differs from the sage scrub by being evergreen. Along the northern slopes, especially in the cracks and valleys, one can find coast oak and Southern California black walnut woodlands. Southern California black walnut woodlands are increasingly rare and threatened. The largest strands of this community are in the San Jose Hills and Puente Hills to the south. Mammals, birds, reptiles, and amphibians are very diverse in both the San Jose Hills and surrounding San Gabriel Valley. Mammals in the San Jose Hills include bobcats, coyotes, gray fox, skunks, opossums, squirrels, and other rodents. The bird diversity is exceptional, and notable species include California quail, least Bell's vireo, coastal California gnatcatcher, grasshopper sparrow, southwest willow flycatcher, and red-tailed hawk. Reptiles and amphibians include various lizards and snakes, the California red-legged frog, southwestern arroyo toad, southwestern pond turtle, and other frogs and salamanders. Culture and recreation On the most northeastern border, Fairplex (Los Angeles County Fairgrounds) offers an annual L.A. County Fair and other events throughout the year. Fairplex is also the location of both the Los Angeles County Railroad Museum and the Wally Parks NHRA Motorsports Museum. Automotive racing enthusiasts can enjoy adjacent Pomona Raceway-Dragstrip. Two parks with significant natural areas are located in the eastern portion of the San Jose Hills; Ganesha Park include four picnic pavilions, a community center, amphitheater style band Shell, Olympic size swimming pool with slide, basketball courts, two lighted tennis courts, wildlife and hiking areas, and restroom facilities. Frank G. Bonelli park has Puddingstone Lake used for swimming, water skiing, wind surfing, and sailing. The lake is also stocked with trout, bluegill, catfish, and large-mouth bass. Raging Waters, a water theme park, is located at the north end of the lake. There are boat rentals, hot tubs, an equestrian center and a wedding chapel. Bonelli park facilities include vehicle camp sites, trails for hiking, biking and horseback riding, play equipment, gazebos, and group rental picnic areas. East of Bonelli park is Mountain Meadows Golf Course, and on the west, Via Verde Country Club, the later that is south of Walnut Creek Park, a small park along Walnut Creek (which drains both Puddingstone and nearby San Gabriel Mountains into the San Gabriel River). Several large institutions of higher education are located in the hills. These include the California Polytechnic State University, Pomona (Cal Poly Pomona); Mount San Antonio College (Mt. SAC), and Pacific West Bible College.
