Resting or grazing exclusion can help restore degraded rangelands. A study looked at different resting durations on plant diversity over two years. One-year grazing exclusion increased species richness and diversity under good rainfall. The length of grazing exclusion should depend on the climate and site conditions. Short exclusion with enough rainfall can be a cost-effective way to restore arid rangelands sustainably. Longer resting periods could harm vegetation and put more pressure on remaining grazing areas.
