An Assessment of Forest Health and Soil Nutrient Status to Determine the Effects of Logging Practices on Water Quality in New York City's West-of-Hudson Watersheds

Dates

End Date
2011

Summary

The growth of temperate forests is typically limited by the availability of nitrogen. Elevated concentrations of nitrate in some Catskill Mountain streams, which are tributary to New York City's water-supply reservoirs west of the Hudson River, indicate that the forests of this region are at the early stages of nitrogen saturation. That is, nitrogen is available in excess of the amount utilized by vegetation and soil microorganisms in the forests. Nitrogen saturation is a concern because the mobile nitrate that moves through soil is accompanied by other nutrients such as the base cations calcium and magnesium that are necessary for forest growth but are present in short supply in some Catskill soils. And, nutrient cycling and forest [...]

typeShort Project Description
valueDeveloping best management practices for forested watersheds should include harvesting practices that are designed with regard to soil nutrient status. To develop such practices, the nutrient cycling processes that control water quality in forested watersheds must be understood through scientific studies.
