Estuarine ecology

Esturarine wetlands are located in areas where a river, or other freshwater source, meets the sea. They provide an important habitat for a range of species. Many commercial species such as fish, crabs, prawns etc. start their life in estuarine areas. Mangroves are usually the most common vegetation as they are specially designed to deal with the high levels of salt found in the water and the often water-logged environment. These areas are also important when it comes to protecting the coastline from storm surges, cyclones etc.

Quick facts

Brisbane River

is the longest estuary in South East Queensland. Over time, removing the sand bar at the mouth of the river and long-term dredging has increased the oceans tidal reach to nearly 90km upstream[1].
