Moose, deer, and lynx are a few of the animals that can be found in northern bogs. 836. They tend to … As more and more land is developed in the Eastern United States, pocosins are becoming ever more valuable refuges for wildlife. The insects that pollinate it are attracted by its odor, which resembles decaying flesh. Forested Swamps. According to Wikipedia, “ A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. They are most prevalent in the United States on the eastern coast from Maine to Florida and continuing on to Louisiana and Texas along the Gulf of Mexico. This realization has spurred enhanced protection and restoration of marsh ecosystems, such as the prairie potholes and the Everglades. The ridges of these patterned fens form perpendicular to the downslope direction of water movement. They have mineral soils that are poorly drained and remain wet for part of the year. Pocosins provide important habitat for many animals, including some endangered species like the red-cockaded woodpecker. Headwater Forests generally do not receive overbank flooding from streams like both Bottomland Hardwood and Riverine Swamp Forest wetland types do. This process is important to help maintain healthy fish populations important to both commerce and recreation. This kind of wetland is moist but not flooded, and is found over organic or mineral acidic soils. Headwater Forest wetlands are found throughout the state, from the Coastal Plain to the Mountains. Carolina Wetlands Association’s Annual Giving Campaign continues until December 15th. These marshes can vary greatly in size, depending on their location in the landscape. The presence of marshes in a watershed helps to reduce damage caused by floods by slowing and storing flood water. will consider the role of natural dismrbance , and how they counterbalance competition and succe sion to produce a diversity of wetland types in a land cape. This flooding generally occurs from tides, and, to a lesser extent, groundwater and overland runoff from rain. Technically, these terms apply to different types of wetlands, but the differences are subtle. The influx of freshwater into these wetlands carries fine-grained silt, which accumulates to produce a soft ground surface known as “pluff mud”. In addition to their considerable habitat value, non-tidal marshes serve to mitigate flood damage and filter excess nutrients from surface runoff. Bottomland Hardwood Forests and are found on mineral soils. Tidal marsh along the Edisto River, South Carolina. They are subjected to fire about every 10 to 30 years (Photo by Dr. Curtis Richardson/Duke Wetland Center). A hiker should never venture far into a pocosin without a GPS unit or compass. Hardwood Flats are primarily forested, with broad-leaved trees that drop their leaves in in the fall (deciduous leaves). precipitation, groundwater or surface water) and hydrodynamics. Like most peatlands, fens experienced a decline in acreage at a rate of about eight percent from 1950 to 1970, mostly from mining and draining for cropland, fuel and fertilizer. Hardwood Flat wetlands are found more commonly in the coastal plain in flatter areas between streams (known as interstream flats). Some experts also recognize wet meadows and aquatic ecosystems as additional wetland types. Scattered shrubs include gallberry, blueberry, wax-myrtle, and dangleberry. It is fed mainly by rainstorms and snowmelt, and loses most of its water through seepage and evaporation. These wetlands can also be found in upland areas, particularly in depressions or between … 5,507 (12, 556) Lacustrine. Dense vegetation can quickly turn a pocosin hike into a crawling expedition. Bogs serve an important ecological function in preventing downstream flooding by absorbing precipitation. Basin Wetlands are natural depressions in the earth that are surrounded by uplands, or occur on the edges of small lakes or ponds. Wetland - Wetland - Wetland functions and ecosystem benefits: Wetland functions are defined as the physical, chemical, and biological processes or attributes that are vital to the integrity of the wetland system. Shrub and herb layers in these wetlands can be sparse, especially in areas with very long periods of flooding. A bog can be found on either floodplains or lowlands in the western part of the state, typically within the Blue Ridge Mountains and western Piedmont foothills. Wetlands play a critical role in the ecosystem, as well as provide natural valuable environmental services to our towns and properties.Without our wonderful donors, we would be unable to advocate and educate on behalf of wetlands in the Carolinas. Headwater forests are valuable since they filter pollutants from stormwater runoff that enters them and removes these pollutants before they enter streams. Carlisle Bog in Alaska. Wetlands play a critical role in the ecosystem, as well as provide natural valuable environmental services to our towns and properties. Conclusions. United States Environmental Protection Agency. There are four main types of wetlands based on their location, water salinity, and dominant vegetation. Tidal marshes are normally categorized into two distinct zones, the lower or intertidal marsh and the upper or high marsh. Hydric soils are a wetland indicator. Because Basin Wetlands exist in many forms with variable hydrology, their vegetation can vary widely, ranging from tree species to herbaceous sedges and floating wetland plants (e.g. These wetlands generally have sandy to fine clay based soils. 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. Swamps frequently support highly diverse vegetation because of the many layers of vegetation present: shrubs, saplings, and herbaceous plants. Pine Flats, as defined by NCWAM, are not natural wetlands. Below are brief descriptions of the major types of wetlands found in the United States organized into four general categories: marshes, swamps, bogs, and fens. These natural fires occur because pocosins periodically become very dry in the spring or summer. This wetland type can be found in various sizes, but is less prevalent due to human activity. Non-Riverine Swamp Forest is typically characterized by forest, featuring tree species such as bald cypress, black gum, Atlantic white cedar and loblolly pine. Historically, pocosins were mostly threatened by agriculture. As the title implies, wetlands are classified by their geomorphic setting, dominant water source (e.g. The Convention on Wetlands gives a broad definition to wetlands based on physical and limnological characteristics, which is in turn used as a basis for categories in the Ramsar Classification of Wetland Type. The same organic matter also acidifies the water. Nutrients are plentiful and the pH is usually neutral leading to an abundance of plant and animal life. Bottomland Hardwood Forests are generally flooded for only part of the year and tend to be drier then Riverine Swamp Forests. In order to dissolve solid organic matter anaerobic pre treatment in a septic tank or biodigester is required. All types receive most of their water from surface water, and many marshes are also fed by groundwater. Bogs exist in many forms, from forested to tree-less, from mossy to near bare earth. Freshwater swamps are formed by rivers, streams, or freshwater lakes, and usually occur on flat land around bodies of water where surface runoff is slow and the water table is high. 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. www.ncwetlands.org/wp-content/uploads/NCWetlands.org-wetland-soils-factsheet.pdfIf you wanted something more in depth, here’s a document about Field Indicators of Hydric Soils in the US by the USDA.www.nae.usace.army.mil/portals/74/docs/regulatory/JurisdictionalLimits/Field_Indicators_Hydric_So...If you want to learn about soils with kids, visit www.soils4kids.org/home. Wetland plants, called hydrophytes, are adapted to living in water or on saturated soil all or part of the year. Mink (Mustela vison), a predator of the muskrat. Freshwater marshesare characterized by periodic or permanent shallow water, little or no peat deposition, and mineral soils. Slashed mānuka, Kopuatai Peat Dome. Shrub swamps are similar to forested swamps except that shrubby vegetation such as Buttonbush, Willow, Dogwood (Cornus sp.) Salt and Brackish Marshes also help protect coastal shorelines by slowing currents and trapping sediment, especially during storm events. The Clapper Rail of the saltmarshes, which is more commonly heard than seen. The rain-drenched lands of the UK offer perfect conditions for the formation of wetlands. 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. Fortunately, most states have enacted special laws to protect tidal marshes, but diligence is needed to assure that these protective measures are actively enforced. Hydric soils are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part that favor growth and regeneration of hydrophytic vegetation (these plants have adapted to growing in low-oxygen conditions).Here’s a quick fact sheet about hydric soils from NC Wetlands. 6 — Water storage areas; reservoirs/barrages/dams/impoundments (generally over 8 ha). Floodplain Pools are fed by rain, groundwater, and occasional flooding from a nearby river or stream. Some pocosins are very large and difficult to develop, and so they remain largely undisturbed. All images & media in this story. There are two types of swamps: freshwater swamps and saltwater swamps. Different kinds of wetland are home to different types of plant, depending on 2 main factors: whether the wetlands have mostly fresh, salty or brackish (slightly salty) water; whether the wetlands are always wet or switch between being wet and dry (whether they’re permanent, semi-permanent or ephemeral wetlands). 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. U.S. state agencies also may intentionally flood dry areas to encourage wetland formation to host wetland-dependent species. Tidal Freshwater Marshes are usually characterized by the presence of cattails and other plants such as sawgrass. Riverine Swamp Forests are found throughout the Carolinas but are most abundant in the Coastal Plain region, and can range in size from narrow strips of land to hundreds of acres. Due to the nutrient-rich soils present in swamps, many of these fertile woodlands have been drained and cleared for agriculture and other development. Many Riverine Swamp Forests are found along the wettest portions of large river floodplains. In the Piedmont and Blue Ridge Mountain area, the vegetation in these . The Sweet Pitcher Plant (Sarracenia rubra) is one of the carnivorous plants found in pocosins. Habitat is the most valuable function of Pocosins. Hardwood Flats and Pine Savannahs) will develop into wet Pine Flats when logged. Fens differ from bogs because they are less acidic and have higher nutrient levels. Bottomland hardwood swamp is a name commonly given to forested swamps in the south central United States. Some have been degraded by excessive deposits of nutrients and sediment from construction and farming. As water moves slowly through a marsh, sediment and other pollutants settle to the substrate or floor of the marsh. Some swamps are dominated by shrubs, such as Buttonbush or Smooth Alder. They are generally small in size, typically occur on mineral soils, and remain flooded for part or most of the year. As the tide flows out, this water drains away. Some examples of floodplain wetlands are seasonally inundated grassland (including natural wet meadows), shrublands, woodlands and forests. In the Coastal Plain region, Bald Cypress, Black Gum, and Water Tupelo are more prevalent. These marshes occur on both mineral and organic soils, and they tend to be dominated by herbaceous plants. Forested swamps are found throughout the United States. More fragile wetland types such as mangroves and coral reef, and the unique Dambos in Africa however ought to be given greater attention. A beaver dam can also raise water levels and turn a forested floodplain into this type of wetland. Another common wetland classification system, used by the U.S. Army Corps of Engineers, was developed by Brinson and is described in A Hydrogeomorphic Classification for Wetlands. These storms can produce erratic tidal flooding and salinity levels in these wetlands. Hydric soils are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part that favor growth and regeneration of hydrophytic vegetation (these plants have adapted to growing in low-oxygen conditions). Pine Savannas also provide habitat for the red-cockaded woodpecker, a federally endangered species that nests in the cavities of mature longleaf pine trees. The North Carolina Wetland Assessment Method (NCWAM) was developed  by the North Carolina Division of Environmental Quality specifically for North Carolina and these types are generally recognized in South Carolina as well. This perception led to the vast devastation of immense tracts of swampland over the past 200 years, such as the destruction of more than half of the legendary Great Dismal Swamp of southeastern Virginia. As their name suggests, Floodplain Pools are found throughout the Carolinas in the floodplains of creeks and rivers. Both Salt and Brackish Marshes provide critical nursery habitat for many species of fish, crabs, and shrimp. Historically, lightning strikes and Native Americans would start these fires. The hydrogeomorphic (HGM) includes five major wetland types: riverine, slope depressional, flat and fringe. Floodplain wetlands are not listed as a specific wetland type herein. Natural wetlands with similar hydrology found on interstream flats (e.g. They tend to be wet for only part of the year, and can dry up during the warmer months. The tree canopy is generally composed of pine, as the name suggests. They are characterized by spongy peat deposits, acidic waters and a floor covered by a thick carpet of sphagnum moss. Pocosins are also sources of valuable timber and fuel, but these uses can harm or destroy pocosins if they are not carried out responsibly. They typically do not flood. Wetlands are areas that are filled or soaked with fallen rain (freshwater) or salty sea water. In general, a bog’s vegetation exists in one of two forms: 1) small, grass-like plants with or without tree cover, and 2) tree cover with vegetation clustering in areas exposed to sunlight. They buffer stormy seas, slow shoreline erosion and are able to absorb excess nutrients before they reach oceans and estuaries.

Horizontal subsurface flow constructed wetlands This type of constructed wetland is most commonly used for aerobic post treatment of domestic wastewater and can take a higher hydraulic load than a surface flow constructed wetland. As a result, bogs are low in the nutrients needed for plant growth, a condition that is enhanced by acid forming peat mosses. Basin Wetlands are fed by groundwater, overland runoff, and rain. Swamps serve vital roles in flood protection and nutrient removal. Pine Flats are primarily found in the wide interstream flats of the Coastal Plain ecoregion. and Swamp Rose (Rosa palustris) predominates. They are mostly freshwater marshes, although some are brackish or alkaline. In this system, wetlands are classified by landscape position, vegetation cover and hydrologic regime. 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. As a third key factor, f . Highly organic, mineral rich soils of sand, silt, and clay underlie these wetlands, while lily pads, cattails (see photo), reeds and bulrushes provide excellent habitat for waterfowl and other small mammals, such as Red-winged Blackbirds, Great Blue Herons, otters and muskrats. Bottomland Hardwood Forests are dominated by a variety of hardwood trees, including various oaks, red maple, ashes, sycamore, sweetgum and American elm. Trees commonly grow around the edge of the pool rather than inside the pool, where a variety of ferns, sedges, and other herbaceous plants can be found. Seeps usually occupy small areas on sloping hillsides leading down to a floodplain. Highly organic, mineral rich soils of sand, silt, … Groundwater and overland runoff from higher elevations provides slow surface water flow for headwater wetlands. 419 (956) Palustrine/lacustrine. The slow flow of water through a seep will saturate the soil most of the year.
