What conditions are salt marsh plants adapted for?
Plant Adaptations Perched between terrestrial and marine environments, salt marshes are biologically diverse communities adapted for harsh environmental conditions including flooding, low oxygen (anoxia), salinity fluctuations and extreme temperatures.
What type of vegetation dominates salt marshes?
smooth cordgrass
The salt marsh grass known as smooth cordgrass dominates the lower marsh ecosystem, which is closest to the sea. The plant’s narrow, tough blades and special glands that secrete excess salt make it well adapted to brackish water. Smooth cordgrass provides shelter for many fish and small animals.
Can plants grow in salt marshes?
The most common salt marsh plants are glassworts (Salicornia spp.) and the cordgrass (Spartina spp.), which have worldwide distribution. They are often the first plants to take hold in a mudflat and begin its ecological succession into a salt marsh.
What are marsh plants?
marsh, type of wetland ecosystem characterized by poorly drained mineral soils and by plant life dominated by grasses. The number of plant species in marshes is few compared with those that grow on well-watered but not waterlogged land. Grasses, grasslike sedges, and reeds or rushes are of major importance.
What is the role of salt marsh grasses?
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.
What is the purpose of salt marshes?
By filtering runoff and excess nutrients, salt marshes help maintain water quality in coastal bays, sounds, and estuaries. Salt marshes provide important habitat for a variety of birds, including popular waterfowl and imperiled species such as the Eastern black rail, wood stork, and saltmarsh sparrow.
How do salt marsh plants deal with salt?
Salt wort leaves seem to accumulate salt; then the plant drop the leaves as a way of disposing excess salt. Leaves fold up to reduce water loss. This is a common characteristic of grasses: Compare leaves of salt grass where they are wet and where they are much drier.
What kind of organism is salt marsh grasses?
The dominant grasses in a salt marsh are of the genus Spartina. The large amount of food produced by both living and decaying plants provides nutrients for many young fish and crustaceans. Salt marshes are considered the nurseries of the sea.
What is the climate of a salt marsh?
Effects of Temperature on the Salt Marsh Average monthly winter air temperatures range between 38-59° F (3-15°C). Average monthly summer air temperatures range between 70-90°F (21-32°C). Rainfall varies along the Southeast coast; however, it averages around 50 inches (1,270mm) per year.
