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.

How does Spartina reproduce?
It reproduces by seed, rhizome, or vegetative fragmentation (Daehler and Strong 1994). It produces inflorescences containing spikelets which hold seeds that generally develop in July through October.
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.
Where is Spartina alterniflora invasive?
Spartina alterniflora is an invasive plant on the coast of China that replaces native vegetation and has a serious negative impact on local ecosystems.
Why is cordgrass 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]. The presence of smooth cordgrass indicates sites with high salinity, which can be managed for shrimp ponds [20].
Are cordgrass true marine species?
California cordgrass is also called Pacific cordgrass. It is a California native, a perennial, and a coastal saltmarsh facultative halophyte, that is, it tolerates salt but salt is not a requirement for its growth.
Where is Spartina native?
Native Distribution: Atlantic Provinces of Canada south to coastal Texas and south to South America. Zones 5 to 9. Native Habitat: Salt and brackish tidal marshes (mid-tide up to Mean High Tide level).
Why is Spartina alterniflora important?
S. alterniflora is a dominant species in its native range, the salt marshes of the Atlantic and Gulf coasts of the USA. It plays an important role in sediment stabilization and serves as nursery grounds for estuarine fish and invertebrates.
How does Spartina or cordgrass get excrete excess salt?
alterniflora from the other salt marsh grasses. Flowering inflorescence of Spartina alterniflora. It is also able to deal with the high salt levels in the water by excreting excess salt through its leaves. In fact, you can see and feel the resulting salt crystals on the surface of its leaves when this occurs.
What does smooth cordgrass 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 Spartina alterniflora spread?
alterniflora is a plant of the intertidal zone, where it colonizes mud or sandflats in saline or brackish water. The Western Aquatic Plant Management Society (2004) reports that, \”Spartina alterniflora can spread by seed, rhizome, or vegetative fragmentation (Daehler and Strong 1994).
