Seasonality

No dated California records from 2000 to 2026.

California has no dated Townsend’s vole records from 2000 to 2026, which leaves nothing recent to place on a county list or a monthly calendar.

This large, dark vole of wet meadows, tidal marshes, and coastal grassland ranges from Washington through Oregon, and the far northern California coast marks the southern edge of its US range. A vole that keeps to dense grass runways is easy to overlook, and the empty window says more about how seldom anyone has documented it here than about whether it still occurs.
