Listing CNPS List 1B R-E-D Code 1-2-3

State/Federal. Status -- /C2 SCROPHULARIACEAE Jun.-Aug.

Global Rank G2 State Rank S2.2

Distribution: San Diego County, Riverside County, San Bernardino County

Habitat: Montane Meadows and Pebble Pavement Plain are the typical abode of this small, showy annual. Krantz reports this owl's clover at the moist edges of springs and seeps on clay soil in the San Bernardino Mountains. Also utilized are wet meadows and openings in coniferous forest. The soil types at Cuyamaca Lake for the presumed historic population are Holland stony fine sandy loam or Loamy alluvial land.

Known Sites: Botanists have been unable to relocate an historic population near the Stonewall Jackson mine at Cuyamaca Lake. It may be extirpated by cattle grazing. One Data Base report where possibly still extant is from the east face of North Peak 1 mile east of the summit and 0.5 mile west of the junction of Sunrise Highway and Highway 79. Reported by T. Krantz at up to a dozen small populations in Big Bear Valley in the San Bernardino Mountains. Data Base reports from Riverside County are from between Tahquitz and Little Tahquitz Valleys in the San Jacinto Mountains; from San Bernardino County near the edge of a spring and water tank 0.5 mile south of Sugarloaf, at Saragosa Spring in upper Holcomb Valley, at Fawnskin Park, along Highway 38 0.3 mile east of the Junction of Highway 18 near the east end of Big Bear Lake, in Bear Valley in the flats near Bear Tavern, between Arrastre Flat and Union Flat, south of Baldwin Lake about 0.5 mile east of Big Bear Boulevard and 0.3 mile south of Shay Road, at Metcalf in Bear Valley in a meadow at the bay's margin, north of Highway 18 across from the Snow Valley Ski Area, Ash Meadows at Lake Arrowhead, Squints Ranch 4 miles north of Lake Arrowhead, in the meadow at the toll road and public Camp below Lake Arrowhead, in Big Bear City just north of Highway 18 and east of Pioneer Lane, at Deer Lick Station on the east side of Running Springs, at the Northshore Campground at the east end of Lake Arrowhead, 0.3 mile northwest of Woodlands, 0.5 mile east of Bluff Lake, in Maloney Canyon at the east end of USFS Road 3N20, at Harry Spring in Hanna Flat, on the hill slope north of the golf course at Lake Arrowhead, near Eagle Point on the south shore of Big Bear Lake, in the Castle Glen area of Big Bear Lake, in Fawnskin Valley, at Upper Holcomb Valley, the old ski beach at Kidd Cove on the southwestern end of Big Bear Lake, and near Green Valley Lake.

Status: San Bernardino Owl's Clover is close to being extirpated in San Diego County, and is slowly declining elsewhere within its range. Few additional sites are expected to be located in the Cuyamaca area in the southern portion of its range. Significant portions of all substantial populations should be protected.
