Book excerpt: White-tailed deer (Odocoileous Virginianus) are considered a dominant and abundant species in forested landscapes in the eastern United States, and deer management, which often involves reducing deer densities, is crucial to keep populations in balance with their habitat. In Pennsylvania, state agencies such as the Pennsylvania Game Commission and the Pennsylvania Department of Conservation and Natural Resources, Bureau of Forestry have implemented deer management programs that use hunter harvest to reduce deer densities in specific geographical areas in order to meet various land-use and human health objectives. We developed a spatially explicit, agent-based model to investigate the intensity of deer removal required to locally reduce deer density depending on the surrounding deer density, dispersal behavior, and size and shape of the area of localized reduction. Our model indicated that a localized reduction was successful for scenarios in which the surrounding deer density was lowest (30 deer/mi2), antlerless harvest rates were >= 30%, and the reduction area was 5 mi2 or larger. Based on the results from our model simulations, we evaluated the effectiveness of a deer management program at reducing deer densities on four forested study areas that meet the criteria for a successful localized deer density reduction. We developed a method to estimate deer density that combines a distance sampling technique with a resource selection model of deer distribution to estimate deer density on the study areas and determine if deer density reductions occurred. In addition, we used data collected from distance sampling surveys and global positioning system (GPS) locations of collared deer on a disease management area (DMA) in Pennsylvania to assess two types of resource selection models: resource selection functions modeled as second-order selection and step-selection functions. We wanted to evaluate if each method resulted in different inferences regarding deer density estimates over four survey periods. Based on our estimates of deer density for the four forested study sites, deer densities are being reduced or maintained on all study areas. For data from deer on the DMA, both resource selection functions and step-selection functions predicted that deer distribution varied temporally. Overall, our analyses provide insight into the factors that contribute to a successful localized deer density reduction, offer a method for estimating deer density that suggests that the Pennsylvania Game Commission is effectively reducing deer densities on certain areas, and indicate that both resource selection functions and step selection functions may be appropriate for identifying temporal variations in deer distributions.

Burns (Jr.) and published by . This book was released on 2021 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic habitat modification, predator extirpation, and reduced hunting pressure have pushed white-tailed deer (WTD; Odocoileus virginianus) populations to unprecedentedly high densities throughout much of eastern North America. Importantly, their selective foraging can depress the abundance of preferred native plant species, increase that of less nutritious ones, and facilitate exotic species invasion. However, few have researched areas where WTD densities have been maintained, for decades, at low levels. Moreover, scant data exists on canopy species regeneration across different-aged canopy gaps, in different habitats, and in areas of historically high and low WTD densities. Here, we ask: 1) across a range of canopy gap ages, does WTD density affect the number and relative cover of native and non-native plant species, in wet and dry habitats?, and 2) does vegetation structure differ in areas of historically low WTD density relative to areas where WTD are excluded via fenced exclosures? - here, an answer of `no' suggests WTD are at or below their carrying capacity. This study took place in and outside of Camp James A. Garfield Joint Military Training Center (C-JAG, Portage Co., OH), which has maintained WTD densities 2-3 times lower than the surrounding areas, since 1955. Excluding WTD at C-JAG for one year did not result in different plant communities, suggesting C-JAG's aggressive WTD management has them at or below their carrying capacity. Relative to surrounding areas, canopy gaps at C-JAG generally harbored a more diverse and abundant assemblage of native species, especially in dry habitats, and lower levels of non-native species in both habitats. Canopy gap age did not affect any response variable, suggesting a low WTD density generally promotes native plant diversity, and reduces the incidence of exotic species, regardless of gap successional stage. Given that energy transfer to higher trophic levels tends to be greater in areas of high native plant diversity, maintaining low WTD densities may facilitate the diversity and abundance of species at higher trophic levels. Lastly, without adequate WTD management, our forests will likely suffer continued native biodiversity loss, altered successional trajectories, and become increasingly dominated by exotic species.

Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Wildlife Society Outstanding Edited Book Award for 2013! Winner of the Texas Chapter of The Wildlife Society Outstanding Book Award for 2011! Winner of a CHOICE Outstanding Academic Title Award for 2011! Biology and Management of White-tailed Deer organizes and presents information on the most studied large mammal species in the world. The book covers the evolutionary history of the species, its anatomy, physiology, and nutrition, population dynamics, and ecology across its vast range (from central Canada through northern South America). The book then discusses the history of management of white-tailed deer, beginning with early Native Americans and progressing through management by Europeans and examining population lows in the early 1900s, restocking efforts through the mid 1900s, and recent, overabundant populations that are becoming difficult to manage in many areas. Features: Co-published with the Quality Deer Management Association Compiles valuable information for white-tailed deer enthusiasts, managers, and biologists Written by an authoritative author team from diverse backgrounds Integrates white-tailed deer biology and management into a single volume Provides a thorough treatment of white-tailed deer antler biology Includes downloadable resources with color images The backbone of many state wildlife management agencies' policies and a featured hunting species through much of their range, white-tailed deer are an important species ecologically, socially, and scientifically in most areas of North America. Highly adaptable and now living in close proximity to humans in many areas, white-tailed deer are both the face of nature and the source of conflict with motorists, home-owners, and agricultural producers. Capturing the diverse aspects of white-tailed deer research, Biology and Management of White-tailed Deer is a reflection of the resources invested in the study of the species’ effects on ecosystems, predator-prey dynamics, population regulation, foraging behavior, and browser physiology.

Available in PDF, EPUB and Kindle. Book excerpt: White-tailed deer (Odocoileus virginianus) population models are used by many states to predict population levels and aid in making management decisions. Delaware did not have a deer population model, so I developed a model and used it to investigate the implications of changes to the harvest. I used survival rates, reproductive rates, harvest data, a population estimate, and spotlight counts to construct the model. The changes to the harvest regime that I considered were permitting Sunday hunting during the opening weekend of the November firearm season, adding 1 week to the November shotgun season, termination of the severe deer damage permits, closing the October antlerless shotgun season, closing the shotgun season in January, closing the muzzleloader season in January, and closing both shotgun and muzzleloader seasons in January. The model began in February 2006 after the conclusion of the 2005-2006 hunting season and I ran the scenarios until August 2014. Without changing the harvest regime, my model predicted the state population to decrease 28% by the fall of 2014. Allowing Sunday hunting during the opening weekend of the main firearm season and adding an additional week onto the main firearm season caused the population to decline at a greater rate by 2014. Terminating the severe deer damage program did not impact the 2014 predicted deer population compared to the scenario without changing the harvest regimes. Closing the October antlerless season and the January shotgun season caused a 23% increase to the 2014 predicted population, in both scenarios. Compared to scenario without changing the harvest regimes, the deer population was 11% greater in 2014 with the January muzzleloader season closed and 37% greater in 2014 with both January shotgun and muzzleloader seasons closed. The model predicted that the differentdeer management zones have very different population levels and harvest rates. To date, the harvest regimes in Delaware have only been changed at the state level but future changes to the harvest regimes should occur at the zone level. Several options are available for managers to increase or decrease the deer population by 2014. Managers can further reduce the deer population by allowing Sunday hunting during the opening weekend of the main firearm season and/or adding an additional week onto the main shotgun season. If managers decide to slow or stop the population decline, then closing the October antlerless season and/or the late January seasons are the best methods. Terminating the severe deer damage assistance program is not an effective method to slow or stop the declining trend, because removing the deer harvested under the program only caused a 4% increase to the 2014 population. Depending on the desired 2014 population level, managers can adjust the harvest regimes accordingly to meet their population goal.

This book was released on 2023-03-31 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2003, a cadre of researchers set out to determine what combination of supplemental or natural nutrition and white-tailed deer population density would produce the largest antlers on bucks without harming vegetation. They would come to call this combination “the sweet spot.” Over the course of their 15-year experiment, conducted through the Caesar Kleberg Wildlife Research Institute at Texas A&M University–Kingsville, Timothy E. Fulbright, Charles A. DeYoung, David G. Hewitt, Don A. Draeger, and 25 graduate students tracked the effects of deer density and enhanced versus natural nutrition on vegetation conditions. Through wet years and dry, in a semiarid environment with frequent droughts, they observed deer nutrition and food habits and analyzed population dynamics. Containing the results of this landmark, longitudinal study, in keeping with the Kleberg Institute’s mission, this volume provides science-based information for enhancing the conservation and management of Texas wildlife. Advanced White-Tailed Deer Management: The Nutrition–Population Density Sweet Spot presents this critical research for the first time as a reference for hunters, landowners, wildlife managers, and all those who work closely with white-tailed deer populations. It explains the findings of the Comanche-Faith Project and the implications of these findings for white-tailed deer ecology and management throughout the range of the species with the goal of improving management.

Available in PDF, EPUB and Kindle. Book excerpt: Easily the most common of America’s large wildlife species, white-tailed deer are often referred to as "overabundant." But when does a species cross the threshold from common to overpopulated? This question has been the focus of debate in recent years among hunters, animal rights activists, and biologists. William McShea and his colleagues explore every aspect of the issue in The Science of Overabundance. Are there really too many deer? Do efforts to control deer populations really work? What broader lessons can we learn from efforts to understand deer population dynamics? Through twenty-three chapters, the editors and contributors dismiss widely held lore and provide solid information on this perplexing problem.

This book was released on 2010 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: White-tailed deer (Odocoileous virginianus ) are an important game animal and provide intrinsic value to many people. However, disease has become of great concern within white-tailed deer populations. Frequency of contract drives the establishment and spread of infectious diseases among susceptible hosts. Supplemental feed provided to increase white-tailed deer survival or create hunting opportunities, as well as bait stations to aid in capture of deer, may increase contact opportunities and disease transfer. The author's objective was to quantify the effects of bait sites on indirect contact between deer. The author examined data from global positioning system (GPS) collars placed on 27 deer near Carbondale, Illinois, USA, from 2002 to 2005. Location data from GPS collars were used to ensure that the author quantified contacts between deer in separate social groups, based on the volume of intersection of their spatial utilization distributions and correlation of movements. Understanding the spatial distribution of white-tailed deer is important to implement effective disease and population management within localized areas. The objective of this study was to measure the home-range fidelity of female deer in an exurban deer herd in southern Illinois.
