Trees catch rainwater and slow runoff, which cleans the water and reduces the risk of flooding. Trees help prevent erosion along stream banks and allow more water to soak into the ground to replenish groundwater.

• Trees increase property value
• Trees shade our homes and protect against cold during the winter
• Trees filter pollutants out of runoff as water drains through roots and soil
