Description

Arenaria ursina (Bear Valley sandwort) is a low tufted perennial in the pink family (Caryophyllaceae) endemic to the northeastern San Bernardino Mountains, San Bernardino County, California. This species occurs in a unique habitat called pebble plains (also known as pavement plains). Pebble plain habitat is of limited distribution (occurring only in the San Bernardino Mountains) and supports a biologically rich but highly threatened plant community that consists of small cushion forming plants, minute annuals, grasses, and succulents. Arenaria ursina was listed as threatened by the federal government in 1998.
