Country: United States
State: Tennessee

Coordinate: 36° 4' N, 86° 54' W
Basis of coordinate: based on nearby landmark
Geography comments: "20 km southwest of Nashville, Tennessee" (apparently adjacent to Edwin Warner Park, basis of coordinate)
elevation 217 to 279 m
Habitat: temperate broadleaf/mixed forest
Substrate: ground surface
MAT: 15.0
WMT: 26.0
CMT: 3.0
MAP: 1210.0
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"
Life forms: trees
Sites: 27
Site area: 1.080
Sampling methods: quadrat
Sample size: 463
Minimum size: 5.0cm dbh

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"
