If you allow animals to graze more than 60% of the plant leaf volume of pasture plants, you’ll stop 80% to 100% of root growth.
If you move grazing animals to the next paddock when 40% to 50% of the total leaf volume of plants is consumed, you will lose only 5% of root growth. Such prescription grazing can help current species thrive.
However, does this common prescription of “take half, leave half” reduce cool-season invasive species like Kentucky bluegrass, smooth brome or crested wheatgrass?
The short answer: not everywhere. Prescriptive grazing can increase invasive species….
