San Bernardino Kangaroo Rat (Dipodomys merriami parvus), lives in small burrows
Also known as the Four-toed Kangaroo Rat
They are critically endangered in our area due to loss of habitat. There is still some habitat along the edge of the Crafton Hills in the area of Highway 38 near Mill Creek. In the early 1900s they were abundant in the region, until their habitat was wiped out.
