Country: United States
State: Illinois

Coordinate: 40° 7' N, 88° 12' W
Basis of coordinate: based on nearby landmark
Geography comments: "about five miles northeast of Urbana" (coordinate based on Urbana)
Climate and habitat
Habitat: temperate broadleaf/mixed forest
Substrate: ground surface
WMT: 23.9
CMT: -4.6
MAP: 1010.0
Habitat comments: trees are principally white elm, red elm, and sugar maple; "Until 1917 the area was grazed and a few trees had been cut down; since then it has been undisturbed and can be considered a heavily wooded 'virgin area"
climate data are for Champaign and are from Lin et al. (2004, Plant Ecology)
Life forms: rodents, other small mammals
Sampling methods: quadrat, baited, snap traps
Sample size: 44
