The Gray-banded Kingsnake (Lampropeltis alterna) is a medium-sized (1 m [3 ft] total length), slender, gray snake with black and orange banding. It is found from southeastern New Mexico to southwestern Texas and into central Mexico. It is active at night and found in dry, rocky, desert habitats of the Chihuahuan Desert. The Gray-banded Kingsnake 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 Gray-banded Kingsnake’s climate change vulnerability is impacted by factors related to distribution, demography, and abiotic niche, which influence its ability shift in space, persist in place, and respond to climate change impacts.

Assess the synergistic effects between climate change and other threats to SGCN and their habitats (e.g., Friggens et al. 2019, Parks et al. 2019). Incorporate appropriate climate adaptation strategies and frameworks into projects designed to address these synergistic effects. This may include enhancing connectivity (CEQ 2023), facilitating a species’ innate adaptive capacity (Thurman et al. 2022), enhancing genetic diversity (Powell 2023), considering local adaptation (Meek et al. 2023), or considering whether it is most appropriate to resist, accept, or direct ecosystem transformation (Lynch et al. 2021, Stevens et al. 2021). Projects should acknowledge ecosystem dynamism and incorporate indigenous knowledge (e.g., Roos et al. 2022, Eisenberg et al. 2024), nature-based solutions (Warnell et al. 2023), and experimentation (Guiterman et al. 2022) when appropriate.

Promote expanded use of appropriate, cost-effective grazing practices that ensure long-term ecological sustainability for SGCN and their habitats (especially riparian habitats). These include actions such as rest-rotation grazing management and conservation easements (Gripne 2005) that contribute to recovery of rangelands impacted by drought and allow restoration activities to be completed. May also include the use of virtual fencing to keep livestock in desired locations and out of sensitive areas (USFS 2024).

Agriculture and Aquaculture
Promote grazing systems that incorporate rested pastures and help improve overall range condition and enhance wildlife habitat health and function. In upland areas, these systems may include rest-rotation and/or deferred-rotation. In riparian areas, beneficial grazing practices may also include grazing in early spring and restricting summer grazing and redistribution practices such as herding and developing drinking water sources in upland areas. Especially during times of drought, rested pastures can provide forage reserves and relieve pressure on grazed pastures or allotments. Potential collaborators: BLM, NRCS, USFS, USFWS, SLO, private landowners, Tribal natural-resource managers.
Agriculture and Aquaculture
Promote use of ecoregion-appropriate agricultural practices that provide habitat or resources or protect habitat quality (e.g., reduce erosion) for SGCN, including planting rows of trees between crops (McCarthy 2024) and pollinator-friendly practices such as planting pollinator habitat along field margins and underutilized areas, revegetating retired farmland with wildflowers, including pollinator-friendly forbs in cover-crop seed mixes (O’Brien and Arathi 2021), waiting to mow along acequias or other areas until after pollinator-friendly plants finish flowering (e.g., Xerces Society 2018), and conserving semi-natural habitat near agricultural fields (Shi et al. 2024). Potential collaborators: NRCS, USFWS, NMDA, private landowners, Tribal natural-resource managers.

Where appropriate, incorporate native, pollinator-friendly plants (Glenny et al. 2022) or native plants adapted to projected future climatic conditions at the restoration site (e.g., Meek et al. 2023, Stanturf et al. 2024) into seed mixes and live plantings used in the restoration of lands affected by grazing, fire, resource extraction, energy development, or urban development. Consider reclamation site conditions, genetic diversity, and resilience to local threats when producing seedlings (Davis and Pinto 2021) and consider appropriate climate analogs when identifying appropriate seed sources (e.g., Richardson et al. 2024). When focused on benefiting pollinators, prioritize plants that are attractive to pollinators, especially SGCN; support pollinators throughout the growing season (Glenny et al. 2023); provide food for caterpillars of insect SGCN (e.g., Dumroese et al. 2016); and produce pollen with high nutritional diversity (Vaudo et al. 2024).
