Description
The Current Potential State is similar to the Reference State except the plant communities have non-native species present. The presence of non-native species, especially those that are invasive, lowers the resistance and resiliency of the state. Invasive/non-native plants that can come in with a high water table are meadow foxtail (Alopecurus arundinaceus), quackgrass (Elymus repens), reed canarygrass (Phlaris arundinacea), and Kentucky bluegrass (Poa pratensis). These species are also more tolerant of grazing and can increase and may become dominant on the site.

Description
The Degraded/Lower water table State develops after a permanent lowering of the water table. This can occur from excessive grazing that can cause meadow downcutting or through artificial meadow drainage to decrease soil saturation. State 1 and State 2 can transition to this state. The site has crossed the threshold. This state cannot be returned to State 1 without raising the water table.
Submodel
Mechanism
This transition can occur with artificial drainage of the site, which reduces the availability of water and reduces soil moisture.
