In 1910, Colorado had less than 1,000 elk; today, the state population is estimated to be the largest in the country, with more than 290,000 elk. Over the last two decades, however, Colorado Parks and Wildlife has become increasingly concerned about declining calf recruitment (the number of calves making it to adulthood). In 2017, researchers began a 2-year pilot study to investigate factors influencing elk recruitment in two study areas in the state. The initial pilot project was expanded into a 3rd study area in 2019 and the research continues to better understand elk population dynamics in Colorado and determine how predators, habitat, and weather conditions are impacting elk recruitment in Colorado.
