Abstract:White pine bark infected with the white pine blister rust is often fed upon by rodents of various kinds. Most of the feeding takes place during late winter or early spring, a time of year when food materials are naturally scarce. At some pine infection areas removal of the infected bark is so extensive as to result in a considerable reduction in volume of aeciospores, the spore stage which infects currants and gooseberries--the alternate host plants of the rust.
