Imagine a tree that stood tall when dinosaurs roamed the Earth. Now, picture that same tree on the brink of extinction, not once, but twice. This is the story of the Wollemi pine, a living fossil facing a modern crisis.
Discovered in a remote Australian gorge in 1994, the Wollemi Pine (Wollemia nobilis) was a botanical sensation. Thought to be extinct for millions of years, its rediscovery was akin to finding a living dinosaur. But this ancient survivor now faces a new threat: climate change.
A Relic of the Past
The Wollemi Pine’s history stretches back an astonishing 200 million years. This makes it a contemporary of some of the largest creatures to ever walk the planet. Its unique, bubbly bark and fern-like foliage set it apart, a living testament to a bygone era.
For years, scientists believed the Wollemi Pine had vanished from the Earth’s ecosystems. Fossil records painted a picture of extinction, until David Noble’s groundbreaking discovery in the Wollemi National Park, New South Wales, Australia.
The Threat of Extinction: A second Act
The rediscovery of the Wollemi Pine was a cause for celebration, but it also highlighted the species’ vulnerability. With only a handful of adult trees remaining in the wild, the Wollemi Pine was immediately classified as critically endangered.
Climate change has exacerbated the threats to the Wollemi Pine. Increased frequency and intensity of wildfires, coupled with the spread of diseases, pose a meaningful risk to the remaining wild populations.The devastating Australian bushfires of 2019-2020, which destroyed a significant portion of the wild Wollemi Pines, served as a stark reminder of the urgency of conservation efforts.
Conservation Efforts: breeding a Future
Conservationists are taking proactive steps to safeguard the Wollemi Pine from extinction. One of the primary strategies involves breeding genetically diverse Wollemi Pines in controlled environments. Thes efforts aim to create a resilient population that can withstand the challenges of a changing climate.
The “metacollection” of bred Wollemi Pines is being distributed to botanical gardens around the world. This global network serves as a safeguard against localized disasters and provides opportunities for further research and propagation.
The English Surprise: A New hope
In a remarkable turn of events, a Wollemi Pine in England, owned by a couple at Pear Tree Cottage, produced fruit for the first time. This unexpected development offers a new avenue for propagation and the potential to expand the Wollemi pine population.
Pamela Thompson, the owner and head gardener at Pear tree cottage, expressed her excitement to the BBC, stating, “It would be amazing, absolutely amazing, to have seedlings and to propagate from the world’s rarest tree. I couldn’t imagine being so lucky to do it.”
