Geography comments: "a 25-km2 wetland located on the south side of Albemarle Sound in eastern North Carolina... owned by North Carolina State University"

Environment
Habitat: temperate broadleaf/mixed forest

Protection: unprotected

Substrate: ground surface

Disturbance: recent fire, hunting, selective logging

WMT: 21.7

CMT: 10.4

MAP: 1265.0

Habitat comments: a "working forest with active, small-scale timber harvests, prescribed by burning, and hunting... a forested wetland with secondary and tertiary dirt roads bordered by canals and has 5 land-cover types: non-riverine swamp forest, peatland Chamaecyparis thyoides L. (Atlantic White-cedar) forest, mesic mixed-hardwood forest, tidal cypress–gum swamp, and tidal freshwater marsh. Based on 50-year climate records, monthly mean temperatures ranged from 10.4 ºC to 21.7 ºC and rainfall averaged 126.5 cm per year"

Methods
Life forms: carnivores, rodents, ungulates, other small mammals

Sampling methods: no design, automatic cameras

Sample size: 653 captures or sightings

Years: 2007

Days: 92

Seasons: summer

Nets or traps: 9

Net or trap nights: 0

Camera type: digital

Cameras paired: no

Trap spacing: 2.6

Basal area status: not applicable

Sampling comments: there was "a grid of 2.6-km2 cells... We assigned to each cell (n = 9) 2 scent stations, 1 camera station, and 1 predator-calling station... We placed 1 digital camera (Capture 3.0; Cuddeback Digital, DePere, WI) equipped with an infrared sensor triggered by temperature and movement at 9 of the 18 scent stations... data presented are from June, July, and August of 2007" (presumably meaning there were 92 trap-nights per camera)
