What is one of the primary functions of wetlands?

One of the primary functions of wetlands is to prevent flooding by absorbing excess water. Wetlands act like natural sponges, soaking up rainwater and releasing it slowly over time. This important role helps to mitigate flood risks in surrounding areas during heavy rainfall or snowmelt. The presence of wetlands can significantly reduce the velocity of floodwaters, allowing them to percolate into the soil and recharge groundwater supplies. Additionally, the water-holding capacity of wetlands helps maintain hydrological balance in both ecosystems and local communities, protecting them from potential flood damage.
