San Joaquin pocket mouse records belong chiefly to the dry grasslands and shrublands of interior California, especially loose soils around the San Joaquin Valley. The listed Mojave parks evoke similar arid ground, but they shouldn’t replace the Central Valley setting carried by the species’ name and records.
April is the busiest month, with March and May forming a strong spring cluster. January and February are nearly empty, and December has few reports. Warmer nights and seasonal small-mammal surveys both improve detection, so this curve shouldn’t be mistaken for a count of the population above ground.
