Geography
Country: United States
State: Virginia

Coordinate: 38.887089° N, -78.164650° W
Basis of coordinate: stated in text
Geography comments: a "1295 ha campus... contiguous with the nearly 81, 000 ha forest of Shenandoah National Park"
Climate and habitat
Habitat: temperate broadleaf/mixed forest
Protection: other protected area
Substrate: ground surface
Habitat comments: "Forest canopies are dominated by Tulip Poplar (Liriodendron tulipifera), Ash (Fraxinus spp.) and a suite of Oak (Quercus spp.) and Hickory (Carya spp.) species... The climate is classified as humid subtropical, with hot humid sum- mers and mild cool winters. Snowfall is irregular but common after January"
Methods
Life forms: carnivores, rodents, ungulates, other small mammals
Sampling methods: no design, automatic cameras
Sample size: 965
Years: 2013, 2014
Seasons: winter, summer, autumn
Nets or traps: 30
Net or trap nights: 762
Camera type: digital
Cameras paired: no
Trap spacing: 0.500
Sampling comments: "The entire SCBI property was overlaid with a systematic grid (500m x 500m) with a random starting point, and with grid center points designated as target locations for a paired camera station" with one "feature camera" per point
"We collected data for this study during the months of June through December (though only four camera deployments extended into December) in both 2013 and 2014
cameras were SpyPoint model BF-7 and Reconyx models RC-60 Covert IR and HyperFire HO Covert IR
"cameras were set at or below knee height (~ 40cm)... Photo series at the same camera for the same species were considered independent if 10 minutes passed with no captures of the respective species"
"total camera nights by camera = 2742" for the 108 cameras in the entire study, of which 30 were placed on logs at features, so there were approximately 761.67 camera nights
