Geography
Country: Romania
Coordinate: 46° 48' N, 24° 9' E
Latlng basis: based on nearby landmark
Geography comments: "4900 km2 in the foothills of the Carpathian Mountains in southern Transylvania" (map indicates that the region is roughly within the counties of Sibiu and Brasov and centered perhaps to the east of the city of Sibiu, basis of coordinate)
Environment
Habitat: temperate broadleaf/mixed forest
Substrate: ground surface
MAT: 8.8
MAP: 642.0
Habitat comments: "The region contains 28% forest, 24% pasture and 37% arable land. The remaining land cover includes villages, water bodies and permanent crops. Forests are dominated by hornbeam (Carpinus betulus), oak (Quercus sp.) and beech (Fagus sylvatica)... We surveyed wild mammal, human and dog presence in forests"

Life forms: carnivores, primates, ungulates
Site area: 300000.0
Sampling methods: no design, baited, automatic cameras
Sample size: 3152 captures or sightings
Years: 2013
Net or trap nights: 3042
Camera type: digital
Cameras paired: no
Trap spacing: 1.5
Basal area status: not applicable
Sampling comments: "We surveyed... using remote, heat and motion, passive infrared Bushnell Trophy Cam HD Max cameras between May and August 2013... we divided the study area into grid cells of 5 x 5 km... n = 120" and "placed one camera in the middle of each grid or in the nearest forest patch if no forest was present... Cameras were rotated in four rounds... cameras were spaced more than 1.5 km apart... We used 179 camera locations in total... However, only 138 locations were used for modelling... we placed cameras alongside animal and human paths, and used a lure of honey and wolf urine to attract bears and wolves, respectively. Lures were deployed at 75% of the locations (selected randomly)" (exact number of cameras is unclear; effective surveyed area was 5 x 5 x 120 = 3000 km2)
