Mechanism
This transition pathway can occur as a result of any disturbance that directly impacts an existing forest tree canopy. Examples include abnormal flooding events and/or changes to hydrology which cause increased duration and depth and flooding, increased flood energy and scour, deposition of significant flood transported material, ice, wind, insects, disease, and timber extraction.

Mechanism
This transition pathway can occur as a result of any disturbance that directly impacts established woody vegetation including both trees and brush. Examples include abnormal flooding events and/or changes to hydrology which cause increased duration and depth and flooding, increased flood energy and scour, deposition of significant flood transported material, ice, wind, insects, and disease
Context dependence
Some wildlife habitat management objectives (or other objectives) might call for the reduction of woody vegetation and the enhancement of herbaceous meadow vegetation, so this transition can potentially be a restoration as well.

Mechanism
This transition pathway can occur as a result of any disturbance that changes hydrology and creates increased depth and duration of ponding of water on the soil surface.

Recovery would require significant hydrologic restoration

Mechanism
This restoration pathway is a normal successional pathway that can occur in the absence of high-energy flooding with scour, in the absence of flooding with high rates of deposition, and with a stable hydrologic regime. The normal successional pathway on these sites is towards wet forest conditions. Soil and hydrologic conditions may resist succession, even for long periods of time. However, shrubland conditions ultimately create an increasing abundance of microsites suitable for the recruitment of trees. Some type of tree killing disturbance is typically necessary to reverse that trend of increasing tree cover.

Mechanism
This restoration pathway is a normal successional pathway that can occur in the absence of high-energy flooding with scour, in the absence of flooding with high rates of deposition, and with a stable hydrologic regime. The normal successional pathway on these sites is from wet meadow to wet shrubland and ultimately towards wet forest conditions. Soil and hydrologic conditions may resist succession, even for long periods of time. However, wet meadow conditions ultimately create an increasing abundance of microsites suitable for the recruitment of trees and shrubs. Some type of woody vegetation killing disturbance is typically necessary to reverse that trend of increasing woody cover. Some wildlife habitat management objectives (or other objectives) might call for the reduction of woody vegetation and the enhancement of herbaceous meadow vegetation, so some management objectives will be designed to resist this "restoration" pathway.
