Climate and habitat
Habitat: temperate coniferous forest
Substrate: ground surface
MAT: 2.6
MAP: 640.0
Habitat comments: "within the Montane Spruce... bioclimatic zone" which "has a cool, continental climate with cold winters and moderately short, warm summers"
"Old-growth stands had a tree species composition of lodgepole pine, Douglas-fir, subalpine fir, and spruce, and ranged in average age from 70 to 133 yr"
MAT 0.5 to 4.7 C, MAP 380 to 900 mm
Life forms: carnivores, rodents, other small mammals
Sites: 3
Site area: 3.000
Sampling methods: quadrat, baited, other traps
Sample size: 542
Years: 1995 - 1997
Days: 39
Seasons: spring, summer, autumn
Nets or traps: 147
Net or trap nights: 5733
Sampling comments: "five sampling periods" per year over three years except that "One old-growth grid had only three sampling periods for 1997"; traps were open for three days during each sampling period; there were three sampled stands each including a grid, and "Trapping grids (1 ha) had 49 (7 x7 array) trap stations at 14.3-m intervals with one Longworth live-trap at each station... Traps were supplied with whole oats and carrot, and cotton as bedding"; total trapping effort was therefore 13 x 3 x 3 x 49 = 5733 trap nights
