West of I-25 SE Deer Data Analysis Units Herd Management Plan

Colorado Parks and Wildlife (CPW) manages five mule deer herds west of I-25 in the Southeast Region (see descriptions and map below). CPW is currently revising the herd management plans (HMPs) for these five herds. The HMPs will identify desired population and buck-to-doe ratio objectives that will guide mule deer management for a 10-year time frame. Public input is an important part of the planning process, and we are interested in your input on mule deer management in these herds. The information you provide will help guide the management of the five SE Region West of I-25 mule deer herds from 2026-2036.
