Rumex longifolius is undesirable in grasslands because it decreases yields and reduces forage feeding value. As a weed of pastures and meadows, the main impact of this plant is to reduce the value of infested land as grazing for livestock. R. obtusifolius is only 65% as valuable as grass as grazing material because of a combination of reduced palatability (and therefore grazing levels) and reduced digestibility.
