Vagrant shrews are recorded in California’s moist mountain meadows, stream margins, and damp forest floors. Yosemite, Sequoia National Forest, and the Lake Tahoe region all provide cool upland settings, but the useful habitat is the wet ground within them rather than the mountain scenery alone.
Reports rise from spring into a clear July peak, then remain fairly strong through September. Field surveys are easier during the snow-free season, so the summer concentration may say as much about access as shrew activity. Records in every month show continued documentation, not equal visibility or abundance across the year.
