Cigarette Butt Disposal Behavior: A Case Study Of A Public Beach On Jekyll Island, Georgia, Usa, Maranda R. Miller, Mark E. Burbach

School of Natural Resources: Faculty Publications

Improperly discarded cigarette butts are a substantial environmental problem. This study explored factors influencing cigarette butt discarding behavior on a public beach on Jekyll Island, Georgia, USA. A mixed-mode design utilized quantitative and qualitative data to study improper cigarette butt disposal. We surveyed smokers regarding their place attachment, environmental attitudes, environmental awareness, and habit as predictors of improper cigarette butt disposal. Environmental attitudes, environmental awareness, and habits were significant predictors of improper cigarette butt disposal behavior. A qualitative inquiry further explored the phenomenon of cigarette butt disposal from the smokers’ perspectives. Interviews illustrated that “improper disposers” experienced themes involving uncertainty …

Spatial variation in landscape composition can influence phenotypic expression in wildlife species and can improve management efforts to express certain phenotypic traits. We evaluated the influence of age, landscape composition, and physiographic province on white-tailed deer (Odocoileus virginianus) antler characteristics using data from 16,622 male deer (age range: 1.5–3.5+ years old) harvested between 1997–2016 across five physiographic provinces in Georgia. Age and physiographic province influenced antler size index (ASI; P < 0.001). ASI of yearling males was greatest (- x = 53.37; SE = 0.39) in the Upper Coastal Plain and least (- x = 46.23; SE = 0.51) in the Lower Coastal Plain physiographic province. Given the differences in ASI among physiographic provinces, we evaluated how landscape composition within each physiographic province influenced ASI of 7,325 yearling (1.5-year-old) males. Yearling ASI was positively related to increasing coverage of cultivated crops and suburban-urban areas (e.g., parks, small housing developments). Conversely, evergreen and deciduous forested cover consistently had a negative effect on ASI, except in the Ridge and Valley physiographic province where evergreen was positively related to ASI. Wildlife managers and hunters should recognize the effects of age, landscape composition, and physiographic province when setting antler size expectations.

Understanding Deer, Bear, And Forest Trends In The North Georgia Mountains: The Value Of Long-Term Data, Andrew R. Little, Gino J. D'Angelo, Charlie H. Killmaster, Kristina L. Johannsen, Karl V. Miller

Most state wildlife agencies collect harvest data to inform management decisions. However, these data are typically considered across relatively short time periods and are rarely revisited. We present a case study using historical records to investigate potential agents (i.e., harvest, predation, and forest change) influencing the declining white-tailed deer (Odocoileus virginianus) population in the north Georgia mountains. We used long-term black bear (Ursus americanus) and deer harvest data, and indices of forest stand conditions from 1979–2015 on eight Wildlife Management Areas (WMAs) in the north Georgia mountains. During 1979–2015, harvest of male and female deer declined by 85% and 97%, …

Landscape Features Affecting Northern Bobwhite Predator-Specific Nest Failures In Southeastern Usa, Susan Ellis-Felege, Shannon E. Albeke, Nathan P. Nibbelink, Michael J. Conroy, D. Clay Sisson, William E. Palmer, John P. Carroll

School of Natural Resources: Faculty Publications

Nest predation is a critical component in avian productivity and typically is the leading cause of nest failure for most birds. Several landscape features are thought to drive the behavioral interaction between northern bobwhite (Colinus virginianus; e.g., nest placement) and their predators (e.g., search methods for food acquisition). In order to understand habitat characteristics influencing predation, we studied bobwhite nests using 24-hour near-infrared video cameras. We monitored 675 bobwhite nests with cameras on 3 properties in northern Florida and southern Georgia, USA, during 2000–2006. To test the association between nest failures and specific failure causes with landscape structure, we calculated …

Population Growth And Mortality Sources Of The Black Bear Population In Northern Georgia, Andrew R. Little, Adam Hammond, James A. Martin, Kristina L. Johannsen, Karl V. Miller

School of Natural Resources: Faculty Publications

An understanding of black bear (Ursus americanus) population trends and cause-specific mortality is needed to direct management decisions in northern Georgia given an increasing human population. Therefore, we evaluated black bear population trends and mortality sources across 26 counties and 18 Wildlife Management Areas in northern Georgia from 1979–2014. We collected harvest data from 6,433 individuals during the study period. Using age-at-harvest data, population reconstruction illustrated an increasing trend in the bear population for both males (λ = 1.113) and females (λ = 1.108). Bait station indices reflected a similar increase in the bear population based on increased …

Habitat Selection Of Wild Turkeys In Burned Longleaf Pine Savannas, Andrew R. Little, Michael J. Chamberlain, L. Mike Conner, Robert J. Warren

School of Natural Resources: Faculty Publications

Frequent prescribed fire (≤3 yr) and selective harvest of off-site hardwoods are the primary restoration and management tools for pine (Pinus spp.) savannas in the southeastern United States. However, a knowledge gap exists in our understanding of eastern wild turkey (Meleagris gallopavo silvestris) habitat selection in longleaf pine savannas and research is warranted to direct our future management decisions. Therefore, we investigated habitat selection of female turkeys in 2 longleaf pine savanna systems managed by frequent fire in southwestern Georgia during 2011–2013. We observed differential habitat selection across 2 scales (study area and seasonal area of use) …

Eastern Wild Turkey Nest Site Selection In Two Frequently Burned Pine Savannas, Andrew R. Little, Nathan P. Nibbelink, Michael J. Chamberlain, L. Mike Conner, Robert J. Warren

School of Natural Resources: Faculty Publications

Introduction: Reproductive success is a critical factor affecting avian demographics and can be influenced by many factors including nesting chronology, predation risk, and fine-scale nest site selection.

Methods: We modeled the relative influences of habitat-related covariates at six spatial scales (nest site: 15-, 40-, 80-, 120-, 160-, and 200-m radii) on Eastern wild turkey (Meleagris gallopavo silvestris) nest site selection in two pine savannas managed by frequent prescribed fire (≤3 years) in southwestern Georgia during 2011–2013.

Results: Nest site (15-m scale) habitat metrics (mean visual obstruction [cm] and canopy closure [%]) had the greatest influence on nest site …

Urban Canada Geese In Georgia: Assessing A Golf Course Survey And A Nuisance Relocation Program, Larkin A. Powell, Michael J. Conroy, Kipling S. Balkcom, Joe Caudell

School of Natural Resources: Faculty Publications

Nuisance complaints about Canada geese (Branta canadensis), have risen in recent years. In Georgia, managers have responded by relocating some nuisance geese to rural areas. During 1993–1996, we used band recoveries of relocated geese to determine the efficacy of relocation as a management strategy. We also used data from a post-card survey of golf courses to monitor the urban subpopulation of Canada geese in Georgia during 1998–2001. Flocks considered by golf course superintendents to be a nuisance were larger (1998: 48.8 geese, 1999: 71.5, 2000: 73.2, 2001: 67.2) than nonnuisance flocks (1998: 13.1 geese, 1999: 16.7, 2000: 25.8, 2001: 18.1). …
