Curl Curl Lagoon Brackish Water Lab

Curl Curl Lagoon sits in a middle zone. Rain and creeks push fresh water in, while the sea influences the system from the coast. That means the water chemistry can change with rainfall, tides and lagoon openings. For children, this is a useful reminder that ecosystems are not always neatly sorted into categories. Some habitats live in the in-between.

Those in-between habitats can be especially rich because they offer food and shelter to many kinds of animals, but they are also stressful places to live. Plants and animals here need to cope with changing salinity and water levels. That makes lagoons powerful teaching tools. Stability is not the only path to life. Sometimes resilience comes from adapting to constant change.
