Methods
Life forms: trees
Sites: 34
Site area: 9.476
Sampling methods: line transect
Sample size: 5441 individuals
Years: 1969-1970
Size min: 10.2
Basal area: 28.8
Sampling comments: "We selected 34 stands of forest... We used the quarter method... to sample the overstory. A stratified random sampling design was used to locate 40 sample points per stand" (total number of individuals is 34 x 40 x 4 = 5440 and reported tree density is 574.1, so the site area is equivalent to about 9.4757 ha; entered counts by species were back calculated from per ha values)
