Sonoran Mountain Kingsnake (Lampropeltis pyromelana)

F O C U S  O N  C O N S E R V A T I O N

The Sonoran Mountain Kingsnake (Lampropeltis pyromelana) inhabits 
rocky montane habitats from 850 m to almost 2800 m (2800–9100 
ft) in the western United States and adjacent regions in Mexico. In 
Nevada, the documented distribution of the species is limited to 
isolated populations in mountain ranges along the state’s eastern 
border. However, due to the remoteness of this area and the secretive 
habits and low densities of the species, the distribution of the Sonoran 
Mountain Kingsnake is unknown. Data on distribution, population 
trends, and genetics of Nevada populations are needed to properly 
manage the species. 

Sonoran Mountain Kingsnakes are protected in Nevada and also are 
listed as a “Species of Conservation Priority” in the state’s Wildlife Action 
Plan (www.ndow.org). The Nevada Department of Wildlife and Great 
Basin National Park have formed a partnership to conduct surveys to 
determine the species’ distribution, abundance, and habitat preferences. 
Genetic samples are collected for comparisons with other populations 
to determine what relationships exist between Nevada kingsnakes and 
the closest metapopulations. The results of these surveys and genetic 
analyses will aid greatly in the management of this protected reptile. 
In addition to the local conservation efforts, the Southwest Chapter of 
Partners in Amphibian and Reptile Conservation (PARC) is addressing 
the conservation of the Sonoran Mountain Kingsnake on a regional 
— or range-wide — level. Partners from a wide range of organizations 
representing management, education, research, non-governmental and 
not-for-profit organizations, Native American tribes, the pet trade, 
zoos, and hobbyists are working together to identify and implement 
the conservation needs of this species throughout its range.
