Recharging Groundwater Supplies - Wetlands sometimes are helpful in recharging groundwater. This function is especially important where groundwater is the sole-source of drinking water or constitutes the major source of usable water. Maintaining Surface Flows - Wetlands frequently serve as groundwater discharge sites, thereby maintaining the quality and quantity of surface water supplies. Fish and Wildlife Habitats - Many species of fish and wildlife depend on wetlands for critical parts of their life cycle. By providing breeding, nesting, and feeding grounds and cover, wetlands are recognized as one of the most valuable habitats for wildlife.
Young fish find food and shelter in the protective vegetation.
Many species of endangered, threatened, or special concern fish and wildlife depend on wetlands. Tidal wetlands are vital to the continued health of vertebrate and invertebrate species of the waters of New York's marine district. In addition, wetlands are habitat for thousands of species of the plants of New York. One half of New York's protected native plants, many of which are endangered or threatened, are wetlands species. Nutrient Production and Cycling - Wetlands are one of the most ecologically productive systems on earth, converting sunlight and nutrients into food sources for animals.
