Black bears are an iconic part of Colorado’s diverse wildlife. These adaptable animals play a significant role in the natural ecosystem, and understanding their population dynamics is important for both wildlife conservation and human-wildlife coexistence. The question of how many black bears inhabit Colorado is a common one.
Colorado’s Black Bear Population Estimate
Colorado Parks and Wildlife (CPW) estimates the black bear population in the state to be between 17,000 and 20,000 animals. This estimate indicates a stable and potentially growing population. While called “black bear,” many individuals in Colorado exhibit fur colors from brown, cinnamon, and honey to blond, with only a smaller percentage being truly black.
These figures represent an estimate rather than an exact count, as obtaining a precise number for a wild and elusive species across a large geographic area is challenging. The population’s health and stability are considered good, though factors like habitat availability and human-bear conflicts can influence local densities.
Tracking and Managing Bear Populations
Wildlife agencies, including Colorado Parks and Wildlife, employ various scientific methods to estimate and manage black bear populations. These efforts support informed conservation strategies and mitigate human-bear interactions. One common method involves non-invasive genetic surveys, where hair samples are collected from “hair snares.” These snares, often barbed wire corrals with bait, allow bears to rub against them, leaving hair for DNA analysis without direct capture.
DNA analysis from these hair samples helps identify individual bears, providing data for population density and size estimates. Researchers also use GPS satellite collars to track bear movements, feeding patterns, and monitor survival and reproduction rates, sometimes visiting winter dens of collared females. This data helps wildlife managers understand how urban environments influence bear behavior and trends, aiding in strategies to reduce human-bear conflicts. Such studies are important for population management and implementing measures like bear-resistant trash cans, which effectively reduce conflicts.
Black Bear Habitats in Colorado
Black bears are found across nearly all forested areas of Colorado, demonstrating their adaptability to various environments. Their typical habitats include forested mountains, foothills, and riparian areas along rivers, even in otherwise treeless plains. They often seek out areas rich in natural food sources, such as Gambel’s oak and aspen stands, along with chokecherry and serviceberry bushes.
The majority of Colorado’s black bears reside in the western half of the state, where these suitable habitats are more prevalent. Black bears move seasonally, often shifting to lower elevations in the fall to access fruits and nuts. The availability and quality of these habitats directly influence bear populations, as they provide the necessary food, water, and cover for survival and reproduction.
