The Oscura Mountains Colorado Chipmunk (Neotamias quadrivittatus oscuraensis) is an approximately 20 cm (8 in; total length) long subspecies of Colorado Chipmunk (Neotamias quadrivittatus) that is only found in the Oscura Mountains of New Mexico. It is found at elevations of about 2,300-2,500 m (7,545-8,200 ft) on northwest-facing limestone cliffs in piñon (Pinus spp.)-juniper (Juniperus spp.)-oak (Quercus spp.) woodlands. Similar to the Organ Mountains Colorado Chipmunk (Neoamias quadrivittatus australis), the Oscura Mountains Colorado Chipmunk has an extended reproductive period and begins to breed in late winter/early spring. The Oscura Mountains Colorado Chipmunk will experience a high degree of climate exposure and has a moderately low adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Moderately Vulnerable under the Representative Concentration Pathway (RCP) 4.5 Scenario and Highly Vulnerable under the RCP 8.5 Scenario. The Oscura Mountains Colorado Chipmunk’s climate change vulnerability is impacted by factors related to distribution, movement, and abiotic niche, which influence its ability to shift in space and respond to climate change impacts.
