During routine necropsies of snowshoe hares, Lepus americanus, captured in north-central Alberta, lesions in the glandular portion of the stomach were observed in 34.5% (444/1286) of trapped hares as opposed to 10% (12/120) of snared hares and 0% (0/10) of shot hares. Among the trapped hares, gastric lesions were almost twice as common in juveniles as in adults, 43.7% (293/670) and 24.5% (151/616) respectively. There was no significant differences in the frequency of lesions between sexes. A gross and a microscopic description of the lesions are presented.
