Arrangement of no spring grazing (NG), limited spring grazing (SG), and extended spring grazing (SG+) treatments in paddocks of smooth bromegrass, pubescent wheatgrass, and orchardgrass at Marshall, OK. Location 1 and Location 2 correspond to those paddocks described by Reuter and Horn (2002). Not to scale. R = replication.
