What Kind of Rattlesnakes Live in Northern California?

Northern California is known to harbor two distinct species of rattlesnakes: the Northern Pacific Rattlesnake (Crotalus oreganus oreganus) and the Great Basin Rattlesnake (Crotalus oreganus lutosus). These snakes add a unique element to the region's ecosystem.

Understanding Northern Pacific Rattlesnake (Crotalus oreganus oreganus)

The Northern Pacific Rattlesnake is one of the more common venomous snakes found in Northern California. It is characterized by its distinctive rattle at the end of its tail and its relatively moderate length. Typically, adults reach an average length of 36 inches, though some may grow up to 48 inches in exceptional cases. Found in various habitats, including open hillsides, meadows, and woodlands, these rattlesnakes are prevalent in areas east of the Sierra Nevada and in the Modoc Plateau located in the far northern part of the state.

Exploring the Great Basin Rattlesnake (Crotalus oreganus lutosus)

Another rattlesnake species commonly found in Northern California is the Great Basin Rattlesnake, known scientifically as Crotalus oreganus lutosus. While still venomous, the Great Basin Rattlesnake is generally slimmer and longer than the Northern Pacific Rattlesnake, with adults typically measuring between 3 and 4 feet in length. This species is more specifically found in the Great Basin region, which extends into northeastern California, and typically resides in habitats such as rocky deserts and sagebrush-covered areas. Their slightly larger size and reputation for being more cautious and harder to approach make them somewhat distinguishable from the Northern Pacific Rattlesnake.

Snakes in Northern California: A Mix of Venomous and Non-Venomous Species

Besides the rattlesnakes, Northern California hosts a diverse array of snake species, both venomous and non-venomous. While the western rattlesnake, a type of Northern Pacific Rattlesnake, is included in the list of snakes common to the region, it is worth noting that it is generally more aggressive than its eastern counterparts. On the other hand, the eastern rattlesnake, found in the eastern part of California, is known for its timidity and shyness.
