and water through their roots.
