Site WN3 at Darling Point appears to be in the best condition, as seagrass abundances have continued to increase against a background seasonal trend. Halophila spinulosa have been recorded at depths of 10m offshore of Moreton Island, highlighting the importance of maintaining good water clarity in the region. WP2 is close to King Island. Biological and habitat monitoring Coral monitoring Introduced aquatic pests Turtle monitoring Riparian vegetation Seagrass. Moreton Island Principal watchers: It is one of Queensland’s most important natural, recreational, cultural and economic resources. Results are summarised in annual report cards. It uses rigorous science to quantify and evaluate waterway health using a range of biological, physical and chemical indicators.

Monitoring at other sites shows no significant changes in abundance or species composition Macroalgae is generally more abundant at PP1 than at the other sites. Seagrass-Watch is the largest scientific, non-destructive, seagrass assessment and monitoring program in the world. Insufficient data to comment on seasonal trends, but generally appears to be higher abundances in the summer months. Peel Island area has relatively good water quality with low nutrient levels and low sediment loads EHMP The main population centre is Caloundra in the north, with the smaller townships of Beerburrum, Beerwah and Landsborough located in the hinterland. The number of turtles with tumours has also increased.

The Bay features a diversity of foreshore and offshore seascapes and landscapes. For further reading, see EHMP Seagrass-Watch data is providing an understanding of seasonal trends and effects of climatic patterns on seagrass meadows. Rapid urbanisation of the catchment has occurred over recent years including the construction of canal developments. Seagrass-Watch raises awareness on the condition and trend of near shore seagrass ecosystems and provides an early warning of major coastal environment changes.

Moreton Bay has a resident population of approximately dugongs. The Mackay-Whitsunday Report Card reports on seagrass abundance, reproduction and nutrient status. The region contains expansive and diverse mangrove forests that are for the most part in good health. Seagrass-Watch monitoring efforts are vital to assist with tracking global patterns in seagrass health, and assessing the human impacts with potential to destroy or degrade these coastal ecosystems.


Major urban and coastal development is occurring in this location. Although the region is affected by the Brisbane River through Boat Passage, water currents generally force nutrients and sediments from the river mouth northward away from Waterloo Bay.

Seagrass (Department of Environment and Science)

Great Barrier Reef Monitoring of seagrass abundance, reproduction, nutrient status is a key component informing the development sseagrass report cards for the Great Barrier Reef. Poor flushing in that area of Deception Bay compounds the impact of this discharge.

Phytoplankton communities are diverse and have adapted to live in low nutrient environments. Contact us Search Department of Environment and Science.

Declared in and extended inthe marine park covers most of Moreton Bay’s tidal lands and tidal waters seawards to the limit of Queensland waters. Areas where seagrass meadows have been lost correlate closely with degraded water quality, particularly from high turbidity.

Seagrass Watch

Approximately 15km2 of seagrass meadows were lost in the southern Bay in following a 1-in year flood wach and there has been no subsequent recovery. The seagrass meadows in the region are shallow and variable, corresponding to the fluctuating water clarity in the system. Macroalgae are persistent at Victoria Point.

This could also be a seasonal occurrence, as Halophila ovalis is a colonising species and such species changes have been observed at similar locations. A few plants of Halophila spinulosa were reported in late at the Darling Point site.

The views expressed on this site are those of the authors and not necessarily those of the program’s supporters. The marine park allows most people to do most things while still protecting the natural environment. The eastern channels, especially Canaipa Passage, which are less influenced by Logan River, have healthy seagrass meadows and greater biological diversity than the rest of the system corresponding to better flushing and excellent water quality.

NS1 is in One Mile Harbour. Due to numerous shallow, muddy channels and its proximity to the Logan River mouth, the area has typically poor water clarity, fair water quality and poor to fair biological health EHMP Home Topics Management and regulation Water quality and ecosystem health Biological and habitat monitoring. University researchers and Seagrass Watch Australia also assess the health of seagrass communities. The number of turtles with tumours has also increased.

To date, 52 sites have been established at 11 different locations. Tingalpa Reservoir impounds Tingalpa Creek. Since Novemberindividuals have applied to volunteer for Seagrass-Watch in Moreton Bay, providing enough people to establish 95 monitoring sites, if each site has two volunteers.

Water quality is however improving, as Deception Bay moretin characterised by fair to good water quality and good biological health EHMP Insufficient data to comment on seasonal trends, but generally appears to be higher abundances in the summer months. Sites NS2 and NS4 generally have more macroalgae present than the other sites.

Fisherman Islands Principal watchers: Examples of seagrass monitoring programs include: Seagrass depth range monitored at Fisherman Islands at the end of Boat Passage as part of the EHMP, is the shallowest, corresponding to the poorest water clarity in the region. The sewage nitrogen signal from poor riverine discharge is also a concern for the region. On the eastern banks of Waterloo Bay, on the western side of Wellinton Point.

Although not currently monitored by EHMP, deep-growing species e. Moretoj site MI2, has been visited on 3 occasions, and seagrass cover has increased significantly.
