Abstract

    Tree cores were collected from five species of tree along an elevational gradient, replicated along three transects (watersheds) on Mt. Mansfield, VT. Note that these data and associated metadata have been archived on the DendroEcological Network located at www.uvm.edu/femc/dendro

    Methods

    • Current Methods
      • Dendrochonology
        • Method Description: Extracted two tree cores per tree perpendicular to dominant slope at stem DBH.
        • Instrumentation: 5 mm increment borer

      • Tree ring measurement and crossdating
        • Method Description: Tree rings were measured to nearest 0.001 mm using Velmex sliding stage set up and crossdated using the list method
        • Instrumentation: Velmex sliding stage apparatus, microscopeSoftware: COFECHAQuality Control Measures: Cores were rejected if they did not correlate to the master (under the critical threshold)

      • Climate correlations
        • Method Description: Bootstrapped response function analysis over the common period of 1925-2012
        • Software: dplR and treeclim packages for R Quality Control Measures: alpha value set to 0.01 to account for multiple correlations
