Advanced online tool designed to monitor and track the condition of coastal mangrove ecosystems over time. Using aerial imagery and real-time data, this tool provides insights into mangrove health, environmental changes, and conservation efforts. Easily accessible and user-friendly, it empowers researchers, conservationists, and the public to take action in protecting vital coastal habitats. Coastal health tracker What is it? We have undertaken coastline aerial surveys across northern Australia since 2009, collecting valuable, systematic, geo-referenced imagery for documenting changes occurring within shoreline ecosystems These surveys have captured thousands of high-resolution images covering around 16,000 km of shoreline, enabling us to create a web platform that showcases these aerial images. This online tool provides views of shoreline vegetation, topography, and changes through time, allowing users to monitor and evaluate changing shoreline conditions. An imagery tool for tracking coastline changes over time Our team has conducted aerial surveys across northern Australia, capturing high-resolution, overlapping images of shoreline vegetation using small helicopters. These surveys have already captured thousands of images spanning 16,000 km of shoreline from 2009 to now. This online tool makes coastal imagery datasets easily accessible, allowing users to view and inspect shoreline sites of interest and to evaluate current vegetation condition and the types of changes taking place. As we continue to monitor Australia’s shorelines, new imagery will be uploaded to this tool as it becomes available. Snapshots of coastal vegetation health Aerial surveys have been undertaken to identify major drivers of change in shoreline mangrove and tidal saltmarsh environments. Habitat condition is recorded during or after these surveys, using visual indicators of health and disturbance developed by Professor Duke. These surveys have been funded from multiple sources to assess a range of incidents including: Severe cyclone and flood damage. Rising sea levels. Restoration hotspots. Large-scale pollution events. Coastal development pressures. Monitoring assessments are crucial for effective, informed management of valuable and beneficial coastal habitats, which are increasingly threatened by a range of human- and climate-driven stressors. How this online tool can be used This online tool has been developed by our team to display high resolution, low-level, oblique aerial imagery of shoreline ecosystems like mangroves, tidal saltmarsh, coastal dunes, and sandy beaches. The tool can be used for shoreline condition monitoring, restoration project assessments, storm and flood incident evaluations, and general annual reporting on shoreline ecosystem condition. Project details The aerial surveys that produced these imagery datasets were led by Professor Norman Duke and Dr Adam Canning. Survey projects were funded by various sources including Greening Australia, the Australian Government, the National Environmental Science Program, PTTEP Australasia, and the Queensland Government’s SmartState Program.

We are partnering with communities to understand species distribution and detect invasive species using environmental DNA (eDNA). Torres Strait, Townsville, Burdekin catchment Location Targeted monitoring of native and invasive species is challenging in remote northern Australian environments, but community partnerships and eDNA approaches are increasing opportunities for monitoring programs. We are partnering with communities to assess biodiversity and detect invasive species in northern Australian waterways using environmental DNA (eDNA). These projects are strengthening local knowledge, improving long-term data collection, and creating shared ownership in the protection of northern Australian ecosystems. Key points Community-led ecological monitoring using eDNA BACK Shifting approaches to monitoring Traditional methods for ecological monitoring are expensive, labour-intensive, and require specialist training, making them poorly suited to community involvement and use in remote areas of northern Australia. This creates challenges for monitoring the spread of endangered native species for conservation as well as invasive species that pose a risk to biosecurity. Newer techniques such as environmental DNA ( eDNA ) are expanding possibilities for ecological monitoring in the region and creating opportunities for communities to take the lead – with significant benefits for northern Australian biodiversity and biosecurity. Harnessing eDNA for community-powered monitoring We are working with local communities on a range of projects using eDNA methods to gain insights into species distribution across northern Queensland, including invasive and endangered species. Using our simple and cost-effective eDNA sampling kits , community partners and volunteers can easily collect water samples for analysis in our eDNA laboratory. Working with communities significantly increases the geographical spread and number of samples than can be collected, expanding our capacity for targeted ecological monitoring and improving long-term data collection. Supporting community-led monitoring efforts also builds local knowledge and capacity and creates shared ownership in the protection of biodiversity in northern Australia. Fish assemblages in tropical waterways We are developing an eDNA metabarcoding technique to comprehensively assess fish assemblages in tropical waterways. eDNA metabarcoding identifies multiple species from a single water sample, providing a community-level snapshot of fish species to help us understand ecosystem health and potential threats to fish biodiversity in these waterways. Water samples are collected by OzFish Unlimited and Townsville City Council volunteers through the CreekWatch citizen science initiative for analysis in our eDNA laboratory. This project will provide a more complete picture of fish assemblages in our tropical waterways, informing waterway management. Invasive ants across Great Barrier Reef islands We are partnering with local communities to improve monitoring for four species of invasive ants across high-risk islands of the Great Barrier Reef using eDNA. Samples are collected in the field by Indigenous Rangers, citizen scientists, and tourism operators. Our researchers then extract DNA from these samples to detect yellow crazy ants, electric ants, red important fire ants, and tropical fire ants. These invasive ants pose a serious threat to native wildlife on islands of the Great Barrier Reef. By monitoring for these four invasive ant species, this project will identify early incursions and potential changes in abundance over time. Results will inform future efforts to prevent incursions of invasive ants, with detection potentially triggering targeted eradication programs. Cane toads in Torres Strait We are working with Torres Strait Regional Authority (TSRA) Rangers on the early detection of cane toads in freshwater bodies in Torres Strait. Cane toads are a problematic invasive species across Queensland – poisoning predators and outcompeting native animals. The outer islands of Torres Strait remain among the few cane-toad-free places in Queensland. Cane toads need water contact every day to hydrate, allowing our researchers to detect their DNA in the sampled water even if only a single toad is present. TSRA Rangers are using our specialised eDNA kits to collect water samples that are then analysed in our eDNA laboratory to detect any genetic traces of cane toads. Monitoring programs like this one provide a practical tool for early detection of invasive species to support local biosecurity efforts. Project details These projects are led by Dr Cecilia Villacorta-Rath, and include partnerships with OzFish Unlimited, Townsville City Council, the Queensland Government Department of Environment, Tourism, Science, and Innovation, the Great Barrier Reef Foundation, and Torres Strait Regional Authority and funding from the National Environmental Science Program.

Seagrass is a marine plant – and it is the only flowering plant that can live under ocean waters. There are four major groups of seagrasses divided into around 60 to 70 species. Seagrass can sometimes be mistaken for seaweed, which is algae that does not have a true root system and reproduces via spores. TropWATER Explainer: Seagrass 12 May 2025 TropWATER BACK What is seagrass? Seagrass is found in intertidal (exposed at low tide) and subtidal (constantly submerged) habitats around most continents of the world, and around many reefs and islands. The Great Barrier Reef Marine Park is home to one of the largest seagrass ecosystems worldwide. Why is seagrass important? Seagrass meadows provide a range of valuable and interconnected ecosystem services, including: Food for marine animals and shorebirds – seagrass is the main food source for dugongs and sea turtles, and shorebirds can forage for food in coastal meadows. Carbon capture and storage – by efficiently capturing and storing carbon, seagrass meadows help to reduce levels of carbon dioxide in the atmosphere. Nursery habitats – seagrasses support important fisheries by providing sheltered habitats for young marine animals. Coastal protection – the roots and rhizomes of seagrass hold sediment in place, reducing erosion, and some seagrass meadows can reduce wave energy. Water filtration – by filtering out nutrients and trapping fine sediments from the water, seagrasses improve water clarity and are likely to protect corals from disease. The health of seagrass meadows – and the ecosystem services they provide – are threatened by several direct and indirect factors such as heat stress, runoff from land, human activities, and severe storms. Our work with seagrass As one of Australia’s largest tropical seagrass research groups, we lead a range of seagrass projects across northern Australia that include: Mapping – we work with Traditional Owner groups across northern Australia to map where seagrass meadows can be found. Long-term monitoring – we work with Traditional Owners and industry across the Great Barrier Reef coastline, Torres Strait, and Gulf of Carpentaria to monitor seagrass in the same areas each year. Long-term monitoring allows us to understand how meadows are changing and identify when scientific advice to management is needed. Restoration – we are trialling methods to restore seagrass in areas where meadows have been damaged or lost, such as Mourilyan Harbour.

A flood plume – also known as a river plume – is a large volume of freshwater discharged from a river into the ocean, caused by heavy rainfall and flooding. Plumes can carry sediment, nutrients, pesticides and other contaminants from the land into coastal and marine waters. TropWATER Explainer: Flood plumes 17 August 2025 TropWATER BACK How far the flood plume spreads depends on factors such as the volume of water discharged, wind and currents, and how long the flooding lasts. How do flood plumes affect marine ecosystems? Sediment and nutrients transported by flood plumes can have significant negative impacts on the health of inshore seagrass meadows and coral reefs by: Reducing light – sediments suspended in water can limit the available light for plants to grow. Smothering – silt and mud can cover seagrass and coral. Increasing nutrients – higher nutrient levels can stimulate macroalgal growth, which can eventually outcompete corals and can cause coral disease and increased bioerosion. Coastal and inshore areas are the most likely to be affected by flood plumes as they are located closer to the source of the plume, although larger plumes can carry suspended sediment and nutrients to mid and outer reefs. There is a lot of evidence about the impacts of flood plumes on inshore areas but less it known about impacts further offshore. The severity of these impacts depends on the timing and size of the flood plume, the amount of sediments and nutrients carried by them, the health of the ecosystems prior to exposure to the plume, and whether other disturbances occur at the same time (such as cyclones or high temperatures). Our work monitoring flood plumes Our researchers have been studying how river runoff and flood plumes move within the Great Barrier Reef for over two decades. We also work with landholders and agricultural professionals to provide science-based solutions for improved farm management practices to reduce fertiliser and pesticide losses and manage soil erosion. Our work includes: Sampling flood plumes from major rivers across the Great Barrier Reef catchments. Developing techniques to assess water quality remotely using satellite imagery. Fine-scale monitoring of sediment and nutrient sources on agricultural lands, in collaboration with landholders. Developing models to predict pollutant pathways and identify pollutant ‘hotspots’ for targeted management.

Coral recruitment is the process where coral larvae settle onto reef surfaces, survive early stages, and grow into new colonies, supporting reef recovery, resilience, and long-term ecosystem health after disturbance. TropWATER Explainer: Coral recruitment 13 May 2025 TropWATER BACK How do corals reproduce? Corals reproduce in two main ways: spawning and brooding. Spawning corals release bundles of eggs and sperm into the water, where fertilisation occurs. The resulting embryos develop into larvae that drift for days to weeks before settling onto reef or rubble and forming a hard skeleton as they grow into young coral colonies. Brooding corals fertilise eggs internally within the parent colony. Sperm released by nearby colonies is ingested through the polyp’s mouth, and the parent then releases mature larvae, which typically settle close to their origin. What is coral recruitment? Coral recruitment refers to the process where coral larvae settle onto a surface, survive, and grow for the first 8-12 weeks of their lives. Coral reefs worldwide face increasing threats including heatwaves and mass bleaching, cyclones, flood plumes, and outbreaks of coral-eating Crown-of-Thorns starfish. Under such pressures, successful coral recruitment is more crucial than ever for reef recovery. How do we measure coral recruitment? Newly settled corals are microscopic, making them nearly impossible to see directly on the reef. Scientists use artificial surfaces – settlement tiles or plates – that mimic the reef that can be removed two to three months after spawning for examination under a microscope in the lab. Counting coral recruits on the tiles provides an estimate of the average density of recruits at a given reef site. How are our scientists studying and boosting coral recruitment? Our researchers are leading a collaborative study with tourism operators, Indigenous Rangers, NGOs, and other community volunteers to track long-term coral recruitment trends in the Cairns and Port Douglas region using settlement tiles. This is helping to fill critical knowledge gaps in how reefs in the region are faring under increasing pressures and will inform managers and decision makers aiming to enhance early stages of reef recovery. The team has also been part of collaborative efforts to harness spawn in laboratory settings and floating nurseries on the reef to generate millions of coral larvae for settlement – this is called coral seeding. Recent work has focused on settling larvae on artificial settlement devices in the lab, protecting young coral recruits from herbivores and other threats during their most vulnerable early weeks before being deployed to reefs in need. Ongoing research is critical to understanding long-term survivorship of coral recruits through various coral seeding techniques – and to determine whether boosting the number of coral recruits results in more adult colonies contributing to reef health and recovery.

What is a nursery habitat? A nursery habitat is an ecosystem that supports juveniles of marine species. They are often coastal ecosystems such as seagrass meadows, mangroves, and saltmarshes that offer three-dimensional structures compared to flat areas of mud or sand. TropWATER Explainer: Nursery habitats 12 May 2025 TropWATER BACK What is a nursery habitat? A nursery habitat is an ecosystem that supports juveniles of marine species. They are often coastal ecosystems such as seagrass meadows, mangroves, and saltmarshes that offer three-dimensional structures compared to flat areas of mud or sand. Different species may need different things from their nursery habitats – this includes a range of factors such as protection, food, proximity to other habitat types, and levels of competition or predation. After growing up in a nursery habitat, many adults will migrate to other types of habitats – this is called ontogenetic movement. A habitat is not considered a nursery for a particular species if that species exclusively uses that habitat throughout its life. Why are nursery habitats important? Nursery habitats support juvenile abundance, growth, and survival – this is critical to maintain healthy adult populations. These populations include many species of commercial, recreational, and cultural importance. Nursery habitats are part of interconnected networks of habitats supporting species across all stages of life. As nursery habitats are often found in coastal ecosystems, they can be at high risk of damage or loss due to coastal development and natural disturbances. Identification and monitoring of nursery habitats can inform development planning to conserve these valuable ecosystems. How are we studying nursery habitats? Our researchers are identifying the types of fish present in different coastal habitats – as well as their size and abundance – to understand how different fish and invertebrate populations use nursery habitats across the Great Barrier Reef region. This includes: Surveying inshore habitats between Mourilyan and Magnetic Island with Traditional Owners and Rangers to identify nursery habitats. Monitoring the long-term abundance, size, and diversity of fish species on coral reefs at inshore islands in the Great Barrier Reef Marine Park. Mapping habitats in reef lagoons in the Coral Sea Marine Park to identify the fish species present and which habitats they prefer. Monitoring fish and invertebrates in disturbed and recovered seagrass meadows to compare nursery function. Related projects Monitoring fish communities in nursery seascapes Next Previous

Environmental DNA (eDNA) research plays a vital role in for detecting and monitoring invasive species for biosecurity management. Australia Location eDNA is a fast, cost-effective alternative to traditional methods. It improves biosecurity by detecting low-density and hidden species over large areas. Our eDNA technology allows early detection of invasive species, like yellow crazy ants and Varroa mites. It enables rapid biosecurity response and management to stop their spread. We involve Indigenous Rangers, citizen scientists, and stakeholders in biosecurity monitoring programs. This improves surveillance and reporting accuracy. Key points eDNA technology revolutionises invasive species biosecurity BACK Challenges detecting and managing invasive species Invasive species are a serious threat to ecosystems, native species, and agricultural systems, leading to substantial economic and environmental damage. Early detection and management of invasive species are critical for effective biosecurity measures. Traditional monitoring methods, such as visual surveys, trapping or netting, have many limitations. They can be time-consuming, labour-intensive, require considerable training/experience and cannot detect species over large areas. It can also be difficult to detect low-density, rare species or small cryptic species. These limitations can cause delays in detecting invasive species, allowing them to establish and spread before effective management actions can be implemented. Using environmental DNA technology as an alternative method can fast-track detection and improve biosecurity management efforts. How our eDNA technology is detecting invasive species Environmental DNA (eDNA ) research plays a vital role in for detecting and monitoring invasive species for biosecurity management. Our team are leading efforts to combat invasive species through advancing environmental DNA (eDNA) research, providing a cost-effective and rapid method that can cover large areas. By analysing DNA fragments shed into the environment by a target species, we can detect invasive species early, even before signs of infestation become apparent. Detecting Yellow crazy ants Yellow crazy ants are considered one of the world’s most invasive species, with outbreaks found in Queensland, and more broadly in Australia and the Indo-Pacific. Left untreated, the acid-spraying and voracious ants can increase in density to consist of millions of workers, with a detrimental impact on native fauna. Our eDNA research has developed a world-first environmental DNA (eDNA) method that can detect infestations. of this terrestrial invertebrate from water samples in adjacent waterbodies. We tested and validated eDNA technology in the field, detecting yellow crazy ants even at low populations. We are working towards determining how can eDNA sampling be used for timely identification of yellow crazy ants incursions, enabling rapid response and control measures to prevent further spread. Invasive ants across Great Barrier Reef Islands We are improving monitoring capacity for targeted invasive ants across high-risk islands of the Great Barrier Reef. This includes yellow crazy ants, electric ants, red imported fire ants, tropical fire ants. Our eDNA monitoring of these invasive ant species is detecting early incursions. We are training Indigenous Rangers, citizen scientists, tour operators, and community members to take part in monitoring programs. Our research is utilising rapid detection of target species to prompt eradication efforts, thereby mitigating their impact on native biodiversity. The data generated by the project is prioritising future prevention efforts. Screening of Varroa mites using eDNA technology This project tests the application of environmental DNA (eDNA) methods for invasive honeybee Varroa mites. Utilising eDNA methods, we have established reliable protocols for detecting Varroa mites in honeybee populations. Our research has contributed to the development of portable diagnostic technology, allowing for on-site screening of bees and swift identification of Varroa mite infestations. The application of eDNA technology has enhanced biosecurity measures in beekeeping operations, facilitating early intervention to manage Varroa mite outbreaks. How eDNA research is revolutionising biosecurity Our eDNA research has significantly transformed biosecurity efforts by enabling early detection and effective management of invasive species. This technology enhances biosecurity surveillance through: Developing and implementing robust eDNA methods for detecting priority invasive species such as ants and Varroa mites. Using state-of-the-art lab analysis and portable sequencing devices for rapid, precise screening. Engaging Indigenous Rangers, citizen scientists, and stakeholders in community-based monitoring programs. Collaborating with stakeholders and research partners to streamline field applications and optimise data collection. Supporting proactive conservation and management strategies for swift responses to invasive species incursions.

We are using environmental DNA to understand the distribution of fish species, allowing us to identify structures that act as barriers to fish migration. Northern Australia Location Structures like culverts, weirs, causeways, and tidal gates are common barriers that prevent fish from migrating between freshwater and marine habitats, leading to a decline in fish diversity. Our researchers are using environmental DNA (eDNA) technology to understand the distribution of various fish species in northern Australia, identifying which structures act as barriers to fish migration. This research is helps decision-makers determine how to manage these barriers, whether by removing them or implementing measures to facilitate fish migration. Key points Using eDNA to detect barriers to fish in Australian waterways BACK How fish barriers impact Australian native species Human-made physical barriers like culverts, weirs, causeways and tidal gates are common fish barriers, stopping fish from migrating between freshwater and marine habitats. This loss of connectivity is contributing to a decline in fish diversity. Many Australian fish species need to move between marine and freshwater habitats at different times of the year to feed, reproduce, spawn, access nursery grounds and escape predators. Barramundi in particular struggle with barriers, limiting their ability access essential habitats. In extreme cases, barriers like large weirs and dams can lead to localised extinctions. Thousands of barriers exist in coastal areas, making it critical to understand their effects on fish communities. Determining the fish communities that have been able to make it past these barriers is key to understanding their effects on Australian native fish. Identifying fish barriers with eDNA TropWATER scientists are using eDNA technology to revolutionise how we identify problematic fish barriers in Australian waterways. The technology uses water samples to detect genetic material left in the water, such as mucus, scales, and other residues, without capturing or sighting the species. These methods help scientists quickly see if key fish, such as barramundi, can migrate past these barriers, and if it's harming fish diversity. This is pinpointing which structures block fish passage for fish migration and survival, providing critical data to support better management. Detecting fish species upstream from such structures using eDNA methods could give an idea of whether these are impeding fish migration. Monitoring and management With eDNA technology, managers can make informed decisions about barrier removal or modification, ensuring better connectivity for fish populations. eDNA methods allow for more accurate environmental impact assessments by providing precise data on fish presence and migration patterns. This data helps organisations and environmental managers who need to identify problematic barriers and develop strategies to mitigate their impacts. This approach not only enhances fish diversity but also supports the sustainability of freshwater and marine ecosystems in northern Australia.

We are using eDNA to detect the presence of invasive fish in waterways. Queensland, New South Wales Location Invasive species such as introduced tilapia are out-competing native Australian fish, particularly in the tropics. Environmental DNA (eDNA) is an important tool for detecting and understanding the distribution of invasive fish in Australian waters. We have developed a highly reliable assay for detecting tilapia and are working to detect other potentially problematic species. Key points Using eDNA as a surveillance tool for invasive fish BACK Invasive fish species displacing Australian native fish Invasive fish species are a major problem in Australian waterways. This is especially true in the tropics, where tropical species from the aquarium trade thrive in the warm water. Spotted Tilapia (Tilapia mariae ) and Mozambique Tilapia (Oreochromis mossambicus ) were introduced as aquarium fish and are considered the most problematic invasive fish in Queensland. Tilapia are out-competing and displacing native Australian fish through efficient breeding strategies, aggressive behaviour, and flexibility around habitat, diet, temperature, salinity, and oxygen levels. Tilapia are now present in 21 of 76 catchments in Queensland. Detecting and understanding new invasive species is key, and vital for effective management. But, collecting this data across catchments is challenging. Environmental DNA (eDNA ) is a promising tool for detecting these species in our waterways. Using eDNA to track invasive fish in Australian waterways Our team are using eDNA to detect the presence of invasive fish in waterways. This technology allows us to determine their distribution, map high-risk areas, and then target these areas for routine surveillance. eDNA technology detects genetic material left in waterways, such as mucus, scales, and other residues. We collect water samples and analyse them in our laboratory for the gene sequences of the fish species present. The eDNA assays developed at TropWATER have a high reliability of detection. They have been used to understand the distribution of tilapia in the Mitchell, Townsville, Fitzroy, Pioneer, Wild, and Walsh catchments in Queensland, as well as a recent incursion in northern New South Wales, and undertaking invasive fish monitoring in the Murray-Darling catchment and northern islands of the Torres Strait. Scientists have also developed eDNA primers for two potentially problematic invasive species: the climbing perch (Anabas testudineus ) and snakeheads (Channa striata ). The team are using these primers to detect early incursions into northern islands of the Torres Strait. Another species of biosecurity concern is sleepy cod (Oxyeleotris lineolatus ), which despite being endemic to north Queensland, has spread outside of its natural range and can have negative impacts on new ecosystems. The team has developed a primer targeting this species and is using it to detect incursions in the Georgina-Diamantina catchment. To stop the further spread of invasive fish species to new catchments, it is critical to detect new populations early. Using eDNA techniques will play a key role in this. eDNA techniques for effective invasive species management The ongoing work at TropWATER is crucial for bridging the gap between scientific research and practical management actions. By continuing to refine our eDNA methods and expanding our monitoring efforts, we aim to provide science-based solutions that support effective management strategies. This approach helps managers make informed decisions on where to allocate resources and implement control measures, preserving native fish and keeps Australia's water healthy.

We are using DNA methods to identify what dugongs in the Townsville region are eating other than seagrass, and trialling a new eDNA approach. Townsville Location Dugongs feed primarily on seagrass, but it is not known whether dugongs actively seek out or avoid any species that live within seagrass meadows like, sea cucumbers, sea squirts, sponges. This project will analyse dugong poo using DNA methods to identify what dugongs are eating other than seagrass. This will give us clues about what makes a seagrass habitat most beneficial for them. It will also assess eDNA methods on poo faeces collected to accurately determine if it came from a dugong or turtle. This has the potential to help communities identify if the marine mammals are present in the area, especially in regions where populations have significantly declined or hard to find. Key points Assessing dugong poo using eDNA BACK Eating habits of dugongs Dugongs feed primarily on seagrass . They also incidentally consume species found living in seagrass such as sea cucumbers, soft corals, and sea squirts. However, little is known about whether dugongs actively seek out or avoid any of the species found in seagrass habitats, especially when seagrass is scarce. Knowing more about dugong feeding behaviours, including what marine species they prefer to eat, could improve our understanding of which seagrass meadows best support this iconic megafauna. DNA traces provide a unique way to determine what dugongs are eating. Finding clues in poo This project is breaking new ground by using non-intrusive eDNA methods to analyse dugong poo, offering detailed insights into their diets. Our researchers will collect and analyse up to 20 samples during surveys across 350 square kilometres of seagrass meadows in the Townsville region. The team will then use two DNA analysis methods on these samples to detect what marine species dugongs are consuming: Mini eDNA kits will be used to determine whether the sample is dugong or turtle poo, and the presence or absence of marine species. As these kits were designed for water sampling, samples will be suspended in distilled water for analysis. Conventional DNA analysis will confirm whether the sample is dugong or turtle poo and provide more detailed results on presence of DNA of other species in the sample. This work is connected a broader project by our researchers assessing seagrass habitats in the Townsville region. Our researchers will compare all DNA results with species recorded during the seagrass surveys. How these insights progress dugong conservation Determining what species dugongs are consuming will reveal if dugongs have specific food preferences or if they eat any available seagrass and any species living within these meadows. The presence of species not recorded locally – including types of seagrass as well as sea cucumbers, sponges, and other animals living among seagrass –may also suggest the Townsville dugong population is traveling farther, possibly to find food. This will expand our understanding of dugong behaviour and help assess the ability of seagrass meadows to support their preferred foods. The research will help protect vital seagrass habitats and support conservation efforts for endangered dugong populations globally. Researchers will also compare mini eDNA kits with conventional DNA analysis to see if these kits can be used to reliably study marine megafauna feeding habits. If successful, mini eDNA kits could offer an affordable, accessible way to study dugong feeding behaviour in other regions with endangered populations. This project can answer key questions without disturbing these endangered animals.

From sampling methods to laboratory analysis, we are advancing eDNA science to solve environmental challenges more effectively and enable communities to engage in monitoring using eDNA. Northern Australia Location Environmental DNA (eDNA) is transforming how we detect plants and animals in the environment – without even sighting the target species. Refining and advancing these methods is necessary to maximise their usefulness. We are advancing eDNA science by improving how samples are collected in the field and how they are analysed in our lab, with a focus on developing methods for northern Australia’s unique environments. These advances are helping solve environmental challenges more effectively and opening more opportunities for communities to take part in environmental monitoring. Key points Advancing eDNA science BACK Unlocking the potential of eDNA Environmental DNA (eDNA ) detects species using the tiny genetic traces left behind in water or soil. This approach offers major advantages over traditional ecological monitoring, which is often costly and requires seeing or capturing species and spending long hours in the field. But eDNA methods are still evolving. Many techniques have been designed specifically for cooler climates, and sample collection requires specialised training. We are dedicated to improving the way we use eDNA to reach the full potential of this technique. From sampling through to analysis We are continuously developing the methods we use to collect eDNA samples in the field and analyse them in our laboratory. Our team specialises in improving how samples are collected and preserved to make eDNA techniques feasible in hot and remote environments. Improving sample collection Our team has made eDNA sampling easier so communities and citizen scientists can collect water samples with minimal training. Existing sampling methods require large volumes of water to be collected, filtered, and refrigerated before being analysed. Our method uses small tubes – or larger jars for sampling rivers and lakes – containing a preservative. These samples are less vulnerable to contamination and do not need to be refrigerated, making this method suitable to use in the tropics. We have created user-friendly eDNA sampling kits using our simplified method and distributed these to community partners and Indigenous Ranger groups. These kits enable easy sample collection in remote locations across northern Australia, creating opportunities for citizen science programs and community-led monitoring to use eDNA. Developing assays for northern Australia We have developed a range of specific tests (assays) for species of management concern in northern Australia, allowing us to detect them using eDNA for conservation and biosecurity monitoring. We have developed assays for the following invasive species in the region: Cane toads. Cabomba (fanwort). Mozambique tilapia. Spotted tilapia. Electric ants and tropical fire ants. Ornamental fish species (Siamese fighting fish, southern platyfish, green swordtail, sailfin molly, and walking catfish). We have also developed assays for these endangered species: Sawfish, including largetooth sawfish, dwarf sawfish, longcomb sawfish, and knifetooth sawfish. Dugong. Rainforest frogs, including Australian lacelid frog, armoured mistfrog, and torrent frog.

Environmental DNA (eDNA) is genetic material shed by organisms into their surroundings, such as water or soil, which scientists analyse to detect and monitor species without directly observing or capturing them. TropWATER Explainer: eDNA 12 May 2025 TropWATER BACK What is eDNA? Environmental DNA (eDNA) is genetic material that organisms have left behind in the environment where they live – in water, soil, or air. Blood, skin, mucus, excrement, and other cells can all contribute to eDNA. Any organism with DNA, from animals and bacteria to plants and fungi, can potentially leave behind traces in eDNA – but some organisms naturally shed more eDNA than others. How do we measure it? Water, soil, or air samples are collected in the field. In the lab, DNA is isolated from environmental samples and screened for presence of a particular species using species-specific genetic markers. The extracted DNA can also be sequenced to target all organisms contained in the environmental samples; this technique is called eDNA metabarcoding. This technique allows scientists to detect multiple species at once by targeting a shared fragment of a gene. Different approaches to sampling and detection may be necessary to suit the unique characteristics of target species or sampling environments, such as fast-flowing water, estuaries, and the ocean. How are we using eDNA? eDNA allows scientists to detect organisms without sighting them, which is valuable for many ecological applications. Our researchers are using eDNA for: Early detection of invasive species. Insights into the range of species living in an ecosystem. Engaging with citizen scientists for biodiversity assessments. Detecting endangered species. Monitoring species that may be difficult to observe. Sample collection for eDNA analysis is cost-effective and relatively simple. Citizen scientists can play a key role in collecting samples, allowing for analysis over large areas, and local communities can lead environmental monitoring efforts. From finding endangered species to strengthening biosecurity, eDNA is a powerful tool to address a range of ecological challenges.

Our long-term environmental monitoring of port industries is extensive, covering coral, water quality, seagrass, and biodiversity. Gladstone, Hay Point, Mackay, Abbot Point, Townsville, Mourilyan Harbour, Cairns, Thursday Island, Weipa and Karumba Location We lead long-term monitoring and assessment programs in all of Queensland’s tropical trading ports, including assessments of seagrass, ambient water quality, and coral. Environmental monitoring and management help ports better manage their environment and nearby coastal ecosystems – our science provides the solutions industry needs for improved environmental outcomes. Our teams inform port management, guide government policy, contribute to regional report cards, and lead innovative research. Key points Long-term monitoring for port industries: coral, water quality, seagrass, and biodiversity BACK Partnering with ports for environmental management The expansion and maintenance of port facilities across northern Australia is a high-profile environmental issue, especially on the Great Barrier Reef coast, where there are 12 trading ports. Port activities like dredging and shipping can damage seagrass , coral, and marine life if not carefully managed. We have strong partnerships with port authorities in the region, founded on our long-term monitoring programs that provide crucial data to inform port management as well as contributing to significant applied research programs. Monitoring seagrass We annually monitor seagrass at 10 ports across Queensland and conduct baseline assessments and mapping in the majority of ports throughout the state – assessing over 1,660 square kilometres of seafloor. Seagrass monitoring is our most established long-term program and among the longest continuous seagrass monitoring efforts worldwide. For decades, these programs have been delivering valuable data that inform management decisions, feed into state and environment reporting, and advance understanding tropical seagrass ecology. We use the following methods: Intertidal seagrass meadows are surveyed by helicopter. Subtidal meadows are surveyed from boats using drop cameras or sled tows. Seagrass meadow characteristics are recorded, such as meadow area, species composition, above-ground biomass and sediment type. Each year we survey key meadows near port infrastructure and reference sites, and every three years we complete surveys of all seagrass meadows within port limits. This long-term monitoring program provides valuable insights into seagrass meadow dynamics, including seasonal and year-to-year changes as well as impacts from extreme weather events. Data on seagrass health and resilience ensures port activities are not impacting seagrass meadows and allows for strategic planning of maintenance dredging and infrastructure development. Monitoring ambient water quality Flood events, runoff from catchments and port activities such as dredging and shipping can all increase turbidity, reduce light, and alter nutrient and chemical balances. This can reduce water quality and impact seagrass, coral, and marine life. Since 2014, We’ve monitored water quality in ports since 2014, and now survey over 100 km of coastline at 12 sites. Every 10 minutes, loggers on the seafloor at sites close to seagrass and coral reefs measure: Water turbidity. Light. Temperature. Depth. Wave pressure. Every eight weeks, we record: Water temperature. Chemistry (including nutrients and heavy metals). Dissolved oxygen and pH. Electrical conductivity. This work helps us to understand ambient conditions and to guide decision-making for port-related activities. Monitoring inshore coral Inshore reefs located close to ports infrastructure can be at increased risk of biodiversity loss and coral habitat health decline associated with poor water quality. As part of our monitoring program, we work with port authorities and regulators to provide reliable data on long-term coral health. We monitor inshore coral reefs twice a year at three ports: Abbot Point, just north of Bowen, and the ports of Hay Point, and Mackay in central Queensland. This program fills critical gaps in monitoring data of inshore reefs in the central and southern Great Barrier Reef. Our team measures the following at multiple reef locations in each port: Coverage of coral and other reef communities. Juvenile hard coral recruitment . Signs of stress including bleaching, disease, sediment deposition and damage, corallivorous Crown of Thorns starfish, and Drupella snails. This work provides valuable data on inshore coral conditions to understand natural fluctuations and responses to environmental disturbance. These findings can then inform coral health monitoring and management in areas potentially impacted by port expansion or dredging. Investigating biodiversity Alongside our long-term monitoring programs, we are investigating the biodiversity within port infrastructure. This helps us better understand what species are present, how they are using these environments and how we can improve human-made infrastructure to support marine species. This work includes: Using satellite and acoustic tags to track manta rays and understand populations and movements around Abbot Point. Informing better design of seawalls by investigating the thermal tolerance of oysters – with findings showing that oysters avoid the high temperatures of sun-facing seawall boulders. Underwater video surveys and side-scanning sonar to understand fish communities around port facilities. Developing artificial intelligence (AI) approaches to automate image processing for video surveys. Partnering for impact The impact of this long-term monitoring extends beyond the programs to contribute to regional reporting and form the basis of cutting-edge research. Each of the monitoring programs provides valuable data to regional report cards on waterway health. The report cards are a key annual update on the health of the region’s waters, with our monitoring programs contributing significantly to the marine scores each year. Our monitoring programs and ports partnership have also formed the foundation of additional research projects and collaborations, including an Australian Research Council Industry Linkage Grant on restoring and future-proofing seagrass , a project using novel tools to assess the fish and crustaceans using these habitats , and Project Blueprint . Project details This work is conducted in partnership with North Queensland Bulk Ports Corporation, Ports North, the Port of Townsville, and Gladstone Ports Corporation.

Assessing the body size and body condition of dugongs using drone-based photogrammetry Assessments of individual animal health and condition can signal early signs of population-level effects in wildlife from environmental and anthropogenic factors. TropWATER PhD opportunity – James Cook University 22 May 2024 TropWATER BACK Dugongs and drone-based photogrammetry Assessing the body size and body condition of dugongs using drone-based photogrammetry Assessments of individual animal health and condition can signal early signs of population-level effects in wildlife from environmental and anthropogenic factors. Animal health assessments relying on wild animal captures can be challenging, hindering our understanding of the well-being of populations. In marine mammals, photogrammetry techniques have been applied broadly for measuring body size and estimating body condition of several taxa, including manatees. These methods produce reliable body length and nutritional health estimates and can be used to investigate trends in growth and survival, and to identify regional differences in morphometric patterns. This project will test and validate photogrammetry methods using small aerial drones for accurate morphometric measurements of dugongs’ body size and condition. The student will also utilise this tool in the field to answer different ecological questions relating to nutritional health in dugongs. The student and their supervisory team will work with multiple partners including academics, NGOs, and Traditional Owners and indigenous and non-indigenous land and sea rangers to collect dugong imagery data to identify regional differences in morphometrics of dugongs in places of high dugong conservation value. In return, partners may be trained to conduct drone-based body condition assessment themselves. The student will be based at James Cook University, Townsville, Queensland, Australia, under the supervision of Dr. Christophe Cleguer (JCU) and Associate Professor Fredrik Christiansen (Aarhus University). Travel to Europe (Denmark) may be necessary during the course of the PhD. Requirements The successful applicant will have a First Class Honours (or equivalent) in biological science or a related field and will pick up extra points in the scoring system if they have a first-authored paper. Preference will be given to those applicants with previous experience in marine mammals’ biology/bioenergetics and evidence of strong bio-statistical and programming skills. Proven experience in working with Indigenous communities is preferred. Journal publications in these fields are desirable but not essential. Applicants must apply by 25th April 2023. Applicants will need to be familiar with the JCU Higher Degree by Research Requirements. Funding A 3.5-year stipend scholarship co-funded by JCU and the National Environment Science Program (NESP) is provided ($29,900 pa for 3.5 years, tax-exempt). Funds are available to support equipment purchase and initial field implementation. Contact Interested applicants should send their 1) CV, 2) academic transcript, and 3) a short (max. 1 page) letter outlining their suitability and interest in the project to Dr. Christophe Cleguer at Christophe.cleguer@jcu.edu.au .

We surveyed over 250 km of coastline with First Nations partners to assess the impact of flooding caused by Tropical Cyclone Jasper, one year after the flood event. Far North Queensland Location One year after the extensive flooding caused by Tropical Cyclone Jasper, we surveyed over 250 km of coastline to assess the impacts on mangrove forests, inshore coral reefs, and seagrass habitats. We identified severe damage to mangrove forests and found that mud still smothers many inshore reefs. Ongoing monitoring will track ecosystem recovery, with 2025 surveys planned to also pinpoint priority areas for coral, mangrove, and seagrass restoration trials. Key points Assessing the impacts of flooding after Tropical Cyclone Jasper BACK Flooding from Tropical Cyclone Jasper Tropical Cyclone Jasper made landfall in Far North Queensland as a Category 2 storm in December 2023. The slow-moving storm system brought record-breaking rainfall to the region, causing widespread flooding that washed sediments across coastal habitats. The affected region included parts of the Wet Tropics of Queensland and Great Barrier Reef World Heritage areas – home to valuable mangrove forests, intertidal fringing coral reefs, and seagrass meadows. These coastal habitats are vulnerable to the impacts of terrestrial runoff, including sediment-laden floods. Surveys of the affected region are needed to understand the environmental impacts of the flooding, potential for recovery, and priority areas for restoration before these ecosystems face another disturbance. Initial assessments can then be followed by monitoring to track recovery over time and inform management decisions to support these valuable coastal ecosystems in the future. Surveys in 2024 with First Nations partners Our researchers partnered with Jabalbina, Yirrganydji, Gunggandji, Gunggandji-Mandingalbay Yidinji and Mandubarra Rangers to survey coastal habitats from Cooktown to just south of Cairns. Together, we assessed the impacts of the flooding on mangrove forests, inshore coral reefs, and seagrass meadows and identified potential sites for restoration, using: Helicopter surveys to assess intertidal inshore areas across more than 250km of coastline, including mangrove condition and benthic habitat cover. Boat surveys to record subtidal benthic habitats – including algae, coral, and seagrass – and mangrove condition in the Daintree River. Drone surveys to assess reef top habitats at Struck Island, Unity Reef, and Ganyjira Reef. Remote sensing to map mangrove cover and condition using satellite imagery before and after flooding. Damage, recovery and potential restoration The team found significant damage as well as some signs of potential recovery across the habitats they surveyed: Mangroves: Extensive damage to mangrove ecosystems across the region, particularly in the Bloomfield River and Daintree River. Large areas of mangrove trees were flattened and uprooted, with significant shoreline scouring and erosion. There were also other forested areas where the breathing roots of mangrove trees were buried in mud and silt. Losses from erosion damage to mangrove cover of around 19 square kilometres, with early signs of patchy regrowth in the 12 months since flooding. Delayed, ongoing damage and loss of mangrove trees in areas where trees survived but had roots buried by sediment deposition. Corals: Many intertidal fringing coral reefs remained smothered in mud, blocking the sunlight needed to sustain existing corals and preventing new coral recruits from becoming established. Coral presence at Hope Isles, Snapper Island, Low Isles, and Double Island, but with significant losses in coral cover. Seagrasses: Eight seagrass species spanning over 35 square kilometres, and just four species in the north of the region where impacts were most severe. Despite the low cover, these seagrasses show signs of potential recovery if conditions remain favourable. Assessing the impact on seagrasses was challenging due to limited data being available on seagrasses in the region prior to Tropical Cyclone Jasper, highlighting the need for expanded monitoring programs. Late in 2025, the team will return to the area to track natural recovery as well as ongoing impacts. These follow-up surveys will also identify sites for small-scale restoration trials, designed to test techniques and locations where restoration efforts may be most effective. Future monitoring efforts will use satellite mapping, aerial surveys, and field monitoring to continue to assess habitat condition and recovery, and to guide potential restoration and mitigation options.
