Western Port has retained 90-95% of its pre-1750s mangrove habitat that was estimated at 1320ha. Losses have been caused by harvesting, land claim for industrial and port development and the drainage of adjacent land.
Corner Inlet and Nooramunga: Mangroves are at their southern-most limit in Corner Inlet and Nooramunga where 80% of the pre-1750s cover remains.
Other marine and coastal areas: On a statewide basis, 90% of the pre-1750 extent of mangroves remains and their spatial extent may be expanding in response to climate change.
There are insufficient data to determine condition of mangroves.
