Description
The Reference State (1.0) represents the best estimate of the natural range of variability that dominated the dynamics of the Wet Subirrigated ecological site prior to European settlement. This site is dominated by warm-season grasses. In pre-European settlement times, the primary disturbances included grazing by large ungulates and small mammals, drought, and a fluctuating water table. Favorable growing conditions occurred during the spring and the warm months of June through August. Today, a similar state can be found in areas where proper livestock use has occurred.

Description
The Native/Invaded State (2.0) is dominated by native and non-native cool-season grasses and grass-like plants. The non-native cool-season grasses are primarily reed canarygrass and in some places creeping meadow foxtail. This state is the result of the invasion of non-native cool-season grasses in combination with continuous grazing, excessive haying, or heavy disturbance. The species that invaded may have also been seeded or escaped from adjacent haylands. The Native/Invaded State (2.0) is very resilient and resistant to change.

Mechanism
The invasion of non-native cool-season grasses in combination with continuous season-long grazing and no recovery opportunity, excessive haying and no recovery opportunity, or heavy disturbance transition State 1.0 to the Native/Invaded State (2.0). Seeding to reed canarygrass or creeping meadow foxtail also transition the Reference State (1.0) to the Native Invaded State (2.0).
