• Abstract:
  • Sound cores were collected from 647 trees: 433 beech, 146 white oak, and 68 black oak (East end N = 347, West end N = 300; tall N = 154, intermediate N = 198, dwarf N = 109 and outside-of-plot oak species N = 132). A relatively small number (N = 54) of beech and oak cores were retrieved from stands along the coastline and are included in species analyses, but not in analyses of structural types because of the limited occurrence of this type. Cores were taken as close to the base of each tree as possible (30 - 40 cm from the base) in order to determine the most accurate establishment date. Cores were dried, mounted, and sanded with increasingly fine sandpaper to reveal the cellular structure. Tree rings were counted and measured to the nearest 0.01 mm using a Velmex measuring system (East Bloomfield, NY, USA). Cores were used to determine stand age structure for modern forests, and to estimate the diameters of trees at the time of hurricanes by summing ring widths from the innermost ring to the hurricane year (excluding rotten cores and cores that substantially missed the pith). All cores were used in the radial growth analysis. A sub-sample of beech (N = 92) white oak (N = 58) and black oak (N= 25) were visually cross-dated, and verified using the program COFECHA. Cross-dated cores were used to examine the yearly growth response to hurricanes.
