Methods
Life forms: trees
Sites: 1
Site length: 20116.801
Site width: 20.117
Sampling methods: belt transect
Sample size: 12741 individuals
Size min: 12
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. 180)
