A pocket gopher is almost never seen whole, and this one is no exception. Most of the 407 California records are fresh dirt mounds or a whiskered face at a burrow entrance. Nearly all come from iNaturalist photographs, and the GBIF specimen side of the state record is empty. Public photos are doing nearly all the documenting here.
Sonoma County accounts for well over half the reports, 241 of them. Humboldt and Mendocino add smaller clusters along the North Coast, with a light scatter inland through Napa, Solano, and Yolo. Sugarloaf Ridge State Park is the single most reported site. That says as much about where North Bay naturalists hike as it does about gopher density. Records run through the year, with a modest rise in April and May when damp spring soil brings digging close to the surface. Don’t read the county gaps as absences. A burrowing rodent is easy to overlook where nobody is counting.
