Book excerpt: Outdoor recreation extends human influence on landscapes beyond built environments but is often thought to be compatible with wildlife conservation. Human capability as a highly efficient predator creates a strong selective force on wildlife, analogous to natural predation risk, regardless of trophic level. Behavioral responses have been observed across taxa but linking these changes in behavior to changes at the population-level represents an important step in understanding and mitigating the impact of our everyday presence on ecosystems. Here we present results of the habitat selection exhibited by ten mule deer (Odocoileus hemionus) in response to habitat and human factors and the possible influences on density. Mule deer abundance is generally declining throughout their range and disturbance on winter range presents a possible limiting factor. Winter range is geographically constrained, has increased movement costs associated with snow, and reduced forage quality. Pinyon-juniper forest on winter range has been managed to provide better habitat for ungulates. Disturbance associated with human activity could further limit deer winter habitat. Mule deer on our study area show differential habitat use and movement characteristics with time of day, and intensity of human disturbance. Habitat selection for mule deer was modelled using integrated step selection analysis (iSSA). Mule deer increasingly selected for forest land cover as human presence increased. Deer showed different movement responses with increasing human presence depending on the time of day. Changes to habitat selection, and movement patterns have important implications for habitat management of winter range and potential costs to deer populations. Pairing our movement data with camera data, we found evidence for a low density of mule deer on our winter range compared to winter ranges across Colorado possibly caused by human recreation. Low densities of mule deer has implications for the role density-dependent effects play in modifying the impact of recreation. Our study provides critical information on the role human recreation plays in modifying the effectiveness of habitat management on deer winter ranges and possible scenarios this may scale up to impact mule deer populations.

Book excerpt: Converting wildlife habitat to agricultural monoculture is one of the greatest drivers of habitat loss and can be a severe threat to many wildlife species. However, because mule deer (Odocoileus hemionus) typically live in rugged, less arable landscapes, little is known about how they use habitat fragmented by agriculture. Using Global Positioning System (GPS) data from a partially migratory herd of 62 adult female mule deer from 2018-2022, we examined migration strategies and modeled habitat selection at three spatial scales in southeastern Washington, which is a mosaic of mostly privately owned cereal grain agriculture, shrubland, grassland, and restored cropland in the Conservation Reserve Program (CRP). A minority of the mule deer population was migratory (30%), with relatively short and fast migrations. During migration, they primarily selected for shrubland and grassland in both fall and spring. Mule deer used various components of the landscape throughout the year but selected grassland as their highest-ranked habitat year-round when selecting for home ranges within the study area (second order) and in winter when selecting habitat within their home ranges (third order). During summer, mule deer focused on shrubland and forested habitats within their home range, likely because it provided increased security and thermal cover for fawn-rearing. In the winter, they selected agricultural habitats to a greater degree, which might reflect the growing winter wheat (Triticum aestivum) providing more nutrition during that time. Survival from birth to recruitment into the adult population can greatly influence population dynamics of wild ungulates like mule deer and is affected by both nutrition and cover found in high-quality habitats. We used the GPS data from our population to create resource selection function models during parturition and early fawn-rearing and for fawn bed site characteristics (fourth order). We searched for fawns and fawn bed sites in 2021 and 2022 and used a parturition model to predict birthing events of collared females for which we were unable to find fawns in 2018-2022. For parturition, fawn-rearing habitat, and fawn bed sites, vegetation types that provided more vertical structure, including shrubs and trees, were consistently selected and agriculture avoided. Both intact (i.e., never plowed) shrubland and CRP shrubland were equally selected. These vegetation types provided vertical and horizontal concealment cover for fawns that were also important characteristics of fawn bed site selection. Our research suggests that to promote sustainable populations of mule deer in a landscape dominated by agriculture, managers and landowners could increase the prevalence of quality shrubs and trees where possible to improve habitat and continue support for the CRP program that provides economic incentive to restore croplands for the benefit of wildlife like mule deer.

This book was released on 1988 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern cattle were having negative impacts on female mule deer prompted a study of their relationships on summer range in the Sierra Nevada. There were three phases of the study: determine the influence of cattle grazing leve on habitats; determine habitat selection patterns of radio collared does and cattle; determine the influence of cattle grazing level on doe home range and spatial use patterns. To examine these relationships, the McCormick Creek Basin was divided into three grazing units for manipulating cattle stocking level. Home ranges increased in area as grazing level increased, with deer more evenly using their home ranges. Observations indicated that does mainted greater distances from cattle than expected and temporarily avoided areas of overlap when cattle were present. With the exception of aspen stands, deer did not avoid areas grazed by cattle. Consistent with competition theory, cattle caused deer to increase browse consumption, alter their habitat use patterns to include undesirable habitats, enlarge their home range areas, and temporarily avoid cattle.--Adapted from abstract.

Download or read book Survival Activity Patterns Movements Home Ranges and Resource Selection of Female Mule Deer and White tailed Deer in Western Kansas written by Talesha Karish and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: White-tailed deer (Odocoileus virginianus) and mule deer (O. hemionus) occur in sympatric populations across the Great Plains in North America. Mule deer abundance and occupied range has been declining during the past three decades while white-tailed deer abundance and occupied range has been increasing. Factors contributing to the dichotomous population growth and distribution patterns across their sympatric range are unknown, but potentially include differential survival, space use, and resource selection, all of which may be contributing to indirect competition that may be negatively affecting mule deer populations. Overlap in resource use or space use between mule deer and white-tailed deer could be evidence of competition or competitive exclusion. Activity patterns could provide insights for temporal segregation or competition. Differential space use could allow these species to spatially segregate and co-occur without competing for the same resources. My objectives were to 1) estimate annual and seasonal survival rates, 2) identify cause-specific mortality of adult female mule deer and white-tailed deer, 3) compare behavior patterns between adult mule deer and white-tailed deer of both sexes at seasonal and fine temporal period scales, 4) evaluate the difference in movements between adult female mule deer and white-tailed deer at seasonal and fine temporal scales, 5) test for differences in home range area and composition of adult female mule deer and white-tailed deer at seasonal and fine temporal scales, and 6) evaluate differences in seasonal multi-scale resource selection by female mule deer and white-tailed deer in western Kansas. I deployed collars on 184 pregnant females (94 mule deer and 90 white-tailed deer) at two different study sites in western Kansas (North, South) over three years, 2018, 2019 and 2020. Each deer received a high-resolution GPS/VHF collar that recorded hourly locations, activity accelerometer data along 3 axes, and used an activity sensor to identify mortality events. I used a Kaplan-Meier model to estimate cumulative weekly and annual survival and fit a hazard function to each survival model. I tested for relative influence of factors on estimated survival. I categorized activity points into three behavioral states (feeding, resting, and running). I converted activity points into a proportion of total behavior for each deer and tested for differences in the proportion of behavior categories between species and among seasons. I calculated individual hourly and daily movements seasonally and compared them between species and among seasons. I calculated annual and seasonal 95% home ranges and 50% core areas for each individual deer using a Biased Brownian Bridge movement model. Using logistic regression, I modeled resource selection by mule deer and white-tailed deer at the landscape scale, within home range scale, and within the core home range to identify selection for potential habitat variables and cover types. There was no difference in annual survival of adult female deer between species (mule deer [0.78 ± 0.04] and white-tailed deer [0.77 ± 0.05]). Harvest was the leading known cause of female mortality at 14% of the total mortality, but it was low compared to other studies in the Great Plains. Behavior of both species was similar in all seasons except for rut for males. In rut, males doubled their running behavior. Firearm season produced no changes in behavior for either species or sex. However, the greatest movements and home ranges were in the firearm season. There were greater movements and home ranges in the cold seasons than in the warm seasons. Mule deer were found to use steeper slopes than white-tailed deer, and white-tailed deer used riparian and woodland areas more than mule deer. Habitat patches enrolled in the U.S. Department of Agriculture Conservation Reserve Program were strongly selected by both species in every season and scale. Managers should focus on preserving CRP to stabilize the mule deer population. Given harvest rates of females are low, survival of adult females of both species of deer appears to be little affected by harvest, so there is no need to alter harvest rates of either species.

This book was released on 2023-04-27 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Black-tailed and mule deer represent one of the largest distributions of mammals in North America and are symbols of the wide-open American West. Each chapter in this book was authored by the world’s leading experts on that topic. Both editors, James R. Heffelfinger and Paul R. Krausman, are widely published in the popular and scientific press and recipients of the O. C. Wallmo Award, given every two years to a leading black-tailed and mule deer expert who has made significant contributions to the conservation of this species. In addition, Heffelfinger has chaired the Mule Deer Working Group sponsored by the Western Association of Fish and Wildlife Agencies for more than 15 years. This working group consists of the leading black-tailed and mule deer experts from each of 24 states, provinces, and territories in western North America, putting them at the forefront of all conservation and much of the research on this species. The book represents all current knowledge available on these deer, including how changing conditions such as fires, habitat alteration and loss, disease, climate change, socio-economic forces, energy development, and other aspects are influencing their distribution and abundance now and into the future. It takes a completely fresh look at all chapter topics. The revisions of distribution, taxonomy, evolution, behavior, and new and exciting work being done in deer nutrition, migration and movements, diseases, predation, and human dimensions are all assembled in this volume. This book will instantly become the foundation for the latest information and management strategies to be implemented on the ground by practitioners and to inform the public. Although this book is about deer, the topics discussed influence most terrestrial wildlife worldwide, and the basic concepts in many of the chapters are applicable to other species.

This book was released on 2010 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
