Deep in a remote canyon in the rugged wilderness of Wollemi National Park in New South Wales, Australia, scientists once believed the extraordinarily ancient tree known as the Wollemi pine had vanished — possibly millions of years ago. Then, in 1994, a park ranger made a discovery that sent ripples through the botanical world. The Wollemi pine, a conifer whose lineage dates back to the age of dinosaurs, had quietly survived in a hidden gorge.
Today, fewer than 100 of these rare trees remain in the wild — and their future remains fragile. But conservationists are turning a corner: global efforts to breed, propagate and plant genetically diverse Wollemi pines are gaining traction. Seedlings from around the world are now thriving in botanic gardens, and for the first time, some trees grown outside their native habitat are producing cones and seeds — a sign of hope for the survival of this “living fossil”.

Ancient Roots, Modern Rescue
Thought to have gone extinct until its dramatic rediscovery in the mid-1990s, the Wollemi pine was described scientifically just a year later in 1995. Its genetic heritage reaches deep into the conifer family tree: fossil-like characteristics and low genetic diversity tell a story of contraction, survival and fragility.
The wild population is extremely limited — confined to a handful of narrow gorges about 150 km northwest of Sydney. Because their location is so remote and secretive, scientists have been able to implement careful protective measures. But their small number means the species remains critically endangered on the IUCN Red List.

Why They’re so Vulnerable
The Wollemi pine faces several threats:
Fire and climate risk: The trees narrowly escaped the devastating 2019-20 Australian wildfires thanks to emergency interventions.
Low genetic diversity: With so few individuals in the wild, the species has limited adaptive potential.
Pathogen sensitivity: Like many ancient plants, they can be vulnerable to disease and environmental changes.

A Global Effort to Secure the Future
Conservationists are working hard to safeguard the Wollemi pine through a global “insurance population”. Key strategies include:
Propagation and distribution: From about 2005 onwards, cultivated Wollemi pines began reaching botanical gardens and private collections worldwide.
Selecting optimal climates: Research by CSIRO and other scientists revealed the tree performs best with loamy soils, temperate conditions and moderate rainfall — helping determine which gardens could host them successfully.
Creating a metacollection: Botanical gardens are collaborating globally to establish genetically diverse lineages of Wollemi pines — so if wild populations are lost, the species survives.

A Breakthrough: Fruit and Seeds from Abroad
In recent years, something remarkable has happened: Wollemi pines planted outside Australia are starting to reproduce. Cones have been observed in the UK and Europe — indicating that these trees are not only surviving, but reproducing in new environments.
This development is significant: reproduction outside the wild habitat adds resilience to the species’ future — increasing the chance that seedlings will grow, establish and diversify.

Why It Matters to Us All
Living history: The Wollemi pine is a tangible link to prehistoric forests. Some estimates suggest it has remained relatively unchanged for over 200 million years.
Biodiversity and resilience: Protecting such a unique species boosts global biodiversity and helps ecosystems function.
Symbol of hope: The story of the Wollemi pine shows how careful science, propagation and global cooperation can rewrite the fate of a species.

What You Can Do
If you’re inspired by this ancient tree, here are ways to help:
Visit a botanical garden that displays Wollemi pines and learn more.
Support conservation organisations that work with rare plants.
If you have the climate and conditions, consider contributing through sustainable horticulture (respecting regulations around rare species).
Share the story of the Wollemi pine — raising awareness helps generate support for endangered species.

In Summary
The Wollemi pine survived against incredible odds. Yet here it stands — a living relic of ancient forests, now given a second chance through global conservation efforts. With fewer than 100 trees remaining in the wild, its survival is not guaranteed. But by planting, propagating and protecting genetically diverse trees in gardens and arboreta worldwide, scientists and horticulturists are helping this “dinosaur tree” stride into the future.
If we act wisely now, the Wollemi pine may one day be celebrated not just as a botanical marvel of the past — but as a success story of modern conservation.
