Winter (01 Jan - 15 Apr) habitat selection by Shiras moose (Alces alces shirasi) within individual home ranges was investigated using global positioning (GPS) collars on 23 adults (7 M, 16 F) during 2 winters (2005, 2006) of differing snow pack in the Snowy Range of the Medicine Bow mountains, southeastern Wyoming. Although wide variation was observed among animals, moose commonly selected for riparian shrub, deciduous forest, and mixed forest cover types. Mixed mountain shrub was occupied extensively by several moose and was used more often towards the end of winter, as moose tended to minimize movements and increasingly use other cover types in place of riparian shrub. Differences in selection ratios between sexes were not detected for any cover type and differences between years were minimal among moose collared both winters. Diets of moose during winter were also investigated through fecal analysis. Willow (Salix spp) and subalpine fir (Abies lasiocarpa) composed a mean 60% and 30% of moose diets, respectively, with the remaining 10% comprised mostly antelope bitterbrush (Purshia tridentata), mountain mahogany (Cercocarpus montanus), or Saskatoon serviceberry (Amelanchier alnifolia). Diets were more diverse in the year of less snow pack. Patterns of habitat selection by collared moose did not differ between winters, as would be expected if forage availability differed considerably between years. This was likely because moose GPS locations did not overlap fecal collection sites and forage item selection within those sites occurs at a different scale than the selection of cover types within home ranges. A literature-based winter habitat suitability index (HSI) model was developed from common geographic information system (GIS) layers and scrutinized with GPS locations of sampled moose. However, the HSI model was poorly predictive of winter habitat occupancy. More accurate resource selection function (RSF) models were constructed by integrating moose GPS locations with more refined GIS data layers. Numerous vegetative, topographic and distance variables were calculated across the study area and were used in a forward stepwise general linear regression model to identify important components of moose habitat during winter and non-winter seasons. Distance to forest edge and distance to deciduous forest were significant predictors in both seasons. Slope also influenced habitat use year-round, although slope2 was a factor in the winter model. While distance to riparian shrub was predictive of moose habitat occupancy during winter, the total area of riparian shrub within a circular 1 km radius was a better determinant of summer habitat use. The combination of variables in the winter model accounts for the distribution of willow, subalpine fir, mountain mahogany and antelope bitterbrush, in proximity to forest cover. The non-winter model demonstrated the nearly exclusive importance of riparian shrub habitat in proximity to thermal cover across a wider range of elevations than during winter. A technique was employed to make spatial calculations of the potential range capacity for moose using the winter RSF map predictions observed within individual moose winter home ranges. A wide range of capacity estimates were computed by adjusting the minimum habitat quality and maximum size parameters observed in moose winter ranges. Because not all moose are energetically capable of occupying the maximum observed home range size or competing for the highest quality habitat, more sensible estimates were produced using the mean winter home range quality and size inputs.

We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our intended audience is field ecologists in general and, in particular, wildlife and fisheries biologists who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function (RSF), where this is a function of characteristics measured on resourceunits such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.

The guidelines presented in this publication have been prepared to assist resource managers in the standardized inventory of habitat, and in some cases, populations of selected species of wildlife that potentially occur within the Crown forests of Ontario. The first section describes generalized methods and techniques, including information on personnel and training, planning of field surveys, wildlife habitat inventory and geographic information system technology, and recording the location of observations. The second and main section presents methodologies to identify and delineate featured species habitats. Chapters in this section provide methodologies regarding: moose aquatic feeding areas, bald eagle and osprey nests, and great blue heron colonies; moose winter habitat; white-tailed deer winter habitat; provincially featured birds, mammals, reptiles, and plants; woodland caribou winter habitat, calving and nursery sites; nests of red-shouldered hawk and great gray owl; southern flying squirrel habitats; West Virginia white butterfly habitats; and other vulnerable birds, mammals, and reptiles that can be locally featured.
