Comments:Stands of this series can have nonnative, annual species mixed with the perennial grasses and herbs. Soft chess is common. However, introduced species are not as important in this series as in other needlegrass series. If the stand occurs on ultramafic arent materials, serpentine species-adapted are common. Foothill needlegrass, nodding needlegrass, and purple needlegrass grow sympatrically but do not typically mix, especially in SoCo. They tend to segregate based on substrate and slope factors [ see Nodding needlegrass series and Purple needlegrass series]. In the ecological literature foothill needlegrass is referred to as Stipa lepida . The Jepson Manual places foothill needlegrass in the genus Nassella .
Plot based descriptions:Kellogg & Kellogg (1990, 1991) present unclassified plot data on areas dominated by foothill needlegrass, nodding needlegrass, or purple needlegrass at Pendleton Marine Corps Base in San Diego Co. o-SoCo; Boyd (1983) describes a stand in Gavilan Hills i Riverside Co. i. m-TraR; Keeler-Wolf (1990a) foothill needlegrass-dominated stands at King Creek RNA in San Diego Co. m-PenR.
