Pogue Creek Natural Area
Basic information
Sample name: Pogue Creek Natural Area

Reference: J. L. Hart and H. D. Grissino-Mayer. 2009. Gap-scale disturbance processes in secondary hardwood stands on the Cumberland Plateau, Tennessee, USA. Plant Ecology 201(1):131-146 [ER 2116]
Country: United States
State: Tennessee

Coordinate: 36° 31' N, 84° 53' W
Basis of coordinate: stated in text
Geography comments: no details given
elevation 260 to 490 m
Habitat: temperate broadleaf/mixed forest
Altered habitat: secondary forest
Substrate: ground surface
MAT: 13.0
WMT: 23.0
CMT: 2.0
MAP: 1370.0
Habitat comments: "humid mesothermal" and within "the Mixed Mesophytic Forest Region... forests are intermediate between mixed mesophytic and Quercus-Carya types... The forest was established in the late 1920s after the cessation of local logging operations"
Life forms: trees
Sites: 40
Site area: 0.171
Sampling methods: belt transect
Sample size: 473
Minimum size: 5.0cm dbh
Sampling comments: "Canopy gaps (n = 40) were located along transects throughout the reserve using the line intersect method" and sampling was within each gap, with counts only pertaining to "true canopy gaps"; "Total transect length was 4.47 km, with 15% of the total length in expanded gaps and true gaps, and 6% in true canopy gaps only"
total site area is nowhere stated but is apparently 40 gaps x mean gap size 42.78 m2 = 0.17112 ha; this figure is consistent with the minimum density reported in Table 2
