Wikipedia about: Marshlands electricity
Marshes provide habitat for many types of plants and animals that have adapted to living in flooded conditions. Marshes have extremely high levels of biological production, some of the highest in the world, and therefore are important in supporting fisheries. The pH in marshes tends to be neutral to alkaline, as opposed to bogs, where peat accumulates under more acid conditions.
Types of marshes
Marshes differ depending mainly on their location and salinity. Both of these factors greatly influence the range and scope of animal and plant life that can survive and reproduce in these environments. The three main types of marsh are salt marshes, freshwater , and .
Salt marshes are most commonly found in , estuaries, and on the sheltered side of shingle or sandspit. The currents there carry the fine particles around to the quiet side of the spit and sediment begins to build up. These locations allow the marshes to absorb the excess nutrients from the water running through them before they reach the oceans and estuaries.
Fresh water tidal marshes
This form of marsh is defined by the fact that, although it is a freshwater marsh, it is still affected by the tides. Without the stresses of salinity that are undergone by its salt water counterpart, the diversity of the plants and animals that live in and use these marshes is much higher than in salt marshes. The most serious threats to this form of marsh are the increasing size and pollution of the cities surrounding
