Non Technical Summary
Land ownership patterns in forested areas of the southeastern U.S. are in a period of dramatic change. Human populations are expanding, per capita consumption of natural resources is increasing, and the popularity of low density rural housing is causing remaining contiguous natural habitats to be progressively fractured into smaller and smaller fragments. These changes have negative impacts on wildlife dependent upon forested areas not only through direct loss of habitat, but also through decreases in the quality of remaining habitat, as the natural disturbance regimes to which these ecosystems are adapted become increasingly disrupted with the shrinking size of remaining habitat fragments. These changes in land use patterns elevate the importance of plantation forests in providing habitat for wildlife. However, decreases in the market value of domestic wood products have prompted many private industrial forest companies in the southeast to sell land previously used to produce timber products to residential and commercial developers, resulting in additional loss of forested habitat. Radical changes in management practices on land that remains in timber production in the southeast are predicted in the near future, as rising fuel costs and consequent increases in the desire to decrease foreign dependence on oil have resulted in considerable interest in domestic production of biofuels. Woody biomass production is predicted to be particularly popular in the southeast where environmental conditions are conducive to rapid growth rates in vegetative species that could be used for woody biofuels. A shift from production of more traditional timber products to woody biomass is likely to cause an intensification of silvicultural practices and also conversion of plantations from native tree species to non-native energy crops that have high growth rates. In other parts of the country there is concern that woody biomass plantations may provide habitat more similar to agricultural croplands than to natural forests, but to date no peer-reviewed research has investigated these issues in the southeast. Collectively, these changes in land use and changes in forest management practices are likely to have negative effects on biodiversity of forest wildlife. Development of effective conservation strategies for forest wildlife will require better understanding of fundamental wildlife habitat relationships so that accurate predictions can be made regarding wildlife response to anthropogenic disturbances. Research on the mechanisms that influence biodiversity in forests will be crucial to the identification of forest management practices that promote habitat for a variety of wildlife species. As human populations grow and as natural forested habitat becomes increasingly scarce across southern landscapes for the reasons outlined above, human-wildlife interactions and conflicts are likely to increase in frequency. Consequently, strategies proven to reduce human-wildlife conflicts will become an invaluable tool for wildlife managers. Studies aimed at identifying tactics that can reduce human conflicts with wildlife thus deserve high priority.

Goals / Objectives
The overarching goal of this umbrella project is to gain a better understanding of how wildlife respond to human alterations of forested habitats. Sub-projects will investigate three broad topics. First, a number of sub-projects will examine changes in abundance, distribution, and species diversity of wildlife in response to forest management practices in Florida and other southeastern states. Second, several sub-projects will assess the impacts of human activities in non-forested habitats on wildlife that utilize neighboring forests. Finally, a number of sub-projects will identify management practices capable of reducing conflicts between humans and forest wildlife. Each subproject will have distinct methodology, developed to achieve the specific objectives of that particular investigation.
Project Methods
Objective 1 - Impact of forest management activities on wildlife. Sub-project A: The impact of pine straw raking on terrestrial invertebrates will be ascertained using a randomized complete block design. Three stands of each of 3 species of pine will be split in half, and each half either raked annually or left untreated. Invertebrates will be sampled once per month during year 1 and once per season during year 2-4. To our knowledge, this is the first study to assess the effects of pine straw raking on fauna. Results will determine whether raking causes changes in biological cycles important to proper ecosystem functioning. Sub-project B: The influence of prescribed burning on bats will be assessed in longleaf pine stands with 3 different burn histories. Nocturnal insect communities and local vegetation will be sampled during 2 summers, and an information-theoretic approach will be used to determine the factors most closely associated with bat activity. Results will be of interest to those who use prescribed burning to increase biodiversity. Sub-project C: The impacts of upland restoration on wild turkey will be investigated using radio-telemetry of female turkeys to determine relative use of restored versus untreated areas during pre-nesting, nesting, and brood-rearing periods. Local and landscape characteristics of used sites will be identified, and associations will be determined between these factors and nest success and brood survival. Objective 2 - Impacts of human activities in non-forested habitats on animals that utilize neighboring forests. Sub-project D: The status of gopher tortoises on private lands in Mississippi will be determined by examining factors associated with the distribution of remaining tortoises. Mail surveys will be used to ascertain land use practices and tortoise occurrence and GIS data will be used to assess land use change. Results should increase understanding of the species distribution so that steps can be taken to reduce further habitat loss that could result in an uplisting of the species to endangered. Objective 3 - Developing strategies that minimize human-wildlife conflicts. Sub-project E: Animal behaviorists, entomologists, and chemists will work together to isolate chemical substances that promote attraction or repulsion in the invasive nine-banded armadillo. Wild-caught animals will be maintained in captivity to determine relative interest in materials expected to elicit either interest or revulsion. The chemical composition of the materials that elicit the strongest, most consistent reactions will be determined, and development of a bait or deterrent will be considered. Sub-project F: Horticulturalists and wildlife biologists will work together to identify native annuals and perennials resistant to damage from white-tailed deer. Selected species will be planted in replicates within and outside enclosures that exclude deer, and measured every two weeks throughout the growing season to assess damage caused by deer. Results should reduce the probability and severity of negative interactions between wildlife and humans.

Impacts
What was accomplished under these goals? Over the course of 5 years, we implemented 7 different projects under this umbrella CRIS that investigated various aspects of forest management on a wide variety of wildlife and invertebrates. Objective 1 – Impacts of forest management activities on wildlife. Sub-project A: We determined that pine straw raking impacts ground-dwelling arthropod communities, and that these effects change over time with repeated rakings.We have published one journal article on short-term effects of raking, and a second publication on long-term effects is currently in review; results were also shared via 1 newsletter article and a poster at a state-wide conference.As pine straw raking becomes an increasingly popular means of generating income from pine plantations in the Southeastern US, it is important to understand that repeatedly raking may have unintended consequences on arthropod communities that exacerbate over time, which may ultimately alter ecosystem functions that help maintain site productivity. Results should be useful to forest land owners andforest managers. Sub-project B: We found that prescribed burning has differential impacts on various species of bats, depending upon whether they forage above or below the forest canopy.The information learned was published in 1 M.S. thesis, 2 journal articles, 1 newsletter article, and shared through 2 conference presentations and 2 extension presentations. Although prescribed fire is recognized as an important tool for maintenance of natural successional dynamics in many forests of the Southeastern US, this is one of the first studies to demonstrate that fire frequency is an indirect determinant in structuring the communities of bats foraging in these forests. Results should be useful to land managers. Sub-project C:Wedetermined which vegetation community typeswild turkey hens select in south Florida, and which forest management activities are most beneficial. The information learned was published in 1 M.S. thesis, 1 newsletter article, and 1 conference presentation.Results suggest that a combination of prescribed burning and roller-chopping in relatively small patches is likely to benefit Osceola wild turkey hens by creating a mosaic with patches of dense vegetation within a more open matrix.Hens may initially avoid areas where understory vegetation is treated, but these areas will transition into preferred habitat2-3 years following disturbances. Results should be useful to land managers and hunters. Objective 2 – Impacts of human activities in non-forested habitats on animals that utilize neighboring forests. Sub-project D: We found that gopher tortoises are becoming less common on private lands in southern Mississippi, many individuals in this region have limited understanding of the habitat needs of the species, and residents are not enrollingin wildlife incentive programs which could reimburse funding spent to improve habitat for the species because of a percieved lack of flexibility in management options.The information learned was published in 1 M.S. thesis, 1 journal article, and 2 newsletter articles. Landowners who currently have tortoises tended to have several characteristics in common: larger acreage, longer ownership histories, longleaf pine forest habitat, and a desire to either provide a natural setting or provide recreation opportunities.Restoration may be most effecient if an education program that provides basicinformation about tortoisestargets individuals with the characteristics mentioned above.Results should be useful to land managers and extension educators. Sub-project E: We identified substances that have properties which attract attention from armadillos, worthy of further investigation as potential baits. The information learned was published in 2 journal articles and 1 extension publication, and shared at 1 state conference through a poster. We found that worms and crickets attracted the attention of armadillos more quickly than many other materials, armadillos visited the locations where worms and crickets were placed more often than locations with other materials, and armadillos spent significantly more time at the locations where worms and crickets were placed. However, because armadillos do not seem to recognize potential prey items until they are within very close proximity, trap placement is likely more important to capture success than selection of bait materials. Results should be useful to land owners experiencing damage caused by armadillos. Sub-project F: We identified wildflowers most and least susceptible to deer damage in the region. The information learned was published in 1 journal article, 1 popular magazine article, and 1 extension publication. Information on flowers most susceptible to deer feeding is useful to homeowners wanting to avoid planting species that could be damaged by deer, as well as to hunters interested in planting species that may attract deer.
