Flora of the San Jose Hills.

The San Jose Hills are part of an important wildlife corridor between the Peninsular Ranges and the Transverse Ranges of Southern California. Over the last few centuries, the natural areas of the San Jose Hills have been greatly reduced; initially because of agriculture and more recently due to urbanization. However, there remain continuous stands of the increasingly rare native coastal sage scrub, riparian, and woodland communities; in fact, the presence of the threatened Southern California black walnut (Juglans californica) woodland habitat and breeding grounds for the California Gnatcatcher (Polioptila californica) have resulted in much of the Hills being recognized as a Significant Biological Area. The purpose of this study is to create and catalogue herbarium vouchers, which will be housed in the Cal Poly Pomona Herbarium (CSPU), and create a vegetation map and manual for the Flora of the San Jose Hills.  
Currently, voucher samples are being collected in all areas of the San Jose Hills and identified using dichotomous keys; the location and habitat of each specimen is also recorded. Vouchers are mounted and preserved so they can be used as representative specimens. To this point, previously unrecorded species for the flora have increased the collection by approximately 2%. In addition to new collections, 285 records of collections in the San Jose Hills have been found through research of the historical collections in the Consortium of California Herbaria.  The records are concentrated mainly in the Voorhis Ecological Reserve (Cal Poly Pomona) and Puddingstone Reservoir and Dam in Bonelli Regional Park, areas which make up only 5% of the total area of the San Jose Hills. Collection of specimens will continue throughout all seasons of the next two years; the catalog of plants will eventually be available to scientists and the general public through the Consortium of California Herbaria.
