Frequent droughts on range lands in the Great Plains region constitute a major factor affecting the economy of livestock production.More recently attention has been turned to the drought recovery of these grasslands.There is a need of additional knowledge concerning the influence of grazing intensity and season of range utilization on the rate of recovery of specific grassland types.

The objective of this report was to determine the relative rates of drought-recovery of a typical mixed prairie near Fort Collins, Colorado when subjected to two systems of seasonal grazing, 1) Continuous grazing and 2) Deferred grazing.

Deferred grazing appears to speed up drought recovery of all major grasses.Deferred-rotation grazing is suggested as a practical grazing system which permits maximum recovery of drought-stricken, mixed-prairie ranges.
