Because of the altitude (an average of one mile high), areas of plains grasslands and pinyon-juniper-oak woodlands thrive here.
Scattered stands of ponderosa and the more common pinyon pine, mixed with oak and juniper, cover higher elevations. Emory oak, gray oak and one-seed juniper are the most common trees in the park. Emory oak is predominant along Keesey Creek.
Shrubs such as scarlet bouvardia, littleleaf leadtree, trompillo, evergreen sumac, fragrant sumac, Apache plume, little walnut, tree cholla, Torrey yucca, catclaw acacia and agarito grow commonly in the park. Some of these flower abundantly. During wet years, wildflowers fill the park.
Visit our bird blind, which offers an enclosed viewing station, a shielded outside patio, and watering and feeding stations. Or stop by the interpretive center to see what is visiting the bird feeding and watering station there. Scrub jays, white-wing doves, acorn woodpeckers, and rock squirrels are the most frequent visitors.
We regularly see Montezuma quail in the park, outside of their usual western range.
