Available in PDF, EPUB and Kindle. Book excerpt: White-tailed deer (Odocoileus virginianus) have considerable impacts on woody and herbaceous vegetation. Many oak-hickory forests in the eastern U.S. are experiencing a lack of oak (Quercus) and hickory (Carya) regeneration, with deer being a likely culprit. Furthermore, few have studied deer use of different herbaceous food plot mixtures. I addressed these gaps in the literature by assessing deer impacts on forest and herbaceous vegetation in southern Illinois. I established 150 paired plots (enclosed and control) in June 2015 and measured 25 habitat variables to assess impacts of deer herbivory from August 2015 to August 2016. Oak seedlings were present more often and in higher numbers within enclosed plots (F1,299 = 6.25, P 0.050 and F1,387 = 4.50, P 0.050, respectively). There were no differences in the height of oak seedlings or the presence, number, or height of hickory seedlings in enclosed versus control plots (F1,53 = 0.010, P = 0.938; F1,299 = 0.850, P = 0.357; F1,267 = 1.16, P = 0.282; and F1,15 = 0.030, P = 0.855; respectively). During September-November 2015, I counted and marked fallen acorns within 50 random paired plots; the number of acorns discovered or lost did not differ between enclosed and control plots (F1,94 = 0.310, P = 0.578 and F1,8 = 0.120, P = 0.736, respectively). I suggest managers incorporate potential deer impacts when designing management plans to best encourage oak regeneration. During September-November 2015, I established 16 food plots (half tilled; each 0.05 ha in size), planted to 4 food plot types. I compared Big Tine Buck Brunch, Evolved Harvest Throw & Gro, Antler King No Sweat, and a food plot mixture that I created. I measured deer use via 2 methods: vegetation growth in exclosures versus control (i.e., unfenced) areas and camera traps. Deer used all 4 food plot mixtures (n = 292 - 2,522 pictures/plot over 9 weeks), having a negative impact on mean vegetation height outside of exclosures (F3,1148 = 6.71, P

Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the ecology and behavior of white-tailed deer (Odocoileus virginianus) is necessary for proper conservation and management, especially in the face of emerging infectious diseases. The objectives of my study were to estimate juvenile survival, compare methods of quantifying contact rates (simultaneous GPS locations vs. proximity loggers [PLs]), and investigate the impact of group depopulation on contact rates of remnant adult female and juvenile deer. To achieve these goals, I captured, radiotracked, and monitored adult female and juvenile white-tailed deer in southern Illinois during 2011-2014. Survival analysis of juveniles revealed that main causes of mortality were capture related and predation, though some dead animals also showed signs of hemorrhagic disease. Comparison between simultaneous GPS locations and PLs showed evidence that deer coming within the general vicinity of each other are less likely to come in close contact if they are in neighboring social groups than deer whose home ranges overlap little, if at all. Finally, experimental removal of group members caused few if any remnant adult females to alter their contact rates or space-use, but caused remnant juveniles to have lower space-use fidelity compared to control deer and to increase their direct contact rates with other groups temporarily. Using these results, I discuss the large effects that severe weather events can have on juvenile survival, the importance of social structure on the potential transmission of disease agents among female and juvenile deer, and the difference between adult females and juvenile deer in their need for social interactions. My research provides ecologists, wildlife biologists, and managers with valuable information concerning the potential impacts of the environment, infectious diseases, and management strategies on white-tailed deer populations.

Available in PDF, EPUB and Kindle. Book excerpt: Many natural resource agencies are managing white-tailed deer (Odocoileus virginianus) populations in suburban areas and require information about deer populations, deer impacts on vegetation, and human preferences toward deer and deer management to support decision making. The author's study, based in the Chicago Metropolitan Area during 2007-2011, utilized a multi-faceted approach to investigate common obstacles in suburban deer management. In these findings, the author discusses the need for managers to examine suburban deer populations and management issues at a broader scale (i.e., countywide versus single community) and the promotion of proactive deer management in lieu of the conventional paradigm of beginning management only when deer populations have become overabundant. Discussion topics include practicality and costs of deer density estimation and herbivory monitoring techniques over multiple plant communities and numerous study sites. In addition, the author illustrates how a comprehensive human dimensions survey can identify determinants that contribute to the public's perceptions of deer density and assess the acceptability, conflict, and beliefs regarding deer management methods. Lastly, the author describes the relationship between landscape characteristics and deer density; this information can be utilized to determine suburban lands that may be prone to high deer densities and inform land management practices. The author's work provides suburban natural resource managers with techniques to identify management practices supported by their public constituents and information useful for managing deer populations.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given that overabundant white-tailed deer (Odocoileus virginianus) can exert lasting negative effects in forested ecosystems, management of deer has been a foremost conservation concern in eastern North America since the last century. Although knowledge of density impacts on body mass, pregnancy rates, and forest regeneration are vital for deer management, relatively few studies have assessed these relationships in the same study area for a >5-year period. I took advantage of a managed culling program to investigate the impacts of deer density on body mass, pregnancy rates, and native forest understory and trillium (Trillium grandiflorium) regeneration at Cuyahoga Valley National Park (CUVA), Ohio, during 2016-2022. Deer densities were estimated using distance sampling in November and deer were culled by sharpshooters the following January-March. Each deer culled was aged, sexed, weighed, and inspected for fetuses (recorded as present or absent). Deer densities ranged from 8.6-18.0 deer/km2 and deer removed each study year varied between 205 and 450. Concurrently, the 1-6 tallest native seedlings per genera per subplot were measured in July-August in 25 fenced and unfenced paired plots and in long-term ecological monitoring (LTEM) plots. Browse was estimated in unfenced paired plots in alternating years. Trillium stem heights in both unfenced controls/fenced exclosures and browse in unfenced control plots were collected in April-June each year. Using a linear mixed model (LME), I analyzed change in body mass of culled deer and found a significant negative relationship with current deer density (P
