What does cord grass do?

Smooth cordgrass is also known as saltmarsh cordgrass. It is the dominant grass in the Bay's salt marshes. This grass can be used to control shoreline erosion. It also provides important habitat for marsh periwinkles, ribbed mussels and fiddler crabs.

How does cord grass get nutrients?

Cordgrass obtains its nutrients by photosynthesizing. California cordgrass reproduces sexually and asexually. There are male and female flowers. It spreads primarily by vegetative propagation year-round by forming new clones from its extensive underground rhizome system.

What do smooth cordgrass eat?

It takes about a year for the grass to be broken down into pieces of detritus small enough to be eaten by other animals. Clams, oysters, mussels, snails, crabs, and many other animals feed on this detritus. Spartina grass also provides habitat for many animals.

Why is cord grass Spartina important?

Smooth cordgrass is an important component of Gulf Coast salt marshes which stabilize shorelines against erosion and filter heavy metals and toxic materials from the water column [13].

What species is cordgrass?

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.

Is cord grass a foundation species?

In the region, the dominant foundation species is smooth cordgrass, Spartina alterniflora (hereafter cordgrass), a C4 grass that forms monocultures that structurally define inter- tidal marsh habitat (Schalles et al. 2013).

What adaptations does cordgrass have?

California cord grass is adapted to the difficult habitat just below the high tide line, below other saltmarsh plants. In this zone, its roots are often submerged and the soil that anchors them is often low in oxygen. The leaves of California cord grass have a system of elongated, hollow cells.

How fast does cord grass grow?

It is not uncommon for smooth cordgrass to produce 8' to 10' of lateral spread in one growing season. Depending on site conditions and the planting objective, two rows of smooth cordgrass are occasionally planted. A two-row planting will provide quicker and denser short-term coverage than a single-row planting.

What is salt marsh hay used for?

Salt hay grass was harvested for bedding and fodder for farm animals and for garden mulch. Before hay was bailed and stored under cover, salt hay grass was used to top the hay stacks in the fields. Many of the salt marshes in Rhode Island have been severely affected by filling, development, and road construction.

How does Spartina reproduce?

Spartina alterniflora has three methods of reproduction that involve both sexual and clonal processes. It reproduces by seed, rhizome, or vegetative fragmentation (Daehler and Strong 1994). ... When pieces of rhizome root break off, they can sometimes regrow into a new plant that is also a genetic clone to the original.

What is Spike grass?

Spike grass is a short grass often found growing with salt hay grass in higher salt marsh zones. Before it flowers, spike grass is difficult to distinguish from salt hay grass. When in bloom, spike grass has a single, spindle-shaped flower head comprised of numerous individual flowers.

Is smooth cordgrass an invasive species?

Smooth cordgrass is a perennial grass that is native to the Atlantic and Gulf Coasts of North America but is invasive along the Pacific Coast. Hollow stems grow from 2 to 4 ft (0.6 to 1.2 m) tall. Leaves are 8 to 20 in. ... It can hybridize with other spartina species.

How chord grass can live in salty environments?

The complex root system of the smooth cordgrass helps bind it to the banks, preventing the tide from eroding the shoreline. Although it relies primarily on groundwater absorbed through the roots, smooth cordgrass is able to extract fresh water from salt water when the need arises.

What kind of plants are in a salt marsh?

The majority of the area's plants are grasses, sedges, rushes and succulent plants such as saltwort and glasswort. This marsh habitat is an open system dominated by these lower plants – there are, in fact, rarely any trees found within the salt marsh.

Which species of cordgrass is native to California?

Sporobolus foliosus is a species of grass known by the common name California cordgrass. It was reclassified from Spartina foliosa after a taxonomic revision in 2014. It is native to the salt marshes and mudflats of coastal California and Baja California, especially San Francisco Bay.

Why is Atlantic cordgrass a threat?

Hybridization with California cordgrass in San Francisco Bay threatens the existence of the native California species, as it cannot compete with the reproduction and growth of the hybrid.

Is Spartina foliosa invasive?

The invasive species, Spartina alterniflora, created an even more adaptable hybrid with its relative, the bay's native marsh plant, Spartina foliosa. The hybrid threatened to turn tidal mud flats into meadow, eliminate shorebird foraging habitat, and push the native S. foliosa toward extinction.
