Seagrass on Nudgee Beach (BB3) – first time seen since monitoring began in 2003

Some good news.

Seagrass has not been seen on Nudgee Beach for many years.   See the below graph.

Nudgee Beach is located in Bramble Bay and WPSQCCS have been monitoring this site since 2003.

A WPSQCCS seagrass monitoring team on the 23 March 2019 found several patches of seagrass within the inundated gutters on the beach.

Both  Zostera muelleri ssp. capricorni and Halophila ovalis were found on the beach. See the below photographs.

This comes with recent news that local scientists had found sub-tidal seagrass recovering within Deception Bay, just to the North of Bramble Bay.

While the patches of seagrass found at Nudgee Beach are small they appear healthy and therefore it may signify some form recovery, which is encouraging.

Free public talk – Peel Island, Moreton Bay – a look at its unique history

Peter Ludlow, author historian, has been researching and writing about the unique history of Peel Island since 1977.

Peel Island is a green jewel situated in Moreton Bay.  Beautiful beaches, coral and bushland. It also has an interesting history.

The Peel Island Lazaret, in Moreton Bay, was established for the detention and treatment of suffers from Hansen’s Disease, more commonly known as leprosy. Opening in 1907, Peel Island Lazaret was Australia’s first purpose-built, multi-racial lazaret in Australia. It was run by the Queensland State government and closed in 1959.

With his PowerPoint presentation, Peter highlights Peel’s history including pre-European occupation, its use by Europeans and, in 2007, the Island being gazetted as a National Park and Conservation Park and the Lazaret Buildings being Heritage Listed.

Venue: Indigiscapes 17 Runnymede Road, Capalaba 7:30pm 25th August, 2017.

 

 

 

The impact of turbidity on seagrass and other marine life

Historically, dugongs and turtles grazed on seagrass beds within Bramble Bay, but high turbidity and nutrients eliminated these beds at least 30 years ago. Current water quality conditions of Bramble Bay are unsuitable for the re-establishment of seagrass meadows. Nitrogen in the Bramble Bay zone has been decreasing since the upgrade of the Luggage Point Waste Water Treatment Plant (WWTP) in 2001. However, poor flushing continues to contribute to the poor condition of this catchment, the area possessing the longest residence time of Moreton Bay (59 to 62 days).

Deception Bay is situated at the northern section of Moreton Bay from Newport up to the south of Bribie Island and receives input from the Caboolture River, Pumicestone Passage and several other streams including Burpengary Creek.

Extensive seagrass meadows are present in the northern part of the bay but have been threatened by toxic Lyngbya blooms. Lack of seagrass recovery is likely due to discharge of poor quality water from the Caboolture River which remains a pressure on Deception Bay’s overall ecosystem health. Poor flushing resulting in turbidity in that area of Deception Bay compounds the impact of this discharge.   Since 2002 Healthy Waterways has monitored 9 sites within the Deception Bay reporting zone.

Seagrass Monitoring data from Wildlife Queensland Coastal Citizen Science has enabled the processing of Landsat imagery (USGS product) to understand the impact of Turbidity upon seagrass in Deception Bay. The negative impact is quite clearly seen in Sheet 10 of https://public.tableau.com/profile/wpccs#!/vizhome/mbay-sgw/Dashboard1  

A recent seagrass survey at Ormiston (Moreton Bay) noted turbidity impacting upon the coral reef located adjacent to the monitoring site.   This area supports coral gardens but they are under threat from too much turbidity. If we want to protect these amazing coral gardens we need to improve our land management within the catchment, starting with protecting natural vegetation.

 

Two great speakers at Wildlife Queensland Bayside meeting – 30th June 7:30pm – talking about Gliding Marsupials

Free public talk about Australia’s gliding marsupials.

Friday 30th June 2017  7:30pm at Runnymede Road, Indigiscapes Capalaba, just off Redland Bay Road.

Our Speaker is Matt Cecil from Wildlife Queensland and Jenny Davis from Redland Council.  They will be talking about our local gliding marsupials.

All six species of Australian glider are found in Queensland, five of them in the south-east of the State. They range in size from the tiny feathertail glider, which can sit in a child’s hand, to the solitary and regionally vulnerable greater glider.

Come along to a free night of great talks and hear about our local gliders and about the great work that is being done by the Queensland Glider Network  who is helping protect these unique and beautiful creatures for future generations.

A light supper is provided.

Extreme climate events – heatwaves, floods, windstorms and bushfires – can quickly become disasters if communities aren’t prepared. Extremes are how we will feel the climate changing – more so than creeping averages. So how do we prepare for these dramatic events? Join our webinar panel looking at projections of extreme climate in the future, the impacts these events may have on our built environment and communities, and how we can adapt.
