Overview

Shrub-dominated wetlands occurring on mineral or mucky mineral soils that are seasonally or temporarily flooded.

Shrub swamps are common and widespread. They occur in basin depressions, at pond margins, and along river and streamsides. They can be found in any flat area where the water table is at or above the soil surface for most of the year. Soils are generally well-decomposed organic mucks that are permanently saturated but only seasonally or temporarily inundated. Shrub swamps are often found in the transition zone between emergent marshes and swamp forests. More information is needed on their physical characteristics.
