State 1
Reference State
Description
This state is the reference state for this ecological site. It is defined by an E type Rosgen channel.
Submodel
Description
This state is characterized by unstable, entrenched G and F type channel types.

Mechanism
This transition occurs when the E and C type channel equilibrium is disrupted. This may be triggered by the loss of channel stabilizing vegetation, either from physical trampling or hydrological alterations that cause the water table to lower and subsequently cause a decline in the stabilizing vegetation. Manipulations such as channel straightening, confining the floodplain, or improperly designed road crossings can also trigger this transition.
Mechanism
Restoration practices to restore channel conditions to state 2, vary depending upon site specific conditions. Removal triggers may allow these streams to stabilize over time. If livestock grazing is permitted in these areas, it would be best to keep them out of the wettest areas of the meadow. Trail and Road networks should be designed so they do not alter the hydrology by collecting or concentrating flow in a channel. Channel redesign may be necessary in some areas to increase channel meander, raise the channel bed level, and reconnect flows with the floodplain.
Mechanism
This transition occurs when the F channel has widened sufficiently to allow for a C channel type to develop with a lower, re-established floodplain.
