What is an estuary?
An estuary is somewhere that may be a temporarily or permanently exposed to the sea and subject to tidal changes. They can be as big as Sydney Harbour or small lakes and lagoons.
Estuaries are the heart of range of ecosystems and are constantly changing. They are the nursery grounds for many fish species we see in Jervis Bay and which our dolphins feed on.
Estuaries are super important for filtering water and keeping our special bay pristine!
These habitats provide places for thousands of bird species to live and migrate to. Some visiting birds have traveled far and wide and are even protected by international agreements like RAMSAR.
