AbstractShrub encroachment into rangelands is a concern for livestock producers. A study was conducted to determine whether targeted grazing with small ruminants could be used to suppress one-seed juniper sapling growth. Since most domestic ruminants avoid feeding on juniper, this study focused on approaches to boost shrub browsing intensity to levels that would kill or cripple sapling growth without permanently damaging the grass understory. We tested use of goats or mixed species (goats plus sheep) during two periods of growth (summer and spring) at two stocking densities (10 and 60 m2/AU/day) with two replicates per treatment. Animals tended to strip needles and thin stems from young saplings, whereas impacts on older saplings consisted mainly of bark stripping. Mixed species high-density stocking resulted in the fewest tall saplings (> 1 m) in the low utilization category ( 66% of branches defoliated), and the fewest saplings with low (
