PROTECTION STATUS: Endangered
YEAR LISTED: 1993
RECOVERY PLAN: 1998
RANGE: California’s Ventura, Los Angeles, Riverside, Orange and San Diego counties; and Baja California, Mexico
THREATS: Urban sprawl, agribusiness, off-road vehicles, livestock grazing, wetland draining, invasion of nonnative plants, pollution, fire and fire-suppression activities
POPULATION TREND: The Riverside fairy shrimp is in decline and has the most limited range of any endemic California fairy shrimp. Sometimes Riverside fairy shrimp are overlooked during vernal pool surveys because they hatch out and swim later in the season than many other fairy shrimp, and if they aren’t detected, the pool they live in is often plowed up.
