General Seagrasses occur in coastal marine and estuarine habitats, generally in near shore, soft substrates. There are five common genera of seagrasses found along the temperate Australian coastline (Posidonia, Heterozostera, Zostera, Amphibolis and Halophila), with the greatest diversity found in Western Australia. Ecological significances of seagrasses include to their ability to trap and stabilise sediments; provide nursery areas for juvenile fish; encourage larvae settlement; provide protection from predation; assist in nutrient cycling; and transfer energy into the food web. Direct human impacts such as mechanical damage, eutrophication, aquaculture, siltation, coastal constructions, and alteration of food webs; along with indirect human impacts including impacts of climate change have contributed to a widespread loss of seagrass. Natural disturbances such as storm events, extreme wave-action, predation and disease also contribute to loss.
