types of marshes

types of marshes

Some of the more prominent types found in Wisconsin are listed below. Articles from Britannica Encyclopedias for elementary and high school students. Recently, bogs have been recognized for their role in regulating the global climate by storing large amounts of carbon in peat deposits. These three can be found worldwide and each contains a different set of organisms. Tidal marsh along the Edisto River, South Carolina. Fens, like bogs, provide important benefits in a watershed, including preventing or reducing the risk of floods, improving water quality and providing habitat for unique plant and animal communities. Spike grass (Distichlis spicata) i… Wet Meadows. The soil itself is a mixture of peat and sand containing large amounts of charcoal from periodic burnings. Water levels in these wetlands generally vary from a few inches to two or three feet, and some marshes, like prairie potholes, may periodically dry out completely. Marshes, swamps, and bogs are all types of wetlands. Non-tidal marshes are the most prevalent and widely distributed wetlands in North America. They can sustain a vast array of plant communities that in turn support a wide variety of wildlife within this vital wetland ecosystem. Larger depressions were occupied by ponds. The Greater Sandhill Crane, the Sora Rail, and the Great Gray Owl depend on bogs for survival. Crown is dark and eyebrows are white. Tidal marshes are normally categorized into two distinct zones, the lower or intertidal marsh and the upper or high marsh. These gradually became marshy as they filled in with sediment. Most such areas are drained someplace along their rim by a river that is impeded at that point sufficiently to dam water at times of high flow and create marshes and swamps. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Mangrove swamps are a type of shrub swamp dominated by mangroves that covers vast expanses of southern Florida. Because of the large historical loss of this ecosystem type, remaining fens are that much more rare, and it is crucial to protect them. Tidal marshes also provide vital food and habitat for clams, crabs and juvenile fish, as well as offering shelter and nesting sites for several species of migratory waterfowl. In this system, wetlands are classified by landscape position, vegetation cover and hydrologic regime. Fens, are peat-forming wetlands that receive nutrients from sources other than precipitation: usually from upslope sources through drainage from surrounding mineral soils and from groundwater movement. Freshwater marshes are characterized by periodic or permanent shallow water, little or no peat deposition, and mineral soils. Common cattail is commonly found growing on the edges of freshwater marshes where the water is shallower. The presence of marshes in a watershed helps to reduce damage caused by floods by slowing and storing flood water. In Classification of Wetlands and Deepwater Habitats of the United States (1979), the USFWS presented a hierarchical system based on five ecosystem types: marine, estuarine, riverine, lacustrine, and palustrine. Also like the bogs of the far north, pocosins are found on waterlogged, nutrient poor and acid soils. Some pocosins are very large and difficult to develop, and so they remain largely undisturbed. Tidal marshes can be found along protected coastlines in middle and high latitudes worldwide. Marshes are defined as wetlands frequently or continually inundated with water, characterized by emergent soft-stemmed vegetation adapted to saturated soil conditions. As the title implies, wetlands are classified by their geomorphic setting, dominant water source (e.g. Swamps are characterized by saturated soils during the growing season and standing water during certain times of the year. The word pocosin comes from the Algonquin Native American word for "swamp on a hill." These are open, exposed areas that can easily fall victim to storm surges or changes in sea level. Over time, peat may build up and separate the fen from its groundwater supply. Common cattails (Typha latifolia), sometimes called North American cattails, are a common type of marsh grass. As the tide flows out, this water drains away. Bogs in the United States are mostly found in the glaciated northeast and Great Lakes regions (northern bogs) but also in the southeast (pocosins). Historically, swamps have been portrayed as frightening no-man's-lands. Oregon has many wetland types that range from tidal salt marshes along the coast to fresh water marshes along streams and ponds, seasonal prairie and meadow wetlands in the valleys to mossy mountain fens. Fens, like bogs, are peatlands, but because they are fed by groundwater they are not so acidic as bogs. The highly organic soils of swamps form a thick, black, nutrient-rich environment for the growth of water-tolerant trees such as Cypress (Taxodium spp. Classification of Wetlands and Deepwater Habitats of the United States, A Hydrogeomorphic Classification for Wetlands. Swamps tend to have a larger proportion of surface water than marshes and, in North America, are characterized by the presence of trees. Let us know if you have suggestions to improve this article (requires login). A freshwater marsh, dominated by saw grass and dotted by palms and cypresses, in the Everglades, southern Florida, U.S. Salt marsh at Toms Cove, Chincoteague National Wildlife Refuge (within Assateague Island National Seashore), Virginia, U.S. …environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts. There are several that are specific to the Caribbean such as mangroves, lagoons, swamp forests, and freshwater and brackish marshes. Both habitats are linked into drainage systems of three major sorts: exorheic, endorheic, and arheic. It is important to recognize that while mining and draining these ecosystems provide resources for people, up to 10,000 years are required to form a fen naturally. Swamps are home to variety of animals like snakes, bobcat, alligators, beaver, large diversity of birds. major types of wetlands found in the United States organized into four general categories: marshes, swamps, bogs, and fens.! Wet Prairies. Over time, many feet of acidic peat deposits build up in bogs of either origin. Sawgrass marshes are usually flooded with water for most of the year. Tail is relatively short and dark-barred. Northern bogs often form in old glacial lakes. The most common plants are evergreen trees (Loblolly Bay, Red Bay and Sweet Bay), and evergreen shrubs (titi, fetterbush and zenobia). Pollution, especially near urban areas, also remains a serious threat to these ecosystems. The gradient of the river approaches zero at the sea, where flow is sluggish. Wetlands are transitional lands between lands and other bodies of water. Contact Us to ask a question, provide feedback, or report a problem. Many are alternately flooded and exposed by the movement of tides. Northern bogs are generally associated with low temperatures and short growing seasons where ample precipitation and high humidity cause excessive moisture to accumulate. There are many different kinds of marshes, ranging from the prairie potholes to the Everglades, coastal to inland, freshwater to saltwater. Moose, deer, and lynx are a few of the animals that can be found in northern bogs. The insects that pollinate it are attracted by its odor, which resembles decaying flesh. Wild rice is of some commercial importance, but true rice is undoubtedly by far the most important marsh plant and supplies a major portion of the world’s grain. Salt marshes, which are extensive along the east coast of the United States and are also common in the Arctic, northern Europe, Australia, and New Zealand, are formed by seawater flooding and draining, which exposes flat areas of intertidal land. Therefore, most bogs in the United States are found in the northern states. Marshes occur in the deltas of the Mekong in Vietnam and the Amazon in Brazil. The number of plant species in marshes is few compared with those that grow on well-watered but not waterlogged land. Because pocosins are found in broad, flat, upland areas far from large streams, they are ombrotrophic like northern bogs, meaning rain provides most of their water. Freshwater Marshes Sediment supplied by the river has often been eroded from the surface soils of the drainage basin and is thus very rich. Legs and feet are black. The hydrogeomorphic (HGM) includes five major wetland types: riverine, slope depressional, flat and fringe. They are busy and vibrant places populated by an intriguing variety of birds that are marsh dependent. Omissions? They are subjected to fire about every 10 to 30 years (Photo by Dr. Curtis Richardson/Duke Wetland Center). These natural fires occur because pocosins periodically become very dry in the spring or summer. Some have been degraded by excessive deposits of nutrients and sediment from construction and farming. Fortunately, most states have enacted special laws to protect tidal marshes, but diligence is needed to assure that these protective measures are actively enforced. This bog in Nova Scotia, Canada is dominated by ericaceous dwarf-shrubs, a common family of plants in the peat bogs of the Northeast. There are two primary ways that a bog can develop: bogs can form as sphagnum moss grows over a lake or pond and slowly fills it (terrestrialization), or bogs can form as sphagnum moss blankets dry land and prevents water from leaving the surface (paludification). Marshes are very similar to swamps . As water moves slowly through a marsh, sediment and other pollutants settle to the substrate or floor of the marsh. Highly organic, mineral rich soils of sand, silt, … Bogs support some of the most interesting plants in the United States (like the carnivorous Sundew) and provide habitat to animals threatened by human encroachment. Such environmental problems prove the vital roles these wetlands play. The soils are alkaline because of the limy base, and the water is clear. Nevertheless, bogs support a number of species of plants in addition to the characteristic Sphagnum Moss, including Cotton Grass, Cranberry, Blueberry, Pine, Labrador Tea and Tamarack. The Cowardin system includes five major wetland types: marine, tidal, lacustrine, palustrine and riverine. The Great Egret (Casmerodius albus) winters in the tidal marshes along the Gulf Coast. The combination of water supplied steadily at a low rate over a waterlogged but rich soil creates a perfect environment for marsh grasses. In Europe well-known river-mouth marshes include those of the Camargue in the Rhône Delta, the Guadalquivir in Spain, and the Danube in Romania, all of which are famous as bird sanctuaries. Marshes are what come to mind for most people when they think of a wetland. Swamps serve vital roles in flood protection and nutrient removal. When this happens, the fen receives fewer nutrients and may become a bog. Types of Wetlands. As a result, bogs are low in the nutrients needed for plant growth, a condition that is enhanced by acid forming peat mosses. The area is an ideal marsh habitat, but the Everglades is different from usual marshes. and Western Hemlock (Tsuga sp.) Salt marshes are among the most productive natural systems. Historically, pocosins were mostly threatened by agriculture. Shrub swamps are similar to forested swamps except that shrubby vegetation such as Buttonbush, Willow, Dogwood (Cornus sp.) Bottomland hardwood swamp is a name commonly given to forested swamps in the south central United States. Both of the great basins named after these rivers have extensive wetlands. Endorheic…. Some fens are characterized by parallel ridges of vegetation separated by less productive hollows. One commonly used classification system for wetlands was developed by Cowardin and is described in Classification of Wetlands and Deepwater Habitats of the United States. Learn about freshwater and salt marshes. Marshes have mostly grasses, while swamps have mostly trees. The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, mire, vernal pool, sink, and many others. The latter characteristic distinguishes a marsh from a swamp, whose plant life is dominated by trees. They are characterized by spongy peat deposits, acidic waters and a floor covered by a thick carpet of sphagnum moss. Severe flooding and nutrient deposition to downstream waters have often followed marsh destruction and degradation. Pocosins are also sources of valuable timber and fuel, but these uses can harm or destroy pocosins if they are not carried out responsibly. Swamps may be divided into two major classes, depending on the type of vegetation present: shrub swamps and forested swamps. Therefore, they are able to support a much more diverse plant and animal community. Marshes North and south of the tropics, swamps give way to marshes. Salt marshes are subject to rapid change, in ecological terms, due to the vagaries of extreme weather events and the behaviour of the sea. This is an especially important function during periods of drought. Mink (Mustela vison), a predator of the muskrat. Exorheic regions are open systems in which surface waters ultimately drain to the ocean in well-defined patterns that involve streams and rivers temporarily impounded by permanent freshwater lakes. The difference between them is the types of plant life they support. As a result, they are a haven for species adapted to living in unaltered forests. Marshes and swamps also both have aquatic vegetation. Many rare species, such as the endangered American Crocodile, depend on these ecosystems as well. Due to the nutrient-rich soils present in swamps, many of these fertile woodlands have been drained and cleared for agriculture and other development. Cattails and open water are common, though bulrush, bur-reed, pondweed, and smartweed are often found in marshes too. Pocosins are densely vegetated with trees and shrubs. Differences in the length of inundation give rise to a variety of community types within this classification. Their acreage declined historically as they were drained to be used as cropland and mined for their peat, which was used as a fuel and a soil conditioner. Sometimes, they are covered by many feet of very slowly moving or standing water. Wetlands are called by many different names and occur in an array of landscapes. Sphagnum creates bogs by holding water and creating acidic conditions. Grasses, grasslike sedges, and reeds or rushes are of major importance. Wetlands can be tidal (inundated by tides) or non-tidal. Prothonotary Warblers (Protonotaria citrea) are found in southern swamplands. precipitation, groundwater or surface water) and hydrodynamics. There are many different kinds of swamps, ranging from the forested Red Maple, (Acer rubrum), swamps of the Northeast to the extensive bottomland hardwood forests found along the sluggish rivers of the Southeast. This Eastern Mud Salamander (Pseudotriton montanus) is resting on sphagnum moss. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Swamps like Everglades in Florida are found in low-lying areas near rivers or coastal areas. They are mostly freshwater marshes, although some are brackish or alkaline. U.S. state agencies also may intentionally flood dry areas to encourage wetland formation to host wetland-dependent species. They are especially important as the last refuge for Black Bears in coastal Virginia and North Carolina and the Red Wolf has recently been reintroduced in North Carolina pocosins. Swamps and marshes can be composed of freshwater, salt water, or brackish water (mix of fresh water and salt water). The same organic matter also acidifies the water. Unfortunately, like many other wetland ecosystems, freshwater marshes have suffered major acreage losses to human development. They are often inundated with floodwater from nearby rivers and streams. A longer hydroperiod along with increased water depths produces taller, thicker stands of sawgrass while a short hydroperiod and shallow waters result in limited growth. Wetlands can form naturally or through animal or human activity. In fact, forested and shrub swamps are often found adjacent to one another. Salt marsh grasses will not grow on permanently flooded flats; growth is also prevented where the flooded land is subject to strong currents and is therefore unstable. The Clapper Rail of the saltmarshes, which is more commonly heard than seen. This article was most recently revised and updated by, U.S Environmental Protection Agency - Marshes, marsh - Children's Encyclopedia (Ages 8-11), marsh - Student Encyclopedia (Ages 11 and up). The world’s two largest rivers, the Amazon and the Congo, fall into this category. In the United States the most extensive delta marshes are those of the Mississippi River. Muskrat (Ondatra zibethicus) next to its house in a cattail-dominated marsh. Marshes and ponds, the edge of a lake or ocean, the delta at the mouth of a river, low-lying areas that frequently flood—all of these are wetlands. These include marshes, swamps and bogs. United States Environmental Protection Agency. The fires are ecologically important because they increase the diversity of shrub types in pocosins. They may have either considerable amounts of open water surrounded by floating vegetation or vegetation may have completely filled the lake (terrestrialization). Home » Topic » Wetlands; Wetland types. Keep in mind that while some marshes may not have open water year-round, their soil is still saturated with water below the soil surface. Get exclusive access to content from our 1768 First Edition with your subscription. They frequently occur along streams in poorly drained depressions and in the shallow water along the boundaries of lakes, ponds and rivers. Productivities of more than 3,000 grams per square metre per year have been reported for the most productive parts of salt marshes, the tall Spartina alterniflora stands growing along tidal creeks. Scientists distinguish dozens of wetland types, characterized by vegetation, soil type and degree of saturation or water cover. Bogs receive all or most of their water from precipitation rather than from runoff, groundwater or streams. Fens may be dominated by woody or herbaceous vegetation. As snow melted, the depressions supported the growth of temporary marshes, which then dried up during the summer. In addition to their considerable habitat value, non-tidal marshes serve to mitigate flood damage and filter excess nutrients from surface runoff. Bogs serve an important ecological function in preventing downstream flooding by absorbing precipitation. The ridges of these patterned fens form perpendicular to the downslope direction of water movement. Marshes are common at the mouths of rivers, especially where extensive deltas have formed. This realization has spurred enhanced protection and restoration of marsh ecosystems, such as the prairie potholes and the Everglades. Plants, birds, fish, and invertebrates such as freshwater shrimp, crayfish, and clams require the habitats provided by swamps. Marshes, bogs, and swamps are typical wetlands. As wetlands, they are all characterized by high levels of biodiversity. Some of the common species of trees found in these wetlands are Red Maple and Pin Oak (Quercus palustris) in the Northern United States, Overcup Oak (Quercus lyrata) and Cypress in the South, and Willows (Salix spp.) Carlisle Bog in Alaska. Tidal Wetlands. Types of Wetlands. They buffer stormy seas, slow shoreline erosion and are able to absorb excess nutrients before they reach oceans and estuaries. Floodplain forests are especially high in productivity and species diversity because of the rich deposits of alluvial soil from floods. Marshes can contain both fresh and saltwater. These systems are often covered by grasses, sedges, rushes and wildflowers. This very pure water is slowly released to estuaries, where it helps to maintain the proper salinity, nutrients and acidity. These semiaquatic or aquatic plants feature pale gray-green leaves and cylindrical brown flower spikes growing on top of 3- to 10-foot-tall stems. Four Types of Freshwater Wetlands. Today, timber harvesting, peat mining, and phosphate mining join agriculture as the biggest threats to the remaining undisturbed pocosins. Some are freshwater marshes, others are brackish (somewhat salty), and still others are saline (salty), but they are all influenced by the motion of ocean tides. A well-known example is the Pripet Marshes and fens that historically have served as the natural boundary between Poland and Russia. As the tide flows in, these wetlands are flooded with water. Both of these factors greatly influence the range and scope of animal and plant life that can survive and reproduce in these environments. Marshes are also common in deltas, where rivers empty into a larger body of water. Some areas, such as the northern Great Plains of the United States, have so many small marshes that they are a characteristic of the landscape. In saline tidal marshes, the lower marsh is normally covered and exposed daily by the tide. Vernal Pools. Tidal wetlands can be found along the shores of the Chesapeake Bay and those rivers and streams that are influenced by the changing tide. Fish and Wildlife Service for the National Wetlands Inventory. Breadcrumb. The Okavango Marshes east of the Kalahari desert in Botswana are perhaps the best example of marshes formed in an interior, closed basin that has no drainage. In the Middle East, both the Nile Delta and the delta of the Tigris–Euphrates have extensive marshes of historical importance. Some low-lying areas with poor drainage at the heads of more extensive drainage patterns contain wetlands. The papyrus marshes of the upper Nile in South Sudan lie above dams of resistant rocks of the cataracts. The soil is often water logged for much of the year and covered at times by as much as a few feet of water because this type of swamp is found along slow moving streams and in floodplains. Different types of salt marshes include open coast, drowned valley, back barrier, deltaic, embayment, and estuarine. Groundwater recharge and discharge:Some wetlands recharge groundwater by holding surface water and allowing it to slowly filter into the groundwater reserves. They typically derive most of their water A swamp is any wetland dominated by woody plants. Saline marshes support a highly specialized set of life adapted for saline conditions. These evergreen shrub and tree dominated landscapes are found on the Atlantic Coastal Plain from Virginia to northern Florida; though, most are found in North Carolina. A marsh is a type of wetland with soil that is rich in minerals. The plants that grow in this area generally have soft stems and are particularly adapted to these wet conditions. The slow movement of water through the dense organic matter in pocosins removes excess nutrients deposited by rainwater. Marshes include tidal marshes along coastal waters, but the only tidal marshes included in this summary are tidal freshwater marshes (those with salinity less than 0.5 ppt). Navigate parenthood with the help of the Raising Curious Learners podcast. It is predominantly covered by the tall form of Smooth Cordgrass (Spartina alterniflora). In aquatic environments, the highest net productivity occurs in estuaries, algal beds, and reefs. The Sweet Pitcher Plant (Sarracenia rubra) is one of the carnivorous plants found in pocosins. and Swamp Rose (Rosa palustris) predominates. Nutrients are plentiful and the pH is usually neutral leading to an abundance of plant and animal life. A marsh is a type of wetland that is often submerged in water. Pocosins provide large tracks of undisturbed land needed by Black Bears (Ursus americanus). The three main types of marsh are salt marshes, freshwater tidal marshes, and freshwater marshes. These values correspond to nearly 30 tons per acre per year and are equal to the highest values that have been achieved in agriculture. in the Northwest. Swamps frequently support highly diverse vegetation because of the many layers of vegetation present: shrubs, saplings, and herbaceous plants. Fibrous-rooted grasses bind the muds together and further hinder water flow, thus encouraging the spread of both the delta and the marsh. The distinction is often made based on the plants and animals that thrive in the area. These wetlands form a flat, grassy fringe near river mouths, in bays, and along coastlines. Forested swamps are found throughout the United States. Some swamps are dominated by shrubs, such as Buttonbush or Smooth Alder. Nontidal marshes are mostly freshwater types, although saline marshes occur in arid and semiarid regions and in areas of land that were once ancient seas or lake beds.
