Geography
Country: United States

State: North Dakota

Coordinate: 47° 10' N, 101° 0' W
Latlng basis: based on nearby landmark

Geography comments: sites run up and down the Missouri River and are roughly centered on Sanger in Oliver County (basis of coordinate)
altitude of 1696 feet is for the Cross Ranch site at 47º12' N, 101º0' W and is from Calabrese (1972, Plains Anthropologist)

Environment
Habitat: temperate broadleaf/mixed forest

Substrate: ground surface

WMT: 24.0

CMT: -16.0

MAP: 420.0

Habitat comments: "bottomland hardwood forest"
MAP stated in text; CMT and WMT are for "at BNI Coal approximately 5 km southeast of Center in Oliver county, North Dakota (lat 47° 6′54′′N long 101°18′1′′W)" and are from Bohrer et al. (2017, Environmental Management)

Methods
Life forms: trees

Sites: 34

Site area: 9.476

Sampling methods: line transect

Sample size: 5441 individuals

Years: 1969-1970

Net or trap nights: 0

Size min: 10.2

Basal area status: per ha is

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)
