Lassen’ antelope bitterbrush is recommended for restoring depleted rangelands, burned areas, mined lands, and other disturbed sites in the Intermountain West. Lassen was selected for its seedling vigor, upright growth habit, seed production, productivity, and retention of overwintering leaves. Selection trials indicate Lassen is adapted to antelope bitterbrush sites receiving 300 to 600 mm of precipitation at elevations ranging from 900 to 1,800 m. Best growth occurs on deep, coarse, well-drained, neutral to slightly acidic soils. Productive Lassen plantings have been established on such sites in northeastern California, eastern Oregon, and central and southern Idaho.
