Descanso Ranchland (Samataguma Ranch)
The Descanso Ranchland, managed by the San Diego Zoo Wildlife Alliance, is an expansive area committed to fostering biodiversity and ecological research. Spanning nearly 700 acres of undeveloped ranchland, it serves as a field laboratory for conservation science, focusing on the restoration and preservation of native species and their habitats. This project is part of broader efforts to understand and protect Southern California’s unique ecosystems, as it allows for the study and conservation of local flora and fauna.

What is proposed?
The Descanso Ranchland, acquired by the San Diego Zoo Wildlife Alliance (SDZWA) in 2018, encompasses three parcels spread across 669 acres of undeveloped land in southeastern San Diego County near Descanso. This vast area, primarily covered in chaparral vegetation, is dedicated to habitat protection and restoration of Southern California’s native landscapes. The ranchland provides sanctuary for rare and sensitive species, such as 16 sensitive plant species, unique reptiles such as Blainville’s horned lizard, predatory birds, and various small mammals. These species benefit from the undisturbed environment, which supports their survival and propagation.
In addition to its conservation efforts, the Descanso Ranchland serves as a research and educational resource. SDZWA conducts research on the property and also hosts educational programs, including the Biodiversity of Southern California Course, which offers hands-on learning experiences about local biodiversity and conservation strategies.
Project Location
The Ranchland is located in Descanso, California.
Why is this project on the 30×30 list?
The Descanso Ranchlands play a role in achieving the goals of the 30×30 initiative, including bolstering climate resilience, preserving biodiversity, and providing community benefits.
Firstly, the reserve strengthens climate resilience by protecting natural ecosystems from development, which is crucial for carbon sequestration.
Secondly, the Ranchlands’ protected habitats help conserve the biodiversity found within. The Ranchlands’ unique position improves connectivity between agricultural and protected lands, offering a refuge for vulnerable species and maintaining the area’s natural diversity. This connectivity is vital for ecological health and species migration, ensuring a robust natural environment.
Lastly, the area is a hub for research and educational programs, focusing on the unique habitats and biodiversity of San Diego County. These initiatives enhance community understanding and engagement with conservation efforts.
