About Moreton Bay

Seen from Space, Moreton Bay shines like a jewel adorning the most easterly part of Australia, reflecting many shades of blue, a natural marine wonderland. Bounded by three main islands protecting it from the Pacific Ocean, Moreton Bay is as a tidal lagoon with clear, calm and shallow waters dotted with many, many islands. Aboriginal Australians of the ‘Land Sea Country’ call it “Quandamooka” and evidence of their occupation goes back perhaps 25 000 years.

Extending from the fore-shores of Brisbane, Moreton Bay is internationally recognized for biodiversity and ecological significance. It encompasses unique subtropical reefs and a Ramsar wetland. It is a transitional area where tropical, sub‐tropical and temperate marine species co‐exist, resulting in distinctive habitat and wildlife communities. Moreton Bay is considered one of the most significant marine habitats on the entire east coast of Australia. The hinterland features areas of World Heritage sub-tropical rainforests.

South-east Queensland’s rapidly expanding population – amidst this ‘bio-diversity hot-spot’ – places increasing pressure on Moreton Bay through more pollution, more boat traffic and more coastal development.

Moreton Bay Marine Park

On Brisbane’s doorstep, the wide expanse of Moreton Bay, offshore reefs, its numerous islands, internationally significant wetlands, seagrass meadows and sandy beaches make this park a haven for wildlife and people.

Moreton Bay Marine Park protects a range of marine and coastal environments including rocky shores, internationally significant wetlands, coral reefs, mangroves, seagrass meadows and sandy beaches. These habitats provide important seasonal resources for migratory wading birds, humpback whales and marine turtles. Permanent resident species include dolphins, dugong, shorebirds, grey nurse sharks and various fish species.

http://www.nprsr.qld.gov.au/parks/moreton-bay/

The Moreton Bay Marine Park was established in 1993 and re‐zoned in 2009, expanding coverage of no‐take zones to 16%. The Park is again due for review in the next few years. Both commercial and recreational fishing activities are notable considerations.

Very detailed maps of different parts of the bay are in the Marine Park User Guide here:

Catchments of Moreton Bay


.. a good dozen rivers flow into Moreton Bay, their upper reaches originating 100kms or further away. Increasing millions of people live within their watersheds,  all affecting water quality in the bay.

Healthy Waterways

South East QLD waterways are under increasing pressure from a rapidly growing population and unpredictable climate. The major issue affecting waterway health is the increased amount of mud (or sediment) entering  waterways – and nutrients – and litter are also a serious pollution problems affecting waterways, wildlife and recreation.

Healthy Waterways works to understand and communicate the condition of the waterways to drive and influence future targets, policy and actions. Healthy Waterways was built on a foundation of rigorous science which continues to underpin the organisation’s programs and initiatives.

A forest of papers going back decades supports these assertions. There is an extensive searchable public record of how today’s efforts to monitor & manage waterways have evolved. See for example a long list of papers about water quality from QLD’s Department of Environment and Heritage Protection here: https://www.ehp.qld.gov.au/water/monitoring/publications.html

Shorebirds

Moreton Bay is one of only three extensive intertidal areas of seagrass, mangroves and saltmarsh on the eastern coast of Australia that provide habitat for waterbirds. It has high species diversity recorded, with 27 species being recorded only from Moreton Bay. (Davies et al 1998). More recent information below.

Resident seabirds and shorebirds include herons, terns, oystercatchers, egrets and cormorants and each year Moreton Bay is visited by 50,000 migratory shorebirds. Some travel as far as Siberia and back. From October to April – more than 30 different shorebird species live in this area busy feeding to build up energy for their return trip to East Asia.

Australia is signatory to international agreements protecting significant wetlands and also migratory birds.

Dugongs, Turtles and Seagrass

50% of Australia’s seagrasses have been destroyed by dredging and pollution.
http://www.wildlife.org.au/projects/seagrass/

Seagrasses are the primary food source for dugongs and sea turtles. An adult green turtle eats about two kilograms of seagrass a day while an adult dugong eats about 28 kilograms of seagrass a day. Moreton Bay is a significant habitat for loggerhead and other sea turtles – the most important population along the east coast of Australia.

http://www.nprsr.qld.gov.au/parks/moreton-bay/zoning/information-sheets/turtles.html

Moreton Bay Marine Park is home to 7-8 different species of seagrasses which together cover 25,000 ha of deep and shallow water areas. Since 1987, Moreton Bay Marine Park has lost a staggering 20% of seagrasses, which means lost productivity and loss of turtle and dugong food.

Historically, herds of dugongs grazed on seagrass meadows throughout the entire bay, however, extensive loss of seagrass meadows on the western side of the bay,  has largely reduced suitable grazing areas for these animals. As a result, their distribution is primarily restricted to seagrass meadows in Eastern Moreton Bay. Population statistics range from 1500 down to 6-800 with the lower range more likely.

Mangroves

Scientists estimate that 75% of the commercially caught fish and prawns in Queensland spend at least some part of their life cycle living in the mangroves.

Mangrove forests play an active role in nutrient recycling and provide nurseries for juvenile fish, crabs and prawns.  In Moreton Bay Marine Park, 7-8 species of mangroves occupy around 15,300 ha.

http://www.savemoretonbay.org.au/pages/mangroves.html

The shallow nature and vast intertidal zones of the southern half of Moreton Bay, makes it one of the world’s significant wetland environments.

Corals

Moreton Bay Marine Park is fortunate to have some of the most southern located reef-building corals on the East Coast of Australia. The bay and surrounding area, including Flinders Reef, has up to 173 species in 42 genera, about a quarter of all species of the Indo-Pacific. A high proportion of these have growth-form variations seldom seen elsewhere.

http://www.nprsr.qld.gov.au/parks/moreton-bay/zoning/information-sheets/coral.html

Coral Watch (www.coralwatch.org ), Reef Check (www.reefcheckaustralia.org ), the UQ UniDive Club (http://www.unidive.org/unidive‐projects/)  and other groups and individuals conduct surveys and monitor health of underwater communities at Moreton Bay sites.

An Ecological Assessment around Point Lookout, North Stradbroke Island was conducted during 2015.

Barrier Reef coral scientist Dr John ‘Charlie’ Veron has dived on the Great Barrier Reef for 45 years. He has identified 20 per cent of the world’s coral species and earned himself a reputation as the “Godfather of Coral.”

“Unknown to most people, Moreton Bay has an extraordinary diversity of corals [and] the coral communities of Moreton Bay are so unusual they have few parallels anywhere in the world and none in Australia. This observation can hardly be overstated. For example, the most recently discovered of all corals, Heteropsammia moretonensis, is found nowhere else. For another example, I named Astreopora moretonensis after the region because it is common and forms large colonies there, but is rarely seen elsewhere. The word ‘unique’ is often overplayed but the corals of Moreton Bay are indeed that, to an exceptional degree.”

Threats to Moreton Bay

South-east Queensland’s rapidly expanding population places increasing pressure on Moreton Bay through more pollution, more boat traffic and more coastal development. 5.5 million people are projected to live near Moreton Bay catchments by 2050:

Massive new developments such as the Toondah Harbour proposal are planned:

http://toondah-harbour.com.au/

Each year threatened turtles and dugongs are injured or killed from pollution, boat strike and marine debris within Moreton Bay Marine Park. These and many other issues from the disappearance of Shorebirds, water quality, threats to Fishing are explored in greater detail on many other links and other websites. Please let us know about errors or anything we might have missed.
