Floodplains play a crucial ecological role in nutrient cycling by acting as natural buffer zones. They capture and filter nutrients from surface runoff, which helps maintain water quality in adjacent aquatic ecosystems. Additionally, during flood events, they store and release water, facilitating the cycling of essential elements like nitrogen and phosphorus. This process fosters the productivity of surrounding habitats and supports a diverse range of species. The floodplain's ability to recharge groundwater aquifers also ensures the sustainability of nearby ecosystems, highlighting their importance in maintaining ecological balance.
