Many people wonder about the wildlife in various regions, often asking about diamondback rattlesnakes in Montana. Knowing snake species distribution is important for public awareness and appreciating natural ecosystems.
The Diamondback Question Answered
Western Diamondback Rattlesnakes (Crotalus atrox) and Eastern Diamondback Rattlesnakes (Crotalus adamanteus) are not found in Montana. These species inhabit warmer, more southerly climates. The Western Diamondback Rattlesnake ranges across the Southwestern United States, including Texas, New Mexico, Arizona, and parts of California, extending into northern Mexico. The Eastern Diamondback Rattlesnake is native to the Southeastern United States, from southeastern North Carolina through Florida and west along the Gulf Coast into Louisiana. Their habitats consist of dry, arid, or sandy environments, differing significantly from Montana’s diverse landscapes.
Rattlesnake Species Native to Montana
Montana is home to ten native snake species, but only one is venomous: the Prairie Rattlesnake (Crotalus viridis). This snake is widespread across Montana, found at elevations below 6,500 feet. Prairie Rattlesnakes favor open, arid country, but also inhabit ponderosa pine stands, mixed grass-coniferous forests, south-facing slopes, and rocky outcrops. They prey on rodents and small mammals, helping maintain ecosystem balance.
Identifying Montana’s Rattlesnakes
Distinguishing the Prairie Rattlesnake from non-venomous snakes in Montana is possible by observing key features. Prairie Rattlesnakes have a triangular head distinctly wider than their neck. They also possess elliptical pupils and a heat-sensing pit between each nostril and eye, characteristic of pit vipers. Their bodies are pale green to brown, marked with brown or black blotches along the back that often transition into rings near the tail. The most recognizable feature is the rattle at the end of their tail, though rattles can sometimes be lost or absent, and some non-venomous snakes, like gophersnakes or hog-nosed snakes, may mimic rattlesnakes by vibrating their tails or flattening their heads, but they lack these physical characteristics.
Coexisting with Montana’s Rattlesnakes
Encounters with rattlesnakes in Montana can be safely managed by following guidelines. Maintain a safe distance of at least 15 to 20 feet if a rattlesnake is encountered, allowing the snake ample space to move away. When hiking, stay on marked trails and watch where hands and feet are placed, especially around rocks, logs, and dense vegetation, to prevent accidental encounters. Wearing closed-toed shoes or boots and long pants provides protection against bites. Should a bite occur, remain calm, remove any constricting items like rings or watches, and seek immediate medical attention by calling 911. Avoid attempting to capture or kill the snake, cut the wound, apply ice, or use a tourniquet, as these actions can cause further harm.
