Habitat comments: "Late-successional hardwood stands... we noted no cut stumps or old logging roads; however, the outer portions, lower in elevation and slope gradient, likely experienced some direct human disturbance including logging, fire, and grazing prior to 1924... Grazing and fire have been excluded from the forest since that time... The climate is classified as humid mesothermal"
Methods
Life forms: trees
Sites: 27
Site area: 1.08
Sampling methods: quadrat
Sample size: 463 individuals

Sampling comments: "Our study was specifically focused within an approximately 60-ha portion within the core section of the 91-ha reserve... we established 27 0.04-ha fixed-radius (r = 11.29 m) plots throughout the inner core of the HFNA... Plots were arranged in a systematic grid pattern at 188-m (E-W) x 135-m (N-S) spacing"
