Western gray squirrel reports in California follow mature oaks and conifers through the Coast Ranges, Sierra foothills, and northern forests. The footprint is much less tied to city parks than records for introduced tree squirrels, though roads and public woodland still receive the most attention.
Observations reach their clearest high point in May and continue in every month. Spring leaf growth, daylight, and time spent on trails can all raise reporting, so the monthly curve isn’t a count of squirrels.
California contributes a large share of the species’ mapped records, which fits its broad western range in the state. Even so, submitted observations can’t show whether one oak woodland holds more animals than another or fill gaps across private forest.
