Estuaries are semi-enclosed waterbodies with open or intermittently open connections with the ocean 1. They are the tidal portion of a waterbody, and the area where freshwater draining from the catchment mixes with ocean waters 2. The Hunter Estuary is the tidal portion of the Hunter River. The estuary extends up to the tidal limit of the Hunter River at Oakhampton 65km from the oceanthe Paterson River at Gostwyck 75km from the oceanand the Williams River at the Seaham Weir 46km from the ocean.
The Hunter Estuary is one of the most complex estuaries in NSW to manage because it is subject to a range of pressures from mining, agriculture, industry and urbanisation, but is also home to internationally important shorebirds and wetlands. Seagrasses which are marine plants that look like grasses Two species of mangrove can be found in the Hunter Estuary, including the River Mangrove Aegiceras corniculatum and the Grey Mangrove Avicennia marina River Mangroves can be identified by their brown bark and rounded tips of the leaves Grey Mangroves have grey bark, a pointed tip on their leaves and above ground roots called pneumataphores Mangroves provide valuable food and habitat for a range of animals, especially fish.
Saltmarsh is a threatened species that is protected at both the state and federal level. Saltmarsh provides valuable food and habitat for a range of animals, especially birds including migratory shorebirds. Seagrasses are different Hunter river nsw seaweed Seagrasses are land plants that have moved into the marine environment Unlike seaweed, Hunter river nsw flower and can absorb nutrients from the sediments. The Hunter Estuary does not have any seagrass Small areas of Sea Tassel Ruppia spp. Seagrass has not been seen in the Hunter River for the past 45 years All other rivers similar to the Hunter River in NSW have seagrass, so it is thought that the Hunter River would have historically had seagrass The reasons for the absence of seagrass in the Hunter River are not well understood, however it is thought that high turbidity and poor water quality may be contributing to the lack of seagrass.
Another important type of estuarine vegetation found in Newcastle is Swamp Oak Casuarina glauca forest. Swamp Oak forest is a threatened species which is protected by state legislation. Further information about this threatened species can be found at the Office of Environment and Heritage website.
Revegetation Works Council, Landcare, and others are undertaking ongoing revegetation works around the estuary. The goals of Council's ongoing revegetation works are to:. A of ificant wetland conservation projects are being undertaken by other stakeholders within the Hunter Estuary including the Hexham Swamp Rehabilitation Project, Kooragang Wetlands Rehabilitation Project and Tomago Wetlands Restoration Project.

We respect their cultural heritage, beliefs and continuing relationship with the land, and recognise that they are the proud survivors of more than two hundred years of dispossession. City of Newcastle reiterates its commitment to addressing disadvantages and attaining justice for Aboriginal and Torres Strait Islander peoples of this community.
Hunter Estuary. The Hunter Estuary. What is an Estuary? The Hunter Estuary is Hunter river nsw important that it is internationally recognised. The wetlands are protected because they are home to a of threatened and internationally important species. A migratory shorebird called the Latham's Snipe Gallinago hardwickii is of particular interest to the two countries. The Latham's Snipe breeds in the Kushiro wetlands and migrates to the Hunter Estuary over the Australian summer to avoid the harsh Japanese winter. Shorebirds are birds that are regularly found along our coastal and river shorelines.
Shorebirds can be migratory fly overseas or non-migratory stay in Australia. Migratory shorebirds can travel over 20,km in a year. The Bar Tailed Godwit has been tracked flying non-stop for 11, kilometres over nine days 3. Our estuary is one of only 20 sites in Australia that forms part of the East Asian-Australasian Flyway 5. There are 23 countries within the flyway, and 54 species of migratory shorebirds use the flyway 6.
The East Asian-Australasian flyway is one of nine flyways across the world that is used by migratory shorebirds 6. The Hunter Bird Observers Club undertook a study in to identify the bird species that can be found in the Hunter Estuary. The decline in bird s is due to both local and international issues, with the leading cause of decline being habitat loss 7.
In the Hunter Estuary, large areas of mudflats have been lost to land reclamation and the expansion of mangroves, which has considerably reduced the habitat available for shorebirds 7. Grey-tailed Tattler Tringa brevipes Source HBOC As migratory shorebirds rely on habitats in different countries to survive, they require international protection.
In Australia, migratory shorebirds are protected by Federal legislation called the Environment Protection and Biodiversity Conservation Act Unfortunately, the frog is now very rare and is protected at a state and federal level 8. The frog is now limited to 43 isolated key populations in NSW 8. The frog population in the Hunter Estuary is under threat from industrial development, increased saline inundation, disease Chytrid funguspredation by introduced pests, and poor water quality 9.
Key vegetation types found within the Hunter Estuary include: Mangroves which are a group of trees and shrubs found in the intertidal zone between the land and river 10 Saltmarsh which is a community of grasses, herbs and shrubs found in the intertidal zone 11 Seagrasses which are marine plants that look like grasses The goals of Council's ongoing revegetation works are to: Protect and enhance shorebird habitat Protect and enhance native estuarine habitat values, and threatened vegetation species Minimise the impacts of weeds and pests.
Some examples of the works Council has undertaken are shown below. Council has prepared a of documents to identify the issues impacting on the estuary, and the management actions that should be Hunter river nsw to address the issues. Council undertakes priority works listed in these documents on an ongoing basis. The Hunter Estuary Management Study outlines potential management actions for addressing the key issues impacting on the estuary. The Study was developed after extensive community consultation.
The Hunter Estuary Coastal Zone Management Plan contains the list of agreed management actions that Council, and others, aim Hunter river nsw implement over time. The Newcastle Coast and Estuary Vegetation Management Plan prioritises on ground works to protect estuarine plants and animals in Newcastle. Council is working with a of stakeholders to develop a water model for the Hunter Estuary. For further information about the model please see the World First Model. Blackbutt Reserve Visit website.
