The Gila Monster (Heloderma suspectum) is a large (up to 0.6 m [2 ft] total length), heavy-bodied lizard with pinkish-orangish and black, beaded skin and a venomous bite. It is found from southern California and Nevada to southwestern New Mexico and northwestern Mexico. In southwestern New Mexico, it can be found in desert, mesquite-grassland, pine (Pinus spp.)-oak (Quercus spp.) forest, tropical-deciduous forest, and thorn-forest habitats. The availability of refuge shelters, including rock cavities and crevices, is crucial for this species. The Gila Monster 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 RCP 4.5 and RCP 8.5 Scenarios. The Gila Monster’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. It is impacted by barriers, land-use changes, and other anthropogenic factors that could increase the effects of climate change. It also has documented or modeled responses to climate change that impact its vulnerability score.
