CDFW Map 2020

In 1924, California’s last known gray wolf was trapped and killed in Lassen County. California had no known gray wolves since then until OR-7 traveled into the state for a period of time during parts of each year from 2011-2014. OR-7 was originally from the Imnaha Pack in NE Oregon and is now the breeding male of the Rogue Pack in Southern Oregon. Gray wolves are protected statewide by the California Endangered Species Act.
