Trees protect waterways from erosion and lessen the impact of floods and droughts. Trees help water soak into the soil around them. This prevents runoff, soil erosion and flood damage, leading to better aquatic habitats and water quality. Tree roots also filter contaminants and pollutants and their leaves trap windblown dust, keeping them out of waterways. Trees can be planted on sloping land to halt landslides and protect waterways from silt.
