California Myotis records in California fit woodland, desert canyons, and forest edges.

Reports extend from the north coast through the Sierra Nevada to southern California. They show where people have documented the species, and they don’t rank California’s best habitat.

Reports rise most clearly in Jul–Sep. That pattern can reflect animal movements, weather, and observer effort, so it isn’t a population count.
