California is currently home to one known gray wolf pack.
California had no known gray wolves within the state until OR-7, originally from the Imnaha Pack in NE Oregon and now breeding male of the Rogue Pack in Southern Oregon – traveled into the state for a period of time during parts of each year from 2011-2014. The last known wolf before OR-7 was trapped and killed in Lassen County, CA in 1924. Gray wolves are protected state-wide by the California Endangered Species Act.
