Coordinate: 47° 10' N, 101° 0' W
Basis of coordinate: 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 4712' N, 1010' W and is from Calabrese (1972, Plains Anthropologist)
Climate and habitat
Habitat: temperate broadleaf/mixed forest
Substrate: ground surface
WMT: 24.0
CMT: -16.0
MAP: 420.0

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 10118′1′′W)" and are from Bohrer et al. (2017, Environmental Management)
Life forms: trees
Sites: 34
Site area: 9.476
Sampling methods: line transect
Sample size: 5441
Years: 1969-1970
Minimum size: 10.2cm dbh
Basal area: 28.8000 per ha
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)
