Methods
Life forms: trees
Sites: 1
Site area: 40.469
Site length: 20116.801
Site width: 20.117
Sampling methods: belt transect
Sample size: 12552
Minimum size: 12.0inches girth at breast height
Sampling comments: see table 1
counts are based on "1000 chains (20.1 km) of belt transect records" = 66, 000 feet = 20.1168 km (p. 174) and I believe the transect is 1 chain = 66 feet wide because an acre is 1 chain on each side and the total area is apparently 100 acres = 40.469 ha (see p. 179)
