Environment
Habitat: tropical/subtropical moist broadleaf forest

Substrate: ground surface

WMT: 27.4

CMT: 25.4

Methods
Life forms: trees

Sites: 1

Site length: 20116.801

Site width: 20.117

Sampling methods: belt transect

Sample size: 12741 individuals

Net or trap nights: 0

Size min: 12.0

Basal area status: not stated

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)
