Extremes of altitude averaging one mile high produce both plains grasslands and pinyon-juniper-oak woodlands. Montezuma quail, usually farther west, are regularly observed in the park. Scattered stands of ponderosa and the more common pinyon pine, mixed with oak and juniper, cover higher elevations. During wet years, the park abounds in wildflowers. Emory oak, gray oak and one-seed juniper are the most common trees in the park. Emory oak is predominant along Keesey Creek. Scarlet bouvardia, little-leaf leadtree, trompillo, evergreen sumac, fragrant sumac, Apache plum, little walnut, tree cholla, Torrey yucca, catclaw acacia and agarito are conspicuous shrubs, some of which flower abundantly.
The interpretive center overlooks the wildlife watering station where scrub jays, white-wing doves, curve-billed thrashers and rock squirrels are among the most common wildlife seen.
