The purpose of this document is to report the results of a botanical survey of a portion of the Tierra Redonda Mountain Area of Critical Environmental Concern. The survey was conducted for the Bureau of Land Management, and executed between October 2009 and June 2010. Tierra Redonda Mountain is the type locality for the Tierra Redonda formation, and has weathered to form steep slopes of exposed chaparral and protected woodlands. Four general community types were found; foothill woodland, chaparral, southern coastal scrub and dune scrub. Alliances determined by The Manual of California Vegetation (2nd ed.) were: Quercus douglasii Woodland, Quercus agrifolia Woodland, Pinus sabiniana Woodland, Adenostoma fasciculatum Shrubland, Adenostoma fasciculatum—Salvia mellifera Shrubland, Ceanothus leucodermis Shrubland, Eriogonum fasciculatum Shrubland, Arctostaphylos glauca Shrubland, Heteromeles arbutifolia Shrubland, Ericameria ericoides Shrubland and Achnatherum speciosum Herbaceous Alliances. A total of 242 species were identified in the survey area, most with a respective voucher specimen housed in the Robert F. Hoover Herbarium (OBI) on the Cal Poly, San Luis Obispo campus.
