Methodology Colorado Parks and Wildlife (CPW), utilizes an annual Big Game Harvest Survey of Colorado hunting license holders as part of managing the deer, elk and pronghorn herds and allocating licenses.

5 CPW. contracts with a third party vendor who conducts the annual Harvest survey using an email/online based survey in conjunction with live operator telephone based survey. The annual Big Game Harvest Survey is designed to collect general Harvest and participation data for all seasons and manners of take at a Data Analysis Unit (DAU) level. Each DAU represents a geographic area that a herd will utilize throughout the year and consists of one or more Game Management Unit (GMU). GMUs are used to manage hunter distribution through established hunts and licensing levels. This annual survey is designed to support DAU population modeling. By collecting and analyzing survey responses at the larger herd management-based scale, errors in data reporting and standard error estimates are reduced. CPW sold approximately 347,000 deer, elk and pronghorn licenses for nearly 2,900 different hunts.

6 Hunts held between August 15, 2020 and January 31, 2021 that were available to the general public through the limited license draws, Landowner Preference Program (LPP) vouchers, Over-The-Counter, and Leftover sales were included in the annual Big Game Harvest Survey. To ensure all hunts were included in the DAU estimates, the Big Game Harvest Survey used stratified random sampling of licenses based on hunt code, residency and/or hunter age group. This voluntary sample based survey allows CPW to estimate Harvest more cost effectively and without the penalties for noncompliance necessary with a mandatory survey. In total, 324,440 licenses were sold for hunts included in the 2020. Harvest survey resulting in 185,080 deer, elk and pronghorn licenses being sampled overall. In addition, 207,600 licenses were sold for the 1,070 elk hunts include in the annual Harvest survey.

7 51. of those licenses had invalid contact information at the time of sampling and were not included in the sample. The stratified random sampling resulted in 123,091 elk licenses being selected for the annual Harvest survey. At the end of data collection, 51,958 elk surveys had been completed resulting in a 42. percent overall response rate. The Harvest figures are estimates of Harvest and participation extrapolated by comparing survey responses to licenses sold. The DAU estimates are followed by the standard error (SE) of the estimate which is a measure of the precision of the estimate. The 95% Lower Control Limit (LCL) and 95% Upper Control Limit (UCL) columns provide the upper and lower values for the 95% confidence limits around the estimate. For example, we estimated total Harvest of elk for DAU E-6 at 7,013 with a SE of 185. The 95% confidence interval range estimates that between 6,660 and 7,384 elk were harvested in E-6.
