Bill Weatherly and Graham Arkinstall
Friends of Forgotten Woodlands
“Collaboration, research, strategy and action for the survival of 3 key Plains Grassy Woodland species’”
Bill Weatherly is a lapsed zoologist and a lapsed farmer who started growing trees 72 years ago and hasn’t found the Off switch. Graham Arkinstall is an ex-geography teacher who discovered early that landcare, community action and education were great partners. He is currently actively involved with several community Landcare projects.
Formed in 2016, Friends of the Forgotten Woodlands Inc. (FoFW) have worked collaboratively with Landcare volunteers, academics, Catchment Management Authorities, government landowners and managers to ensure the survival of the few remaining remnant populations of Banksia marginata, Allocasuarina verticillata and Bursaria spinosa across the VVP.
Through a range of traditional and innovative on-ground activities FoFW have propagated and planted over 45,000 plants over 150 different VVP sites. All propagation has been from remaining remnants. Not all previous remnants still survive! Thousands have been GPS recorded and GIS mapped thus ensuring an accurate and ongoing record for future seed collecting and restoration activities. Several special Seed Production Areas (SPA) have been established for all 3 species. 2080 Climate Matching has been part of the’ SPA Guidelines’.
FoFW has always understood the important role of science to underpin practical activities. Committee members include academics who have guided our decisions to initiate relevant research and our on-ground practices. Genetic studies of VVP remnant banksias, Banksia remnant Drought Tolerance research and SPA genetic mixing are such examples.
Forums and other Information sharing activities have also been central.
Over the past 10 years, FOFW has achieved a lot. There have certainly been many challenges and obstacles along the way but also lots of learnings. We look forward to sharing our story.

Ben Cullen
South Central Area Manager – Trust for Nature
“Private land: A Vital Refuge for Victoria’s Threatened Plants”
Ben Cullen is South Central Area Manager at Trust for Nature and has worked in conservation for more than 20 years. His work has focused heavily on plants, threatened species, ecological communities and the protection and management of significant habitat. He has worked extensively with private landholders and visited conservation properties across greater Melbourne and the Port Phillip and Westernport and Corangamite catchments. Ben is also a conservation writer and broadcaster, sharing stories about Melbourne’s plants, wildlife, landscapes and the people working to protect them.
Many of Victoria’s threatened plants occur on private land, including species and habitats that are poorly represented within the public reserve system. Protecting these places is therefore essential to preventing further loss. Private land can also provide important locations for threatened plant recovery, including translocations and reintroductions. This presentation will explore the role of Trust for Nature’s conservation covenants and owned reserves in protecting threatened plants and their habitats. Drawing on examples from across greater Melbourne and surrounding regions, it will examine what long-term protection can make possible, from safeguarding remnant vegetation to supporting active recovery programs. One example is the conservation and translocation of Rosella Spider-orchid, Caladenia rosella, undertaken through collaboration between Traditional Owners, landholders, Trust for Nature, Royal Botanic Gardens Victoria, government agencies, local government and the Australian Native Orchid Society. This work demonstrates that successful threatened plant conservation depends not only on suitable habitat, but also on enduring relationships, shared knowledge and coordinated action. The presentation will consider how private land conservation can complement the public reserve system, strengthen connections across fragmented landscapes and create secure places in which threatened plants can persist and recover. It will also reflect on the importance of working closely with landholders, whose long-term stewardship is central to protecting some of Victoria’s most significant remaining plant populations.

Dr. Meg Hirst
Research Scientist, Seed Ecology – Royal Botanic Gardens Victoria
“Raising Rarity and Growing Connections: Engaging Young People in Conservation Action”
Dr Meg Hirst is a Research Scientist in Seed Ecology at Royal Botanic Gardens Victoria, specialising in seed biology, germination ecology, and the conservation of threatened Victorian flora. Her research focuses on understanding plant regeneration processes to improve conservation outcomes, ecological restoration, and species recovery. Meg leads the award-winning Raising Rarity school outreach program, connecting students with hands-on conservation science through threatened species projects.
Children and future generations will experience the greatest impacts of climate change, making it essential that they are empowered to engage with environmental challenges through scientific literacy and enquiry. Raising Rarity is a school outreach program that connects students with local threatened plant species and provides opportunities to contribute directly to conservation. Students work with a threatened plant that occurs, or historically occurred, near their school. Through Discovery Days, planting activities and ongoing monitoring, students learn about plant ecology, conservation and the scientific process. They record phenology and environmental conditions, track plant health, and ultimately collect seed for long-term storage in the Victorian Conservation Seedbank.
By contributing to real conservation outcomes, students develop practical scientific skills while strengthening their connection to local biodiversity and place. Their observations also generate valuable information on the cultivation and management of threatened species. Annual Celebration Days recognise student achievements and reinforce the importance of their contribution.
A key strength of Raising Rarity is its flexibility across diverse educational settings, from urban and rural schools to formal and extracurricular programs. Working alongside social science educators, we evaluate student engagement, conservation awareness and climate literacy outcomes.
Through authentic participation in threatened species recovery, Raising Rarity fosters curiosity, connection and stewardship. The program empowers young people to see themselves not only as learners, but as active contributors to plant conservation.
Dr. Susan Hoebee
Senior Lecturer – La Trobe University
“Clear local and regional genomic structuring of populations of the endangered Tiny Spyridium (Spyridium cinereum)”
Susan is head of the Plant Reproductive Ecology and Conservation Genomics team at La Trobe University. Her primary expertise lies with the application of population genetics/genomics to the conservation of native and invasive plants. Her research interests also include studies of mating systems, animal-plant interactions applicable to pollination, pollen viability, and self-incompatibility.
The Black Summer bushfires of 2019–2020 prompted many studies into how fire affected native plants, including the Tiny Spyridium (Spyridium cinereum), an endangered species listed under Victoria’s Flora and Fauna Guarantee Act. In Victoria, the species occurs in two widely separated regions: far East Gippsland and the Grampians. We used this geographic separation to compare the genetic diversity of populations in the two regions. We also examined the genetic differences among plants regenerating on four coastal headlands south-west of Mallacoota, all located within 11 kilometres of one another.
The species regenerated strongly after the fires, and genetic analyses found no clones – meaning the regeneration is from seed. There were clear differences between the East Gippsland and Grampians populations, and distinct genetic groupings among the four coastal headlands, despite their close proximity. Overall, genetic differences between regions were substantial, while differences among the coastal headlands were moderate. Genetic diversity was lowest at Bastion Point, the site closest to Mallacoota, and highest in the two Grampians populations. However, estimated levels of inbreeding were lowest at Bastion Point and highest in the Grampians.
These findings have helped guide conservation seed collection. Particular attention has been given to Bastion Point, where nearby human activity increases the risk of disturbance. Because the coastal populations are regenerating well after fire and each headland has a distinct genetic profile, we recommend that seed collected from different headlands be kept separate rather than mixed.

Yennifer Longo
La Trobe University
“Clonality and Reproductive Capacity in a Critically Endangered Victorian Wattle (Acacia sporadica N.G.Walsh)”
Yennifer is a Master’s candidate working in the Hoebee Lab at La Trobe University investigating the population genomics and reproductive capacity of some of Victoria’s threatened flora (Banksia croajingolensis, Acacia daviesii, A. sporadica). Previously, they were a recipient of a Jim Willis Studentship (2022-2023) where they worked on the creation of a multi-access key to Victorian leafy liverworts. They have a broad interest in botany, conservation, microscopy and bryology.
Understanding what limits successful reproduction is essential for the conservation of threatened species. While many plant species reproduce both sexually (via seeds) and vegetatively (via clones), high levels of clonality can be a sign that normal seed production has failed. The critically endangered Acacia sporadica grows in only three isolated areas within Victoria: Carboor, Howqua and Taradale. All three populations are thought to reproduce clonally, and only Carboor has been observed producing seeds. This study aimed to clarify genomic relationships and measure clonality across all three populations. As two populations do not produce seeds, and clonality is often associated with reproductive failure, pollen function was also analysed. Genetic testing revealed extreme clonality in Howqua and Taradale, which contained only one and two unique genetic individuals, respectively. In contrast, Carboor contained many unique individuals with only minor cloning. Pollen analyses showed complete pollen sterility in both Howqua and Taradale, while Carboor showed low pollen viability (27%). These findings show that severe genetic bottlenecks and pollen sterility severely impair sexual reproduction in the smaller populations of A. sporadica. While cloning allows these populations to persist in the short term, they are at great risk of extinction from unexpected disasters, such as fire or disease. This highlights the need for targeted genetic management, including the possibilities of insurance populations, as well as testing whether transferring pollen from Carboor to the clonal sites can restore seed production.

Assoc. Prof. Susanna Venn
Associate Professor of Plant Ecology – Deakin University
“Alpine Ecosystems in a Snow Free Australia”
Susanna Venn an Associate Professor of Plant Ecology and an Australian Research Council Industry Fellow with the Royal Botanic Gardens Victoria. Susanna chairs the Australian Institute of Alpine Studies and is an executive committee member of the Australian Mountain Research Facility. Susanna’s research focusses on how vegetation patterns and processes drive the ecological functioning of alpine ecosystems, and through this, she aims to improve conservation and biodiversity outcomes under a changing climate for high mountain ecosystems worldwide. She combines manipulative field and laboratory-based studies with long-term monitoring of alpine vegetation, and works closely with land-managers and researchers across global mountain networks.
The rapid transition to snow-free conditions in Australia’s mountains will profoundly affect every alpine ecosystem. While temperatures are set to rise and precipitation to decline, heatwaves and extended summer droughts will likely push plants beyond their normal range of operation.
Experimental evidence suggests that alpine plants have an incredible capacity to acclimatise to heat waves and high temperatures. However, the availability of water during heat events is critical, as is the ‘heat load’ of prolonged exposure to high temperatures. Shrubs tend to cope with heat and drought better than forbs and graminoids. Alpine plants can also adjust their trait expression when exposed to longer-term stressful conditions.
Preparing the mountains for a future without snow will require a thorough understanding of which species are specifically adapted to their local surroundings, and whether flowering, seed development, germination and seedling establishment of alpine plants can all occur successfully without a snowmelt cue, but with a long hot, dry summer. Alpine ecologists will need to work collaboratively with land managers to identify and prioritise the species and ecosystems which are more or less at risk decline, and in doing so Resist, Accept or Direct the trajectories of ecosystem change in alpine environments.
Prof. Peter Vesk
Quantitative Ecologist – University of Melbourne
“Beyond the imperilled; learning about applied ecology of eucalypts of southeastern Australia”
Peter completed undergraduate and Masters at U Sydney, a PhD at Macquarie, a postdoc at Monash, before joining Univ Melbourne as a lecturer in 2005, where he now is a Professor. Research in Peter’s group mainly falls in two fields: (a) the analysis of plant functional traits and types and their generality; (b) predicting, planning and measuring the outcomes of vegetation conservation, management and landscape restoration. Most of the work includes developing and applying conceptual and quantitative ecological models appropriate to the problem at hand. He has a fascination for eucalypts.
Dr. Stanislav Wawrzyczek
Threatened Flora Ecologist – Threatened Species Conservancy
“Why we need more species-focused action to save our rarest plants – case of Ballantinia antipoda.”
Dr. Stanislaw Wawrzyczek is a Threatened Flora Ecologist at the Threatened Species Conservancy, an Australian not-for-profit organisation working collaboratively and across land tenures toward recovering the continent’s most endangered species of flora and fauna. Dr. Wawrzyczek’s background is in botany, conservation genetics, and pollination ecology, with particular focus on vertebrate pollination systems and the Proteaceae plant family.
There are currently 916 plant species listed nationally as either endangered or critically endangered – a considerable proportion of the approximately 24,000 native Australian plant species, of which 85% are endemic to the continent. While not all of them are at imminent risk, 35 species are already extinct. Is enough being done to ensure we do not lose more? Working across land tenures and in partnership with Traditional Owners, land managers, and community groups, Threatened Species Conservancy strives to deliver on-ground conservation action to reverse the decline of our most threatened plants and animals, championing small and non-charismatic species that tend to be left out from priority lists, but are important components of local ecosystems.
One such species is the critically endangered Ballantinia antipoda (Southern Shepherd’s Purse), a tiny annual herb of granite outcrops threatened by invasive weeds, habitat destruction, and fire. Threatened Species Conservancy leads an ongoing collaborative effort to recover this unique plant through translocation and habitat restoration works. The translocation was possible thanks to funding from the Australian Government through the Saving Native Species program, but the capacity to continue this work and deliver more similar projects is undermined by limited funding opportunities at the state level.
