This study involves sampling terrestrial biodiversity at pitfall arrays at each of the four original pitfall trapping study sites that were sampled after the 2003 wildfires. Additionally, the USGS will conduct surveys at the San Diego Wild Animal Park which burned completely during the 2007 wildfires. This study involves synthesizing what has been learned over the course of a multi-taxa multi-year investigation of the response and recovery of plants and animals to the 2003 and 2007 wildfires in San Diego County.
