California’s 2019-2020 general tree squirrel season will be open from Saturday, Sept. 14 through Sunday, Jan. 26, 2020. Tree squirrels may be taken only in the open zone during the open season, from between one half hour before sunrise to one half hour after sunset. A map of the state’s tree squirrel hunt zones can be found on the California Department of Fish and Wildlife (CDFW) website, along with the full tree squirrel regulations.
Four types of tree squirrels are game species in California. The Western gray squirrel and the Douglas squirrel are both native to California while the Eastern fox squirrel and the Eastern gray squirrel are introduced and not native to the state. These tree squirrels can be hunted in the open zone during the open season under authority of a hunting license in California. No other validations are required.
A fifth species of tree squirrel, the Northern Flying Squirrel, is not a game species and may not be taken. Flying squirrels are small, native tree squirrels that are seldom encountered due to their nocturnal nature and preference for mature forest habitats with complex canopy structure.
Tree squirrel population levels fluctuate from year to year based on prevailing weather conditions and the annual production of nuts, acorns and seeds for forage.
California received above-average rainfall during 2018-19, with a particularly wet spring season.
“With a return to favorable weather patterns, and good acorn production, there should be ample opportunities to hunt tree squirrels this year,” said Matt Meshriy, an environmental scientist with CDFW’s Upland Game Program.
In recent years, approximately 10,000 to 15,000 hunters have reported hunting tree squirrels annually and their combined statewide bag has ranged from 50,000 to 75,000.
National forests provide some of the best opportunity to hunt tree squirrels in California. Bureau of Land Management lands and CDFW wildlife areas may also provide opportunity for squirrel hunting. Please note that nonlead shot is now required when taking any wildlife with a firearm anywhere in California, so hunters should plan accordingly.
