Non Technical Summary
Large mammal conservation and restoration present many challenges to the public, land owners, and wildlife managers. This research focuses on the role of large native mammals in the natural landscapes of the eastern U.S. and the development of recommendations for their conservation and restoration. This work will require a detailed understanding of the current large mammal communities in Kentucky and elsewhere in the southeastern U.S., and an evaluation of the importance of the faunal and landscape changes of the last two centuries relative to the restoration of biodiversity in the region.

Goals / Objectives
1) Examine recently extirpated species and small populations such as the black bear, and reintroduced species such as elk to determine their ecological roles and conservation needs. 2) Develop a predictive model of future colonization patterns for the black bear in Kentucky. 3) Examine the role of the eastern elk in modifying soil processes and succession, and, 4) Assay public opinion regarding the feasibility of carnivore restoration in eastern Kentucky. The human dimension is a particularly challenging aspect of local, regional, and continental biodiversity restoration and conservation biology.
Project Methods
The collection of natural history data representative of the current ecological status of selected species will be collected primarily via the use of radio telemetry, and analyzed using standard analytical procedures (Mech 1983, Kenward 1987, White and Garrott 1990, Kie et al. 1996). These methods will be tailored for individual species, but will follow widely-used protocols. Whenever possible, spatial and behavioral variables will be linked with GIS or other land cover data bases in order to facilitate landscape analyses. To assess the importance of geographical variables and land cover types on radio location distribution, nonparametric correlations (Hollander and Wolfe 1973), regression analysis, and discriminant function analysis as applied by Maehr and Cox (1995) will be used. We will classify available habitat into 5 categories that offer variable resistance to black bear movements: (i) core habitats (primarily forested) that meet all essential black bear life requisites, (ii) habitats that are tolerated by bears but not preferred by resident adults, (iii) habitats subject to high human disturbance, (iv) surmountable barriers that tend to be linear (i.e., roads) and (v) habitats that are avoided to such a degree that they represent insurmountable barriers such as densely populated urban areas (Table1). Accordingly, some highly altered areas (e.g., golf courses, cattle pastures and cemeteries) may provide avenues for successful dispersal although they are insufficient substitutes for natural/semi-natural cover for resident bears (Maehr et al. 1988). Black bear dispersal and colonization potential will be modeled using ArcView GIS and associated analysis extensions following the methodology of Larkin et al. (2004). Grid cells (30 by 30m) representing core black bear habitats, tolerated habitats, areas of high human disturbance and surmountable barriers will be assigned cost values of 1, 10, 50, and 100, respectively. Higher values equate to increased resistance. Insurmountable grid cells will be disqualified as dispersal pathway components. It is important that an accurate sense of local public opinion be obtained to understand their concerns and attitudes relative to large mammal restoration. Survey questions and question format will be designed with input from the University of Kentucky Survey Department, the Sociology Department, and extension faculty in the Department of Forestry. Analyses will follow standard opinion survey methodologies and will follow the guidelines set forth by Mayer and Pratt (1966), Dillman et al. (1974), Christenson (1975), and Heberlein and Baumgartner (1978).

Outputs
OUTPUTS: Large mammal research during this project has focused on the ecology, conservation, and management of large mammals, with most work having been conducted on the black bear in Florida and Kentucky, and elk in Kentucky. Additional work included ecological investigations of bison in Yellowstone and panthers in Florida. We have conducted thousands of hours of field research in conjunction with state and federal wildlife, conservation, and natural resource agency professionals, non-profit organizations, private individuals, students at the University of Kentucky and abroad. These data and associated research findings have been important for applied management of several large mammals and ecological communities. In addition we have spent thousands of hours analyzing data, creating models, and preparing documents for dissemination to the scientific community and general public. Finally, through teaching and extension outlets on and off campus, our research has served as important class-room examples of wildlife science and created field-based learning opportunities for nearly 400 undergraduate students and a dozen graduate students in the natural resource or biological sciences at the University of Kentucky or elsewhere, and nearly 500 students in elementary schools in the state. The research has also served as an informational springboard in creation of 4 new graduate courses (3 seminars, and a field-based series course). Through television, magazine, and other media interviews our large mammal research projects have drawn considerable positive attention and reached audiences at multiple scales, from local outlets to TV viewers across the globe. Our field-based research has road-tested new technologies (e.g. GPS collars, cell-phone based transmission of animal location data, non-invasive genetic studies) and evaluated their efficacy, cost-effectiveness, and limitations for use in large mammal studies. Some of these technologies have later been adopted by wildlife professionals. The data generated from these studies in their many forms (animal location data, maps, models) have been used by our collaborators and funders to help make science-based decisions about said species. As such, we have developed important collaborations and productive relationships with a number of natural resource agencies, NGOs, private individuals, and other academic institutions, that have ultimately resulted in the leverage of a number of research grants. In addition, our work has led to the development of conceptual models that have increased our knowledge and understanding of community ecology. PARTICIPANTS: Phil Crowley and David Weisrock, UK Biology, (co-investigator on bear and bison projects); Songlin Fei, Chris Barton, and Mike Lacki, UK Forestry, (co-investigator on some aspects of elk, bear, and panther work); David Chambers, University of VA-Wise (co-investigator on bear parasite study); P.J. White, Glen Plumb, Rick Wallen (and others) from National Park Service (co-investigators on bison project); Steven Dobey, Karen Alexy, Tina Brunjes, Jayson Plaxico, Jon Gassett, Mike Strunk, Dan Crank, Will Bowling, and Charlie Logsdon, KY Dept of Fish and Wildlife Resources (co-investigators on elk and bear projects in KY, coordinators for state grants and administration); Tom Toman, Rocky Mountain Elk Foundation (grants administration on elk project); Claire Martin, Disney Worldwide Conservation Fund, (grants administration on FL black bear project); Steve Bakelitz and Jenny Beeler, National Park Service (coordination of projects and chief contacts); Hilary Swain, Archbold Research Station (director of field station; coordination and logistical support of field efforts on FL bear project; Jeffery Larkin, Indiana University of Pennsylavania, (co-investigator on elk and bear projects); Tom Hoctor, University of Florida (co-investigator on some aspects of FL bear work); Joe Duchamp, Indiana University of Pennsylavania, (co-investigator on some aspects of elk work); Walt McCowan, Mike Orlando, Florida Fish and Wildlife Conservation Commission (assistance with field efforts on FL bear project); Smoak family, Hendry family, and Kerry Lightsey, local property owners in Highlands County, Florida, (assistance with property access and logistical support on FL bear project); 14 graduate students worked on various portions of these projects and received professional development and training opportunities, including 12 graduate degrees earned; at least three dozen technicians and 8 undergraduate students have worked on various components of all these studies and received development and training opportunites. TARGET AUDIENCES: Using written and electronic publications, social media outlets, workshops, oral presentations, and opportunities for volunteerism during field research, dissemination efforts were made to reach the following audiences: scientific community in wildlife sciences, ecology, forestry, natural resources, and conservation biology; graduate, undergraduate students; ranchers, citrus growers, and other agricultural stakeholders impacted by study animals; general public. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
Our findings have led to important changes in management, conservation, and land planning in several places in the U.S. Our black bear research has led to the development of strategies to ameliorate further development impacts on the species in southcentral Florida and helped delineate the proposed boundary of a new national wildlife refuge designed to protect the headwaters of the Everglades. Our analyses of these bear data have led to the creation of a road-crossing model designed to inform transportation officials about areas of high road strike risk to bears in this relatively small population. In this area we also successfully partnered with a number of cattle ranchers, NGOs, local government officials, and a biological research station to identify information that has helped lead to science-informed educational and planning strategies to help bears, ranchers, developers, and private citizens better co-exist. In addition, studies on bears within a palm-feeding guild in this area have led to new synthetic findings regarding intraguild mutualism. In Kentucky, where bears have only recently recolonized eastern portions of the state, our bear research has led to improved understanding of human-bear relations, particularly with regard to the conditioned behaviors of nuisance bears. Research in the Commonwealth has also provided important information on bear population size that has informed harvest strategies for the species which given its small population size remains at high-risk of overharvest. In particular here (and in FL) our bear work has road-tested the efficacy and cost-effectiveness of new GPS and cell-phone collar technologies to remotely locate animals and gather data. These data have yielded new insight into resource use and movement patterns of bears (and elk) of interest to wildlife managers and land planning organizations interested in landscape-scale ecological connectivity. In Yellowstone National Park, our work has provided important insight into the effects that selective culling may be having on overall herd immunity to and spread of brucellosis, which in-turn, has increased the call for alternative strategies to deal with this management issue important for conservation and the agricultural economy outside the park. Results from the FL panther research has helped improve our knowledge base about resource use and potential impacts of extractive activities on these endangered cats, and through predictive modeling, how they may be impacted from continued urbanization and climate change-caused sea level rise. Our elk research has yielded important information on the largest herd of megaherbivores in the eastern U.S. Our pioneering use of infrared technologies to study and model elk numbers in Kentucky led to refinement and recalibration of existing population models. In addition, studies of elk have yielded important insight into how this large deer species is impacting the landscape, particularly at sites that are degraded and/or fragmented such as reclaimed mines. Finally, our efforts have led to initiation of a study on the most difficult to monitor age-gender class of elk, adult bulls.

Outputs
OUTPUTS: Large mammal research in my lab continues on the ecology, conservation, and management of large mammals, with most work focused on the black bear in Florida and Kentucky, and the elk in Kentucky. We continue to focus on the ecological role of both species, their interaction with human societies, and each species unique management and conservation needs. With renewed state funding, we have expanded our research on bears in Kentucky to include population ecology studies in an additional area. Additionally, we continue to monitor a number of female bears in southeast Kentucky to examine differences between nuisance and non-nuisance individuals, and the impact of that behavior on survival, resource use patterns, and fecundity. Bear research in both areas were the subject of 2 poster and 2 oral presentations at the state and national chapter annual meeting of The Wildlife Society. In addition, our bear research was the subject of a television segment on WLEX news in Lexington, KY, and a longer segment on Kentucky Afield, a popular program on Kentucky Education Television. At least two newspaper articles in McCreary County also focused on our bear research. In Florida, we received state funding to conduct a 3-year population study of bears in Highlands and Glades Counties subsequently initiated in summer 2010. In addition, we received additional GPS data from 3 radio-collared bears from a highly urbanized area of central Florida that identified potential pathways that land managers and other stakeholders can use to help maintain ecological connectivity for bears and others species in this highly biodiverse region. The bear research in this area was the subject of a book on Florida's cattle ranches and an upcoming article in Audubon magazine. The bear research is a popular and important topic of classroom discussion in several natural resource courses here at the University of Kentucky, as well as a field-based opportunity whereby undergraduate and graduate students can get hands on experience in researching large mammals and better understanding the issues surrounding bear management and conservation. In eastern Kentucky we received a 2-year grant to initiate a demographic study of bull elk, one of the more difficult population segments to study that is also the most economically valuable for local hunting-based tourism in an historically economically impoverished region. This and past work on elk were the subject of an oral presentation and published paper for a regional forestry meeting that examined the issues surrounding this growing elk population and its potential ecological and sociological implications. An article appeared in Highlights kids magazine that showcased what it was like to work on our elk project. Finally, work being conducted by a doctoral student (shared with another principal investigator here at UK) has resulted in a better understanding of brucellosis infection in bison in Yellowstone National Park, and one peer-reviewed published paper so far. This work continues as a collaborative project between the University of Kentucky and the National Park Service. PARTICIPANTS: Individuals: Principle investigator of all projects: John J.

Impacts
Our research findings have impacted a variety of stakeholders within Kentucky and beyond. Detailed GPS-based movement data have provided a foundation for new analytical approaches that is changing the way black bear and other large mammal telemetry data are collected, interpreted, and analyzed. These intensive data sets have allowed us to begin to analyze telemetry data using more modern analytical approaches that should yield a more accurate representation and further our understanding of certain aspects of animal ecology, such as movement and resource use patterns. We continue to refine our understanding of the limitations and potential applications of these GPS data. The use of the text message-based data transmitting technologies in these new collars clearly indicate their advantage over more manually intensive location and data recovery procedures. Our research findings continue to inform both professional and public audiences about these ecologically and economically important large mammal species, as manifested in articles and program segments that appeared in a variety of media outlets this year. Research on black bear in both Florida and Kentucky have provided important demographic, resource and habitat use, and movement data valuable to and used by wildlife and other natural resource managers and land stewards. Our black bear and elk research in Kentucky continues to help guide state wildlife managers with important decisions on these species that is often informationally transferred to the general public though a variety of mechanisms. In south-central Florida, our black bear data has been used by local land planners to inform short and long-term land planning, as well as by the state wildlife agency for management of the species. We continue identifying important core and dispersal habitat for the imperiled bear population in south central Florida, including locations bears use to cross highways and thereby maintain demographic connectivity. The bear and elk research are popular and important case studies of large mammal management and conservation used for classroom discussion and field trips in several natural resource courses here at the University of Kentucky. Students of a variety of ages and the general public are eager to learn more about the charismatic elk and bear through our dissemination of research findings, particularly when educational outlets allow direct observations of these species. Such opportunities can and have motivated students and the members of the public to pursue studies in natural resource management, stimulated additional inquiry into the natural world and sustainability, and encouraged thinking about our role in the natural world. It's likely that the Highlights Magazine article on our elk research probably reached millions of grade school children. The management of Yellowstone bison is one of the most controversial topics in the conservation and wildlife communities. Findings from our research are informing future decisions that will likely have a major impact on bison management, including vaccination and culling of individuals outside Yellowstone National Park.

OUTPUTS: We continue our research on reintroduced elk and recolonizing black bear in Kentucky, and a dwindling population of black bear in southcentral Florida. In addition to the initial project objectives, research was conducted on the effects of sea level rise on black bear and panther in Florida, and consulting work was provided that examined the potential impacts of oil and gas development on the Big Cypress ecosystem in Florida. As elk in Kentucky have grown to nearly 11,000 they have come into conflict with humans throughout the restoration zone and remain difficult to survey, a topic of presentations given at an international conference in China (Annual Conference of the Society for Conservation Biology) and 2 invited talks (Indiana University, Alice Lloyd College). Although funding from the state wildlife agency was not renewed for the elk project in 2009 (due to internal competition for these funds within the agency), we continued to monitor 5 GPS collared elk and stockpiled an additional 12 collars in anticipation of funding in 2010 that will allow examination of adult bull elk demographics and resource use patterns. The relatively new GPS technology we use allows researchers to either download stored GPS data from a close distance, or to have it transmitted via cell phone signal to a centralized computer. Our findings continue to indicate that this new technology provides superior reliability to traditional vhf telemetry and older store-on-board GPS units. Analytical consulting was provided to a graduate student researching PA elk at Indiana University of Pennsylvania (1 completed Masters thesis). Finally, a 3-year study of elk-parasite relations in Kentucky revealed the transplacental transmission of antibodies to a potentially life-threatening parasite, the meningeal worm (1 completed Masters thesis). We are also continuing our research on the ecology of black bears in southeastern Kentucky and southcentral Florida. In 2009 we captured and radio-collared an additional 34 bears in Kentucky and 3 in Florida. Most bears were equipped with GPS collars, including some with said cell-phone transmittable data. In both bear studies, we are currently analyzing resource selection and movement patterns, including bear-road relationships in Kentucky (1 completed Masters thesis), identification of critical road crossing corridors in Florida, the efficacy of select GPS collar models (1 completed Masters thesis), and the effects of bear nuisance behavior on fitness. We initiated a funded study of black bear genetics in Kentucky that has yielded nearly 200 hair samples that will inform us of population structuring and relative influence of bears from neighboring states in contributing to Kentucky's recolonizing bear population. Finally, work was concluded on a model that examined the potential impact of sea level rise on Florida panther and black bear (1 completed Masters thesis). Our target audiences for dissemination of research findings included natural resource professionals, UK students, land stewards and planners, local government officials, private land owners, and non-governmental organizations.

Impacts
Our research findings have impacted a variety of stakeholders within Kentucky and beyond. Detailed GPS-based movement data have provided a foundation for new analytical approaches that is changing the way black bear and other large mammal telemetry data are collected and interpreted. These findings continue to inform both professional and public audiences about these ecologically and economically important species. Research on black bear in both Florida and Kentucky have provided important demographic, resource and habitat use, and movement data valuable to wildlife and other natural resource managers and land stewards. For example, wildlife managers in KY suspect that elk are nearing regional social and ecological carrying capacity but data on species abundance and distribution were lacking until our forward looking infrared survey (1 draft manuscript) and analytical model was used by the state wildlife agency to adjust elk harvest limits and population models and to delineate hunt boundaries for 2009. Our black bear research informed state wildlife managers in their decision to cautiously proceed in 2009 with Kentucky's 1st bear hunt. Our continued black bear den work is providing insights into the impacts of nuisance behavior on fitness of this recolonizing population. The black bear in southcentral Florida is an important flagship and umbrella species for the many lower profile, less charismatic threatened and endangered species that inhabit the unique sand scrub of the Lakes Wales Region. We continue identifying important core and dispersal habitat for the imperiled bear population in south central Florida, including locations bears use to cross highways and thereby maintain demographic connectivity. Local government officials in Highlands County, FL and regional land stewards are currently using our bear data to inform development plans in ways that reduce impacts on bears and other species that use similar habitats - the subject of a workshop we hosted at Archbold Research Station in December. In addition to these applications, we work with a number of local cattle ranchers to help them understand the impact of their land management practices on black bears and other species. Findings from the Florida panther-black bear sea level rise model is likely to influence a number of stakeholders in that area and lead to actions that seek to mitigate the effects of inundation on these 2 species and others sympatric within their range. A science-based understanding and appreciation for the black bear and elk will strongly influence educational efforts and concomitant public perceptions about the species in ways that reduce human-wildlife conflict and that promotes species viability. For example, our black bear and elk projects and related GPS-cell phone and tracking technological applications was the subject of a presentation to nearly 300 Rowan County, KY middle school science students in November. In addition, the Florida black bear project reached perhaps millions of people via a television segment that aired on CNN (http://www.cnn.com/2009/TECH/09/07/florida.tracking.bears/index.html ).

OUTPUTS: Given their high visibility and real or perceived risk to humans and associate resources, the restoration, management, and conservation of large mammals pose daunting challenges. Research during the 20th century has increasingly shown that large mammals can have profound impacts on ecosystem processes and components that influence human society in various direct and indirect ways. These effects are increasingly evident as we continue our research on reintroduced elk and recolonizing black bear in Kentucky, and a dwindling population of black bear in southcentral Florida. Nearly a decade after reintroduction, elk numbers are now approaching those of Yellowstone National Park. As such, elk have increasingly come into conflict with humans throughout the restoration zone. Managers suspect that elk are nearing local social and ecological carrying capacity in the area but data on the species abundance and distribution have been lacking. Elk are notoriously difficult and expensive to accurately survey, and grossly inaccurate population estimates can lead to prolonged under or overharvest that threaten local ecosystems or population viability, respectively. This year we concluded a grant funded study that used forward looking infrared technologies to survey and model elk abundance and distribution in the restoration zone, findings currently being used by the state wildlife agency to adjust elk harvest limits and population models, as well as to delineate hunt boundaries. In 2009, our research will shift towards examining the efficacy of various treatments in deterring nuisance elk behavior, and evaluation of changing public attitudes towards elk nearly a decade post-reintroduction. We also concluded pilot studies that evaluated a new global positioning system (GPS) collar for both elk and black bear. This new technology allows researchers to either download stored GPS data from a close distance, or to have it transmitted via cell phone signal to a centralized computer. Our findings indicated that this new technology provides results superior to traditional vhf telemetry and may be more cost efficient despite higher initial costs. We are also continuing our research on the ecology of black bears in southeastern Kentucky and southcentral Florida. In 2008 we captured and radio-collared an additional 19 bears in Kentucky and 6 in Florida. Most bears were equipped with GPS collars, including some with said cell-phone transmittable data. In both bear studies, we are currently analyzing resource selection and movement patterns, including identification of critical road crossing corridors in Florida. Finally, in late 2008 we initiated a funded study of black bear genetics in Kentucky that should inform us of population structuring and relative influence of bears from neighboring states in contributing to Kentucky's bear population. Finally, as the elk research has already done, ecological and sociological studies of the black bear in eastern Kentucky and Florida will not only promote regional conservation, but will inform our general knowledge of this important species and large mammal conservation and management in general.

Detailed GPS-based movement data are providing a foundation for new analytical approaches that is changing the way black bear and other large mammal telemetry data are collected and interpreted. These findings continue to inform both professional and public findings and perceptions of these ecologically and economically important species.

A science-based understanding and appreciation for the black bear and elk will strongly influence educational efforts and concomitant public perceptions about the species in ways that reduce human-wildlife conflict and that promotes species viability. In addition, population data on these 2 species are critical to state wildlife managers tasked with establishing sustainable harvest limits and satisfying a variety of affected stakeholders.

OUTPUTS: Large mammals in the southeastern U.S. evolved as communities within complex networks of competitive and trophic interactions. However, these interactions, especially those of predators and their prey, are seldom well-understood, and they can exhibit great regional and temporal variability. In many cases, competition has been obscured by millennia of successful niche separation, or the "ghost of competition past". One of the challenges in restoration ecology is the maintenance and re-creation of interspecific relations that existed before European settlement of North America - relations that have been obscured by two centuries of anthropogenic transformation. In the southeastern U.S., dramatic ecological changes have resulted in new relations among wild animals and their landscapes. A thorough understanding of existing patterns in large mammal distribution and ecology will be necessary to evaluate the effectiveness and consequences of future restorative efforts, and in facilitating successful biodiversity conservation. The results of this study will also be important to the growing eco-tourism industry in eastern Kentucky. As interest in the eastern Kentucky bear populations grows, the results of this study will become increasingly important to local and regional education efforts. A fact-based understanding and appreciation for the black bear will promote responsible human behavior in occupied black bear range including the urban-wilderness interface where otherwise wary and wild individuals may be encouraged to utilize food sources of human origin. Given the success of elk restoration over the last 10 years, a comparable increase in the black bear will result in the desire of some members of the public to utilize this species as legal game. A thorough understanding of black bear habitat relations, spatial patterns, behavior, and demographics will be critical in the development of sustainable harvest strategies. The inclusion of the public through mail surveys and other contacts will promote partnerships between government entities and the public that will foster successful wildlife conservation programs. Finally, as the elk research has already done, ecological and sociological studies of the black bear in eastern Kentucky will not only promote regional conservation, but will serve as national and international models. Expanding or restored populations of large mammals create unique challenges for local residents and government stewards of natural resources. The insights derived from this work will enhance the likelihood of compatibility among large carnivores, large mammals, and humans. Intensive data collection continues on about 40 black bears in Kentucky and Florida. Elk were recently instrumented with GPS collars to record movements related to dispersal and colonization.

Impacts
The ecological study of the black bear has provided important information to managers regarding future colonization and population growth potential. The black bear has the potential to drive a productive recreation-based economy in this economically challenged region. Our sociological work has the potential to improve the public perception of this large carnivore and help restore biodiversity and ecological sustainability. The implications of our elk research will help fine-tune management for this recently established herd that is already an important economic benefit to the region. Understanding the balance between elk abundance and impacts to soils and the landscape will help maintain the ability of the region to support this economically important resource, and will help educate the public and natural resource agencies. The bear work in Florida is identifying important core and dispersal habitat for the imperiled population in south central Florida. Detailed movement data are providing a foundation for new analytical approaches that will change the way black bear telemetry data are collected and interpreted.

We captured 42 elk calves. About 10% of the calves died as neonates; all but one mortality was linked to canid predation. None of the collared calves died during this reporting interval. From October 2005 -September 2006, approximately 5,000 locations were collected on the elk from last year's capture efforts and the calves caught in 2005. Most (59%) of the locations were in grassland, 19% in forest, 7% in shrub scrub, 3% in forest/field edge, 13% in unspecified habitat and 1% in other habitats such as bare ground, active mines, and roads. From December 2005-June 2006 we immobilized 27 of the calves caught in 2005. Eight of the original calf collars came off the animals, 1 of the animals died, and we were unable to immobilize 7 of the calves. We also immobilized 5 of the calves captured in 2004 to obtain blood samples and measurements; we were unable to dart the 4 remaining animals from this cohort. The serum samples assembled through these efforts are being tested to determine the rate of meningeal worm infection within the population. We captured 25 black bears and radio-collared them (1 November 2005-August 2006). 15 received radio collars for the first time. Five were captured as nuisance animals. One bear captured in Pike County, Kentucky had a West Virginia ear tag. Four hundred and twenty aerial and 5,612 GPS locations were obtained on 33 bears. They were found in hardwood forest (78.5%), and on steep slopes (70.5%) with a southerly aspect (45.9%). Annual home ranges for bears with at least 20 locations were calculated (n=11). The average home ranges using 90% adaptive kernel and 99% minimum convex polygon analyses were 40.69 km2 (S.E. = 23.22) and 29.28 km2 (S.E. = 16.22) for females (n=6) and 359.86 km2 (S.E. = 120.03) and 277.7 km2 (S.E. = 65.56) for males (n=5). Males had larger home ranges than females using both adaptive kernel (p = 0.029) and minimum convex polygon (p = 0.011) methods. Nine dens (5 female) were located from December 2005 through March 2006. Five females gave birth to at least 14 cubs. We continued our analysis of the Kentucky Department of Fish and Wildlife Resources black bear database. Since 1987, a minimum of 122 non-cub black bears have been handled in the state, dead or alive. Ninety-six were male, 19 were female. Average age was 2.9 years (S.E. = 0.26) (n=61). Most (90%) first-time bear handlings occurred in counties bordering West Virginia, Virginia, Ohio, or Tennessee. The Kentucky black bear population appears relatively small, young, and recolonizing. We are also examining how the presence of the black bear near the Kentucky towns of Cumberland, Benham, and Lynch, affects area residents and how their views may affect bear colonization. Using interviews and surveys, we explored the motivations and interests of people who visit Kingdom Come State Park to see bears and their perceptions about wildlife. Using microsatellite DNA analysis we are examining kinship and dispersal patterns of black bears in Kentucky and their probable genetic origins. Initial results are consistent with recolonizing populations elsewhere and indicate that many of the bears in Kentucky originated in West Virginia.

Impacts
This research is important in understanding the ecological relations between colonizing large mammals and their environment in a landscape that has been without them for more than a century. Such information is important in devising long-term management strategies and providing direction for short-term adaptive management that promote ecological restoration and acceptance by the local human population. We expect that the black bear and elk will continue to increase in conservation and tourism value as both populations grow and as the public becomes more aware and appreciative of the services both species provide.

We captured 24 black bears from 1 Nov. 2004 to 6 Aug. 2005. They were monitored from 1 Nov. to 31 Oct. 2005 in Letcher, Harlan, Bell and Pike counties in SE Kentucky. 420 aerial locations were obtained on 25 bears. They were found in hardwood forest (88.1%) and steep slopes (78.8%) with a south aspect (44.8%). Mean annual home ranges for bears with at least 30 locations using 99% fixed kernel and minimum convex polygon analysis was 42.15 km2 (S.E. = 2.91) and 27.43 km2 (S.E. = 1.39) for females (n=3) and 292.57 km2 (S.E. = 39.11) and 157.1 km2 (S.E. = 27.19) for males (n=3), respectively. Males had larger home ranges than females. 6 winter dens (2 female) were located. One female had 4 cubs and the other had 3 cubs. 19 dens located since 2003 were on steeper slopes (p = 0.017) in forests with a lower overall DBH (p=0.03) and had higher densities of rhododendron (p=0.01) and mountain laurel (p=0.02) than random sites. Since 1987, 105 black bears (86 males) have been handled in the state, with an average age of 2.8 years. 91% of captures were in counties bordering WV, VA or TN. These data suggest that the Kentucky population is small, young, and in the process of colonizing. Artificial foods bring bears into conflict with humans and may change bear distribution and behavior. At least 55% of study animals have a history of nuisance behavior. Human conflict with the bear may increase negative sentiment and make the public resistant to its restoration. We are examining how black bear presence near Cumberland, Benham, and Lynch affects area residents and how their views may affect its return. We are also exploring the motivations and interests of the people who visit Kingdom Come State Park and the ways artificial foods and attractants change bear behavior in the region. Genetic analyses will help us understand kinship and dispersal of black bears and their probable geographic origins. Initial results are consistent with recolonizing populations elsewhere and indicate that many of the bears in Kentucky originated in West Virginia. Elk in E Kentucky affect ecosystem processes in a landscape of reclaimed grasslands and forest remnants. Here, elk use forested ridge-tops for resting and ruminating. These locations have sparse or absent leaf litter, trampled and diminished vegetation, large deposits of dung, and urine-saturated soils. Disturbed ridge-tops had higher soil ammonium (0.68 mg/kg, 10-20 cm) than reference sites (0.25 mg/kg) in spring 2004 and lower ammonium (0.72 mg/kg, 0-10 cm; 0.44 mg/kg, 10-20 cm) than reference sites (1.80 mg/kg, 0-10 cm; 0.94 mg/kg, 10-20 cm) in summer 2004. Total carbon was higher inside (67.57 g/kg, 0-10 cm) than outside (45.38 g/kg) of ridge-top exclosures in fall 2004. Soil moisture, litter depths, and vegetative cover were generally lower, while % bare ground was higher on disturbed ridge-tops. Sediment averaged 2.21g/m2 inside exclosures, 2.86 g/m2 outside, and 0.39 g/m2 on reference ridge-tops. The lack of predators such as the wolf or cougar likely contributes to habitual elk use of ridge-top forests. Such concentrated use may promote the colonization of plant species including rare natives and invasive exotics.

Impacts
The ecological study of the black bear has provided important information to managers regarding future colonization and population growth potential. The black bear has the potential to drive a productive recreation-based economy in this economically challenged region. Our sociological work has the potential to improve the public perception of this large carnivore and help restore biodiversity and ecological sustainability. The implications of our elk research will help fine-tune management for this recently established herd that is already an important economic benefit to the region. Understanding the balance between elk abundance and impacts to soils and the landscape will help maintain the ability of the region to support this economically important resource, and will be the foundation for the development of information to educate the public and natural resource agencies.
