Submodel
Description
This state consists of forest canopy openings that are created by catastrophic disturbances, allowing sunlight to reach understory strata and ground surfaces. Depending on local conditions and disturbance regime and intensity, a continuum or range of successional stages and community structure (physiognomy) is represented. Provisionally, this state includes seral stages ranging from recent disturbances that consist mainly of sparse herbaceous cover over mostly bare soil to the regeneration of woody species among a dense herbaceous cover (early stand initiation stage) to the initial stem exclusion stage where woody growth overtops and shades out the herbaceous stratum. In future ecological site development efforts, multiple community phases that describe the composition and progression from one stage to the next may be warranted for specifying management strategies and actions.

Catastrophic river change in channel (AVULSION)
Submodel
Description
The natural processes of the development of the alluvial plain include the transition of frequently flooded areas accumulating sediment and reduction of the depth and duration of flooding and ponding with changes in hydrology. Over time species will transition to species that are better adapted to the dryer site conditions and will begin to dominate. These transitions will occur over long periods of time and will be very gradual. Alternatively, with the anthropogenic alterations to the sites of the alluvial plain drainage improvements will allow for the transition of the site similar to the natural processes.
