Carex paleacea commonly known as chaffy sedge is one of the 579 species of Carex . The Wetland Indicator Status for the species is classified as "obligate wetland" (OBL), occurring 99% of the time in a typical salt marsh environment when conditions are favorable. [1]
Mer Bleue Bog is a 33.43 km2 (12.91 sq mi) protected area east of Ottawa in Eastern Ontario, Canada. Its main feature is a sphagnum bog that is situated in an ancient channel of the Ottawa River and is a remarkable boreal-like ecosystem normally not found this far south. Stunted black spruce, tamarack, bog rosemary, blueberry, and cottongrass are some of the unusual species that have adapted to the acidic waters of the bog.
Reed beds are natural habitats found in floodplains, waterlogged depressions, and estuaries. Reed beds are part of a succession from young reeds colonising open water or wet ground through a gradation of increasingly dry ground. As reed beds age, they build up a considerable litter layer that eventually rises above the water level and that ultimately provides opportunities for scrub or woodland invasion. Artificial reed beds are used to remove pollutants from grey water.
Carex is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges. Other members of the family Cyperaceae are also called sedges, however those of genus Carex may be called true sedges, and it is the most species-rich genus in the family. The study of Carex is known as caricology.
Carex lasiocarpa is a broadly distributed species of wetland sedge sometimes known as woollyfruit sedge or slender sedge. It is considered a species of Least Concern by the IUCN Red List due to its extensive range with many stable populations.
Carex canescens L. is a perennial species of plants in the family Cyperaceae growing in damp forests and wetlands. It is widespread across much of Europe, Asia, Australia, New Guinea, North America, and southern South America.
Carex nigra (L.) Reichard is a perennial species of plants in the family Cyperaceae native to wetlands of Europe, western Asia, northwestern Africa, and eastern North America. Common names include common sedge, black sedge or smooth black sedge. The eastern limit of its range reaches central Siberia, Turkey and probably the Caucasus.
Carex athrostachya is a species of sedge known by the common name slenderbeak sedge. It is native to western North America, including Alaska to central Canada, the western contiguous United States, and just into Baja California.
Carex comosa is a species of sedge known as longhair sedge and bristly sedge. It is native to North America, where it grows in western and eastern regions of Canada and the United States, and parts of Mexico. It grows in wet places, including meadows and many types of wetlands. Tolerates deeper water than most common species and is good for retention basins. This sedge produces clumps of triangular stems up to 100 or 120 centimeters tall from short rhizomes. The inflorescence is up to 35 centimeters long and has a long bract which is longer than the spikes. It is a cluster of several cylindrical spikes. The scales over the fruits taper into long, thin awns.
Carex diandra is a species of sedge known by the common names lesser tussock-sedge and lesser panicled sedge.
Carex nebrascensis is a species of sedge known as Nebraska sedge.
Carex scoparia is a species of sedge known by the common names broom sedge and pointed broom sedge. It should not be confused with the unrelated grass species known as "broom sedge," Andropogon virginicus.
Carex utriculata is a species of sedge known as Northwest Territory sedge and common yellow lake sedge.
Salt pannes and pools are water retaining depressions located within salt and brackish marshes. Pools tend to retain water during the summer months between high tides, whereas pannes generally do not. Salt pannes generally start when a mat of organic debris is deposited upon existing vegetation, killing it. This creates a slight depression in the surrounding vegetation which retains water for varying periods of time. Upon successive cycles of inundation and evaporation the panne develops an increased salinity greater than that of the larger body of water. This increased salinity dictates the type of flora and fauna able to grow within the panne. Salt pools are also secondary formations, though the exact mechanism(s) of formation are not well understood; some have predicted they will increase in size and abundance in the future due to rising sea levels.
Pike Whin Bog is a Site of Special Scientific Interest in the Easington district of east County Durham, England. It is situated just east of Hurworth Burn Reservoir, about 8 km west of Hartlepool.
Carex hirta, the hairy sedge or hammer sedge, is a species of sedge native across Europe. It has characteristic hairy leaves and inflorescences, and is the type species of the genus Carex.
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 and black spruce. The bog mat supports a plant community that is considered diverse and unusual, with several rare species present, including: bog arrow-grass, dragon's mouth orchid, livid sedge, small-headed bog sedge, as well as one of only a few known populations of bog rush 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.
Carex lacustris, known as lake sedge, is a tufted grass-like perennial of the sedge family (Cyperaceae), native to southern Canada and the northern United States. C. lacustris us an herbaceous surface-piercing plant that grows in water up to 50 cm (1.6 ft) deep, and grows 50–150 cm (1.6–4.9 ft) tall. It grows well in marshes and swampy woods of the boreal forest, along river and lake shores, in ditches, marshes, swamps, and other wetland habitat. It grows on muck, sedge peat, wet sand or silt, in filtered or full sunlight.
Carex cristatella is a species of sedge native to eastern North America. It is an introduced species in Europe. Carex cristatella is a common species in wetlands such as swamps, marshes, shorelines, and wet prairies.
Carex sect. Phacocystis is a section of the genus Carex, containing between 70 and 90 species worldwide. With 31 species in the North American flora, sedges in Carex sect. Phacocystis commonly occur in wetlands such as shorelines, marshes, and tundra.
Carex × subpaleacea is a species of sedge and is native to Finland, Labrador, Norway, Ontario, and Quebec.
