Combining the June and fall datasets, we will compare adult female body condition and calf body condition and early growth in the two herds. The comparison of the fall dataset with data collected at calving will provide us with direct information on the body condition and indirect information on the quality of the summer range use by female-calf pairs of each herd. Differences in body condition of female-calf pairs may be useful indicators of demographic changes. Our results already suggest large differences in body condition between herds, possibly indicating different demographic trends.
