Pederson in Greenbrook Sanctuary in Tenafly, NJ. These data were collected for a dendroecological study of southern temperate trees growing at or near a northern range margin. They are growing on top of the Palisades along the Hudson River on thin soils and in a fairly dense forest with closed-canopy conditions. Detrending of these raw data should be conducted with closed-canopy or forest interior conditions in mind.\n# \n# The raw data in this collection contains values of -8888 for years where the rings were distorted or otherwise not useful for dendroclimatology.

We reconstruct 472 years of moisture availability for the NYC watershed to place these emergencies in long-term hydroclimatic context. Using nested reconstruction techniques, 32 tree-ring chronologies comprised of 12 species account for up to 66.2% of the average May-August Palmer Drought Severity Index. Verification statistics indicate good statistical skill from 1531-2003. The use of multiple tree species, including rarely-used species that can sometimes occur on mesic sites like Liriodendron tulipifera, Betula lenta and Carya spp., seems to aid reconstruction skill. Importantly, the reconstruction captures pluvial events in the instrumental record nearly as well as drought events and is significantly correlated to precipitation over much of the northeastern US. While the mid-1960s drought is a severe drought in the context of the new reconstruction, the region experienced repeated droughts of similar intensity, but greater duration during the 16th and 17th centuries. The full record reveals a trend towards more pluvial conditions since ca 1800 that is accentuated by an unprecedented, 43-year pluvial event that continues through 2011. In the context of the current pluvial, decreasing water usage, but increasing extra-urban pressures, it appears that the water supply system for the greater NYC region could be severely stressed if the current water boom shifts towards hydroclimatic regimes like the 16th and 17th centuries.","pubRank":"1"}],"site":[{"NOAASiteId":"54563","siteName":"Greenbrook Sanctuary","siteCode":null,"mappable":"Y","locationName":"Continent>North America>United States Of America>New Jersey","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["41","-74.13"]},"properties":{"southernmostLatitude":"41","northernmostLatitude":"41","westernmostLongitude":"-74.13","easternmostLongitude":"-74.13","minElevationMeters":"61","maxElevationMeters":"61"}},"paleoData":[{"dataTableName":"NJ003","NOAADataTableId":"23633","earliestYear":1818,"mostRecentYear":2000,"timeUnit":"CE","earliestYearBP":132,"mostRecentYearBP":-50,"earliestYearCE":1818,"mostRecentYearCE":2000,"coreLengthMeters":null,"dataTableNotes":null,"species":[{"speciesCode":"CYGL","scientificName":"Carya glabra (Mill.)
