Article abstract: Alien plants were a substantially greater threat in the immediate postfire year on sites burned twice, in 2003 and 2007. Comparing post-fire recovery in 2003 fires with recovery on the same sites after the 2007 fires, alien density and cover were substantially greater in 2007. These results illustrate an important threat to native community integrity in San Diego County due to repeat fires and attention needs to be paid to how to reduce disturbance frequency on wildland landscapes.
