The role of forest ecosystems in water cycles primarily revolves around regulating water quality and supply. Forests play a crucial part in the hydrological cycle through their capacity to intercept precipitation, promote infiltration, and maintain moisture levels in the soil. The foliage of trees captures rainfall, reducing the speed at which it reaches the ground, which helps prevent runoff and encourages water to percolate into the soil. This process recharges groundwater supplies and supports the sustained release of water into streams and rivers, thereby maintaining hydrological balance.

Additionally, trees and vegetation contribute to water quality by filtering pollutants and sediments from water as it moves through the forest floor and root systems. This natural filtration process ensures that water returning to aquatic systems is cleaner and healthier for both ecosystems and human uses.

While regulation of soil erosion and enhancement of biodiversity are important ecological functions within forest ecosystems, they are secondary to the direct regulation of water quality and supply. Urban development, on the other hand, generally has an adverse effect on water cycles, leading to decreased infiltration, increased runoff, and potential degradation of water quality.
