Where are marsh grasses found?
cordgrass, (genus Spartina), also called marsh grass, or salt grass, genus of 16 species of perennial grasses in the family Poaceae. Cordgrasses are found on marshes and tidal mud flats of North America, Europe, and Africa and often form dense colonies.
How does marsh grass grow?
In the zone that is regularly exposed at low water, salt marsh meadow grass gains a foothold and stabilizes the shifting substrate. The roots and stems slow and trap more sediment. As the annual growth dies back in the fall, the plant bodies become partially decomposed and form a bed of peat.
What is the purpose of marsh grass?
Coastal marsh plants provide significant protection from surges and devastating storms. For example, it's estimated that the damage caused by Hurricane Sandy was reduced by $625 million thanks to the damping of wave energy by extensive areas of marsh along the affected coasts.
How is marsh land formed?
Flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. Coastal wetlands also form when rivers deposit sediment as they reach the ocean. Plants then take root and hold the soil firm against the forces of tides and waves.
Who eats marsh grass?
As the grass dies it becomes a floating mass, called a wrack, and as it breaks down is eventually eaten by clams, mussels, crabs, and snails.
How deep is a marsh?
The water in freshwater marshes is usually one to six feet deep and is rich in minerals. Water flows into marshes from rain or from a water source like creeks, streams, or rivers. Low-growing plants like grasses and sedges are common in freshwater marshes. Bulrushes and cattails are often found at the edges of a marsh.
What is the benefits or uses of planting marsh grass?
Wetlands help to maintain water quality and marsh grasses slow run-off and allow sediments to fall out of suspension. Marsh plants remove excess nutrients and marsh mud can remove toxic heavy metals from the water. Wetlands help to control floods and reduce erosion during storms.
How do you get rid of marsh grass?
Use glyphosate as an effective post-emergence control of swamp grass, as recommended by the University of California Extension. The chemical is sold under different trade names. Spray herbicide on each weed to cover the plant well. You don't have to drench the weed to the point of runoff.
What is the difference between a swamp and a marsh?
The difference between the two is that swamps usually have deeper standing water and are wet for longer periods of the year, according to the National Parks Service. Marshes have rich, waterlogged soils that support plant life, according to National Geographic.
Can you build on marsh land?
Building on marsh lands can be more costly than you might assume, largely because you must first have the soil amended and strengthened. In some areas, this may just require bringing in a few extra truckloads of soil and compacting the ground to give the foundation a firm base.
Can you swim in a marsh?
It's easy to regard wetlands as mere wastelands, of little or no value. We don't build houses or factories in swamps, bogs or marshes, and we don't plant wheat or many other crops on land submerged in water. Wetlands are generally unsuitable for boating, swimming and most human activities.
What do marshes look like?
Marshes are dominated by herbaceous plants, such as grasses, reeds, and sedges. A marsh is a type of wetland, an area of land where water covers ground for long periods of time. Unlike swamps, which are dominated by trees, marshes are usually treeless and dominated by grasses and other herbaceous plants.
Is marsh grass a plant?
Marsh grasses and other herbaceous plants grow in the waterlogged but rich soil deposited by rivers. The plants roots bind to the muddy soil and slow the water flow, encouraging the spread of the marsh. These watery pastures are rich in biodiversity.
How do plants survive in marshes?
Aerenchyma are basically open spaces that allow oxygen to travel from the air, to the leaves and shoots, and down to the roots and rhizomes (underground root-like stems) that are underwater. This keeps the parts of the plant that are submerged happy!
What are three characteristics of a marsh?
Marshes are generally characterized by very slow-moving waters. They are usually associated with adjacent rivers, lakes, or oceans. Typically, a marsh features grasses, rushes, reeds, typhas, sedges, and other herbaceous plants (possibly with low-growing woody plants) in a context of shallow water.

Where are salt marshes found?
A salt marsh in Scotland. Saltwater marshes are found around the world in mid to high latitudes, wherever there are sections of protected coastline. They are located close enough to the shoreline that the motion of the tides affects them, and, sporadically, they are covered with water.
How do marshes improve water quality?
Marshes also improve water quality by acting as a sink to filter pollutants and sediment from the water that flows through them. Marshes partake in water purification by providing nutrient and pollution consumption. Marshes (and other wetlands) are able to absorb water during periods of heavy rainfall and slowly release it into waterways and therefore reduce the magnitude of flooding. Marshes also provide the services of tourism, recreation, education, and research.
What are marshes made of?
Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals.
Why are marshes important?
Marshes have extremely high levels of biological production, some of the highest in the world, and therefore are important in supporting fisheries. Marshes also improve water quality by acting as a sink to filter pollutants and sediment from the water that flows through them.

How to reduce arrowgrass loss?
How to Reduce Losses. Keep animals off areas where the growth of arrowgrass has been retarded by drought or frost or regrowth following harvest. The action of hydrocyanic acid is so rapid that it is usually too late to treat an affected animals after the signs of poisoning are recognized.
Is arrowgrass poisonous to hay?
Arrowgrass cut for hay may be toxic. Arrowgrass that is growing with adequate moisture does not cause poisoning. When growth is stressed or stunted from lack of moisture or frost, plants quickly become toxic. Regrowth foliage following harvest is also toxic.
Where is salt grass native to?
Saltgrass ( Distichlis spicata) is a widespread grass native to the Americas but naturalized on other continents. It is most common in areas of moist saline or alkaline soils, and is a major component of the vegetation in the lower parts of San Elijo Ecological Reserve.
How does saltgrass grow?
Like other salt marsh species, saltgrass can grow and reproduce at salinities that would kill most other plants. The surface of each leaf is equipped with many tiny salt glands that remove excess salt from plant tissues by excreting drops of highly concentrated saltwater onto the leaf surface where it will be washed off by high tide, rain or fog. Run a leaf between your fingers; the gritty feeling is caused by tiny flakes and crystals of dried salt. Look closely at a leaf in the sun; the crystals sparkle like tiny diamonds.
What is saltgrass used for?
In recent years, saltgrass has been used in the restoration of saline and alkaline wetlands where the strong root systems protect against erosion and buffer the adjacent land from pollutants carried by runoff water. 67 It is being grown in the Nature Collective nursery for use in revegetation projects in the Reserve.
What is a distichlis pistil?
The wind-born pollen is tiny. The pistil consists of a superior ovary and two plumose styles. There are two species of Distichlis native to the United States ( D. spicata and D. littoralis 129 ); both grow in the Reserve.
How tall is saltgrass?
Saltgrass is generally low growing, less than 20 inches (50 cm) in height. Leaves (blades) are produced alternately from the joints (nodes) of upright stems; leaves of each side lie in a single plane, giving the plant a pressed look.
What do salt glands do to the leaves of a grass?
Salt glands on both surfaces excrete drops of saline water that initially resemble heavy dew and evaporate to salt flakes and crystals that give the leaves a gritty feel and sparkly appearance. Saltgrass flowers ( florets) are not common.
What are the stems of grass?
Grasses have unique terminology. They are recognized by their cylindrical stems (culms), which are generally hollow or pith-filled with solid joints (nodes). Leaves (blades) are flat, attached to alternate nodes; leaf bases wrap the stem forming the leaf sheaths.
Habitat
Life cycle
- Herbaceous plants have no woody stem above ground, and they grow and die back on a regular cycle. Herbaceous plants can be annuals (which grow anew every year), biennials (which take two years to complete their life cycle), or perennials (which take more than two years to complete their life cycle.)
Types
- There are three types of marshes: tidal salt marshes, tidal freshwater marshes, and inland freshwater marshes. Marshes are also common in deltas, where rivers empty into a larger body of water. Although all are waterlogged and dominated by herbaceous plants, they each have unique ecosystems.
Functions
- Both saltwater and freshwater tidal marshes serve many important functions: They buffer stormy seas, slow shoreline erosion, offer shelter and nesting sites for migratory water birds, and absorb excess nutrients that would lower oxygen levels in the sea and harm wildlife.
Purpose
- The marshes along the Gulf Coast in the U.S., for instance, help protect communities in the states of Louisiana, Alabama, Texas, and Florida from hurricanes. Marshes cannot stop hurricanes, of course, but the wetland slows the progress of the storm and absorbs much of the surging water from the Gulf of Mexico.
Benefits
- Finally, draining marshes increases the direct runoff flowing to the ocean. Marshes are able to absorb toxic chemicals that leach into waterways from pesticides used in agriculture, as well as industrial pollutants. Without the marshy sponge, runoff flows directly to the ocean, often creating coastal \"dead zones\" where there is little life below the water's surface. The frequent dead zon…
Culture
- Plants such as sawgrass and pickleweed can tolerate fluctuating tidal waters, which are too salty for most trees and bushes.
Wildlife
- Like all marshes, tidal salt marshes are home to a wide variety of bird species. Small birds such as terns on fish, insects, and crustacean species found in the marsh. Ducks and cormorants are aquatic birds that rely on the grassy marsh for nesting sites as well as food such as fish, shrimp, and crabs. Even large raptors such as osprey are supported by tidal salt marshes.
Effects
- Tidal freshwater marshes lie farther inland than salt marshes, but are close enough to the coast to be affected by tidal fluctuations. Just like in salt marshes, the water level rises and falls twice every day, along with the tides.
Ecology
- Herbaceous plants called sedges dominate the tidal freshwater marsh ecosystem. Sedges include water chestnut and papyrus. Marshy papyrus is one of the most important plants in the development of civilization: Papyrus growing in the marshy delta of the Nile River was dried, treated, and used as an early form of paper by ancient Egyptians. The abundant insects of fresh…
Reproduction
- Freshwater tidal marshes also provide spawning grounds for fish such as shad and herring. These fish are anadromous. Anadromous fish hatch in freshwater, but migrate and live most of their lives in the ocean. They return to freshwater rivers, streams, and marshes to spawn.
Behavior
- Other freshwater marshes are much more aquatic. The Everglades, the largest freshwater marsh in the United States, are drowned in a shallow layer of water all year. In fact, the Everglades actually form a wide, slow-moving river draining out of Lake Okeechobee.
Flora and fauna
- The Everglades are rich in biodiversity. This so-called \"River of Grass\" supports such plants as sawgrass, cypress, and mangrove forests. They are home to animals such as ducks, geese, raccoons, turtles, and frogs. Predators such as alligators and panthers are also indigenous to the Everglades.
Environment
- The marshes of Doana National Park, in Andalusia, Spain, have been greatly affected by human activity along the Guadalquivir and Guadiamar Rivers. The rivers waters have been drained and diverted to expand agricultural production, salt extraction, and tourist facilities. With less water feeding into their ecosystems, the marshes at Doana have been reduced from 150,000 hectares …
Conservation
- As a result, plant and animal species have diminished. The World Wildlife Fund and the Spanish government are now working to increase the water flow that enters the ecosystem. Their approach, like most marsh restoration programs, requires the cooperation of government officials, environmental regulators, agricultural producers, and the public.
Overview
Basic information
Values and ecosystem services
- Sawgrass (Cladium jamaicense) is the predominant marsh grass in the Everglades. Sawgrass is a course, perennial sedge with an extensive network of rhizomes. The flat leaves have saw-toothed edges and reach up to 10 feet long. This type of marsh grass is typically found growing in shallow, freshwater marshes. It thrives in seasonally flooded areas a...
Types of marshes
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 swa…
Restoration
Marshes provide a habitat for many species of plants, animals, and insects that have adapted to living in flooded conditions. The plants must be able to survive in wet mud with low oxygen levels. Many of these plants, therefore, have aerenchyma, channels within the stem that allow air to move from the leaves into the rooting zone. Marsh plants also tend to have rhizomes for undergroun…
