New paper alert!
Plant Conservation Australia through Outreach Delegate Bob Makinson has led an article on Myrtle Rust and the metacollection approach published in Plants, People, Planet. The article is titled “An extinction-emergency metacollection: Maximising future recovery options for Rhodomyrtus psidioides (Myrtaceae), threatened by Myrtle Rust". You can find the article (open access) here: https://nph.onlinelibrary.wiley.com/doi/10.1002/ppp3.70262
The article outlines the innovative "metacollection” approach to capturing the genetic diversity of a rapidly vanishing rainforest tree (Native Guava) before Myrtle Rust disease wipes it out in the wild - and building a blueprint to do the same for other threatened species. It demonstrates that a coordinated, multi-partner rescue effort can be possible under real-world constraints - including limited funding, logistical hurdles, and the biological urgency of a species on the brink. The hope is that the model offers both a practical toolkit and a note of cautious optimism for the growing list of species facing similar crises.
This work was led by Plant Conservation Australia in collaboration with multiple agencies including the Botanic Gardens of Sydney, Lismore Regional Botanic Garden, UNSW Science, Queensland Environment, Biosecurity Queensland, Booderee National Park (Booderee Botanic Gardens), Australian National Botanic Gardens, Australian Seed Bank Partnership, Dandenong Ranges Botanic Garden and NSW Department of Climate Change, Energy, the Environment and Water.
