Pine voles (Microtus pinetorum) and meadow voles (Microtus pennsylvanicus) were studied in a commercial apple orchard in the Hudson Valley of New York during April and May 1981. Selected voles were given miniature radio transmitters and then tracked before and after herbicide application. A total of eight pine and meadow voles were tracked throughout the experimental period. Home range size decreased on the day following herbicide application but showed an increase from day 1 to day 5 & 7 after application. Movements away from the tree line into the aisles did not change significantly after herbicide use. We conclude that if herbicide is to have a significant impact on vole management in orchards, it must be used regularly in conjunction with other cultural practices.
