Coniferous swamps are forested wetlands in which the dominant trees are lowland conifers such as northern white cedar (Thuja occidentalis). The soil in these swamp areas is typically saturated for most of the growing season and is occasionally inundated by seasonal storms or by winter snow melt.
The substrate is usually organic in nature and may contain peat in varying amounts or be composed entirely of muck. The swamp substrate is typically nutrient-rich and neutral to alkaline but can be acidic and nutrient-poor.
Coniferous swamps vary in composition, with different species of conifer dominating, and varying amounts of deciduous hardwoods growing within the swamp. A wide diversity of plants is represented within the swamps, with certain species dominating in a variety of microhabitats dependent on factors such as available sunlight (as in cases of trees downed by wind or disease), soil Ph, standing groundwater, and differences of elevation within the swamp such as tussocks and nurse logs.
The different types of coniferous swamps are referred to according to their dominant trees. Rich conifer swamp is dominated by Northern white-cedar and typically occurs south of the climatic tension zone throughout the Midwest and northeastern United States and adjacent areas in Canada. North of the climatic tension zone, tamarack (Larix laricina) is the dominant species of conifer in minerotrophic wetlands classified as rich tamarack swamp. A roughly equal mix of hardwood trees and conifers is known as a hardwood-conifer swamp.
A variety of both evergreen and deciduous trees may be present in the rich conifer swamp in addition to the dominant species.
A variety of grasses and sedges may be present including multiple varieties of carex.
A Directory of Important Wetlands in Australia (DIWA) is a list of wetlands of national importance to Australia. Intended to augment the list of wetlands of international importance under the Ramsar Convention, it was formerly published in report form, but is now essentially an online publication. Wetlands that appear in the Directory are commonly referred to as "DIWA wetlands" or "Directory wetlands".Bear Head Lake State Park
Bear Head Lake State Park is a state park of Minnesota, United States, providing ready access to outdoor recreation in the Boundary Waters region. It boasts scenery similar to the nearby Boundary Waters Canoe Area Wilderness, with the added conveniences of road access, modern facilities, and motorboating. The most popular visitor activities are boating, fishing, swimming, and hiking. The park entirely surrounds 670-acre (270 ha) Bear Head Lake and three other fishing lakes. It was established in 1961 in Saint Louis County near Ely, Minnesota. The park also contains the woodlands surrounding the lakes, which gives an entire total of about 5,540 acres. The park also shares a large border with Bear Island State Forest.
In September 2010, Bear Head Lake State Park was voted "America's Favorite Park" in a major online poll. The little-known park, not even among Minnesota's most popular, won in a surprise landslide, capturing 28% of the more than 5.7 million votes. The strong showing was credited to the online fan community of mother and cub black bears, featured on a popular webcam, whose territory included the park.Beltrami Island State Forest
The Beltrami Island State Forest is a state forest located in Lake of the Woods, Roseau, and Beltrami counties, Minnesota. Named after Italian explorer Giacomo Beltrami, it is the second-largest state forest in the Minnesota system after Pine Island State Forest. The largest wildlife management area in the state at 321,149 acres (129,964 ha), the Red Lake Wildlife Management Area, is located within the forest. The majority of the forest is managed by the Minnesota Department of Natural Resources, although a significant portion are tribal lands belonging to the neighboring Red Lake Band of Ojibwe.
French explorers came to the area around 1730 in their search for a route to the Pacific Ocean, retaining control of the area via the fur trade until after 1760, when the British Hudson's Bay Company gained control of the area. The Treaty of 1818 gave the Americans technical control over the area, although the Ojibwe retained control over the land until ceding all their holdings in the Red River Valley as a result of the Treaty of Old Crossing in 1863.
The majority of land in the forest is coniferous swamp dominated by species such as black spruce, tamarack, and northern white cedar, although red pine, jack pine, and aspen exist in upland areas. Much of the pine that characterizes the upland acreage were planted by the federal Civilian Conservation Corps in the 1930s, based out of Norris Camp now located in the Red Lake WMA portion of the forest. Within the perimeters of the forest are the headwaters of the Roseau River, Warroad River, Rapid River, and Moose River. All rivers ultimately drain northward into Hudson Bay due to the forests location north of the Laurentian Divide.
Outdoor recreation activities include hiking and mountain biking on provided trails, as well as backcountry camping. Trails include 25 miles (40 km) of hiking, 27 miles (43 km) of horseback riding, 238 miles (383 km) available for Class I and II all-terrain vehicle use as well as dirt biking, and 138 miles (222 km) for snowmobiling. Nearby Zippel Bay State Park and adjacent Hayes Lake State Park have facilities suitable for camping.Flooded grasslands and savannas
Flooded grasslands and savannas is a terrestrial habitat type of the WWF biogeographical system, consisting of large expanses or complexes of flooded grasslands. These areas support numerous plants and animals adapted to the unique hydrologic regimes and soil conditions. Large congregations of migratory and resident waterbirds may be found in these regions. However, the relative importance of these habitat types for these birds as well as more vagile taxa typically varies as the availability of water and productivity annually and seasonally shifts among complexes of smaller and larger wetlands throughout a region.This habitat type is found on four of the continents on Earth. Some globally outstanding flooded savannas and grasslands occur in the Everglades, Pantanal, Sahelian flooded savannas, Zambezian flooded savannas, and the Sudd. The Everglades are the world’s largest rain-fed flooded grassland on a limestone substrate, and feature some 11,000 species of seed-bearing plants, 25 varieties of orchids, 300 bird species, and 150 fish species. The Pantanal, one of the largest continental wetlands on Earth, supports over 260 species of fish, 700 birds, 90 mammals, 160 reptiles, 45 amphibians, 1,000 butterflies, and 1,600 species of plants. The flooded savannas and grasslands are generally the largest complexes in each region.Freshwater swamp forest
Freshwater swamp forests, or flooded forests, are forests which are inundated with freshwater, either permanently or seasonally. They normally occur along the lower reaches of rivers and around freshwater lakes. Freshwater swamp forests are found in a range of climate zones, from boreal through temperate and subtropical to tropical.
In the Amazon Basin of Brazil, a seasonally flooded forest is known as a várzea, a use that now is becoming more widespread for this type of forest in the Amazon (though generally spelled varzea when used in English). Igapó, another word used in Brazil for flooded Amazonian forests, is also sometimes used in English. Specifically, varzea refers to whitewater-inundated forest, and igapó to blackwater-inundated forest.
Peat swamp forests are swamp forests where waterlogged soils prevent woody debris from fully decomposing, which over time creates a thick layer of acidic peat.Grandma Lake Wetlands State Natural Area
Grandma Lake Wetlands State Natural Area is a Wisconsin Department of Natural Resources-designated State Natural Area featuring the undeveloped, pristine 44-acre Grandma Lake, which lies in a depression formed during the last glacial period. The lake is ringed by a large, open sphagnum bog mat. The bog mat is surrounded by a coniferous swamp of tamarack (Larix laricina) and black spruce (Picea mariana). The bog mat supports a plant community that is considered diverse and unusual, with several rare species present, including: bog arrow-grass (Triglochin maritima), dragon's mouth orchid (Arethusa bulbosa), livid sedge (Carex livida), small-headed bog sedge (Carex tenuiflora), as well as one of only a few known populations of bog rush (Juncus stygius) in the State of Wisconsin. In 1991, the US Forest Service designated the site as a Research Natural Area. Also, the site is listed as one of Wisconsin's Wetland Gems, by the Wisconsin Wetlands Association.Murray Bridge Training Area
The Murray Bridge Training Area (also called Murray Bridge Army Training Area) is an Australian Army training area located in South Australia in the locality of Burdett about 7 kilometres (4.3 miles) east of the city of Murray Bridge and about 70 kilometres (43 miles) east of the centre of the city of Adelaide. The training area was established prior to 1970. As of 2011, the training area contained shooting ranges for use with small arms for distances up to 800 metres (2,600 feet), space for the training of subunits from Australian Army units located within South Australia and support facilities such as a “vehicle maintenance compound.” An area of about 71 hectares (180 acres) within the training area was developed as an artificial wetland in 1992 for the purpose of treating effluent that would otherwise have been discharged into the Murray River. This wetland has been listed as a wetland of national importance since at least 1995.National Wetlands Inventory
The National Wetlands Inventory (NWI) was established by the United States Fish and Wildlife Service (FWS) to conduct a nationwide inventory of U.S. wetlands to provide biologists and others with information on the distribution and type of wetlands to aid in conservation efforts. To do this, the NWI developed a wetland classification system (Cowardin et al. 1979) that is now the official FWS wetland classification system and the Federal standard for wetland classification (adopted by the Federal Geographic Data Committee on July 29, 1996: 61 Federal Register 39465). The NWI also developed techniques for mapping and recording the inventory findings. The NWI relies on trained image analysts to identify and classify wetlands and deepwater habitats from aerial imagery. NWI started mapping wetlands at a small scale (1:250,000 map which covers an area the size of 128-1:24,000 USGS topographic maps or approximately 7,400 square miles). Eventually, large-scale (1:24K scale) maps became the standard product delivered by NWI. As computerized mapping and geospatial technology evolved, NWI discontinued production of paper maps in favor of distributing data via online "mapping tools" where information can be viewed and downloaded. Today, FWS serves its data via an on-line data discovery "Wetlands Mapper". GIS users can access wetlands data through an online wetland mapping service or download data for various applications (maps, data analyses, and reports). The techniques used by NWI have recently been adopted by the Federal Geographic Data Committee as the federal wetland mapping standard (FGDC Wetlands Subcommittee 2009). This standard applies to all federal grants involving wetland mapping to insure the data can be added to the Wetlands Layer of the National Spatial Data Infrastructure. NWI also produces national wetlands status and trends reports required by the United States Congress.Natural areas in King, Ontario
There are numerous natural areas in King, a township in Ontario, Canada. These areas are zones officially designated by the Government of Ontario that are within the township and exhibit provincially or regionally significant features representative of the region. The list of zones is defined and maintained by the provincial Ministry of Natural Resources Natural Heritage Information Centre.
Site and region surveys have been conducted by various means. Some areas were identified and classified through the International Biological Program between 1964 and 1974. Others may have had a superficial initial classification, and subsequently been re-classified upon closer scrutiny. Fifty areas have been classified in the township.Ramsar Convention
The Ramsar Convention on Wetlands of International Importance especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of wetlands. It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the Convention was signed in 1971.
Every three years, representatives of the Contracting Parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the Convention which adopts decisions (Resolutions and Recommendations) to administer the work of the Convention and improve the way in which the Parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018.Sleaford Mere
Sleaford Mere (alternative name: Kuyabidni) is a permanent saline lake, located on the Jussieu Peninsula on the south eastern tip of Eyre Peninsula in South Australia about 15 kilometres (9.3 miles) south west of Port Lincoln. The lake was discovered and named by the British explorer, Matthew Flinders, on 26 February 1802. Since 1969, the lake has been part of the Sleaford Mere Conservation Park and since 2005, it has been listed as a nationally important wetland. The lake and its environs are notable as a venue for recreational pursuits such as canoeing.Swamp
A swamp is a wetland that is forested. Many swamps occur along large rivers where they are critically dependent upon natural water level fluctuations. Other swamps occur on the shores of large lakes. Some swamps have hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates periodic inundation or soil saturation. The two main types of swamp are "true" or swamp forests and "transitional" or shrub swamps. In the boreal regions of Canada, the word swamp is colloquially used for what is more correctly termed a bog, fen, or muskeg. The water of a swamp may be fresh water, brackish water or seawater. Some of the world's largest swamps are found along major rivers such as the Amazon, the Mississippi, and the Congo.Watervalley Wetlands
The Watervalley Wetlands is a nationally important wetland system located in the Australian state of South Australia which consists of a series of contiguous wetlands, lying on 56.6 square kilometres (21.9 sq mi) of private land between the Coorong National Park and Gum Lagoon Conservation Park, in the state's south-east.Wetland
A wetland is a distinct ecosystem that is inundated by water, either permanently or seasonally, where oxygen-free processes prevail. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil. Wetlands play a number of functions, including water purification, water storage, processing of carbon and other nutrients, stabilization of shorelines, and support of plants and animals. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life. Whether any individual wetland performs these functions, and the degree to which it performs them, depends on characteristics of that wetland and the lands and waters near it. Methods for rapidly assessing these functions, wetland ecological health, and general wetland condition have been developed in many regions and have contributed to wetland conservation partly by raising public awareness of the functions and the ecosystem services some wetlands provide.Wetlands occur naturally on every continent. 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. Many peatlands are wetlands. The water in wetlands is either freshwater, brackish, or saltwater.
Wetlands can be tidal (inundated by tides) or non-tidal. The largest wetlands include the Amazon River basin, the West Siberian Plain, the Pantanal in South America, and the Sundarbans in the Ganges-Brahmaputra delta.The UN Millennium Ecosystem Assessment determined that environmental degradation is more prominent within wetland systems than any other ecosystem on Earth.Constructed wetlands are used to treat municipal and industrial wastewater as well as stormwater runoff. They may also play a role in water-sensitive urban design.Wye Marsh
The Wye Marsh is a wetland area on the south shores of Georgian Bay in Ontario, Canada. The Wye Marsh National Wildlife Area was established on the location in 1978. It is designated a Provincially Significant Wetland by the Ontario Ministry of Natural Resources.
