Moderate grazing tolerance except for intense grazing of spring growth. Important for range, watershed, pasture and wildlife improvement projects as well as for revegetation of mining and other soil disturbing activities. Minimum precip. is 8 – 10 inches. Plant fall or spring ½ – ¾ inch deep. 130,000 seeds/lb.
