A salt marsh, saltmarsh or salting, 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.
Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers. A global analysis published in 2019 suggested that tidal flat ecosystems are as extensive globally as mangroves, covering at least 127,921 km2 (49,391 sq mi) of the Earth's surface. They are found in sheltered areas such as bays, bayous, lagoons, and estuaries; they are also seen in freshwater lakes and salty lakes alike, wherein many rivers and creeks end. Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and aquatic animal detritus. Most of the sediment within a mudflat is within the intertidal zone, and thus the flat is submerged and exposed approximately twice daily.
A tidal marsh is a marsh found along rivers, coasts and estuaries which floods and drains by the tidal movement of the adjacent estuary, sea or ocean. Tidal marshes experience many overlapping persistent cycles, including diurnal and semi-diurnal tides, day-night temperature fluctuations, spring-neap tides, seasonal vegetation growth and decay, upland runoff, decadal climate variations, and centennial to millennial trends in sea level and climate.
The Goleta Slough is an area of estuary, tidal creeks, tidal marsh, and wetlands near Goleta, California, United States. It primarily consists of the filled and unfilled remnants of the historic inner Goleta Bay about 8 miles (13 km) west of Santa Barbara. The slough empties into the Pacific Ocean through an intermittently closed mouth at Goleta Beach County Park just east of the UCSB campus and Isla Vista. The slough drains the Goleta Valley and watershed, and receives the water of all of the major creeks in the Goleta area including the southern face of the Santa Ynez Mountains.
The University of California Natural Reserve System (UCNRS) is a system of protected areas throughout California. The reserves support UC's mission of teaching, research, and public service. Unlike national and state parks, they are not available for recreational uses, because they were specifically created to enable UC scientists to conduct research free from such distractions.
Mission Bay is an artificial, saltwater bay located south of the Pacific Beach community of San Diego, California, created from approximately 2,000 acres (810 ha) of historical wetland, marsh, and saltwater bay habitat. The bay is part of the recreational Mission Bay Park, the largest man-made aquatic park in the United States, consisting of 4,235 acres (17.14 km2), approximately 46% land and 54% water. The combined area makes Mission Bay Park the ninth largest municipally-owned park in the United States.
California's coastal salt marsh is a wetland plant community that occurs sporadically along the Pacific Coast from Humboldt Bay to San Diego. This salt marsh type is found in bays, harbors, inlets, and other protected areas subject to tidal flooding.
Great Bay is located in southern New Jersey's Atlantic Coastal Plain in Ocean and Atlantic Counties, about ten miles (16 km) north of Atlantic City and is about 5.5 miles northwest of Brigantine, and 5.5 miles southwest of Beach Haven. The Mullica River flows into the bay, and together they form the Mullica River - Great Bay estuary habitat. The bay is connected to the Atlantic Ocean via the Little Egg Inlet. Great Bay is considered one of the least-disturbed marine wetlands habitats in the northeastern United States.
Seal Slough, also known as Marina Lagoon, is a narrow winding tidal channel through a tidal marsh in San Mateo and Foster City, California. This slough has been the object of a wetland restoration project in recent years to enhance habitat value. Dredging has been carried out in Seal Slough since at least 1954. When the original sewage treatment plant for the city of San Mateo was constructed in 1935, its discharge was directed to Seal Slough.
The Seal Beach National Wildlife Refuge is a wildlife refuge encompassing 965 acres (3.91 km2) located in the California coastal community of Seal Beach. Although it is located in Orange County it is included as part of the San Diego National Wildlife Refuge Complex. It was established in 1972.
The Steart Peninsula is a peninsula in Somerset, England. At its outermost tip is Fenning Island, at the tip of which is Stert Point which is the eastern end of the West Somerset Coast Path. North of Stert Point lies Stert Island, which was joined to the peninsula until about 1798. The peninsula consists largely of low-lying flat farmland, and projects northwards on the west side of Stockland Reach, the lower stretches of the estuary of the River Parrett.
The Rachel Carson National Wildlife Refuge is a 9,125-acre (37 km2) National Wildlife Refuge made up of several parcels of land along 50 miles (80 km) of Maine's southern coast. Created in 1966, it is named for environmentalist and author Rachel Carson, whose book Silent Spring raised public awareness of the effects of DDT on migratory songbirds, and of other environmental issues.
Elkhorn Slough is a 7-mile-long (11 km) tidal slough and estuary on Monterey Bay in Monterey County, California. It is California's second largest estuary and the United States' first estuarine sanctuary. The community of Moss Landing and the Moss Landing Power Plant are located at the mouth of the slough on the bay.
Mary's Point is a 12 square kilometres (4.6 sq mi) wetland in Albert County, New Brunswick, Canada. It is at the head of the Bay of Fundy, just outside the small community of Harvey and approximately 40 km (25 mi) south of Moncton. Designated a Ramsar wetland of international importance on May 24, 1982, it is also part of the Fundy biosphere reserve established in 2007, which also contains the Shepody Bay wetland. It was also the first Canadian site in the Western Hemisphere Shorebird Reserve, as part of the Bay of Fundy Hemisphere Shorebird Reserve. It is within the Shepody Bay National Wildlife Area, which is administered by the Canadian Wildlife Service.
Bahia Lomas is a bay in the eastern mouth of the Strait of Magellan in Southern Chile, on the north coast of the Isla Grande de Tierra del Fuego. The area is a large tidal plain, with a tidal variation up to 7 km. The wetlands of the bay are important sites for the red knot, the Hudsonian godwit and other shorebirds. The wetlands are a Ramsar site of international importance and an Important Bird Area.
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.
The San Diego National Wildlife Refuge Complex is a series of wildlife refuges established by the United States National Wildlife Service beginning in 1972. The complex incorporates five refuges in San Diego County and Orange County in California.
The Las Piñas–Parañaque Critical Habitat and Ecotourism Area (LPPCHEA), also known as the Las Piñas–Parañaque Wetland Park, is a protected area at the coasts of the cities of Las Piñas and Parañaque in Metro Manila, Philippines. The entire wetland is a declared Ramsar site under the Ramsar Convention of UNESCO.
Younger Lagoon Reserve is a 72-acre (28-hectare) University of California Natural Reserve System reserve on the northern shore of Monterey Bay in Santa Cruz County, California. The site is owned by the University of California and managed for teaching and research. It is adjacent to Long Marine Laboratory.
The San Francisco Bay Salt Ponds are a roughly 16,500-acre (6,700 ha) part of the San Francisco Bay that have been used as salt evaporation ponds since the California Gold Rush era. Most of the ponds were once wetlands in the cities of Redwood City, Newark, and Hayward, and other parts of the bay.
