Transition T1A
Transition T1A is an introduction of non-native species. Also exists in Transition T1A is artificial hydrology alteration, for example, irrigation.
More details -
Transition T1B
Transition T1B is channelization of adjacent stream channel which causes reduced soil moisture and altered hydrology of the site. Urbanization and agriculture use might be present.

Transition T2A
Transition T2A is channelization of adjacent stream channel which causes reduced soil moisture and altered hydrology of the site. Urbanization and agriculture use might be present.

Description
The Reference State concept has two main community phases influenced by time since
disturbance (flooding, fire, etc.) Cottonwood seeds will be left behind after a seasonal flood
event. The cottonwood seedlings will germinate if the soil conditions are right (moist and bare). These seedlings, if left undisturbed, will mature to trees. Understory plants, like rhizmomatous willow and graminoids are less influenced by seasonal flooding and may remain intact after seasonal flooding. Extreme flooding or fire may remove the tree overstory and the understory, allowing the graminoids and willows to dominate the site until the conditions are appropriate for cottonwood establishment.

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 that can establish on this site.
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 reduces cottonwood recruitment and may reduce soil moisture on the site allowing species that are more tolerant to dry conditions to establish.
