Groundwater flow in freshwater tidal marshes: a comparison of a natural and a restored marsh. Many more species of plants are able to exist here than in the harsh environment of the salt marsh. However, in every freshwater biome, the temperature decreases with the depth of water. Freshwater marshes are usually found near the mouths of rivers and are present in areas with low drainage.

After fresh water reaches the ground through precipitation, it flows downhill across a landscape called the watershed to lakes, ponds, rivers, streams, and wetlands. SUBSTRATE: Peat in deep-water marshes with long hydroperiods; marl or sandy in marshes with moderate to short hydroperiods and seasonal drying. The two categories of freshwater marshes include tidal freshwater marshes and inland freshwater marshes. Although seed dispersal is assumed to be a major factor determining plant community development in restored wetlands, little research exists on density and species richness of seed available through dispersal in these systems.

Freshwater Marshes might be called mud holes with plants in them.) Freshwater marshes are a type of wetland that is teeming with both animal and plant life. Since June 2008, in situ manipulations in a Zizaniopsis miliacea (giant cutgrass)-dominated tidal freshwater marsh in South Carolina have raised porewater salinities from freshwater to oligohaline levels and/or subtly increased the amount of water flowing through the system. The freshwater marshes are also characterized by animals living in the water, on the surface of the water, above water, and on the spongy areas surrounding the swamp on land. Some of these plants also grow at the upland margin of salt marshes where fresh water drains or collects. TOPOGRAPHY: Low, flat, poorly drained. Marsh grasses, also called cord grasses, are soft-stem, coarse plants that have adapted to thrive in soil that is continuously saturated.
