Scientific Name Trimorphodon vilkinsonii
Category D
Taxon Reptiles
Climate Change Vulnerability Score Less Vulnerable
View on BISON-M

The Texas Lyresnake (Trimorphodon vilkinsonii) is a medium (~ 1 m [3 ft]) snake that is found in rocky, arid regions of New Mexico, Texas, and northern Mexico. It is mildly venomous and not considered dangerous to humans. Its diet consists mainly of lizards, birds, and small mammals. The Texas Lyresnake 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 Texas Lyresnake’s climate change vulnerability is impacted by abiotic factors, which influence its ability to respond to climate change impacts.

Threats and Conservation Actions

Result for: All
Transportation and Service Corridors
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. Potential collaborators: BLM, NPS, USFS, USFWS, USGS, universities, Tribal natural-resource managers.

Transportation and Service Corridors
Collaborate with interested and willing land managers and private landowners to designate protected areas or implement conservation easements for lands that encompass important SGCN habitats. Potential collaborators: BLM, NPS, NRCS, USFS, USFWS, SLO, non-profit organizations, private landowners.

Transportation and Service Corridors
Determine life history needs, ecology, distribution, movements, status, and trends of and threats to SGCN (especially invertebrates that are not currently monitored, riparian-obligate species, herpetofauna [Pierce et al. 2016, Olson and Pilliod 2022], and rare native fishes) and their habitats. Consider full annual cycles for migratory species when appropriate and logistically feasible (KFF 2021) and interactions with lower trophic levels that may drive SGCN status (e.g., EPA 2023). Use this information to develop and implement effective monitoring protocols and conservation actions, including actions to mitigate identified threats. Potential collaborators: BLM, BOR, NPS, USFS, USFWS, SLO, universities, non-profit organizations, private industry, species working groups, Tribal natural-resource managers.

Transportation and Service Corridors
Determine where roads, vehicle traffic, and utility lines are inhibiting or preventing movement of SGCN, including during migration. Identify and conserve natural habitat corridors, especially those at risk from future fragmentation by roads or utility lines. This may include reconnecting stream and wetland habitats that have been fragmented by roads, culverts, and other man-made structures that isolate and preclude movement of aquatic and semi-aquatic SGCN. Does not include structures that serve a beneficial role for wildlife (e.g., native fish barriers). Re-establish SGCN in areas where extirpated and appropriate. Potential collaborators: BLM, NPS, USFS, NMDOT, universities, non-profit organizations, private landowners, utility companies.

Transportation and Service Corridors
Evaluate the effectiveness of public education and outreach efforts regarding threats to SGCN and their habitats and the ways that the public can assist in threat mitigation (KFF 2021). Modify outreach activities as needed in response to evaluation outcomes. Potential collaborators: BLM, BOR, NPS, USACE, USFS, USFWS, USGS, NMED, NMSP, SFD, SLO, universities, local governments, municipalities, non-profit organizations.

Transportation and Service Corridors
Identify or develop an accessible, jointly used database to document the status and condition of, threats to, and conservation actions implemented across aquatic, riparian, and upland habitats. Identify data gaps (e.g., Ganey et al. 2017) and implement standardized methods to gather habitat data (e.g., Vollmer et al. 2018, Shirk et al. 2023) and to monitor the success of conservation actions (e.g., Davis and Pinto 2021), including impacts on local SGCN populations. Synthesize existing information (e.g., Jain et al. 2021) and apply modeling techniques to aid in evaluating success when appropriate (e.g., Parks et al. 2018). Adjust future conservation actions as needed based on observed outcomes. Potential collaborators: BLM, BOR, NPS, USACE, USFS, USFWS, USGS, NMED, SFD, SLO, universities.

Transportation and Service Corridors
Site, consolidate, and maintain utility corridors to minimize adverse effects to SGCN and their habitats. Reduce avian powerline collisions by using line markers and illumination with ultraviolet lights and by burying powerlines (Bateman et al. 2023). Avoid mowing rights-of-way during peak SGCN pollinator larvae abundance and avoid mowing patches of nectar resources important for pollinator SGCN (e.g., Xerces Society 2018). Potential collaborators: BLM, DOD, USFS, SLO, interested and affected members of the public, local governments, utility companies.

Transportation and Service Corridors
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). Potential collaborators: BLM, NPS, NRCS, USFS, SFD, SLO, energy and mining companies, non-profit organizations, private landowners, Tribal natural-resource managers.

Transportation and Service Corridors
Work with appropriate agencies to develop and enforce road-management plans (Crist et al. 2005). Potential collaborators: BLM, USFS.

Transportation and Service Corridors
Work with collaborators to complete mitigation measures that will increase the probability of safe passage across roads and near utility lines for affected SGCN. These include modifying barrier fences along roadways, constructing road crossings, placing warning signs for motorists, marking utility lines so they can be readily seen by birds, and placing safeguards that will reduce the probability of electrocution. Integrate benefits to SGCN in projects primarily designed and implemented to enhance safe passage for large mammals (e.g., projects implemented under the Wildlife Corridors Action Plan) (Cramer et al. 2022). Monitor the efficacy of mitigation measures and initiate any identified maintenance and improvements. Potential collaborators: BLM, DOD, USFS, NMDOT, SLO, private landowners, utility companies, Tribal natural-resource managers.
