Moose in Colorado

Moose Background

Moose, (Alces alces), are the largest members of the deer family and are found in the northern regions of North America, Europe and Asia. Moose prefer habitat near lakes, rivers or wetlands, where they feed on young plants including shrubs, aquatic plants, grasses, mosses, willow, and aspen.

In 2013, moose inhabited northern forests in 15 states. Twelve states – including Colorado - offered moose hunting. The moose in Colorado belong to the Shiras subspecies, which are smaller than the subspecies found in Alaska and Canada. Colorado’s adult moose can run 35 miles per hour, weigh up to 1,000 pounds and stand six feet tall at the shoulder.

Herd Management Plans

Moose Management

The purpose of a Herd Management plan (HMP) is to integrate the plans and intentions of Colorado Parks and Wildlife with the concerns and ideas of land management agencies and interested public to determine how a big game herd in a Data Analysis Unit (DAU) should be managed.

Big game populations are managed to achieve population and sex ratio objectives established for Data Analysis Units. A DAU is the geographic area that represents the year-around range of a big game herd and includes all of the seasonal ranges of a specific herd. Each DAU usually is composed of several Game Management Units (GMUs), but in some cases only one GMU makes up a DAU.

    Draft Herd Management Plans

    There are currently no draft plans open for public comment. When comment periods are available, they are open for 30 days.

    About the Draft Plan Process

    Traditionally, Colorado Parks and Wildlife staff have presented one herd management plan at a time for approval to the Parks and Wildlife Commission. In order to address the large numbers of HMPS that need to be updated, staff have taken a new approach to develop a regional roll-up of all HMPs in a CPW region for a single big game species to update or establish new population and sex ration objectives. The regional plans also describe the significant management issue for herds within each Region, what public input was used to develop proposed objectives, and the individual HMPs for each herd.

    About Preparing an HMP

    In preparing an HMP, agency personnel attempt to balance the biological capabilities of the herd and its habitat with the public's demand for wildlife recreational opportunities.

    The primary decisions needed for each HMP plan are how many animals should exist in the DAU and what is the desired sex ratio for the population of big game animals (e.g., the number of males per 100 females). 

    The selection of population​ and sex ratio objectives (which are set for a 10-year period of time) drive important decisions in the big game season setting process, namely: 

    • How many animals must be harvested to maintain or move toward the objectives 
    • What types of hunting seasons are required to achieve the harvest objective

    History of Moose in Colorado

    Historical records dating back to the 1850s indicate that moose wandered into northern Colorado from Wyoming, but were transient and never established a stable breeding population. Most of the historic sightings involved hunters seeing and/or harvesting a single bull moose.

    Moose Reintroduction

    In the 1950s, Colorado wildlife officials considered bringing moose to the state. There were concerns, voiced at public meetings on a series of proposals, that moose would compete with cattle and sheep on grazing land, and potentially damage local ecosystems and other wildlife species. State wildlife managers advocated moose reintroduction because of the abundant habitat available and lack of natural predators.

    During the 1960s and the early 1970s, the Colorado Division of Wildlife (now Colorado Parks and Wildlife) worked with the U.S. Forest Service, the Bureau of Land Management, the National Park Service, the general public and local ranchers on selecting the North Park area in the Routt National Forest near Walden as the site for the first moose reintroduction.

    In 1978, state wildlife experts transplanted 24 male and female moose from Wyoming and Utah to create a breeding population in North Park and provide hunting opportunities. Additional moose from Wyoming, Utah and Colorado’s own growing population were introduced to other areas of western Colorado over the years. The project succeeded in creating new hunting opportunities and a popular wildlife viewing option. The state legislature, in 1995, declared Walden the “Moose Viewing Capital of Colorado.”

    By 2012, the reintroduction program had established a breeding population of about 2,300 moose in Colorado.  Moose hunting is available in 39 game management units (GMUs). There were 16,500 applicants for 219 moose hunting licenses and 185 moose were harvested in 2012. While the moose population in other states has declined, Colorado’s moose population continues to grow.
