Sceloporus exsul is a critically endangered lizard species, endemic to a very restricted area of xerophytic shrublands in central Mexico. For decades, the species remained largely overlooked, with virtually no ecological or population-level information available, raising serious concerns about its long-term persistence. This project aims to secure the survival of S. exsul, conserve its highly vulnerable habitat, and generate conservation benefits for associated endemic species and local communities. Specifically, the project aims to:

1. Confirm the current presence, distribution, and population persistence of Sceloporus exsul through systematic field surveys;
2. Establish baseline ecological and demographic information, including habitat use and population structure, to support informed conservation planning;
3. Assess habitat quality, degradation, and threats within xerophytic shrublands, identifying priority areas for conservation;
4. Collaborate with local communities to promote awareness, stewardship, and sustainable practices that reduce pressure on the species and its habitat;
5. Develop science-based conservation recommendations and a preliminary proposal to designate the species’ distribution area as a locally protected site, in coordination with relevant authorities; and
6. Build local capacity by involving community members and stakeholders in monitoring and conservation activities, ensuring long-term protection of S. exsul and its ecosystem.
