Their mission, however, has all the trappings of an old-time sci-fi novel – to find a mate for what is arguably the world’s loneliest creature: the Encephalartos woodii. As the couple attempts to unite these millennia of biology with the latest technology in drone imaging, hearts soar and imaginations run wild, evoking what can happen when humanity’s inventiveness meets nature’s resilience.
E. Woodii, a relic from a bygone era, is a cycad, a primitive plant that long preceded the dinosaurs, having emerged from the fossil record a little more than 300 million years ago. The plant’s persistence through eras, surviving where countless others had vanished, reflected its ultimate adaptability. And yet, despite its primordial pedigree, the E. woodii’s survival was in the balance because, without a female of its kind, it was moving through the otherworldy motions of an extinct species.
The plant’s saga began in 1895, when the colonial botanist John Medley Wood discovered the last wild individual. All subsequent plants have been male, presumably deriving from a single sexually immature tree. Natural reproduction remains a fanciful hope. The E woodii has become a symbol of survival and loneliness; a triumph of endurance, but an elegy for frailty.
So-called ‘living fossils’, cycads are among the most ancient of the world’s surviving plant groups; the Age of Cycads, which peaked during a warm and humid Mesozoic era, is a time of tremendous proportion as well. Despite the fact that they bear a surface resemblance to either ferns or palms, cycads occupy a peculiar footnote in the tree of life. Their reproductive strategy, unchanged for millennia, plays out through the giant cones that they produce. It does so in a long, involved dance between male and female plants involving specific insects.
With no female E woodii in sight, researchers have turned to drones. Lightweight and durable, the machines can fly quickly and efficiently through forests, often visiting a single tree and picking up more fertile flowers than a human could find in days. Travelling much faster on the ground than researchers, drones allow them to cover a greater area and map a territory far beyond the range of their footsteps. With their high-resolution imagery and innovative mapping, drones offer a perspective from above, and can help turn a search for a rare plant into a calculated mission of hope.
The discovery of a female E woodii would be of profound importance. All known specimens of this species are clones, making them highly susceptible to disease and ecological changes. The story of E woodii reveals a lot about the wider issues facing global biodiversity. The ability of a species to survive depends on how much genetic diversity it has available. If E woodii naturally reproduces, its prospects for the future would become a reality, not just a dream.
As species worldwide face extinction at an unprecedented rate, the story of E woodii can provide hope for global conservation efforts, symbolising a mission to live and, in particular, how technology might be used to preserve the planet’s diverse life. The search continued for the missing female. As of press time, her identity remained unknown, but the tale of E woodii continues as the quest for life goes on. For the long run, what can we infer? E woodii is hope for the future – a testament to resilience and the perseverance of nature despite odds, and of the harmony between humans and nature when we try.
Drones, as technological wonders, are essential to global conservation efforts for the reach of drones enables access to remote areas, the gathering of in-depth aerial imagery and the mapping of landmasses at high resolution. The drone effort in the quest for E woodii amplifies how when technology meets conservation, today and tomorrow can intersect to meet the challenges of life on Earth. From the eye in the sky, a symbiosis of technology and nature animates life for all living things and forges a path to a sustainable and biodiverse planet.
