Reeds and grasses are the dominant type of plant in estuaries because they are able to tolerate and grow in the salty water. land and salt water. The energy inputs for this deposition and estuary compartments can be seen below: The outer (seaward) zone receives most wave and tidal current energy. Plant life in estuaries The salt marsh region of the estuary is characterized by plants that are adapted to salty conditions. This area has a Mediterranean climate with warm, dry summers and cool, wet winters. The plants which fringe the estuaries are highly adapted to a dynamic environment. V.B.1 Wave-Dominated Estuaries.

Unfortunately, these rare but highly productive areas are also very fragile, and human encroachment has compromised their ability to provide . In tropical estuaries, mangroves are the dominant producers. Estuaries harbor unique plant and animal communities because their waters are brackish—a mixture of fresh water draining from the land and salty seawater. However, estuaries respond differently to variations in river flow, depending on bathymetry, tidal currents, and wind. The dominant plant groups in our estuaries are seagrass, mangroves, saltmarsh, macroalgae and microalgae.

Estuaries - The Cradle of the Ocean. As more mud is trapped, decaying plants help build up a soil so that plants such as cord grass, sea lavender and sea aster can grow . Tide-dominated estuaries are typically open to the sea, are characterized by sand, and may develop in any tidal range. Reeds and grasses are the dominant type of plant in estuaries because they are able to tolerate and grow in the salty water. The great floral variety of the Everglades is one of the key resources of the park. An estuary may also be called a bay, lagoon, sound, or slough. Also in the Bay, there is submerged aquatic vegetation where seahorses, blue crabs, and other fish . In estuaries, the salty ocean mixes with a freshwater river, resulting in brackish water.
