The Mottled Rock Rattlensake (Crotalus lepidus lepidus) is a medium-sized (up to 61 cm [24 in]) species in the pit viper subfamily (Crotalinae) that is found in rocky, mountainous regions of the southwestern regions of the US, including Doña Ana, Eddy, Otero, and Sierra Counties in New Mexico. This snake is extremely venomous; it is armed with a hemotoxic venom that causes tissue damage in its prey. It eats small mammals, lizards, frogs, birds, and sometimes other snakes. The Mottled Rock Rattlesnake will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Mottled Rock Rattlesnake’s climate change vulnerability is impacted by factors related to distribution, demography, and abiotic niche, which influence its ability to shift in space, persist in place, and respond to climate change impacts.
