The effects of intensive cattle grazing on oxeye daisy (Chrysanthemum leucanthemum) were examined in a two year study northeast of Bozeman, Montana. The first year of grazing was on six, 12-ha paddocks. During the second year of grazing there were only three 24-ha paddocks. Paired 10-m transects were permanently located in the high oxeye daisy density with half of these transects excluded from grazing. Oxeye daisy stems were counted and assigned to seedling, rosette or mature stem categories. Timothy, smooth brome and dandelion were counted with frequency taken on Kentucky bluegrass and orachardgrass. Mature oxeye daisy stems and grass plants were permanently marked and visited after 2, 4, and 6 days of grazing to determine if they were grazed, trampled, or removed and height of each was remeasured. Soil cores on each site were collected before grazing began and after the conclusion of the trial to determine the seedbank of oxeye daisy.
