Progress 08/01/05 to 06/30/10
Outputs
OUTPUTS: A long-term study began in June 2005 and extended to June 2010, which continues the research at Penn State (since 1982) on the effects on wildlife of land-uses on conservation and management on public lands (e.g, national parks), agricultural, and forested stands. I have documented that larger or linear habitats are more beneficial to various wildlife rather than smaller, block-like habitats. The status of different wildlife species, e.g., goldeni-winged warblers or rose-breasted grosbeaks, on Pennsylvania's public land, agricultural, and forestland is needed for an understanding of the long-term status of wildlife species in response to these changing lands. This information helps me and others in future research, teaching, and outreach. PARTICIPANTS: R. H. Yahner TARGET AUDIENCES: Wildlife agencies, public utilities, forest industry, and private forest landowners PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
I have conducted research a 5- year study (2005-2010) on long-term trends of various wildlife species on public lands (e.g, national parks), agricultural, and even-aged management of forested stands, at Penn State, which began in 1982. Current research is a continuation of these studies and provides valuable information to wildlife agencies, the forest industry, utilities, and private forest landowners on the effects of land-use practices on wildlife ranging from forest to national parklands. Benefits need to be considered simultaneously, including economic, aesthetic, and wildlife benefits, in habitat management goals for wildlife.

OUTPUTS: This long-term study in June 2005, which continues research at Penn State (since 1982) on the effects of land-uses on conservation and management of wildlife on public land (e.g, national parks), agricultural, and forested stands. I have documented that larger or linear rather than smaller tracts of undisturbed habitat or early successional habitat are necessary for the long-term conservation of wildlife. The status of wildlife species, e.g., rose-breasted grosbeaks, on Pennsylvania's public land, agricultural, and forestland is needed for an understanding of the long-term status of wildlife species in response to these changing lands. This information is important to research, teaching, and outreach. PARTICIPANTS: Nothing significant to report during this reporting period. TARGET AUDIENCES: Wildlife Agencies, Public Utilities, Forest Industry, and private forest landowners PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
I have been conducting research on the long-term trends in wildlife species using even-aged management of forested stands, public land (e.g, state game lands,national parks), and agricultural, at Penn State since 1982. My current research is a continuation of these studies and provides valuable information to wildlife agencies, forest industry, utility foresters, and private forest landowners on the effects of land-use practices, ranging from forest to national parklands, on wildlife. Various benefits need to be considered simultaneously, including economic, aesthetic, and wildlife benefits, in habitat management goals designed for wildlife.

Progress 01/01/07 to 12/31/07
Outputs
OUTPUTS: My study began in 2005 and is intended as a continuation of research on the long-term effects of land-uses, including even-aged management of forested stands, on wildlife. Large tracts of undisturbed habitat or tracts of early successional habitat may be required for the conservation of certain wildlife species. With the recent publication of the report on the status of Pennsylvania's forests, information is needed on the long-term status of species in response to the changing forests of the Commonwealth, which is valuable to research and outreach.
PARTICIPANTS: R. H. Yahner, Project Leader
TARGET AUDIENCES: Wildlife agencies, forest industry, and private forest landowners
Impacts
I have studied long-term trends in wildlife communities and populations using public lands in Pennsylvania (state game lands and national parks) since 1982. This research provides valuable information to wildlife agencies, forest industry, and private forest landowners on the effects of land-use practices, ranging from silvicultural practices to management goals mandated by national parks or desired by the public, on wildlife. Economic, aesthetic, and wildlife benefits simultaneously must be considered in habitat management goals.

Progress 01/01/06 to 12/31/06
Outputs
I initiated a project in 2005 that focuses on the impacts of silvicultural and other land-uses on wildlife, especially songbird communities, individual species (e.g., chestnut-sided warblers), and raccoons. This project has been centered in central and western sectors of the state and on both public an dprivate lands. Data obtained from the study will provide important information fro mresearch and outreach perspectives, in particular.
Impacts
My research provides data that have important scientific, conservation, and management impacts for use by various federal, state, and private stakeholders, such as the Bureau of Forestry, Pennsylvania Game Commission, public utility companies, National Park Service, and private forest landowners. These studies provide valuable information on the long-term effects of land-use practices on wildlife on public and private in Pennsylvania and throughout the eastern deciduous forest. An understanding of wildlife to changing landscapes and land management is relevant to society and the scientific community. Both short- and long-term impacts need to be understood to ensure the conservation and sustainability of wildlife abundance and diversity in landscapes that are modified or changing due to human intervention or landscape patterns.
