Habitat comments: "Land uses in the North Fork watershed are diverse, consisting of ranches, national forests and state lands, conservation easements, and exurban residential developments... Nearly 1400 houses are located in the nearly 660 km2 study area... The vegetation community is dominated by Rocky Mountain Ponderosa Pine Woodland and Rocky Mountain Lower Montane-Foothill Shrubland" and dominant grasses are listed

Years: 2012, 2013
Seasons: winter, spring, summer
Nets or traps: 27
Net or trap nights: 4347
Camera type: digital
Cameras paired: no
Trap spacing: 2.160
Sampling comments: "Fifty-four final sites were selected... All points were located a minimum of 500 m apart (range: 500–3819 m)... Data collection occurred during the summer (May–August 2012) and winter (December 2012–March 2013). At each study site, an unbaited remotely-triggered camera was placed within 150 m of the original point. Twenty-seven remotely-triggered cameras (Cuddeback Capture, Primos TruthCam 35, or Wildgame Innovations Micro Red 4) outfitted with security boxes were placed at half of the study sites and remained in their locations for six weeks (42 trap nights)... The cameras were then moved to a new set of 27 sites for another six weeks (42 trap nights)... There were 2147 total detections in the summer season (2138 trap nights) and 1034 detections in the winter season (2209 trap nights)"
