Our objective was to evaluate effects of fire, grazing, and clone size on response of Bouteloua eriopoda (black grama) in southern New Mexico. Small, medium, and large clones were mapped in five 0.91-m2 quadrats prior and two years following fire and grazing treatments. Maximum fire temperature at ground level was measured as an estimate of fire intensity. Our results showed that almost all responses were independent of grazing. Basal and canopy cover, recruitment, and clone basal area decreased with increased fire temperatures. Fire did not kill clones regardless of size. Surviving clones resprouted rapidly following fire that was likely influenced by above-average precipitation, We conclude that additional studies are needed under different weather conditions.
