There are places in Eagle County where there seem to be plenty of elk. But the long-term survival of those herds is in question.
Colorado Parks and Wildlife is currently working on a 10-year herd management plan, and Eagle County contains portions of four “Data Analysis Units” in the study. The Eagle County Board of Commissioners heard a report Tuesday about the study so far from a trio of CPW officials.
Wildlife biologist Julie Mao told the commissioners that there’s only so much officials can do to try to manage herds. The most significant of those tools is issuing hunting licenses in order to manage herd populations and the ratio of bulls to cows. But there’s no real way to manage cow/calf ratios in those herds. Those ratios are a long-term indicator of the health of a particular herd.
The cow/calf ratios — the number of healthy calves in a herd — have declined significantly since the 1980s.
Mao said the ratio 40 years ago was roughly 60 calves for every 100 cows. That ratio today is in the mid- to upper 30s. That means herds today are less resilient.
