California State Polytechnic University San Luis Obispo Nassella Stands On the grounds of the University in the botanical garden and the Peterson Ranch Unit are found some excellent stands of native grasses. At the botanical garden, which also includes mixed evergreen, chaparral and coastal sage scrub communities, both the Nassella (Stipa) - Vulpia (Festuca) and Nassella pulchra - Yucca whipplei associations occur, the latter being representative of the more xeric conditions of the Valley prairie. In the Peterson Ranch Unit both the Nassella pulchra association, including dwarf plantain, Plantago erecta, and Melica californica, as well as the Nassella (Stipa) - Vulpia (Festuca) association with Vulpia myuros var. hirsuta, Poa sp., Aristida sp., Melica californica and Sisyrinchium bellum, occur. Much of the area on the ridges is serpentine soil with numerous serpentine outcrops. In the gardens there is a stream. Integrity: The ranch unit is grazed, and portions of the botanic garden grassland are being converted to a succulent garden. Use: Research, educational, observational. Ref: Barry, J. W. 1972.
