Ecology and Conservation of Neotropical Migrants in the Southern Appalachians

This study seeks to develop an ecosystem level approach to understanding the conservation needs of Neotropical migratory birds in the southern Appalachians. Great Smoky Mountains National Park (GRSM) is being established as a control site for...

Results summary:

  • For all years combined we established and censused 4,159 independent plots and conducted 3,414 repeat counts. In total, we recorded 74,797 individuals of 115 species. The increase in the total number of species observed over time is due to increased census coverage of the park, particularly in unique areas such as Cades Cove and The Purchase.
  • ,
  • We did not detect any major differences in bird community composition or abundance between years. The relative abundance of some species did change from year to year, but these changes are consistent with differences in the sampling locations for each year.
  • ,
  • In 1998 we combined census data with variables from the GRSM Geographic Information System (GIS) database to develop a logistic regression model for Wood Thrush. The model predicts the probability of detecting a Wood Thrush as a function of several habitat and topographic variables.

The effects of landscape pattern, core areas, and forest managment practices on avian communities in the Southern Appalachians

This study expands an avian community study in Great Smoky Mountains National Park (GRSM) to include U.S. Forest Service lands adjacent to the Park. GRSM will be used as a control site to examine breeding populations of forest...

Effects of Atmospheric Pollution on High Elevation Fauna in Great Smoky Mountains National Park

The goal of this research is to examine the effects of atmospheric pollution on two groups of high elevation terrestrial animals. Air pollution such as acid precipitation and mercury toxicity remains high in eastern forests, and is considered a...
