Tree ring widths from mesic and upslope locations at the Coweeta Hydrologic Laboratory

This data publication contains raw tree ring widths for individual trees in the Coweeta Basin, which is within the Coweeta Hydrologic Laboratory in western North Carolina. Transects extending from stream edge to ridge were established in 22 forest stands which were classified as mesic or upslope locations. Fifteen to forty trees per stand were cored one meter from the ground, between 2005 and 2010, from six different species (ACRU=Acer rubrum L., BELE=Betula lenta L., LITU=Liriodendron tulipifera L., QUAL=Quercus alba L., QUMO=Quercus montana Willd., and QURU=Quercus rubra L.). Tree cores dated back as far as 1966.The purpose of this study was to try to examine forest tree growth response to hydroclimate variability in the southern Appalachians.Original metadata date was 06/15/2018. Minor metadata updates were made on 09/06/2019.
