“…Time for research to confirm that a continuing threat exists, time to identify more firmly any human activities that exacerbate threats, time to find means whereby humans can continue to work in the forest without further reducing caribou range, and time to develop prescriptions that will ensure availability of alternate wintering areas when current ones become unsuitable through succession, perhaps along the lines suggested by (Racey et al 1992). We believe the actions we have recommended would buy such time.…”

Telemetry, sightings, and tracks in snow from 1978–81, with subsequent observations until 1991, showed that woodland caribou (Rangifer tarandus caribou) did not use cut portions of traditional wintering areas for 12 years after cutting. Two attempts by management personnel to modify commercial cutting patterns for caribou failed to prevent abandoning cut areas. In four instances where entire wintering areas were cut, caribou sightings and tracks decreased drastically or ceased entirely. Caribou in unlogged areas have shown no similar declines. Minimal efforts to ensure caribou survival in commercial forests should include deferral of cutting in caribou wintering areas, protection of calving areas, and accelerated research.

“…In Ontario, where the geographic range of caribou has been dramatically reduced over the last hundred years ( Fig. 1), similar concern has been expressed (DeVos & Peterson, 1951;Cringan, 1957;Darby et al, 1989;Racey et al, 1991;Cumming & Beange, 1993). The widespread caribou declines have traditionally been attributed to habitat disturbance or direct mortality factors.…”

A 3-year field experiment (fall 1990-spring 1993) showed that woodland caribou (Rangifer tarandus caribou) altered their dispersion when logs were hauled through their traditional wintering area. Unlike observations in control years 1 and 3, radio-collared caribou thar had returned to the study area before the road was plowed on January 6 of the experimental year 2, moved away 8-60 km after logging activities began. Seasonal migration to Lake Nipigon islands usually peaked in April, bur by February 22 of year 2, 4 of the 6 had returned. The islands provide summer refuge from predarion, but not when the lake is frozen. Tracks in snow showed that some caribou remained but changed locations. They used areas near the road preferentially in year 1, early year 2, and year 3, but moved away 2-5 km after the road was plowed in year 2. In a nearby undisturbed control area, no such changes occurred. Caribou and moose partitioned habitat on a small scale; tracks showed gray wolf (Cants lupus) remote from caribou but close to moose tracks. No pre¬ dation on caribou was observed within the wintering area; 2 kills were found outside it. Due to the possibility of displacing caribou from winter refugia to places with higher predation risk, log hauling through important caribou winter habitat should be minimized.

“…However, since the 1880s this subspecies has disappeared in the southern part of the range. The present range distribution is north of 50° latitude (Cumming & Beange, 1987;Cumming & Beange, 1993), which approximates the northern limit of commercial timber harvest between Cochrane and Kenora (Racey et al, 1991).…”

Prey specialization and morphological conformation of wolves associated with woodland caribou and moose

Morphological analysis of wolves associated with woodland caribou in late succession boreal coniferous forests north of the commercial cut line and those associated with moose in early succession boreal deciduous forests south of the commercial cut line were studied in Ontario. So-called "moose-wolves" could readily be distinguished from "caribouwolves" in both genders using a few morphological measurements. Wolves associated with woodland caribou were significantly smaller in most measurements, and increased in size within seven years post-harvest as moose totally replaced caribou in the ecosystem. Whether this change in wolf morphology is related to micro-evolutionary change, the migration of larger "moose-wolves" into the area, or both, remains unclear.
