THE SUSTAINABILITY SESSION
Day 1 | Morning | Wednesday, 1st February 2023
To develop and deliver standards, processes, projects, and/or programs that are environmentally, socially and economically justified.
Sustainable Waterways Program: Then, Now, Future, And Forever WA Waterways
Waterways in Western Australia have seen significant changes over the many years since the establishment of Western Australia. Many significant challenges are facing the waterways as we continue to develop and as the population increases. The Sustainable Waterways Program is an opportunity to address key water management challenges in Western Australia by developing a shared vision for WA Waterways, and through collaboration, initiate meaningful, repeatable solutions in readiness for Perth Bicentennial celebrations. The program will bring together key stakeholders and offer a platform for sharing collective knowledge about the Western Australian Waterways, with the aim of positioning the waterways as a key pillar of social, cultural, economic, and environmental prosperity of the State of Western Australia.
Western Australia’s Bicentenary is a rare opportunity to convert the community’s very strong spiritual and emotional connection to the State’s Waterways to impactful social, economic, and environmental outcomes based on weaving together the traditional ecological knowledge and values of the First Nation’s people with western science and community values. This program seeks to deliver meaningful engagement and impact within the complex landscape of the community, policymakers, leaders, Traditional Owners, and decision-makers through Research and a body of knowledge that leads and enables meaningful conversations to protect and help our Waterways to thrive. Facilitated stakeholder workshops nurturing coordinated leadership, governance, management, and policy for future best practice conservation, culture, and community; and the development of meaningful action plans and repeatable solutions. This presentation will be an open invitation to all to join this exciting conversation over the next 10 years and beyond.
Kep Katitjin—Gabi Kaadadjan—Waterwise Perth Action Plan 2
In Western Australia, we use the term ‘waterwise’ to denote a holistic approach to water in all of its meanings and functions. Being waterwise is about showing experience, Katitjin/ Kaadadjan (knowledge in the Whadjuk and Bindjareb dialects), good judgment, and wisdom in how we consider and manage our precious water resources and our connection to them. By adopting waterwise approaches, communities and the environment, including wetlands, can become more climate resilient and make the Boorloo (Perth) and Bindjareb (Peel) region a sustainable and liveable place for future generations. The Waterwise Perth action plan 2019 was the first of successive plans to transition Perth to a leading waterwise city by 2030. The Southwest of WA is one of the world’s regions most affected by climate change, and the Waterwise program to 2030 is part of the State Government’s response to climate change. Released in October 2022, Kep Katitjin – Gabi Kaadadjan Waterwise Perth action plan 2 builds on the success of the first plan and continues the journey to leading waterwise communities for Boorloo and Bindjareb. Kep Katitjin – Gabi Kaadadjan has a greater focus on Noongar values, climate, and heat island impacts than its predecessor. This presentation highlights the benefits of collaboration across government and with stakeholders to improve biodiversity, urban greening, and tree canopy cover, and help to mitigate urban heat impacts. It explains the range of actions, directly and indirectly, supporting wetlands, including water efficiencies, drainage retrofitting, and revegetation programs.
No Roe’d Through The Wetlands - Long Term Community Leadership Leading To A Successful Conservation Outcome
Protected and resorted wetlands and watersheds support a more sustainable, healthy and equitable environment for local communities and ecosystem services. In Ethiopia, wetlands cover nearly 2 per cent of the total land area of the country. They are one of the most productive ecosystems which perform multiple functions that maintain ecological integrity and balance the water flows in the drought-prone and pastoral rift valley sub-region of Ethiopia. Despite this recognition, lack of awareness and regulatory frameworks, unsustainable practices from unregulated and excessive abstraction of water and pollution from international flower companies, unabated degradation of land and watersheds, and encroachments by settlers, farms and animals have accelerated the degradation and loss of these critical wetland resources. What’s the way forward?
Control And Removal Of Invasive Cyprinoid Species Within Western Australian Waterways
Many Western Australian wetlands and rivers have been severely affected by large-bodied pest fish species, such as koi-carp and goldfish. Noxious fish can have devastating impacts on the water quality, vegetation and native fish populations of our precious wetland ecosystems. WRM (part of SLR) have trialled and utilised state-of-the-art pod traps in multiple wetlands around the Perth metropolitan area, as part of an integrated method to remove invasive fish species and increase the health of these wetlands.
Biodiversity, Threats And Solutions For The Sustainability Of Fish And Crayfish In Southwest Wetlands
The wetlands and rivers of Southwestern Australia support a unique suite of freshwater fish and crayfish species. While highly endemic, most of these fish and crayfish species are unheralded as, aside from the iconic Smooth Marron, the vast majority are small-bodied and do not support recreational or commercial fisheries. However, in addition to their inherent biodiversity value, they play important roles in aquatic ecosystems with all of the native freshwater fish being carnivorous, predating heavily on midge and mosquito larvae and pupae thus providing an ecological service to humans. Unfortunately, many of these endemic species are under threat due to secondary salinisation of inland waterways, instream and riparian habitat alteration, introduced aquatic species, water abstraction, and a drying climate. This presentation will shine a light on this diversity, discuss the key threats they face, and present some solutions that are being explored through partnerships between Universities, catchment groups, and local and state governments.
Changing Salinity In Southwest Australian Wetlands: A Review Of The SWWMP Database
DBCA and its predecessors were monitoring up to 159 wetlands as part of the Southwest Wetlands Monitoring Program, which began in 1977. This review looked to evaluate how the salinity and hydrology of these wetlands had been changing in response to chronic long term drying and warming and secondary salinization. Wetlands tend to freshen when wetting and salts concentrate when they dry so these salinity - water depth relationships were examined. Strong salinity - water depth patterns were found to be well represented by power-law or exponential relationships. A model was developed which explained contributions to the exponents of these relationships from wetland bathymetry and hydrology. From the data effects of drying and salinization could be disentangled. Of the wetlands with sufficient data 76% were found to have increasing salinity. In 36% of wetlands the primary cause of this change looked to be the result of salinization and in 40% of wetlands the cause was primarily from drying. Only 13% of wetlands had freshening patterns or no change and the remainder were ambiguous. The SWWMP data demonstrates the benefits of long term monitoring of wetland hydrology and water quality for the assessment of wetland health.
Infiltration Based Stormwater Management For Land Development
Infiltration is one of the best operational and sustainable methods to manage urban stormwater. Until recently, in stormwater management designs and the selection of best stormwater management strategies, the infiltration capacity of different soils were not been considered a major factor. Therefore, stormwater management strategies have failed to adequately consider the criticality of spatially varying soil permeability and their implications on stormwater runoff. Due to the increasing housing density, local land development authorities require stormwater runoff from developing lots to be retained/detained within the property. Due to a lack of information on local soil properties, specifically permeability within the predominant soils in land development areas, it is difficult to assess stormwater retention/detention requirement. This study was carried out in new development areas in the City of Gosnells, focusing on the identification of soil properties and the development of a typology of suitable stormwater management strategies with respect to applicable infiltration capacities.
Can Anthropogenic Wetland Refuges Support Populations Of Threatened Freshwater Mussels Under Drying Climatic Conditions?
THE RECONCILIATION & TRUTH-TELLING SESSION
Day 1 | Afternoon | Wednesday, 1st February 2023
To initiate, support and sustain a proactive partnership with traditional custodians for the conservation of wetlands. This includes increasing participation, support and engagement recognising the importance of traditional knowledge and expertise.
Listening To Women: Intersections Between First Nation And Western Values
The experiences and contributions of First Nation (and other) women remain underrepresented in institutional histories of our lands as well as in large-scale land management. This session will explore the importance of listening to women for advancing reconciliation and for intergenerational learning. This involves placing critical attention on guidance by Elder women, and co-design, creation and curation of knowledge, stories, and sites. We discuss projects that promote an inclusive vision of the past, present, future, in which First Nation women take on important leadership roles. Greater public recognition of women's contribution can demonstrate not only their past impact but also serve to create role models for their future leadership. This is an important intervention as Australia places significant legislative and policy attention aimed at higher levels of inclusivity. This talk will discuss ways to appropriately represent diverse voices, making a direct and critical contribution to today’s discussions about our present, and empowering First Nation women to see themselves as tomorrow's leaders.
Writing Rivers And Wetlands - First Nations Writing On Water
Writing Rivers and Wetlands - First Nations Writing on Water - Walliubup Writing Group and Kep Wangkiny Heathridge is a project funded by the Western Australian Premiers Writers Fellowship 2021. The rationale and aims of this project are to facilitate the creation of river and wetlands poems written by First Nations Authors, that will give voice to their Rivers and Wetlands connections, knowledge, and future concerns. It is my view, and I believe the view of many others, that as many of our rivers and wetlands continue to deteriorate in health, the voices and knowledge of First Nations people are urgently needed to guide how we take action to protect our precious water in the future.
One of the major themes of this work is the role and responsibility of the settler writer or scientist within the Aboriginal lands and waters of Australia. This project utilises a decolonising methodology which primacies the voices of Traditional Owners. Working with Elders Marie Taylor and family, Professor Anne Poelina, Nyikina Warrwa Traditional Custodian from the Mardoowarra, lower Fitzroy River, Deborah Moody and Marion Kickett along the Gululga Bilya Avon River, Lois May, and Carol Foley, together we are working in poetry labs and as individuals to create a polyphonic series of poems that will articulate the voices of the rivers and wetlands and the people that live along them who have millennia-long ancestral connections to them.
Initially, the project had the working title Two Rivers as it was mainly concerned with the Derbarl Yerrigan Swan River and the Martuwarra Fitzroy River. But as the project has unfolded, it seems there are other rivers involved, so the working title has been changed to Writing Rivers and Wetlands, First Nations Writing on Water. The writing groups so far have attracted people from several different places, so we have Whadjuck Noongar participants, Whadjuck Ballardong, Bunuba, Walmajarri, Gooniyandi, and Nyikina.
Prof Anne Poelina comments that ‘river is the first author’ (personal interview), inscribing everything in the landscape and culture that lives alongside it. The river continues to etch its story through seasonal wet and dry patterns. In Nyikina culture, the first ancestor created the river as they traveled through the land. Poelina describes the river as "a gift for humanity to share", a natural heritage asset in common for all beings.
Integrating Western Australian Science And Aboriginal Knowledge: The Two-Way Science Initiative
Connecting Our Hearts: The Significance Of Plant And Wildlife Illustration And The Power Of The Visual Narrative
This paper explores a particular focus on the humanities. Both Indigenous and non-Indigenous examples are discussed. The significance of visual text in the storying of concepts of sustainability within wetlands maintenance, and the restoration of Caring for Country in water places can touch our hearts. In this context, Australia has a rich history of flora and fauna illustration through the lens of colonial art, graphic design, contemporary scientific images, and lovingly, ecological and environmental art. The significance of illustrating the Natural world from an Indigenous standpoint is enfolded in a narrative of the magnificent art from ancient Australian Rock Art contexts, and also the particular cultural art practices that resonate with spiritual connection for Aboriginal and Torres Strait Islander artists. This embodies Traditional knowledge whilst creating with contemporary materials and techniques. This paper asserts the significance and diversity of art expression, with which the role of the humanities in fostering the spiritual, scientific, aesthetic, historic and social value of wetlands and their conservation is demonstrated.
Convincing Enrolling Gardeners - A Personal Journey On Building Community
Ever found that when having conversations about native plants, wetlands, climate change, environmental issues, or science your listeners start to look somewhere else, their body language shifts, or they look at their watch? Do you sometimes find it difficult to listen to passionate people and your mind decides to wander and your ears turn off?
Growing up with Latin and Greek botanical names at the dinner table was so natural that every house did it, right? It was natural for conversations to then continue at school or basketball... except they didn't. The last 50 years were a roller coaster ride about convincing, cajoling, blaming, sharing, being passionate, and having a life dedicated to the 'cause'. Everyone needs to be convinced to connect to the urgency, the destruction, and the importance of wildflowers that all bushland needs to be saved. Right???
Building a community is a personal journey in that they discover how to communicate all things wildflowers and achieve lasting results. How self-work, eco-psychology, and the art of communication have been all involved in developing new tools to communicate about wildflowers and our environment. It has been a roller coaster ride that is not as simple as putting a native plant in the ground.
Today's results are that hundreds of gardeners have fallen back in love with gardening, connect to the joy of wildflowers and become amazed at the colour across the six seasons.
Bringing this lifetime of experience to The Wetlands Centre and Western Wildflower Group is an opportunity to share and continue to learn how to create a community with cultural connectedness and environmental cause.
Creativity As Communication: Engaging Wider Audiences In Alternative Ways
Lisa Fieldhouse and Blake Innes from the Foundation for Indigenous Sustainable Health talk about achieving progression on the journey of reconciliation and truth-telling through creative education programs. Our programs focus on how we can engage our audiences with our themes and issues in different ways that stimulates positive solution-focused contributions, rather than just awareness. The elevation of the literacy rates of First Nation students will only come when the educational material reflects authentic representation of culture and context. The power of giving a student the open range to write and create a vision of their own is an empowering experience that has the potential to elevate that student holistically.
Groundwater Dependence—Lessons Learnt From Working Together On Country
“Water is the life for us all. It’s the main part. If we are gonna loose that I don’t know where we are gonna stand. If that water go away, everything will die. That’s the power of water. He connect with the land. Pukarrikarra (the dreaming) put ‘em all together. One life.”
- John “Dudu” Nangkiriyn – Karajarri Elder
The La Grange area south of Broome is underlain by the Broome aquifer, an extensive freshwater aquifer, which makes rare appearances as small jila and pajalpi (springs and spring ecosystems) as it makes its way to the coast. Being an ancient and dry landscape, the prosperity of the Karajarri people can be traced back through Dreamtime to these rare, permanent, freshwater sources known as living waters.
Since 2018 there has been rapid growth in groundwater applications to support irrigated agriculture in the area, including from the Karajarri Traditional Lands Association. The La Grange groundwater allocation plan triggered the Department of Water and Environmental Regulation to increase our knowledge of these Coastal jila and pajalpi and the hydrogeological mechanisms that support them.
The Karajarri rangers have been an integral part of this learning process. Most water places are sacred cultural sites in Karajarri Country and have specific cultural protocols that must be carried out when visiting. The spiritual significance of wetlands poses a challenge for any kind of work that is done in this area, one that in collaboration, the Department and Karajarri elders and rangers have been working to navigate. The rangers have guided the Department on Country through their work around often remote and difficult-to-reach places. In return, the Karajarri rangers have experienced capacity building and skill development to support their responsibility to look after the country, and aspirations to be informed groundwater users for their own economic growth.
This project hasn’t been without its hurdles so both groups have learned some lessons along the way about the importance of building good relationships and how to do this in a respectful and meaningful way. In this session, we will discuss the way in which together, we have approached scientific research on the Country and share the lessons we have learned.
Archaeology Of Walliabup (Bibra Lake) Wetlands
Fiona Hook, an archaeologist, has been closely involved in the study of the Beeliar Wetlands in Western Australia, a site that has been at the centre of a controversial proposal to construct the Roe 8 highway. In 2013, the Aboriginal Cultural Material Committee (ACMC) initially rejected the plans due to the site's ethnographic significance, but in 2015, the committee reversed its decision and approved the construction without the presence of an anthropologist, as required by the Aboriginal Heritage Act. The committee also allegedly ignored the larger North Lake and Bibra Lake site during the reassessment.
In 2014, the Department of Aboriginal Affairs conducted a dig at the site, concluding that it had been subjected to "high amounts of disturbance" and had no artefacts within its boundaries. However, in January 2017, Hook led a volunteer dig with the aim of determining whether artefacts were still present at the site. The team of 15 volunteers and members of the Whadjuk Noongar community dug 20 shovel pits to a depth of one meter and found stone tools made mostly of quartz 80cm below the surface, as well as fossiliferous chert artefacts and granite artefacts dating back at least 5000 years.
In late 2000 funded by Rehabilitating Roe 8, Fiona Hook led a team of Traditional Owners and archaeologists excavating an additional XX shovel test pits and two excavation areas. Flaked stone artefacts were recovered from 705% of the test pits, with the oldest dated to 10,000 years ago. This evidence expands on the archaeological value identified by a 1973 excavation and discredits the Department of Aboriginal Affairs' findings from 2014. Additionally, the artefacts found indicate that the site was used for trade, as the materials discovered came from the Darling Scarp and were not found locally. The findings support the long-held belief of the Whadjuk Noongar community that the site was a significant camping place with spiritual importance.
THE PARTNERSHIPS SESSION
Day 2 | Morning | Thursday, 2nd February 2023
To initiate and sustain the widest possible proactive participation, support and engagement for the conservation of wetlands.
Rehabilitating Roe 8: How To Deconstruct A Road And Restore Wetlands & Woodlands With Lots Of Community Input
Co-presenter: Lou Corteen, Cockburn Community Wildlife Corridor
Rehabilitating Roe 8 (RR8) is a ten-year project, running from 2018 to 2028. It arose after clearing in 2016 and 2017 for the highly controversial ‘Roe Highway, Stage 8’. The main aim of the project is to restore habitat in the corridor back to its original state (or as close as possible).
There are seven distinct habitat types in the RR8 corridor, making it a complex restoration exercise. These include Wet Forest and Woodland, Banksia Woodland, and the relatively rare Banksia-Woody Pear Woodland.
An integral part of the project is community input. The RR8 Advisory Committee gives guidance and advice to the Project Manager, who implements the on-ground work. The committee is currently made up of 15 members from local community groups, Nyungar groups, community individuals, and a research institute.
On top of this, extra consultation is completed for particular aspects such as the Path Network and Nyungar consultation relating to archaeological surveys. Volunteers are encouraged to take part in planting events and workshops throughout the year. Some groups go above and beyond.
The Cockburn Community Wildlife Corridor is a highly active group, with custodianship over a patch of Banksia-Tuart Woodland in Hamilton Hill. Every fortnight they meet up on Saturday mornings to do hand weeding. This hard yakka avoids the need for chemical weed control and the effects are visible: native daisies proliferate in their patch, while they are absent in the rest of the corridor. The theory is that the non-target effects of herbicides inhibit the recruitment of certain native species.
RR8 shows that land clearing is reversible and that rewilding our cities is possible. The benefits are clear: biodiversity gains, carbon sequestration, giving city dwellers access to nature, reducing the Urban Heat Island Effect, and more. This talk will summarise progress to date and highlight the value of community engagement in this space.
Floating Treatment Wetlands—Replicating And Enhancing Nature
Floating Wetlands are natures superpower for treating nutrients in a water body. In nature these are often formed when a large mass of floating aquatic plants bind together or fringe reeds that are growing from the bank break away from the bank usually during a storm. These island are then able to be colonised by other plants and used as habitat for fish, frogs, birds and aquatic invertabrates. Sam has investigated a wide range of international research and will speak about some of the latest developments and research from the US, Europe and Australia. Floating Treatment Wetland’s are a flexible constructed solution for water treatment and habitat creation improving the efficiency of pollutant removal in traditional water systems by replicating how traditional constructed wetlands and Floating Islands function and increasing the performance of these removal pathways, FTW’s increase sedimentation, plant growth submerged surface area for biofilm formation. The key for nutrient removal is the submerged root structure that provides a great environment for Bio film growth with exceptionally large surface area which allows for a significant increase in nutrient removal.
Future Directions - WA Wetlands Education - Collaboration Is KEY!
In this presentation, Pauline will outline an exciting new partnership between The Wetlands Centre Cockburn and the Harry Butler Institute at Murdoch University which will offer innovative, culturally inclusive educational experiences centred around wetland restoration and conservation. The bespoke resources and programs currently in development will be built as open access, allowing them to be shared by all.
They will initially connect to local schools and communities in the Beeliar region, and be STEM curriculum-linked, featuring how technology is accelerating research in monitoring and restoring wetland ecosystems that incorporate local Indigenous knowledge and skills. Key collaborators include Herdsman Lake Discovery Centre, Murdoch University's Indigenous Education Centres, Kulbardi, and Ngangk Yira Institute for Change. Local Indigenous groups will be partners in all aspects of these new programs for wetland education.
Exciting points of difference will be a strong citizen science context in data gathering to support local research projects including DNA technologies (DNA Barcoding and E-DNA) and an accredited training facility on-site for the native garden horticulture industry. Environmental humanities will be a focus of these programs too, with the wetland precinct at Bibra Lake being developed to provide a community hub for cultural events set in nature.
Towards A Healthier Bindjareb Djilba
The Bindjareb Djilba (Peel-Harvey estuary) is the largest inland waterbody in southern Western Australia and an internationally recognised Ramsar Site (Ramsar 482).
The Bindjareb Djilba Protection Plan is a whole of the government plan to protect the Bindjareb Djilba and its internationally recognised values. Peel-Harvey Catchment Council (PHCC) is working with local Bindjareb people, government, stakeholders, community, and landholders to improve the water quality of the estuary and protect its significant ecological, cultural, social, and economic values. PHCC is leading the delivery of several actions of the plan, including those established under the State Government’s Healthy Estuaries WA program, such as fertiliser management, fencing, and waterway revegetation.
Rural landholders in the catchment are actively contributing to improving the water quality of the Bindjareb Djilba (Peel-Harvey estuary) and its waterways through on-ground actions. Farmers are investing in regular soil testing and evidence-based fertiliser application as well as taking advantage of available funding for fencing to exclude stock from rural waterways and revegetate riparian zones. Supported by PHCC, landholders are overcoming the challenges of historical rural drainage systems and transforming drains originally constructed for water conveyance to riparian landscapes designed to improve water quality and provide enhanced biodiversity and amenity.
This presentation will present case studies celebrating the achievements so far of these partnerships towards a healthier Bindjareb Djilba.
Wetland Funding Proposal Based On The Cranbrook Lakes Conservation Case Study
The Salt Lakes of the North Stirlings are of high avian value but need protection, riparian regeneration, and feral predator control. For the past decade, Green Skills has partnered with the Giliamii Centre of Cranbrook, local farmers, Birdlife WA, and other groups and individuals to support salt lake and shorebird
conservation through a community-based program of 4 activities:
1) Fencing of many lake foreshores;
2) a pilot foreshore revegetation program testing low-cost methods of promoting Melaleuca regeneration of recently fenced foreshores;
3) innovative fox and cat control program linked to shorebird and waterbird conservation;
4) an community engagement program including a field event and citizen-science bird surveys
Turning Science Into Action: The Saving Our Snake-Necked Turtle Citizen Science Program
Co-presenters: Jane Chambers, Stephen Beatty, Catherine Baudains, Vicky Hartill, Rafeena Boyle and Kathleen Broderick
Southwestern snake-necked turtle (Chelodina oblonga) populations within urban environments are in decline. Road mortality and increased predation are reducing nesting female and hatchling survivorship and thereby recruitment. To help combat these threats, in 2019 a citizen science program – Turtle Trackers, was created at the City of Cockburn. Through the program, the community was trained to monitor nesting females and protect their nests. The success of Turtle Trackers in the first few years led to the Saving Our Snake-Necked Turtle project in 2022, to expand Turtle Trackers throughout southwest WA. The project formed partnerships with 12 local councils and six wildlife conservation organisations and was funded by LotteryWest. A key partnership was with a national coalition to save freshwater turtles – the 1 Million Turtles Community Conservation project. This partnership enabled the use of the TurtleSAT application to record observations of turtles and nests into a national database. It also allowed ‘Saving Our Snake-Necked Turtles‘ to broaden the scope of community involvement, with two different levels of engagement in turtle conservation – the everyday community member, and the wildlife warrior Turtle Trackers. Twenty-two education and training sessions were delivered to over 500 community members, leading to the creation of 11 Turtle Tracker Teams. These Turtle Tracker teams went on to observe and protect approximately 500 turtles and over 300 nests. An additional 100 observations of turtles and nesting events were observed by community members using the TurtleSAT application. Our goal is to increase these community observations and protection of both females and nests, to sustain southwestern snake-necked populations in wetlands across southwest WA. The data collected from this citizen science project will inform future conservation management of the species, further enhancing the prospects of the species thriving across its range.
Restoration Of Urban Wetlands For Dragonfly Biodiversity
Co-presenters: Lily Mackintosh, Lillyanne Kop
Dragonflies are some of the most aesthetically pleasing and most loved wetland insects, yet we know almost nothing about the ecology or biology of Australian species. Our research focused on understanding patterns of species diversity of dragonflies to identify the qualities of wetlands needed to maximise dragonfly diversity. The Beeliar wetlands were sampled in spring and summer to collect aquatic dragonfly nymphs, and their exuviae, and to record adult presence/absence at the species level. A variety of water quality, vegetation, and landscape variables were also recorded. We found that vegetation (both aquatic and terrestrial) and water temperature were the variables most important to dragonflies. Dragonfly diversity was highest at wetlands with extensive stands of submerged and emergent aquatic plants and fringing trees, and at wetlands that were connected to other wetlands by native vegetation. This was because dragonfly nymphs use submerged vegetation to hunt and hide from predators and use emergent and fringing vegetation to emerge from the water and transform into the flying adult. Freshwater paperbark trees provide important habitat for metamorphosis and vital shade in summer. Common species tend to emerge as smaller adults in summer than in spring, and this may be due to changes in day length. Laboratory experiments manipulating water temperature and depth showed that while warmer temperatures did not influence dragonfly emergence, declining depths did. As the climate continues to dry and wetlands are inundated for shorter and shorter periods, some dragonfly species may disappear from our wetlands. When restoring natural wetlands or managing created wetlands, it is vital that there is sufficient aquatic and terrestrial vegetation to support dragonflies and that some wetlands retain water all year round.
Nurdi Way Constructed Wetland And Living Stream Project
Co-presenters: Cat Williams–SERCUL, Brett Kuhlman–DBCA, Jason MacKay–Water Corp, City of Canning
Nurdi Way is a typical urban drain, designed to manage ground and storm water, delivering it directly into the Canning River. Urban drainage systems often offer little ecological or social benefit and are frequently vectors for transporting nutrients, sediment, pollution, and weeds through urban environments.
DBCA’s Catchment Monitoring Program identified Nurdi Way as a priority for remediation due to high nutrient and copper loads. The Nurdi Way Constructed Wetland and Living Stream project was designed to improve water quality and habitat outcomes by modifying an open trapezoidal section of the drain into a living stream, diverting the base flow through a constructed wetland.
This project is an impressive example of partnerships collaborating effectively to deliver an outstanding project in a short time frame with opportunistic funding; delivered and implemented by SERCUL, in partnership with the City of Canning, the Water Corporation, University of Western Australia and the Department of Biodiversity, Conservation and Attractions.
This project is supported by the Swan Canning River Recovery program, delivered by Perth NRM through funding from the Australian Government.

THE LEADERSHIP SESSION
Day 2 | Afternoon | Thursday, 2nd February 2023
To increase the knowledge, awareness, understanding, participation, engagement, and commitment to the conservation of wetlands.
Towards A Universal Declaration Of The Rights of Wetlands
Interest in a Universal Declaration of the Rights of Wetlands has been developed through a series of workshops and partnerships initiated by the Society of Wetland Scientists. The essential component of the proposed Declaration is that all wetlands are entities that are entitled to inherent and enduring rights, which derive from their existence as members of the Earth community and should possess legal standing in courts of law. These inherent rights include the following:
- The right to exist
- The right to their ecologically determined location in the landscape
- The right to natural, connected, and sustainable hydrological regimes
- The right to ecologically sustainable climatic conditions
- The right to have naturally occurring biodiversity, free of introduced or invasive species that disrupt their ecological integrity
- The right to the integrity of structure, function, evolutionary processes, and the ability to fulfill natural ecological roles in the Earth's processes
- The right to be free from pollution and degradation
- The right to regeneration and restoration.
The proposal has been presented to delegates at the Ramsar Convention and is being further discussed with local communities and advocates for the rights of nature. The latter has been acknowledged in the Global Biodiversity Framework adopted through the Convention on Biological Diversity. Other steps include placing the suggested rights within the context of decisions adopted by the Ramsar Convention and seeking to understand how these rights support existing wetland conservation ethics and practices and support complementary approaches for ensuring the sustainability and restoration of wetlands. At this stage there is a proposal towards a universal declaration of the rights of wetlands - this is seen as the start of a dialogue with every expectation that the proposal could evolve as more wisdom and knowledge is shared, and legal and policy implications are elaborated.
Wetland Management In The City Of Cockburn
The presentation will comprise of a brief overview of wetland management in the City of Cockburn.
The City of Cockburn is home to numerous wetland reserves including Bibra Lake where this conference is being held.
Bibra Lake and most of the other wetlands within the City form part of the Beeliar Regional Park, which is a network of wetland reserves located in the southern suburbs of Perth. These protected wetlands are a refuge for many plants and animals and a large amount of freshwater allows the local species to thrive. The wetlands are a source of pride for our residents and they also form a key part of the City's identity by featuring on the City's logo and corporate tagline.
Despite this, wetland management within highly urbanised areas does not come without challenges. Visitation to the reserves continues to increase, thus exposing the natural areas to high levels of vegetation degradation, weed encroachment, pollution and other threats.
This presentation will include an overview of the City's day-to-day management of its wetlands to ensure that these threats are managed and that the local ecology remains healthy and resilient. A particular focus will be given towards today's theme of wetland restoration. In addition to this, several key case studies will be presented to highlight some of 'the outside of the ordinary projects that have been undertaken by the City.
Such case studies will include:
- The nutrient stripping basins at Yangebup Lake;
- The bespoke possum bridge over Beeliar Drive that links Yangebup and Kogolup Lakes
- Environmental DNA surveying at Bibra Lake
- The Black Cockatoo Oasis at Bibra Lake
- The turtle trackers volunteer conservation program
- Walking trails.
The City hopes that the presentation will facilitate discussion amongst other land managers about how best to manage our precious wetlands.
The Helena River: A Neglected Jewel
The Helena River Alliance was formed to make a difference by aggregating the people resources of communities with an interest and passion for conserving and enhancing the river system and its heritage in a meaningful, practical manner. The vision of the Alliance is to elevate the profile of the Helena River and set up mechanisms that will protect in perpetuity the uninterrupted green corridor that still exists from source to confluence.
We have recently formed a partnership with ‘Waterways’ under Anas Ghadouani’s leadership and with financial support from the Feilman Foundation to begin the task of developing and implementing an action plan to give the Helena River the respect and protection it deserves. We want to transform the Helena River into an asset for the community of WA and the people of Perth in perpetuity.
Here we will present our joint vision to make this happen.
IoT-Based Real-Time Smart Water Quality Monitoring Systems For Wetland Management
Wetlands, including lakes and reservoirs, are particularly susceptible to the negative impacts of eutrophication, a result of high-nutrient loads from sources such as agricultural runoff and industrial effluents. Traditional monitoring of water quality in wetlands is labour and time-intensive, adding cost and affecting the accuracy of the data. Arnowa has developed an innovative solution to address these challenges.
‘Carbon’ is an autonomous platform that uses IoT sensors to monitor various water quality parameters in real time and transmit the data to a remotely located user dashboard. The platform includes wireless data transmission devices, solar panels for island mode operation, and application software for data analytics. By using big data analytics, AI, and machine learning, the Arnowa system can predict future trends in water quality and aid in preventing water pollution using alerts and reporting features.
The industry and water-intensive sectors need to adapt to a dynamic and innovative approach to wetland management. Arnowa’s water quality monitoring platform addresses the ongoing challenges of population growth, urbanisation, and climate change while optimising processes and operational efficiency. This paradigm shift towards next-generation water monitoring systems is crucial in meeting the increasing complexity and uncertainty of the water management landscape.
Wetland Conservation In WA: Past, Present And Future
Co-presenter: Professor Philip Jennings, Wetland Conservation Society of WA Inc.
Wetlands Conservation in Western Australia has had its ups and downs over the past 100 years. After a significant period of wetland destruction, vocal community members and conservation policies have provided for the protection and conservation of many wetlands. In the last decade, Western Australian politics and policies lead us to the present stagnated status quo that still leaves many wetlands with no protection. In this paper, we will highlight the micro and macro successes of the past, and the current situation and offer a vision for the future that values and protects the wetlands of Western Australia.
Wasteland To Wonderland: Recreating Functioning Ecological Wetlands At Chittering Springs And Spoonbill Lake From Degraded Farmland
Co-presenter: Liz Kington, Chittering Landcare Centre
This is a case study about partnerships, but also the sustainability of two important rural wetland environments on the Ellen Brook and Brockman River; a case study demonstrating leadership in ecological functioning wetland ecosystem restoration.
The Chittering Springs and Spoonbill Lake, both in the Shire of Chittering, were once degraded wet areas on rural farmland; one a waterway, the other degraded land.
Over 20 years ago, this farmland was sold and subdivided into rural-residential smaller blocks. As part of the subdivision, these areas were deemed unsuitable as saleable lots and simply left. Chittering Landcare took them on for the Shire of Chittering and has reclaimed both as ecologically functioning wetlands.
A small dam was built at Chittering Springs on the tributary of Ellen Brook to slow the water flow, transforming this acid-saline area of farmland. The area around the dam was then ripped and weeds were controlled (it was weed heaven!). Progressively, over the next 12 years, the area was restored to a wetland, surrounded by bushland, with all lead-in creeks re-vegetated. Along the way, there were issues to deal with; vandalism of the dam and 4-wheel drivers enjoying the wet-sloppy conditions requiring the area to be fenced. Tronox Mineral Sands and St Mary’s school tree-planting partnerships saw the re-vegetation occur, supported by grants from SALP, contributions from the Chittering Shire, and other funding bodies.
Today, this area is an oasis! Protected by fencing with a community picnic area. Chittering Springs protects downstream Rocky Creek which flows into Ellen Brook, a tributary of the Swan River. The wetland today supports waterbirds, with a habitat created by the native rushes and sedges.
Spoonbill Lake started as a series of farm dams (known as Hart farm). When it was subdivided into rural residential lots, the dams were taken out as a reserve by the local government. Since 1998 this area has been progressively re-vegetated and restored. Annual Chittering Bird Group counts since 2009 show many species of waterbirds and bush birds are now found there. Native rushes and sedges planted in the wet areas complement dryland plants along the upper parts of the creek. Local residents took on this project, helping with planting day events. Government NHT and ongoing SALP grant funding have continued the improvement, with all woody weeds and the more invasive Typha now replaced with other native rushes. Spoonbill Lake is located on fresh-water steam, one of the few entering the Chittering Lakes, which flows into the Brockman River, another important tributary of the Swan River. Since 2006, water quality has improved and the Lake today provides important bird habitat. The Chittering Bird Group has even spotted a Greenshank on its shores. Walk trails for the local residents provide much-appreciated social and health benefits.
Upstream of the Ellen Brook and Brockman River, both these important wetland restoration projects have added to the conservation category wetland systems; a credit to Chittering Landcare, their partners, and the community.
Saving Eungedup Wetlands
In early 2022 a group of concerned citizens and groups got together to buy farmland that was covered in a wetland, Eungedup Wetland, containing several breeding endangered Australasian Bitterns. This case study will examine the importance of the 103-hectare wetland to 'future-proofing' Australasian Bittern populations, its critical role in the Wilson Inlet Catch area for controlling nutrients leaching into the inlet, the difficulties and issues community groups face when trying to buy land for conservation (Including its ongoing management), how they were overcome and the ongoing efforts to raise the funds to buy the land.
Case Study On The Restoration Work Undertaken on 3 Ramsar Wetlands In The SW Region Over The Last 5 Years
Co-presenter: Derani Sullivan, South West Catchment Council
The South West Catchments Council, with funding from the Australian Government’s RLP program, has been working for five years with the Department of Biodiversity, Conservation and Attractions staff and various stakeholders in the South West region, to undertake restoration and conservation work on the three Ramsar wetlands found in our region. These include the Muir-Byenup wetlands located southeast of Manjimup, the Vasse-Wonnerup wetlands found in and around Busselton, and Toolibin Lake located east of Narrogin.
Each of these unique wetlands varies in their ecological characteristics but are very important for local and migratory birds as breeding and/or feeding habitats and it is vital they are conserved into the future.
This talk will focus on the successes and achievements of the wetland restoration works carried out over our five-year Ramsar project, as well as the challenges and some lessons learned along the way. We will discuss the innovative ‘Felixer cat grooming trap trial’ we undertook at Lake Muir, and then also discuss future work that may need to be undertaken to improve the resilience of the wetlands in a changing climate.
