What is an effect of reforestation on watersheds?

Reforestation plays a significant role in enhancing the health of watersheds, particularly through its impact on water cycles and water quality. When trees are planted in an area, they help restore the natural balance of the hydrologic cycle. Trees absorb rainfall through their roots, which can reduce surface runoff and promote the infiltration of water into the soil. This process can lead to a more stable and sustained water supply in streams and rivers.

Additionally, reforestation contributes to improved water quality. As trees grow, they filter pollutants from the water as it moves through the soil, leading to cleaner water entering waterways. The increase in vegetation also helps prevent soil erosion, reducing sedimentation in rivers and lakes, which is crucial for maintaining aquatic habitats.

Overall, the restoration of tree cover through reforestation has multiple positive effects on watershed health, promoting a more balanced ecosystem conducive to both water conservation and improved quality for surrounding environments.
