A Perliminary Study of the Effects of Juvenile Spacing on Wildlife Habitat use During Winter in the Interior Douglas-fir Zone of British Columbia

The effects of juvenile spacing (non-commercial thinning) on wildlife were studied during winter in Douglas-fir forests near 100 Mile House, British Columbia. Snowshoe hares did not use recently spaced, mature IDFb2 forests in the winter after the fresh slash was covered by snow, but did use unspaced strips left in spaced blocks. There was some evidence that wider strips of unspaced forest were preferred. Mule deer, moose, and coyotes selected for trails created through slash. Future research is necessary to determine long- and short-term effects of spacin~ on wildlife in both the summer and winter.
