Art, science and culture are all coming together in a beautiful series of seagrass-inspired artworks, on display at Aspects Gallery Shop in Kings Park. The artworks by Tiahna Oxenham, Sabrina Dowling Giudici, Nadja Roelofs, and Kelly Osborne are all inspired by marine environments, featuring seagrasses.
‘Black water’: The three Australian sites that are ground zero for climate change
In the summer of 2011, as flooding across Victoria and Queensland killed 35 people and left a $14 billion damage bill, something very different was happening on the other side of the country. Record summer ocean temperatures up to 5C above average represented the worst marine heatwave Western Australia had ever seen.
Funding boost for young marine researchers
Congratulations Maria Jung - one of eight young researchers to receive a major boost to support for doctorate research in marine science. Working across a diverse range of innovative projects in ocean science, the eight PhD students were awarded a total of $92,000 through the 2020 Robson and Robertson Awards Scheme.
A Snapshot of 70 Years of Marine Research in Shark Bay: Ecological, Social and Economic
A new report launched this week by the Western Australian Marine Science Institution brings together the last seven decades of marine research on Gathaagudu, Shark Bay. Gary Kendrick hands the Report over to Malgana Traditional Owners.
Blue carbon, conservation economies & the great seagrass restoration
Gary Kendrick’s great love is the WA coastline and its seagrasses. Gary and colleagues have been at the forefront of seagrass restoration and the blue carbon movement more broadly. And with such a massive extent of coastline featuring globally significant carbon stores, World Heritage Sites, and deep community and cultural knowledge, the potential for WA is enormous.
Steady strides to conserve waterways
With the future of fishing in Australia directly related to the quality of our waterways, one national not-for-profit has put the call out for recreational fishers to help conserve their beloved streams, lakes and estuaries.
Restoring seagrass for snapper
An experiment to restore seagrass in order to attract pink snapper close to shore is proving to be a success. John Statton discusses restoring seagrass in Cockburn Sound with GWN7.
Snapper habitat gets second dose of seagrass seeds
West Australian recreational fishers and divers have worked to restore the lost seagrass meadows of Cockburn Sound for the second consecutive year by collecting and spreading seeds to speed the plant’s restoration and improve the habitat for Pink Snapper.
Malgana people add their voice to science priorities for Shark Bay
Generations of Malgana people from Gatharragudu (Shark Bay) came together to start the process of understanding the decades of research that has been carried out in the World Heritage Site and to develop priorities for the future. Matt Fraser got the opportunity to share seagrass research firsthand.
Australia's Great Southern Reef newest 'Hope Spot'
Mission Blue founder Sylvia Earle announces their latest Hope Spot: Australia's Great Southern Reef.
PhD researcher Sahira Bell explains that despite 70% of Australians living within 50km of the GSR, public knowledge of the Reef is scant.
Shark Bay: A World Heritage Site at catastrophic risk
The devastating bleaching on the Great Barrier Reef in 2016 and 2017 rightly captured the world’s attention. But what’s less widely known is that another World Heritage-listed marine ecosystem was also devastated by an extreme marine heatwave in Western Australia in 2011. Safeguarding Shark Bay from climate change will require a coordinated research and management effort from government, local industry, academic institutions and local Indigenous groups.

Momentum builds to save seagrass as it disappears at a fast rate
‘Operation Posidonia’ launched in Port Stephens today. A team led by UNSW and the Sydney Institute of Marine Science is asking local communities to help restore endangered Posidonia seagrass meadows by collecting shoots that naturally become detached after large storms. Listen to the radio interview.
'Seeds for Snapper' restoring the seagrass meadows of Cockburn Sound
In an Australian first, hundreds of West Australian recreational fishers will be asked to take part in a trial to restore the lost seagrass meadows of Cockburn Sound. Cockburn Sound has lost some 80% of its seagrass habitat since the 1960’s, down from 4000ha originally, to 900ha today. OzFish Unlimited is leading this trial, with support from Recfishwest and researchers from the University of Western Australia, along with BCF.
Climate Issue: Losing Earth
The New York Times Magazine dedicated this issue to a single long story, 'Losing Earth: The decade we almost stopped climate change', by writer-at-large Nathaniel Rich with amazing photographs and videos by George Steinmetz, about the ten-year period from 1979 to 1989, the decisive decade when humanity settled the science of climate change and came surprisingly close to finding a solution. The world was ready to act. But we failed to do what was necessary to avoid a catastrophe. Rich's story is a gripping narrative that reads like a historical whodunit.
Adapting to ecosystem change in the Shark Bay World Heritage site
Five years after the release of a report into the Shark Bay World Heritage site recommended a coordinated collaborative approach was vital to understand changes in the ecosystem, more than 70 science and industry experts have joined forces to examine the threats and prioritise the research needed to save its status.
Climate change threatens world's biggest seagrass carbon stores
A new study published today in Nature Climate Change by an international team of researchers highlights the devastating effects of a marine heatwave in one of the world’s largest remaining seagrass ecosystems. This collaborative study found the death of seagrasses in the Shark Bay World Heritage Site from a 2010/11 marine heat wave released up to nine million metric tons of carbon dioxide (CO2) into the atmosphere over the following three years.
Study finds ways to avoid hidden dangers of accumulated stresses on seagrass
Hundreds of millions of cubic meters of vital seagrass meadows worldwide can potentially be at risk of collapse from accumulated effects of repeated dredging and natural stress - a QUT-led research project examines just what the main risks are in a newly published article in the Journal of Applied Ecology.
Seagrass research included in $14.75 million of Federal funding
Researchers at The University of Western Australia have received $14.75 million in funding for 26 projects through the Federal Government’s Australian Research Council. UWA received $9.6 million for 25 Discovery Projects including:
Saving seagrasses from dredging - new research finds solutions
Timing of dredging is the key to helping preserve one of the world’s most productive and important ecosystems - seagrass meadows. The study, published overnight in Nature Communications, was led by QUT researchers in collaboration with seagrass experts at ECU, JCU, and UWA.
Study identifies bottlenecks in early seagrass growth
Seagrass meadows, key nursery and feeding grounds for many kinds of marine life, are being lost worldwide to nutrient pollution, warming waters, and other ills. A new study published today by an international research team reveals bottlenecks in the growth of seagrass from seed to seedling, knowledge useful for improving seed-based restoration efforts.
Vale Professor Arthur McComb
On Sunday 8th October we lost a great champion for Australia’s aquatic environment with the passing of Professor Arthur McComb. Arthur has been instrumental in the growth of aquatic ecosystem science in Australia. The underlying theme of Arthur’s research was to understand the fundamental processes that control plant biomass in aquatic systems and the place of primary producers in the functioning of whole ecosystems. Arthur’s legacy will live on through his writings and his many students.
Are Coral Reefs on Death Row? A masterclass with Charlie Veron
Members of the Kendrick lab were privileged to spend the morning in a Masterclass with Charlie Veron. We covered topics from coral taxonomy, biogeography, ancient mass extinctions and the re-evolution of modern corals to reticulate evolution and climate change. Are they facing another mass extinction? - this time at the hands of rapid ocean warming and acidification, largely driven by our human desire to burn fossil fuels? The mornings topics provided for some lively conversation! Thanks to the UWA Institute of Advanced Studies for sponsoring this event.

Western Australian Young Achiever Awards - 2017 finalists announced
Congratulations to Matthew Fraser who was recently named as a finalist for the Western Australian Young Achiever Awards in the Environment and Sustainability category. Matthew created the Cottesloe Ecosystem Research Project where undergraduate students research one component of the Cottesloe Reef ecosystem - plants, invertebrates, or fish. They add data to a pre-existing long term dataset to report on changes, providing valuable monitoring. The winners will be announced at the Awards Gala Presentation Dinner this Friday.
Marbà et al. (2015) selected for Journal of Ecology's new virtual issue
The Journal of Ecology have announced the creation of a new subject category: Global Change Ecology. To mark the occasion, they have prepared a special virtual issue titled 'Plants in a changing world: global change and plant ecology'. The virtual issue consists of 21 of the finest research published on global change over the last few years, including Marbà et al. (2015) 'Impact of seagrass loss and subsequent revegetation on carbon sequestration and stocks.'
WAMSI: Avoiding or reducing dredging during sensitive periods
The Western Australian Marine Science Institution (WAMSI) has just published an article which examines whether dredging operations suspended during generic windows of environmental sensitivity could reduce the impacts on marine life has found the marine invertebrates, seagrasses and macroalgae too diverse to be covered by a one-size-fits-all approach.
Climate-driven regime shift of a temperate marine ecosystem
Ecosystems over time have endured much disturbance, yet they tend to remain intact, a characteristic we call resilience. Though many systems have been lost and destroyed, for systems that remain physically intact, there is debate as to whether changing temperatures will result in shifts or collapses. Wernberg et al. show that extreme warming of a temperate kelp forest off Australia resulted not only in its collapse, but also in a shift in community composition that brought about an increase in herbivorous tropical fishes that prevent the reestablishment of kelp. Thus, many systems may not be resilient to the rapid climate change that we face.
Published: Identifying knowledge gaps in seagrass research and management: An Australian perspective
Gary, Marion, and Liz attended a Seagrass Workshop in July 2015, hosted by Deakin University's Centre for Integrative Ecology. The workshop was held as part of the Australian Marine Sciences Association conference and included over 50 seagrass experts and student researchers. The aim was to update and redefine strategic priorities in Australian seagrass research. Participants identified 40 research questions across 10 fields as priorities. A multidisciplinary approach will be needed to facilitate greater understanding of the complex interactions among seagrasses and their environment.
New generation of scientists
CSIRO has teamed up with BHP Billiton Petroleum and the University of Western Australia to welcome a fresh faced trio of scientists. The new PhD students will be conducting research to protect and conserve one of Australia’s most unique landscapes: the Ningaloo Reef.
What happens when (plant) sex fails?
Many plant species reproduce using sexual and asexual methods – and this can vary depending on environmental and genetic conditions. A large amount of energy goes into producing flowers and seeds for sexual reproduction, while vegetative growth through continuous expansion of the original plant(s) requires much less energy. Sexual reproduction produces new combinations of genes which may be advantageous in changing environments. Yet vegetative growth may also be seen as advantageous through the persistence of the same locally adapted genetic individuals.
Seagrass planting strategy needed to remove fast food option
Efforts to restore Shark Bay’s seagrass meadows by transplanting Posidonia australis at the edge of existing meadows are being hampered because resident fish are using the new seagrass as fast food.
Summer scholarships for young talent
Five young West Australian scientists are spending their summer working alongside researchers at Kings Park and Botanic Garden as part of the Kings Park scholarship program. One of this years successful scholars is Henry Lambert, a UWA zoology and marine science double major, who will be researching alongside Elizabeth Sinclair, learning about the genetics of seagrass restoration.
Why are Australia’s marine parks being reviewed so soon after they were signed off?
The current government review of Australia’s proposed network of marine parks, called the Commonwealth Marine Reserves (CMRs), seems rather premature. After all, the management plans were approved only in March 2013 and as yet only the southeast region is being actively managed.
Tropical seagrass examined for light pressures
Research into seagrass susceptibility to dredging activities has revealed exactly how fragile some of the tropical marine plants species are when faced with a decreased level of light.
Dead whales are expensive – whose job is it to clear them up?
A whale carcass can be a big headache – just ask the locals at Broulee Beach in southern New South Wales, where a dead whale washed back ashore last month despite already having been towed out to sea just after Christmas.
Seagrass loss linked to greenhouse gas emissions
An international team of researchers has found that the disappearance of seagrass meadows could be contributing to the release of carbon dioxide which has been stored for centuries. Researchers studied the impact of disappearing seagrass meadows (Posidonia australis), at Oyster Harbour in Albany, where long-term restoration of seagrass has been highly successful. They used sediment-dating techniques to quantify the accumulation of carbon in repopulated areas and calculate the erosion of carbon in areas that were not revegetated.
Climate change threatens Western Australia’s iconic Shark Bay
In the summer of 2010-2011 Western Australia experienced an unprecedented heatwave — but not on land. Between December 2010 and April 2011, sea temperatures off the WA coast reached 3ºC above average, and for two weeks peaked at 5ºC above average — 28ºC compared to the normal 23ºC. The effects were drastic. Corals bleached, and the makeup of the usually temperate south west marine ecosystems shifted to more tropical — both in fish, and algae.
Seagrasses are considered the forests of the marine world, but they have been in global decline for years, so news that Western Australian researchers have successfully transplanted seagrass is considered a significant development. ABC radio's Desley Blanch speaks with Gary Kendrick.
Researchers sow seeds of seagrass transplant success
Western Australian researchers have had a major breakthrough by successfully transplanting seagrass – considered the forests of the marine world – in a section of Cockburn Sound.
Seagrass meadow restoration trial using transplants – Cockburn Sound, Western Australia
Cockburn Sound is a natural embayment approximately 16 km long and 7 km wide, to the west of the southern end of the Perth metropolitan area. Its seagrass meadows have been reduced in area by 77% since 1967, largely due to the effects of eutrophication, industrial development and sand mining. To answer a range of questions relevant to seagrass restoration, we (i) carried out a transplant trial, (ii) monitored the impact and recovery of the donor site, and (iii) retrospectively assessed genetic diversity in the transplant site.
Shark Bay stromatolites at risk from climate change
Climate change – resulting in more frequent flooding of the Wooramel River that leads into Shark Bay – may threaten the unique stromatolites that make Shark Bay a World Heritage site. These stromatolites – rocky structures formed over millennia by blue-green algae or cyanobacteria – thrive in Shark Bay’s Hamelin Pool, where an unusual undersea landscape has created an environment twice as saline as normal seawater.
