British Columbia is home to a diverse range of snake species, many of which are harmless but fascinating creatures worth understanding. Whether you’re a hiker, nature enthusiast, or just curious about the local wildlife, this listicle covers the most common and notable snakes in the region, providing detailed, accurate information to help you identify and appreciate these reptiles safely and responsibly.
Western Rattlesnake (Crotalus oreganus)
The Western Rattlesnake is the only venomous snake native to British Columbia and is primarily found in the southern parts of the province, especially in dry, rocky areas and grasslands. Recognizable by its distinctive rattle and dark, zigzag pattern along its back, it can grow up to 90 centimeters long. While its venom is potent, bites are rare and usually occur when the snake is accidentally provoked or threatened; humans are advised to keep a safe distance and respect its habitat.
Gopher Snake (Pituophis catenifer)
The Gopher Snake is a large, non-venomous constrictor that can reach lengths of up to 2 meters. It features a series of dark, saddle-shaped markings along its back on a light brown or yellowish background, mimicking the appearance of rattlesnakes as a defense mechanism. Common in open areas such as grasslands, prairies, and rocky slopes, Gopher Snakes are beneficial in controlling rodent populations and are generally harmless to humans.
Common Garter Snake (Thamnophis sirtalis)
The most widespread snake in British Columbia, the Common Garter Snake is small to medium-sized, usually around 45-60 centimeters. It has a distinctive pattern of yellow, green, or orange stripes running lengthwise on a brown or black background. These snakes are often found near water sources like ponds, streams, and marshes, where they hunt for amphibians, fish, and invertebrates. They pose no threat to humans and are considered beneficial for ecosystem health.
Sharp-Tailed Snake (Contia tenuis)
Less well-known but quite interesting, the Sharp-Tailed Snake is a small, secretive species typically measuring 25-35 centimeters. It has a slender body with a dark brown or black coloration and a distinctive pointed tail, which gives it its name. Found mostly in moist forests and under logs or leaf litter, this snake feeds on small invertebrates and is harmless to humans, making it a fascinating subject for ecologists and naturalists alike.
Rubber Boa (Charina bottae)
The Rubber Boa is notable for its smooth, shiny appearance and flexible body, often reaching lengths of 40-60 centimeters. Its coloration varies from tan to dark brown, and it has a blunt, rounded head with small eyes. Preferring forested and rocky areas, Rubber Boas are gentle, slow-moving snakes that feed on small mammals and are rarely encountered. They are harmless and play a vital role in controlling small pest populations.
Pacific Garter Snake (Thamnophis atratus)
Primarily found along the coast and in wetter habitats such as marshes and stream banks, the Pacific Garter Snake is a medium-sized species with a distinctive pattern of yellow or orange stripes on a dark background. It can grow up to 70 centimeters long and is active during the day. Its diet mainly consists of amphibians and fish, and it poses no danger to humans, although it can produce a mild, unpleasant musk when threatened.
Western Terrestrial Garter Snake (Thamnophis elegans)
This adaptable snake is common in a variety of habitats, including grasslands, forests, and suburban areas. It usually measures around 50-70 centimeters and displays a pattern of three yellow stripes running lengthwise on a dark brown or black background. It feeds on small amphibians, insects, and fish, and is harmless to humans. Its adaptability makes it one of the most frequently encountered snakes in BC.
Northern Pacific Rattlesnake (Crotalus oreganus oreganus)
A subspecies of the Western Rattlesnake, the Northern Pacific Rattlesnake inhabits the southern interior of British Columbia, especially in rocky, mountainous regions. It can reach lengths of up to 80 centimeters and exhibits a pattern of dark, irregular bands or blotches on a lighter background. Its venom is potent, but bites are rare due to its cautious nature. Respectful observation and keeping a safe distance are recommended when encountering this snake.
How to Choose
When selecting or encountering snakes in British Columbia, consider factors like habitat, size, and behavior. Non-venomous species such as garter snakes and gopher snakes are generally harmless and beneficial for ecosystems. Venomous snakes like rattlesnakes require caution—recognize their distinctive markings and rattle sounds. Always prioritize safety, respect their habitat, and avoid handling wild snakes unless trained and authorized. Your choice should depend on your comfort level, purpose (such as education or observation), and the importance of conservation.
