Pinyon Juniper Woodlands
Extensive stands of pinyon juniper woodlands occur in Yavapai County. Typical stands can be found north of Chino Valley, Ashfork, south of Seligman, and in much of the country between Sedona and Stoneman Lake. These woodlands often produce an under story of blue grama intermixed with side-oats grama, western wheatgrass, and tobosa. Winterfat, cliffrose, and silktassel may be locally abundant. As grass stands become thinner, weeds such as annual goldeneye and clubflower fill in the openings. Snakeweed and threadleaf groundsel may become common. In areas where the pinyon juniper canopy has closed, grasses and herbaceous plants become rare to nonexistent.
