Squirrel Population by State 2025

Squirrels, with their bushy tails and nimble movements, are a common sight across the United States, playing important roles in ecosystems as seed dispersers and prey for predators. While there are over 65 species of squirrels in the country, the table bellow focuses on the most prevalent species, including tree squirrels, ground squirrels, chipmunks, and flying squirrels. These species collectively comprise the vast majority of the national squirrel population, although their exact numbers remain uncounted due to the challenges of assessing such widespread and often elusive creatures.

The distribution of squirrel species varies across different states, influenced by factors such as habitat availability, climate, and historical introductions. For example, states like Oregon and Washington boast diverse populations that include the American Red Squirrel, Douglas Squirrel, and various species of flying squirrels, reflecting the rich coniferous forests and abundant tree cover in the Pacific Northwest. In contrast, states like Arizona and New Mexico are home to unique species such as the Abert’s Squirrel and the Harris’s Antelope Squirrel, adapted to arid desert environments where vegetation is sparse.

Despite their adaptability and widespread presence, squirrels face threats from habitat loss, urbanization, and predation by domestic pets. Conservation efforts aimed at preserving natural habitats and minimizing human-wildlife conflicts are crucial for ensuring the continued well-being of squirrel populations across the United States. As stewards of the environment, it is important for communities to appreciate the ecological importance of squirrels and work towards coexistence with these charismatic and ecologically valuable creatures.
