We search and we research. Our scientists, along with peers in both the United States and Mexico, conduct biological expeditions and other field research in some areas of southern California and throughout the Baja California Peninsula. Expeditions, like much of the research the Museum does, center around the very simple question, “What lives where?” Although simple, the question is fundamental to biodiversity conservation. What to save? Where to save it?
The data we collect are often used by local citizens and organizations to inform conservation efforts. In many of these areas, the biodiversity is incredible, yet not well documented. One expedition at a time, we attempt to fill in those voids and contribute to the conservation of some of the most amazing places on Earth.
For two weeks in November 2018, 25 scientists and volunteers visited 15 different islands in the southern portion of the Gulf of California to gather information on the status of terrestrial biodiversity of these islands. They documented a remarkable number of new records for the islands: 114 new plant records, 2 new herpetological records, and at least a dozen entomological records. More.
In 1908 the Museum of Vertebrate Zoology at Berkeley mounted an expedition to the San Jacinto Mountain region, pioneering the exploration of southern California’s biology. On the 100th anniversary of this expedition, the San Diego Natural History Museum began a multi-year study to retrace its path and see how the area’s wildlife has changed over the last century.

We extended our San Jacinto resurvey work to 32 sites in the Mojave Desert region, mostly in Joshua Tree National Park and Mojave National Park. The goal? To understand how the fauna of western North America was transformed by human population growth and land-use changes since it was documented by Grinnell and his team 100 years earlier. Learn more.
The Revillagigedo Islands off the coast of Mexico are known for their unique ecosystem and are now a UNESCO World Heritage Site. In February 2017, a team of international scientists and associates, many from The Nat, spent 21 days on a voyage to these remote islands to document the wealth of terrestrial diversity and evaluate the conservation status of the plants and animals found there.

In November 2017, staff from The Nat worked with partners throughout the regions to conduct a binational multidisciplinary survey of an area known locally as Los Brasileros. This project was a hybrid of recent intensive survey work in the Sierra Cacachilas and a rapid biodiversity survey. More.
In late October 2013, more than 30 researchers, students, and volunteers converged on this small mountain range near La Paz for a binational, multidisciplinary expedition. The expedition team traveled by foot and mule to reach the interior high elevations of the rugged Cacachilas Mountains. Historical collections from the heart of the mountains are very rare, making it a “black hole” of biodiversity information. More.
Isla Guadalupe was once a "Naturalist's Paradise", an outpost humming with biodiversity. Then, 200 years of occupation by humans and invasive species changed everything. Armed with years of historical data and a healthy dose of hope, our researchers ventured back to Isla Guadalupe in 2000 to document the changes, search for lost species, and move the island toward recovery.

This binational, multidisciplinary expedition explored the southern end of the Sierra de La Giganta between Agua Verde and Punta Mechudo. For 21 days, beginning November 5, 2003, approximately 30 scientists from Mexico and the United States conducted fieldwork near Mission Los Dolores and further south at San Evaristo. More.
This was the first major multidisciplinary expedition that the Museum sponsored since the 1960s. The focus of this expedition was two mountain ranges, the Sierra San Francisco and the Sierra Guadalupe, located in northern Baja California Sur on the eastern edge of the Vizcaino Desert. The small amount of scientific documentation previous to this expedition indicated that a biological mosaic of species from both tropical and temperate climates existed in this area. More.
