Colorado is home to a thriving moose population. These large mammals have established a strong presence in various regions across the state. Their majestic appearance and unique behaviors draw interest from residents and visitors alike.
Colorado’s Moose Population and Habitat
Colorado’s moose population, primarily consisting of the Shiras subspecies, has grown significantly, with current estimates suggesting over 3,000 individuals roaming the state’s mountain ranges. These animals are mainly found in the northern parts of Colorado, particularly in areas like North Park and the Grand Mesa. North Park, near Walden, is often referred to as the “Moose Viewing Capital of Colorado” due to its dense population.
Moose thrive in habitats that provide ample food and cover. They prefer forested areas, especially those near lakes, rivers, or wetlands. Riparian zones are rich in willows, a primary winter food source. Subalpine forests with abundant brush, twigs, and leaves are also suitable. Beyond North Park and Grand Mesa, moose have expanded their range into Middle Park, the Laramie River Valley, and parts of the San Juan Mountains in southwestern Colorado.
The Story of Colorado’s Moose
Moose were historically present in Colorado, with 1850s records indicating their presence, though they did not establish stable breeding populations. By the early 20th century, moose were largely absent from the state. The modern moose population in Colorado is largely a result of successful reintroduction efforts initiated by Colorado Parks and Wildlife (CPW).
The reintroduction program began in 1978 when 24 moose were transplanted from Utah and Wyoming to the North Park region near Walden. These animals adapted well to their new environment, with many cows even producing twins. Following this initial success, additional moose were introduced to other areas, including the Laramie River Valley in 1987 and the Upper Rio Grande River Valley in the San Juan Mountains during the early 1990s. These efforts have transformed Colorado’s moose population into one of the fastest-growing in the lower 48 states.
Responsible Viewing and Safety
When viewing moose in Colorado, prioritize safety and respect for wildlife. Moose are large, powerful animals that can be unpredictable, especially if they feel threatened or are protecting calves. Maintaining a safe distance is crucial; experts recommend staying at least 75 feet away.
Signs of a stressed or agitated moose include ears laid back, raised hair on the neck and back, or a lowered head. If a moose exhibits these behaviors, give them more space and avoid direct eye contact. If a moose approaches or charges, seeking immediate cover behind a large tree or solid object is advisable. Keep dogs on a leash, as moose perceive them as predators, which can trigger an aggressive response. Popular viewing areas, such as State Forest State Park in North Park and the Kawuneeche Valley in Rocky Mountain National Park, offer opportunities to observe moose from a safe distance.
