The sun is coming out, the hiking trails are heating up, and more East Bay residents are heading out to get some vitamin D. But they’re not the only ones looking to soak up the sun. With warmer temperatures on their way, the local rattlesnake population is also taking to the trails.
On April 30, the East Bay Regional Park district issued a rattlesnake advisory, advising park visitors how to stay safe this summer as rattlesnakes emerge from hibernation.
In the wintertime, when temperatures consistently drop below 60 degrees, the cold-blooded rattlesnakes go into a “hibernation-like state” known as brumation which they can stay in for several months, according to the California Department of Fish and Wildlife. Once the weather warms up, they become more active, especially at dawn and dusk when they are at lower risk of overheating. The reptiles use the sun and changing temperatures to regulate their body functions.
Rattlesnakes are a vital part of our California ecosystem. They live in a diverse range of habitats, including rural, urban, forested, and desert environments. They also help manage rodent and other reptile populations.
While usually not an aggressive animal—rattlesnakes tend to avoid people, and bites are extremely rare—they can be dangerous if they feel threatened. East Bay Regional Park officials warn parkgoers to take necessary precautions to keep themselves and the rattlesnakes safe.
When heading out onto a trail, it’s important to keep your eyes on the path and scan for any rattlesnakes that may be lying out. Similarly, if you’re resting on a log or rock, make sure to check the area before you sit down. Remember to always stay on the trail and avoid walking in tall grass. You can also keep an ear out for the rattlesnake’s telltale buzz of its rattle, which acts as a warning from the animal.
If you do happen to see a rattlesnake, leave it be. Move slowly and carefully around or away from the animal, giving it lots of space.
In the unlikely event that you are bitten by a rattlesnake, remain calm and have someone call 911 immediately. The park district also advises that you keep the affected limb below your heart. You should not use a tourniquet or try to remove the venom yourself. If you are alone, call 911 or walk calmly to the nearest phone. You should avoid running, but seeking medical care as soon as you are able is vital.
The parks district also has additional information on wildlife encounters as well as resources to properly identify rattlesnakes.
