A marsh is a wetland that is dominated by herbaceous rather than woody plant species. Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and then sometimes called carrs. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat.
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection.
Callaloo is a popular Caribbean vegetable dish. There are many variants across the Caribbean, depending on the availability of local vegetables. The main ingredient is an indigenous leaf vegetable, traditionally either amaranth, taro leaves or Xanthosoma leaves.
Amaranthus blitum, commonly called purple amaranth or Guernsey pigweed, is an annual plant species in the economically important plant family Amaranthaceae.
A tumbleweed is a structural part of the above-ground anatomy of a number of species of plants. It is a diaspore that once it is mature and dry, detaches from its root or stem and rolls due to the force of the wind. In most such species, the tumbleweed is in effect the entire plant apart from the root system, but in other plants, a hollow fruit or inflorescence might detach instead. Xerophyte tumbleweed species occur most commonly in steppe and arid ecosystems, where frequent wind and the open environment permit rolling without prohibitive obstruction.
Don Edwards San Francisco Bay National Wildlife Refuge (DESFBNWR) is a United States National Wildlife Refuge located in the southern part of San Francisco Bay, California. The Refuge headquarters and visitor center is located in the Baylands district of Fremont, next to Coyote Hills Regional Park, in Alameda County. The visitor center is on Marshlands Rd, off Thornton Ave.
Amaranthus caudatus is a species of annual flowering plant. It goes by common names such as love-lies-bleeding, pendant amaranth, tassel flower, velvet flower, foxtail amaranth, and quilete.
Species belonging to the genus Amaranthus have been cultivated for their grains for 8,000 years. Amaranth plants are classified as pseudocereals that are grown for their edible starchy seeds, but they are not in the same botanical family as true cereals, such as wheat and rice. Amaranth species that are still used as a grain are Amaranthus caudatus L., Amaranthus cruentus L., and Amaranthus hypochondriacus L. The yield of grain amaranth is comparable to rice or maize.
Amaranthus brownii was an annual herb in the family Amaranthaceae. The plant was found only on the small island of Nihoa in the Northwestern Hawaiian Islands, growing on rocky outcrops at altitudes of 120–215 m (394–705 ft). It was one of nine species of Amaranthus in the Hawaiian Islands, as well as the only endemic Hawaiian species of the genus. It is now considered extinct.
Amaranthus floridanus, the Florida amaranth, is a flowering plant endemic to Florida.
The Blackwater River is a 3.1-mile-long (5.0 km) tidal inlet in northeastern Massachusetts and southeastern New Hampshire in the United States.
The Browns River is a 2.9-mile-long (4.7 km) river, primarily tidal, in southeastern New Hampshire in the United States. It is part of the largest salt marsh in New Hampshire, covering over 3,800 acres (15 km2).
Amaranthus tuberculatus, commonly known as roughfruit amaranth, rough-fruited water-hemp, tall waterhemp, or common waterhemp, is a species of flowering plant. It is a summer annual broadleaf with a germination period that lasts several months. Tall waterhemp has been reported as a weed in 40 of 50 U.S. states.
Water-hemp or waterhemp is a common name for several plants and may refer:
San Pablo Bay National Wildlife Refuge is a 13,190-acre (53.4 km2) National Wildlife Refuge in California established in 1970. It extends along the northern shore of San Pablo Bay, from the mouth of the Petaluma River, to Tolay Creek, Sonoma Creek, and ending at Mare Island.
Brackish marshes develop by salt marshes where a significant freshwater influx dilutes the seawater to brackish levels of salinity. This commonly happens upstream from salt marshes by estuaries of coastal rivers or near the mouths of coastal rivers with heavy freshwater discharges in the conditions of low tidal ranges.
Tijuana Slough National Wildlife Refuge is located in the most southwestern corner of the contiguous United States. As a National Wildlife Refuge, it is administered by the U.S. Fish and Wildlife Service. It was established in 1980.
San Diego Bay National Wildlife Refuge is an urban refuge located on San Diego Bay in San Diego County, California. It is part of the San Diego National Wildlife Refuge Complex. It was dedicated in June 1999.
Spartina patens, the saltmeadow cordgrass, also known as salt hay, is a species of cordgrass native to the Atlantic coast of the Americas, from Newfoundland south along the eastern United States to the Caribbean and northeast Mexico. It has been reclassified as Sporobolus pumilus after a taxonomic revision in 2014, but Spartina patens is still in common usage. It can be found in marshlands in other areas of the world as an introduced species and often a harmful noxious weed or invasive species.
