Mechanism
This transition is caused by a change to the hydrology that results in increased or decreased water depth. Drivers may include beaver dam impoundment, dredging, mining activity, or other events that cause changes in local hydrology.
Mechanism
This transition is caused by drainage that lowers the water table to the level necessary to grow the selected crop. Practices can include ditching, tile drainage, diversion of water inflows, and removal of woody material.
Mechanism
This restoration is caused by recovery of the hydrologic regime that matches that of the reference state, providing appropriate periods of inundation and water depth for the reference plant community to develop. This may be arrived at with wetland engineering practices, removal of artificial drainage features or diversions, or naturally with the accretion of plant material and sediment over time. In some cases, plant species representative of the reference state may require artificial establishment, especially if invasive species dominate the site.
Mechanism
This transition is represented by drainage that lowers the water table to the level necessary to grow the selected crop. Practices can include ditching, tile drainage, diversion of water inflows, and removal of woody material.
