Interpretive Summary:

Technical Abstract: Bitterbrush (Purshia tridentata) is a palatable and important shrub for wintering big game on western rangelands. It is difficult to establish, and there is little information on how cattle grazing affects new stands. A 3-year study examined patterns of livestock grazing among young bitterbrush when associated grasses were green and growing or dormant. Early-season grazing increased shrub volume over ungrazed controls while late-season grazing reduced bitterbrush size in all instances. To maximize available browse or foster young stands, cattle grazing should occur early in the growing season and then be deferred after grasses begin to flower.
