What is a marsh grass?
Marsh grasses are coarse plants with soft stems that thrive best in wet conditions. They may exist in fresh or saltwater wetland areas. Marsh grasses are commonly found in the eastern, western and southern areas of the United States.
What are the characteristics of a marsh?
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. Herbaceous plants have no woody stem above ground, and they grow and die back on a regular cycle.
Why don't marsh grasses grow in salt marshes?
This type of marsh grass is limited to higher salt marches because it cannot tolerate the lower oxygen levels of the lower marshes. Saltmeadow cordgrass typically produces flower spikes from July to October.
What is the difference between marsh grass and spike grass?
Marsh grasses, also called cord grasses, are soft-stem, coarse plants that have adapted to thrive in soil that is continuously saturated. Common cattail is commonly found growing on the edges of freshwater marshes where the water is shallower. Spike grass (Distichlis spicata) is a perennial marsh grass belonging to the Poaceae family.

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.
What is the grass called in marshes?
cordgrasscordgrass, (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.
Is marsh good for plants?
Marshes have rich, waterlogged soils that support plant life, according to National Geographic. The plants that grow in marshes bind to the muddy soil, which slows the flow of the water.
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.
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 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 plants live in high marsh?
Species such as fire bush (Hamelia patens), seaside goldenrod (Solidago sempervirens), beauty berry (Callicarpa americana), and yaupon holly (llex vomitori) provide beautiful blooms and can be kept as shrubs. Indian blanket flower (Gaillardia pulchella), beach sunflower (Helianthus debilis), railroad vine (Ipomoea pes-caprae), and sunshine mimosa (Mimosa strigillosa) provide impressive ground cover and colorful flowers during the spring and summer months. These plants provide shoreline stabilization due to their large root systems that anchor and hold onto loose soils.
What is cord grass?
Smooth cordgrass (Spartina Alterniflora) is a hardy, native, halophyte tidal grass often used in shoreline restoration work and, in combination with oyster reefs, can significantly reduce wave impacts on a shoreline. It has a tight root system that holds it in place very well and efficiently traps sediment, reducing shoreline erosion. Its dense stalks serve as habitat and protection for many intertidal creatures such as juvenile sportfish, various arthropods, and many invertebrates. Naturally, cordgrass does not take root very easily, but propagates quickly once it is established.

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.
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…
Formation
- Tidal salt marshes form a grassy fringe near river mouths, bays, and along coastlines protected from the open ocean. Ocean tides fill the marsh with salty water and cause the water level to rise and fall twice a day. The marsh is deeper at high tide and shallower at low tide.
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 hectare…
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.
