Few long term studies have been conducted to analyze the population dynamics of pine and meadow voles in orchard environments. Such studies are needed to provide basic biological information for use in orchard management and vole control programs. To satisfy these needs, a three year study was begun in December, 1979, to monitor vole populations in a maintained and an abandoned apple orchard in Southwest Virginia. Two objectives of this study were (1) to follow population dynamics of pine and meadow voles in two orchard types and (2) to provide data for the development and validation of computer modeling efforts currently underway at Virginia Tech (Jordan and Tipton 1982). Lindquist et a1. (1981) gave preliminary results from the field study after one year of trapping. This paper presents data from the second year of trapping (December 1980, to December, 1981) and compares the pine vole populations in the two orchards during the two years.
