4.6.3. Life in Estuary


Only certain types of plants and animals specially adapted to the “brackish” estuarine waters flourish in the estuaries. Factors influencing the growth and distribution of organism in an estuary are its salinity and the amount of flooding.

Estuaries are homes to all kind of terrestrial or landbased plants and animals, such as wood storks, pelicans, coniferous and deciduous trees and butterflies. Estuaries are also homes to unique aquatic plants and animals, such as sea turtles and sea lions, sea catfish, saltworts, eelgrass, saltgrasses, cordgrasses, sea grass, sedge and bulrush.

Predators are important to the estuary because of their end position in most consumer food chains.
