(1) The responses of small-mammal populations to a forest application of RoundupR herbicide* have been investigated at the University of British Columbia Research Forest, Maple Ridge, B.C., Canada. (2) These populations included the deer mouse, Oregon vole, Townsend chipmunk, and shrews. (3) Treatment of a 20-yr-old Douglas fir plantation did not have any negative effects on the distribution and abundance of small-mammal populations during the first year after this habitat alteration. (4) Movements of deer mice were monitored by drift lines. There was not an influx of new animals from the surrounding regions onto the treated area nor was there a significant movement of marked animals away from the sprayed area. (5) Future changes in composition of the small-mammal community may occur in association with successional stages advancing from the herbicide-induced habitat alteration.
