Expedition 2000 to Isla Guadalupe
A Binational Multidisciplinary Expedition

Scientists from the Museum's Biodiversity Research Center of the Californias embarked on a binational multidisciplinary expedition to Isla Guadalupe, off the coast of Baja California, on 3 June 2000. The major purpose of this project is to survey and assess the current status of the island's flora and fauna, which have been severely disturbed by introduced non-native goats, dogs, cats, and rodents. By landing a helicopter on the previously unexplored sheer-rock islet off the southern coast, Islote Adentro, the researchers will be able to compare pristine, undisturbed conditions with those of the main island.

Another important focus of this expedition is the search for the Guadalupe Storm-Petrel (Oceanodroma macrodactyla), an elusive nocturnal sea bird thought to be extinct. There is reason to believe that this bird, not seen since 1912, may indeed still be extant. Researchers from the Museum, Mexican universities, conservation organizations, and governmental agencies, representing disciplines of ornithology, botany, entomology, herpetology, paleontology, and ecology will participate in this expedition. Partial funding from the National Science Foundation has been awarded, and additional support is being sought.
