Current Research

My research examines the impacts of forest management practices on the distribution, abundance, and demography of vertebrate populations, and quantification of the habitat requirements of wildlife communities and species of special concern on the Allegheny Plateau.

  • Assessment of the impact of timber management on the abundance and demography of cerulean warblers.
  • Understanding the frequency and costs/benefits of use of clearcuts by forest interior birds in the post-fledging period.
  • Assessment of impacts of an herbicide tank mix on avian, mammal, and herp communities in Allegheny hardwood forests.
  • Assessment of the effects of prescribed fire on wildlife taxa of concern.

 

Research Interests

  • Develop silvicultural guidelines for maintaining or enhancing habitat quality for cerulean warblers and other forest bird species of high conservation concern.
  • Develop a wildlife community component to the SILVAH decision support system to predict responses of suites of vertebrate species to silvicultural treatments and to better integrate wildlife habitat as a management goal.
  • Because not all species are of equal conservation concern, standard metrics such as species counts and diversity indices provide only a partial picture of the impacts of management on natural communities. With partners at the U.S. Aviary, I will develop and implement a conservation value metric as a tool to evaluate the contribution of communities based on existing conservation priority, such as the Partners in Flight prioritization scores or heritage rankings
  • Determine the local and cumulative effects of oil and gas development on forest wildlife.

Why This Research is Important

Managers of public lands are mandated to manage for multiple objectives, including maintaining biodiversity. Populations of many forest birds have declined in recent decades, raising concerns about their viability in working forest landscapes. Scientifically sound information on the habitat requirements of these species and how they respond to management practices is essential for managers to maintain these species effectively.

National Research Highlights

Conventional Oil and Gas Development Alters Songbird Communities (2014)
A Forest Service scientist and partners found that as the density of oil and gas wells increased, the amount of core forest habitat decreased sharply. Forest interior species were less abundant at well sites than reference sites and showed a declining trend with increasing well density. The scientists examined the effects of conventional oil and gas development on forest habitat, the abundance of songbird species and guilds, species diversity, and community similarity within and between mixed hardwood and oak forest types at both individual wells and at the 25-hectare (61 acres) scale in forested blocks with no wells, low, or high well density.


Long-Term Differences in Forests With Different Deer Densities (2011)
Thirty years after a study on the effects of deer on forest ecosystems established new forest stands at deer densities ranging from 10 to 64 deer per square mile, Forest Service scientists found that tree species diversity, canopy foliage density, insect density and bird density, all decreased significantly as the deer density at stand initiation increased. If deer densities were high initially, the effects carried over, even if densities were lower later.


Scientists Study Long-term Response of Ground Beetle Communities to an Operational Herbicide Application (2013)
Ground beetles comprise a large and diverse group of mostly predatory beetles that have long been recognized as a useful barometer of ecosystem health. As part of a long-term, large-scale study of the impacts of an operational herbicide-shelterwood treatment, Forest Service scientists found no treatment response by ground beetles as measured by abundance or diversity. However, their numbers and diversity were strongly correlated with natural outbreaks of forest lepidopterans, an order of insects that include moths and butterflies.


Timber Harvests Create Beneficial Habitat for Forest Birds (2013)
Many songbird species that require intact, mature forest for breeding have been found by Forest Service researchers to move into young thickets created by timber harvest after breeding. Further, those birds that shift habitats tend to be in better physiological condition than those that do not, indicating such habitats confer fitness benefits. These research results indicate that early-successional habitats created by timber harvests provide an important resource for many mature-forest birds.


Using New Technology To Track a Rare Songbird During Migration (2014)
The cerulean warbler is a tiny forest bird in big trouble. To better understand where these birds go when they migrate out of their Appalachian breeding grounds, Forest Service scientists and university partners have begun using light-detecting geolocators: tiny backpacks that record the birds' locations. When recovered next spring, these geolocators will reveal where the birds traveled, which will help inform where conservation efforts should be focused.
