Mechanism
Heavy continuous grazing without adequate recovery periods between grazing events will move this plant community across an ecological threshold to the Kentucky Bluegrass Sod/Baltic Rush Plant Community.
Mechanism
Long term prescribed grazing with adequate recovery periods following each grazing event and proper stocking over long periods of time will move this plant community toward the Kentucky Bluegrass/Western Wheatgrass/Trees Plant Community. It may eventually return to the Reference Plant Community through associated successional plant community stages assuming an adequate seed/vegetative source is available. This process may take greater than 20 years.

Mechanism
Excessive defoliation (i.e., areas of heavy animal concentration) or cropped go-back land with continuous grazing will convert the plant community to the Annual/Pioneer Perennial Plant Community.
Mechanism
Under long-term prescribed grazing and removal of disturbance, including adequate rest periods, this plant community will move through the successional stages, and may eventually lead to the Big Bluestem/Switchgrass/Prairie Cordgrass Plant Community. Depending on the slope, aspect, and size, and if adequate perennial plants exist, this change can occur more rapidly. This process will likely take a long period of time (25+ years).
Range seeding with deferment and prescribed grazing can convert this to a plant community resembling the Big Bluestem/Switchgrass/Prairie Cordgrass Plant Community.
