Supporting Integrated Tree Conservation in Baja California Sur, Mexico

Supporting Integrated Tree Conservation in the Cape Region, Baja California Sur, Mexico

Partner: Unión de Conservación Agua de la Sierra (UCAS) / International Community Foundation (ICF)
Years: 2025-2028

This project aims to improve the conservation status of eight rare native tree species in the Sierra de la Laguna, Baja California Sur, Mexico. Seven of these trees are listed by the IUCN, seven are endemic to the Cape region of the state, and one is federally listed as endangered.

Jatropha vernicosa

Led by the Unión de Conservación Agua de la Sierra (UCAS), this project is establishing a community-managed nursery to propagate seedlings from locally collected seeds, develop species-specific propagation protocols, and implement strategic reintroductions in protected and restored habitats. The following species benefit: Diospyros californica (VU), Esenbeckia flava (VU), Jatropha vernicosa (VU), Nahuatlea arborescens (VU), Quercus brandegeei (EN), Quercus devia (EN), Sideroxylon peninsulare (EN).
The initiative also documents population-level data and threats for target species, produces a bilingual propagation manual, and trains local landowners and workers in restoration techniques. Building on previous work and supported by local and academic partners, this three-year effort combines in situ and ex situ conservation actions (60% and 40%, respectively) to address recruitment failure caused by grazing and habitat degradation.
The project aligns with regional conservation priorities and offers a replicable model for threatened tree recovery across northwestern Mexico. Strong community engagement, existing infrastructure, and a network of committed collaborators provide a solid foundation for long-term sustainability.
