Venomous snakes in Oregon
The two venomous snake species in Oregon, the western (or prairie) rattlesnake and the Pacific rattlesnake have previously been considered to be one species. Therefore, several outdaten sources state that there is only one venomous snake species in Oregon. The two snake species can have a similar appearance but the Pacific rattlesnake is found in the eastern part of the state while the western (or prairie) rattlesnake is found in the eastern parts.
List of non-venomous snakes in Oregon
Of the fourteen non-venomous snake species in Oregon, four belong to the genus of garter snakes. Garter snakes can have a wide range of colors but usually have a dark body color with three lighter, often yellow, longitudinal stripes along their entire body. Other common harmless snakes in the state are the North American racer, the rubber boa and the ring-necked snake with its colorful belly. Oregon is also home to two native species of the kingsnake.
The Pacific gopher snake, including its subspecies the bullsnake, is a snake that has taken on the appearance and behavior of the venomous rattlesnake to deter predators. To learn more about each snake species, just click on the images or the links below.
