Calhoun Cut Ecological Reserve was designated as an ecological reserve by the Fish and Game Commission in 1993. There are at least three main habitat types present on the approximately 1,200-acre reserve: valley riparian, valley needlegrass grassland, and northern claypan vernal pools. The most apparent type of wildlife use is by ducks, primarily mallards, geese and wading birds wintering in the rich freshwater marshlands located on the property and feasting on seasonal invertebrate populations in the vernal pools. These invertebrates include federally-listed species of fairy and tadpole shrimp.
