Gaarragoon Guardians- A Bardi Jawi Rangers’ Story Wins a Best Film Award at the 2021 Mud and Saltwater Film Fest

The Western Australian Marine Science Institution is proud to announce that its film collaboration with the Bardi Jawi Rangers and the Australian Institute of Marine Science has won a best film award at the 2021 Mud and Saltwater Short Film Fest.

The annual short film festival, held in Broome and Cygnet Bay, aims to inspire film makers to explore, respect, enjoy and protect remarkable Roebuck Bay and the Kimberley region. The festival showcases the best short films made by professional and amateur filmmakers about this truly remarkable part of the world.

Our short documentary film Gaarragoon Guardians: A Bardi Jawi Rangers’ Story, tells the story of two-way learning between scientists and the Bardi Jawi Rangers who have been monitoring the fish and coral reef to manage the health of sea country on the Dampier Peninsula.

This two-way learning started 10 years ago with the WAMSI Kimberley Marine Research Program (2012-2018) to develop an understanding of how fish, coral and seagrasses sustain the health of the Kimberley marine ecosystem.

When researchers from the Australian Institute of Marine Science returned to Country with some of the results, they found the rangers had a few questions of their own that they wanted answered.

A monitoring program was developed and what we have filmed is a field trip with the Bardi Jawi Rangers and the Australian Institute of Marine Science monitoring partnership in August 2020.

The rangers tell their story of working with scientists to monitor the health of their sea country.

To Bait or Not to Bait: Remote Underwater Video Surveys of Juvenile Fish

A new study comparing the efficiency of baited and unbaited remote underwater stereo-video to survey juvenile fish populations has found no significant difference between the two methods.

Juvenile fish are a particularly important group to monitor and understand given the high social, economic, and ecological value placed on adult fish populations.

Driven by their need for shelter from predators and environmental stressors, juvenile fish are often found in habitats which are difficult to sample other than by diver surveys. In the Kimberley however, diver surveys are impractical given the dangerous tidal conditions and the presence of crocodiles. Divers surveys have also been linked with a change in fish behaviour.

As part of the Western Australian Marine Science Institution’s (WAMSI) Kimberley Marine Research Program, a team of scientists from The University of Western Australia (UWA), The Australian Institute of Marine Science (AIMS) and the Kimberley Marine Research Station compared the use of baited and unbaited remote underwater stereo video systems (BRUVS and RUVS). The study took place in the Iwany (Sunday) Islands group with guidance from the Bardi Jawi Rangers and Traditional Owners.

Stereo-RUVS use two cameras on a frame that is lowered onto the seabed to record fish movement. The two cameras enable lengths and distance measurements to be made using specialised software.

Lead author UWA PhD candidate Camilla Piggott said the results, published in the Journal of Experimental Marine Biology and Ecology suggest both methods can effectively produce the same result.

‘’What we found was that there was no difference in the ability of stereo-BRUV or stereo-RUV to quantify the relative total abundance, species richness, or assemblage composition of juvenile fish,” Camilla said.

Sixty Stereo-RUVs and 60 Stereo-BRUVs samples were taken across four shallow-water (1-6 metre) coral, mangrove, macroalgae, and seagrass habitats to contrast the effect of the presence or absence of bait, deployment period, in-water visibility and tidally driven water speed.

“We found that a deployment period of 10 minutes for Stereo-BRUVs and 15 minutes for Stereo-RUVs was optimum for sampling the juvenile fish assemblage across all four contrasting habitats,” Camilla explained. “Since no statistical significance was observed between 10 and 15 minutes, we recommend that Stereo-RUVs deployed for 15 minutes during tidal slack water conditions are an optimum way to provide consistent results for comparisons of juvenile fish assemblages across the habitats studied in this region.”

Phytoplankton Proves its Carbon Capture Capability in Extreme Environments

A new study has found that phytoplankton, the microalgal powerhouse plants of the sea, are able to change their physiology and continue to uptake and store carbon despite the extreme tidal movement and dynamic light conditions in the Kimberley.

If there’s one thing that the Kimberley marine environment can teach us, it’s the best way to live in an extreme environment, according to CSIRO’s James McLaughlin, lead author of the latest paper on Phytoplankton Light Acclimation to Periodic Turbulent Mixing Along a Tidally Dominated Tropical Coastline published in JGR Oceans.    

The study in King Sound, which is a 100‐kilometre‐long, semi-enclosed embayment opening to the Indian Ocean, was conducted by researchers from CSIRO and The University of Western Australia as part of the Western Australian Marine Science Institution’s (WAMSI) Kimberley Marine Research Program.

It reveals that despite low nutrients and decreased water clarity in areas of the Sound, phytoplankton were able to photosynthesise as if it were in a high light exposure environment. On the adjacent shelf however, the roles reversed, phytoplankton migrate deeper and acclimatise their photosynthetic strategy to a lower light environment, enabling them to reach available nutrients at depth.

“King Sound experiences very large variations in light over short time scales, and we found that the phytoplankton community there was dominated by diatoms, a microalgae that can rapidly adjust pigment within the cell to acclimate to water column light conditions,” James McLaughlin said.

“What this does is allow higher maximum photosynthetic rates to be attained by the phytoplankton which are trying to live in a region with extreme tides, in an environment that is constantly changing from deeper turbid and dark waters to shallow more light exposed ones,” James said.

Tides help to redistribute phytoplankton and nutrients and this in turn influences their population and community structure within marine ecosystems. It is important to better understand the impact of tidal mixing on the ability of phytoplankton to capture and store atmospheric carbon dioxide in these dynamic coastal areas.

Kimberley Indigenous rangers and marine scientists met last week (Tuesday 1st – Thursday 3rd December 2020) at the annual Indigenous Saltwater Advisory Group (ISWAG) forum in Broome.

ISWAG is an Indigenous-led and facilitated saltwater forum for the Kimberley. It includes members from nine saltwater Prescribed Native Title Body Corporates (PBC’s); Balanggarra, Wunambal Gaambera, Dambimangari, Mayala, Bardi Jawi, Nyul Nyul, Yawuru, Karajarri and Nyangumarta, which represents traditional owner groups across 90% of the Kimberley coastline. ISWAG was created to support Kimberley saltwater managers to implement their Healthy Country Plans through collaborative research, policy and management.

Throughout the three-day forum, the group shared Indigenous knowledge and pair it with cutting edge science to enable best practice saltwater management to ensure the long-term sustainability of marine species in the Kimberley. The forum is recognised by scientists from state and federal agencies and institutions as a key advisory body about saltwater knowledge and management issues across the Kimberley.

A key outcome from the 2020 forum, was the tabling of an Indigenous led 10-year turtle and dugong management plan for the entire Kimberley region. The plan, funded by Parks Australia and the Department of Biodiversity, Conservation and Attractions (DBCA), lays out the framework for an integrated western and traditional research approach to all aspects of turtle and dugong management and conservation in the region. It builds on decades of foundational work done by Indigenous and non-Indigenous marine scientists and managers towards the long-term sustainability of dugong and turtle populations in north west Australia.

At the forum, western science partners from the Australian Institute of Marine Science (AIMS), DBCA, Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Department of Primary Industries and Regional Development (DPIRD) specialising in turtle, dugong, fish and saltwater habitats, co-presented the results of recent marine science projects.

The Western Australian Marine Science Institution (WAMSI) also presented preliminary findings from a review of the processes and protocols for scientists working on saltwater country developed with ISWAG.

Wunambal Gaambera Aboriginal Corporation (WGAC)

Desmond Williams, Uunguu Ranger, (WGAC), explains what they are doing on Wunambal Gaambera saltwater country to protect and monitor marine species.

We went out on our wundaagu (saltwater) in a small plane to look at the turtle tracks from flatback turtles and hawksbill turtles, and we share the results with this ISWAG group to get a better understanding of what turtles are doing across the whole Kimberley.”

We also did a survey of the marine threats such as fishing line debris, ghost nets and also look at where they are laying eggs and some of the threats, we have like dingoes eating the eggs on some of our islands.”

This group is really helpful. We need to build our skills to manage our wundaagu. We get to learn a lot from the other ranger groups and scientists. It is really good for us Wunambal Gaambera people to be sharing our knowledge on the same level as the other ranger groups in the Kimberley.”

For Wunambal Gaambera people, mangguru (marine turtles) and balguja (dugong) are important cultural foods especially for cultural gatherings.

We have hunted mangguru and balguja for generations and they are part of some people’s dreaming.

We know when a turtle is healthy by the shoulder fat. Our old people used to travel a long way by raft or canoe to outer islands to collect Amiya (turtle eggs) and survived on Amiya when they had no water.”

 

Nyamba Buru Yawuru (NBY)

Dean Mathews, Senior Project Officer, NBY, talks passionately about managing turtles and dugong on Yawuru Nagulagun Buru (Yawuru Sea Country) and why it is important to protect turtles on Yawuru country.

“If we are talking about the well-being of Roebuck Bay, protecting turtles and dugongs is very high on the priority for Yawuru people because of what those resources have provided for us for thousands of generations and we want to ensure the next generation have that to enjoy. It is a fundamental part of who we are,” explained Dean.

A lot of our turtles for example the green turtle, do not have nesting sites here.

Our rookeries (or nesting sites) are under a lot of pressure due to climate change, fishing, sea nets, plastics and hunting and so, as country managers we have to look at how the rookeries are sustaining them and what we need to do to look at the hunting aspects and frequency of take to protect our rookeries for future generations to enjoy.”

Working collaboratively, we are all accountable and we, the Traditional Owners who have lived on and interacted with turtles and dugongs for many generations, want to be a part of the higher-level conversation and policy at the Commonwealth level in regard to planning and managing these species. ISWAG provides this opportunity for a united voice from Kimberley Ranger groups.”

 

Bardi and Jawi Niimidiman Aboriginal Corporation

Kevin George, Senior Cultural Advisor, Bardi Jawi Rangers spoke about the value of coming together.

“We have a duty of care and obligations and one of the major reasons we come together is to protect cultural customs, traditions, livelihoods, the whole works.”

 

DBCA

Dr Scott Whiting, Principal Research Scientist, DBCA said:

“Collaborative work is extremely important for long term conservation, especially for long lived animals with complex life cycles like turtles and dugongs.

Each group of Traditional Owners, managers, scientists and policy makers bring different skills, knowledge and impact to conservation outcomes. Collaboration is the only way for long-term management.”

 

Western Australian Marine Science Institution (WAMSI)

Dr Kelly Waples, Kimberley Marine Research Program Science Coordinator, (WAMSI), presented preliminary findings from a review of the process and protocols for scientists working on saltwater country developed with ISWAG.

The review is based on surveys with researchers, Healthy Country managers, Indigenous organisational staff, Traditional Owners and government staff who have worked through the steps outlined in the Collaborative research on Kimberley Saltwater Country – Guide for Researchers.

“The Kimberley is leading the way in encouraging western scientists to consider how they can collaborate with Indigenous rangers to address important outcomes for Healthy Country Plans,” Dr Waples said.

“This review will give ISWAG a better idea of how the process is working for the saltwater groups, researchers and government agencies so that ISWAG can consider any improvements that could lead to better results for the Kimberley.”

Our Knowledge Our Way Indigenous-led guidelines

This article was originally published on an archived WAMSI website. Some media or links may appear missing or broken. You can use the search function to look for these, or contact info@wamsi.org.au for a specific request.

The ‘Our Knowledge Our Way in caring for Country – Best Practice Guidelines from Australian experiences’ is based on 23 case studies from across Australia, including the Western Australian Marine Science Institution’s Kimberley Indigenous Saltwater Science Project.

The North Australian Indigenous Land and Sea Management Alliance Ltd (NAILSMA), CSIRO, and the Australian Committee for IUCN facilitated the guidelines as part of NESP Northern Australia Environmental Resources Hub research that is supporting Traditional Owners by enabling the sharing of their knowledge the ‘right way’ in land and sea management and environmental research.

“These guidelines better value and strengthen Indigenous knowledge holders and the systems that need to be in place to protect Traditional knowledge, in a platform that can be readily accessed by the researchers and the broader community,” said Ricky Archer, CEO of NAILSMA and Djungan man from the Western Tablelands of north Queensland. “One of the best examples that mixes cultural knowledge systems and Western knowledge frameworks is Savanna Burning Projects, a cultural burning practice that’s been put through an academic framework to measure things like carbon.”

Through the Indigenous-led guidelines, the authors share what is seen as best practice when working with Indigenous knowledge in land and sea management, research and enterprise development.

Weaving Indigenous knowledge and science:
the KISSP approach. Case Study 3 -9

Figure 3.6. The concept of weaving knowledge systems (above)
and the Multiple Evidence Base approach (below).

The guidelines highlight how Indigenous knowledge is kept strong through access to Country and Indigenous cultural governance of knowledge. The key guiding principle is that Indigenous people must decide what is best practice in working with Indigenous knowledge. The guidelines cut across four themes: strengthening Indigenous knowledge; strong partnerships; sharing and weaving knowledge; and Indigenous land and sea networks.

“We need to take the time to listen and show respect for Aboriginal and Torres Strait Islander Peoples’ knowledge, culture and Country, and be led by their knowledge,” said Dr Emma Woodward, research scientist at Australia’s national science agency CSIRO. “We have much to learn from Indigenous Peoples and so much more to achieve by working together.”

Executive member of the Australian Committee for IUCN and IUCN Regional Councillor Peter Cochran said: “The Committee’s support for this publication reflects our acknowledgement and respect for Australia’s long and rich history of land and sea management by Indigenous Peoples, and their deep knowledge and expertise about a vast and changing continent.”

The guidelines identify ways that partners can support good knowledge practice, for example, through strong partnership agreements, support for cultural governance arrangements, and protocols.

The case study “Yanama budyari gumada: walking with good spirit at Yarramundi, western Sydney” shows how partnerships work where there is trust founded on mutual respect. The Darug custodians explain how they are facilitating important connections with other people who connect with Yarramundi, helping them to “sign-in” to Country. They show visitors how to crush up white ochre and blow it out of their mouths to put a handprint on the casuarina trees.

The Indigenous-majority project Steering Group hope the guidelines prove useful to assist sharing and learning between Indigenous land and sea managers, to educate current and future partners, and to realise good outcomes for people and Country.

The guidelines and a film showcasing the work can be found at Our Knowledge Our Way.

Warming and Higher Rainfall Could Be a Recipe for Phytoplankton Success

This article was originally published on an archived WAMSI website. Some media or links may appear missing or broken. You can use the search function to look for these, or contact info@wamsi.org.au for a specific request.

Historical records from seabed sediment cores have revealed that the warming climate and increased rainfall in Australia’s North West could in fact be creating ideal conditions for the increased production of phytoplankton, one of nature’s most important indicators of ocean health.

The findings from the study: Phytoplankton Responses to Climate‐Induced Warming and Interdecadal Oscillation in North‐Western Australia, published in the journal Paleoceanography and Paleoclimatology, are the first to confirm these patterns.

The sediment cores were collected as part of the Western Australian Marine Science Institution’s Kimberley Marine Research Program from three bays along the Kimberley coastline, including Roebuck Bay off Broome, Koolama Bay off King George River, and Cygnet Bay in King Sound.

 

Above: Sediment cores were collected from 3 bays – Roebuck Bay off Broome, Koolama Bay off King George River, and Cygnet Bay in King Sound.  

 

Lead researcher Dr John Keesing from CSIRO’s Ocean and Atmosphere said the results were surprising given that warming of the ocean had been forecast to reduce phytoplankton productivity in tropical/subtropical oceans, through increasing stratification of the water column, locking deep-water nutrients away from productive surface layers, and through temperatures exceeding the thermal tolerance of some phytoplankton species.

“What we found is that up to three times more phytoplankton biomass has been produced since the 1950s along a large section of the Kimberley coast,” Dr Keesing said. “The majority of that can be linked with climate change induced increases in sea surface temperature, strong tidal mixing of coastal waters and increased rainfall creating improved nutrient supply conditions, feeding phytoplankton growth and production in shallow coastal waters.”

The study also found that 20.4 per cent of the variation in phytoplankton biomass was related to long-term changes in the Interdecadal Pacific Oscillation (IPO) which has an important influence on coastal nutrient supply. The positive, or warm phase of the IPO, is associated with a weaker Indonesian Through Flow (ITF) current , which enhances upwelling, a process which brings nutrients from deep water to shallow coastal waters. The present, negative or cool phase of the IPO has the opposite effect, with a strong ITF suppressing upwelling and restricting nutrient supply from the deep ocean.

“We predict that the negative impact of rising temperatures on phytoplankton in northwestern Australia could be buffered by increasing rainfall, perhaps associated with more tropical cyclones, evolutionary adaptation of local phytoplankton species to warm conditions and the upcoming warm phase of Interdecadal Pacific Oscillation,” Dr Keesing said.

Encrusting sponge found in Kimberley coral reefs

This article was originally published on an archived WAMSI website. Some media or links may appear missing or broken. You can use the search function to look for these, or contact info@wamsi.org.au for a specific request.

The coral-killing sponge Terpios hoshinota has been detected in the Kimberley for the first time by scientists from the Western Australian Museum.

Terpios hoshinota is commonly referred to as ‘black disease’ because of its colour and because it overgrows both live and dead coral. It has been reported in many areas of the Indo-Pacific, including the Great Barrier Reef, but has not previously been found in Western Australian waters.

The sponge was detected during fieldwork in 2016 by the WA Museum’s Dr Jane Fromont, Dr Zoe Richards and Dr Nerida Wilson, with assistance from the Wunambal Gaambera Aboriginal Corporation and the Uunguu Rangers. Their research has now been published on open access scientific journal platform MDPI.

Dr Fromont said the Kimberley region of the State has some of the least impacted coral reefs globally.

“We report for the first time the presence of Terpios hoshinota in the eastern Indian Ocean on Kimberley inshore coral reefs,” Dr Fromont said.

“It is important to note that while there has been no outbreak event by Terpios hoshinota in the Kimberley, our observations of its presence suggest monitoring may be required to reduce the possibility of it spreading undetected. Terpios hoshinota is visually striking, and we encourage regional management authorities to include it in their reef health surveys.”

Dr Fromont said while the causes of Terpios hoshinota overgrowing corals remain unclear, the ability of the species to spread over coral reefs and cause coral death is concerning.

Where possible, small fragments of gray-black coral-encrusting sponge should be collected for expert identification at the WA Museum.

Promoting collaborative and respectful partnerships for Sea Country research in WA

Some 60 Indigenous and marine science participants at the Australian Marine Sciences Association (AMSA) Indigenous Workshop held in Fremantle in July this year identified the Kimberley saltwater science guidelines as a potential blueprint for regionalising processes and protocols for research.

The fourth annual Indigenous workshop convened under a partnership between the NESP Marine Biodiversity Hub and the AMSA brought together a representative group to discuss a way forward on developing better ways of working together on sea country.

The WAMSI Kimberley Indigenous Saltwater Science Project (KISSP), which subsequently led to the development of the Indigenous Saltwater Advisory Group (ISWAG), has been recognised for its success in establishing a pathway for right-way research.

CEO Luke Twomey said the WAMSI science partnership was happy to support the rollout of the KISSP process and is already working with regions where WAMSI is developing science plans.

“We have just completed a three-day workshop with the Malgana people in Gathaagudu (Shark Bay) where the key objective was to understand the science priorities for the Malgana people so their voices could be incorporated into the Shark Bay Science Plan process,” Dr Twomey said. “Part of that process is providing the Traditional Owners with an understanding of what science has already been done on Country, who the science  organisations are and what guidelines have been developed elsewhere. From there the Aboriginal Corporations can develop their own processes and protocols for working with scientists on Country.”

The 2019 AMSA Indigenous Workshop Summary Report is available here.
