Description
The Reference State concept has one community phase. Rhizmomatous willow and graminoids are less influenced by seasonal flooding and may remain intact after seasonal flooding. This community is fairly stable, unless there are large floods that deposit or erode bank material.

Description
The Current Potential State occurs after non-native plant species introduction. The species can range from trees, shrubs, to herbaceous. Russian olive, tamarisk, Kentucky bluegrass, and thistles are common non-native plants.
Submodel
Description
The Channelized/Degraded state is characterized by a adjacent stream that has been channelized. Most seasonal floodwaters remain the in channel and do not inundate the flood plain. This may reduce soil moisture and lower the water table on the site allowing species that are more tolerant to dry conditions to establish.

Mechanism
Introduction of non-native species.
Mechanism
Channelization of adjacent stream channel.
