The complete county distribution, spread across 16 California counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

American pika reporting in California is tightly concentrated in summer. June through September account for most of the 1,638 records, led by July and August, while every winter month remains in the low double or single digits.

The three suggested places in the file are wildlife refuges, but none has a supporting place count, so they cannot be treated as pika hotspots. The strong summer curve may reflect access, weather, and observation effort alongside pika activity; it records when sightings were submitted, not how many animals occupy California.
