San Pedro Mártir Island
A haven for Blue-footed Boobies, Cardon Cactus and Fish-eating Bats in the Gulf of California

San Pedro Mártir is one of the most important seabird islands in the Gulf of California, but its potential is much greater. Since it is the most isolated island in the Gulf, it provides ideal habitat for the Fish-eating Bat, Myotis vivesi, endemic to the Baja California region and is suitable for breeding colonies of storm-petrels, murrelets, and tropicbirds.

Before they were removed, rats introduced to the island had decreased the nesting success of Red-billed Tropicbirds, Brown and Blue-footed Boobies, Yellow-footed Gulls and Heermann’s Gulls. Predation by rats also completely prevented the nesting of Craveri’s Murrelets, Black and Least Storm-petrels, and Fish-eating Bats.
Island Conservation's Role:

In late September and mid October 2007, we successfully removed rats from San Pedro Mártir. The removal of invasive rats is expected to increase plant recruitment, bird nesting success, bat density and distribution, and intertidal diversity and abundance.
Restoration of San Pedro Mártir provided ideal breeding habitat for endemic and native species, such as this Brown Booby.
