Book Description
Author Jim Heffelfinger presents a wide array of data in a reader-friendly, well-organized way. With a clear mission to make his information not only helpful, but entertaining and attractive as well, each chapter focuses on a specific aspect of understanding deer. The clear, detailed table of contents will help readers flip right to the section they want to investigate. Not just hunters, but anyone who is interested in the deer of West Texas, Arizona, New Mexico, southern California, Nevada, Utah, Colorado, northern Mexico, or tribal lands will find this book to be an indispensable resource for understanding these familiar and fascinating animals. “Very few books on the subject of deer in any particular region lend themselves to being complete. Jim Heffelfinger’s book breaks the mold. It is by far the most comprehensive book on mule deer and white-tailed deer in the southwestern part of the United States, including Plains portions of Texas, Colorado, and New Mexico, I’ve ever read. Everything you ever wanted to know about these two deer species can be found in its pages . . . All of this under one cover and written in a style easy enough for the layperson to understand, but scientific enough for the professional biologist . . . Deer of the Southwest is a pleasure to read and should be part of every deer enthusiast’s library.”—Great Plains Research “An important reference for anyone interested in deer in the Southwest—managers and enthusiasts alike. Both enlightening and instructive, Deer of the Southwest is the ultimate source for understanding the history, management, and issues facing this resource. Jim Heffelfinger has solidified his reputation as the premier authority on deer in this region.”—Barry Hale, deer program manager, New Mexico Department of Game and Fish

Book Description
Increased levels of energy development across the intermountain West have created a variety of wildlife and habitat management concerns. Because many of the energy resources in the region occur in shrub-dominated basins (e.g., Powder River, Piceance, Great Divide, and Green River basins), management concerns have focused on native shrub communities and associated species, including mule deer (Odocoileus hemionus). Two of the more pressing concerns are how mule deer respond when critical habitats (e.g., winter range) are impacted by development and how their migration routes can be identified and prioritized for conservation. To address the first, I examined how three types of natural gas well pads with varying levels of vehicle traffic influenced the winter habitat selection patterns of mule deer in western Wyoming. My results showed that mule deer avoided all types of well pads and selected areas further from well pads that received high levels of traffic. Accordingly, impacts to mule deer could likely be reduced through technology and planning that minimizes the number of well pads and amount of human activity associated with them. To address the migration concerns, I developed a quantitative framework that uses global positioning system (GPS) data and the Brownian bridge movement model (BBMM) to: (1) provide a probabilistic estimate of the migration routes of a sampled population, (2) distinguish between route segments that function as stopover sites versus those used primarily as movement corridors, and (3) prioritize routes for conservation based upon the proportion of the sampled population that uses them. Mule deer migration routes were characterized by a series of stopover sites where deer spent most of their time, connected by movement corridors through which deer moved quickly. These findings suggest management strategies that differentiate between stopover sites and movement corridors may be warranted. Because some migration routes were used by more mule deer than others, proportional level of use may provide a reasonable metric by which routes can be prioritized for conservation. Although stopovers appeared to be a prominent feature of mule deer migration routes, the explicit study of stopovers (i.e., stopover ecology) has been limited to avian species. To assess whether stopover ecology was relevant to mule deer, I again used fine-scale GPS data and BBMMs to quantify a suite of stopover characteristics and examine the ecological role of stopovers in the seasonal migrations of mule deer. Mule deer utilized a series of stopover sites in both spring and fall migrations, across a range of migration distances (18-144 km). Overall, mule deer used 1.9 and 1.5 stopovers for every 10 km increase in migration distance during spring and fall migrations, respectively. Stopovers had higher quality forage compared to movement corridors, and forage quality increased with elevation, presumably because of delayed phenology along the altitudinal migration route. Stopovers likely play a key role in the migration strategy of mule deer by allowing them to migrate in concert with vegetative phenology and optimize their foraging during migration. My results suggest stopovers were a critical component in the altitudinal migrations of mule deer and that conservation of stopover sites may improve efforts aimed at sustaining migratory mule deer populations.
