Description
Riparian forest with frequent flooding and migrating river channel.
Submodel
States 1, 6, 2 and 5 (additional transitions)
1.1. Reference Community (10-30 yrs Post Channel Migration)
1.6. >30 year Post Channel Migration
1.2. Scoured and Unvegetated Channel Deposits
1.5. 1.5 >25 yrs Post Channel Migration: Cottonwood Forest
States 2 and 6 (additional transitions)
1.2. Scoured and Unvegetated Channel Deposits
1.6. >30 year Post Channel Migration
Description
Changes to river hydrology, including dams and levees, have altered community recruitment and succession.
Submodel
Mechanism
This transition is caused by alteration to the stream hydrology including regulation of seasonal flows and the lowering of water tables.
Mechanism
This transition is caused by significant human alterations that force this ecological site over a threshold and change the function and structure of this site in extensive ways.
Mechanism
This restoration pathway occurs only when significant time and money inputs are focused on restoring natural hydrology across an entire watershed.
Mechanism
This transition is caused when invasive species establishment forces this ecological site over a threshold and changes the function and structure in extensive ways.
Mechanism
This transition is caused by significant human alterations that force this ecological site over a threshold and change the function and structure of this site in extensive ways.
Mechanism
This restoration pathway occurs when floodwater removes the topsoil and existing vegetation restoring the site to community phase 2.2 or when significant time and money inputs are focused on removing invasive plants.
Mechanism
This restoration pathway occurs only when significant time and money inputs restore both the hydrologic function and the the ecological function of the vegetation community.
