Whole Ecosystem Restoration Through Liming of Honnedaga Lake Tributary Watersheds
Summary Acid rain levels in the Adirondack region have substantially declined and recovery from acid rain is underway. Recovery is being limited by the depletion of soil calcium that occurred over past decades. Not only is calcium needed for neutralizing acidity, it is an essential nutrient for terrestrial and aquatic ecosystems. However, recovery of soil calcium has not yet been observed. Whole-ecosystem restoration through watershed liming, possibly combined with in-stream liming, may provide a practical option for stimulating recovery of certain acid-sensitive, high-value natural resources. Information from past liming efforts, however, is insufficient for determining the degree of success that could be achieved...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
