Mangrove Watch

Mangroves and tidal saltmarshes are amongst the most endangered marine wetland habitats worldwide.

‘MangroveWatch’ is a program that has been established to address the urgent need to preserve and protect threatened tidal wetland ecosystems as well as addressing both scientific and environmental management needs.

This new monitoring program targets estuarine and coastal systems where there are mangroves, saltmarsh and saltpans. Like Seagrass-Watch the program uses a partnership between community volunteers and scientists.

No mangroves – no fish!

Mangroves are essential habitat where bountiful and beneficial fish live, feed and breed. Mangroves nurture 75% of Queensland’s fish catch.

Healthy mangroves – healthy catchment!

Responsive mangroves act as end-of-catchment indicators. Mangroves show the effects of runoff sediments, nutrients and agricultural chemicals.

‘Coastal kidneys’ – protect the Reef!

Coastal mangroves protect the Reef by filtering catchment runoff, and reducing shoreline erosion. Healthy mangroves support healthy corals with clearer, cleaner water - lower in sediments and chemicals.
