The 91-Million-Year-Old Tree Still Growing in a Secret Canyon Near Sydney
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: A species of ancient tree once thought extinct for millions of years was rediscovered alive in a hidden canyon near Sydney, and conservation efforts are now working to protect its tiny wild population from fire, disease, and genetic vulnerability.
📈 One key stat: Only 45 mature wild individuals and 46 juveniles of the Wollemi pine survive in the wild, making every single tree critical to the species’ survival.
💬 One key quote: “A tree thought extinct around 2 million years ago had simply been hiding in the right canyon all along.”
1️⃣ The big picture: In 1994, an off-duty park ranger discovered a grove of living trees in a remote canyon of Wollemi National Park, about 93 miles northwest of Sydney, that science had only known from fossils dating back 91 million years. Named the Wollemi pine, or Wollemia nobilis, the species belongs to a plant family that existed while dinosaurs roamed the Earth. Today, fewer than 100 individuals survive in the wild, all within a single, secret location protected by steep sandstone walls and strict access controls. Threats including Phytophthora root rot, bushfires, and very low genetic diversity keep this ancient tree on a conservation knife’s edge. Strategic propagation programs have placed cultivated trees in botanic gardens worldwide, creating a safety net in case disaster strikes the wild population.
2️⃣ Why is this good news: Finding a living population of a tree family that stretches back 200 million years gives scientists a rare chance to study and protect a species once considered lost to time. New genomic techniques recently detected small but meaningful genetic differences between individual Wollemi pines for the first time, opening new possibilities for guiding smarter conservation strategies. Cultivated trees have been available to the public since 2005, which reduces pressure on the wild population while funding conservation efforts and securing backup populations in international botanic gardens. Emergency fire response during the catastrophic 2019 and 2020 Black Summer bushfires successfully protected the core wild stands, proving that targeted conservation intervention can work even under extreme conditions. Every Wollemi pine growing in a garden or collection around the world acts as living insurance for one of the most remarkable survival stories in natural history.
3️⃣ What’s next: Conservation teams continue monitoring the wild population closely, with authorized access strictly limited to essential staff following full decontamination protocols. Rebuilding the juvenile tree bank in the wild after Black Summer fire damage could take at least 20 to 30 years, making ongoing fire management a long term priority. Researchers plan to use newly discovered genetic data to guide future breeding and translocation decisions, strengthening the species’ resilience against disease and climate pressures.
