Map Satellite These steep and eroded bluffs, some 50 meters (170 ft.) high, present a unique combination of plant communities close to a metropolitan area. The south-facing slopes support plants common to the Mojave desert while only a few fast distant on the north slopes are plants common to the San Joaquin Valley and lower Sierra foothills. During the spring, 26 species of flowering plants have been counted in an area 30 meters (100 feet) square. Among the plants found on the bluffs are California poppies, Eschscholzia californica and Eschscholzia lemmonii ssp. kernensis, blazing star, Mentzelia affinis, bladderpod, Isomeris arborea var. globosa, blue fiddleneck, Phacelia tanacetifolia, owl's clover, Castilleja exserta, mustard, Tropidocarpum gracile, and evening primrose, Oenothera deltoides ssp. cognata. Numerous birds have been reported from the area including the red-shouldered hawk, Buteo lineatus, osprey, Pandion haliaetus, and Anthony green heron, Butorides virescens. Integrity: Though many parcels are fenced, portions of the bluffs have suffered at the hands of motorcyclists. Use: Educational, light recreational January 1975
