Responses of small mammal populations to a forest herbicide application in a 20-year-old conifer plantation.
Populations of deer mouse, Oregon vole, Townsend chipmunk and shrew were examined before and after the application of glyphosate in a 20-yr-old plantation of Douglas fir. The herbicide did not appear to affect either the distribution or abundance of small mammals during the 1st yr after treatment. A special study of the deer mice showed little movement of animals into or away from the treated area. Future changes in composition of the small-mammal community may occur in association with successional stages advancing from the herbicide-induced habitat alteration.
