Human activities such as encroachment, urbanization, agriculture, and pollution threaten the wetland's habitat. Economic ImportanceWetlands are economically important to people. Hydrology also influences the structure and function of wetland ecosystems through its influence on species richness, productivity, rates of organic matter accumulation, and nutrient cycling. Eventually, these plants are followed by water-loving grasses and sedges. You cannot download interactives.
