Individual leaders of fourwing saltbush were permanently marked and their growth responses monitored during a 3-year study in a shortduration grazing system, a 4-pasture rotation system, and in ungrazed exclosures. Primary and secondary leader growth and numbers of secondaries were responses of interest. Plants continuously browsed by cattle were usually maintained in a hedged form and produced relatively little growth. There was little difference in growth responses between plants in the 4-pasture rotation and the shortduration system when the shortduration rotation cycle was 32 days. However, when the rotation cycle was increased to 64 days, there was a substantial increase of growth for plants in the shortduration system. Plants protected from browsing for 1 year also responded with progressively less leader production as length of protection time increased. We suggest fourwing saltbush plants respond to a 60-day deferment at the beginning of the growing season.
