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. Some tidal wetlands exceed even tropical rainforests in energy conversion.
Wetlands also serve as filters for sediment and organic and chemical nutrients.
These components are recycled in wetlands, where the nutrients are broken down and reentered into the food web. Recreation - Hiking, bird watching, hunting, fishing, trapping, boating, photography, and camping are some of the recreational uses provided by wetlands. Over 12 million New Yorkers annually participate in these outdoor activities. Open Space - Wetlands are often the only undeveloped areas along crowded riverfronts and coastal regions or in urbanized areas. In some areas, real estate near open space, such as wetlands, command significantly higher prices.
