Habitat Use by White-tailed Deer in Relation to Winter Range Silvicultural Treatments in the Thompson River Drainage, Northwestern Montana

Book Description
"A study to evaluate white-tailed deer winter range use in relation to forest stand and weather conditions was conducted during three winters from 1983-1986. Data were collected from 16.1 km (10 mi.) of ground transects and 20 radio-collared deer located on winter range in the study area. One hundred thirty seven telemetry locations were evaluated with a GEOSCAN cartographic program. The program scanned 40 ha (100 ac.) around each location to generate a frequency distribution of cover types from a digitized vegetation map. A winter severity index was used to classify transect and telemetry observations of deer use into mild, moderate and severe winter condition categories. Under mild winter conditions, white-tailed deer used 13 cover types in proportion to their availability on the winter range. Observed proportion of cover type use by deer under moderate and severe winter conditions differed from that expected. Deer utilized openings, lightly stocked plantations, and riparian pole-sized timber significantly less than availability and preferred upland pole and riparian sawtimber-sized stands. Multiple regression analysis of snow depth, percent canopy closure and aspect vs. deer use was significant, especially when snow depth exceeded 40 cm (13 in.). Discriminant function analysis was not particularly effective in identifying habitat variables to predict deer occurrence under mild and moderate conditions. The discriminating variables for severe winter conditions were one tree basal area variable, one diversity related variable, one aspect variable, and one stand type variable. Reductions in deer use one year following timber harvest ranged from 52-85% and were related to reductions in canopy closure. Overall rankings of cover type use derived from transects did not differ significantly from rankings obtained by telemetry. However, large differences in individual cover type rankings between techniques were observed in conifer plantations and upland sawtimber cover types. Rankings of cover type use derived from both techniques were correlated. The relationship between forest structural components on winter ranges and the silvicultura1 practices which affect them is discussed. Guidelines for winter range si1vicultcra1 treatments are proposed. Management implications of the guidelines are discussed. The distribution of winter range structural types in the study area was within recommended guidelines"--Leaf ii.
