Top Highlights
- The critically endangered tree, Dendroseris neriifolia, with only one wild individual left on Chile’s Robinson Crusoe Island, is now being conserved by collecting its seeds for the first time.
- Scientists successfully harvested and stored 29 seeds from the last wild tree, with 25 potentially viable, leading to the growth of seven seedlings at the Millennium Seed Bank in England.
- Due to the tree’s remote cliffside habitat and dangerous access, future seed collection may utilize innovative tools like drones to assist in conservation efforts.
- Seed banking provides a vital backup, enabling research on germination, genetic diversity, and potential restoration to prevent extinction of this rare species.
Scientists Act Quickly to Save a Rare Tree
Scientists are racing against time to save one of the world’s rarest trees, Dendroseris neriifolia. This tree, found only on Chile’s Robinson Crusoe Island, has dwindled to just one wild individual. Habitat loss, invasive species, and other threats pushed the tree close to extinction. To give it a second chance, researchers collected hundreds of seeds from the last known tree. These efforts aim to preserve the species before it is gone forever. The collected seeds are now part of a global effort to protect Earth’s most fragile plants.
Challenges in Collection and Conservation
Getting seeds from this cliffside tree is no easy task. The tree grows on a steep, rocky cliff, making access dangerous and difficult. Rangers use ropes to climb and catch mature seeds in nets. New tools like drones might someday make seed collection safer and easier. Once collected, the seeds travel to the Millennium Seed Bank in England. There, scientists test their viability and begin germination trials. This approach helps create a backup plan if the wild tree disappears. It also offers a way to study the plant closely and learn how to grow more of its kind.
Looking Toward a Brighter Future
While the task is tough, the effort shows hope. Growing new plants from stored seeds could eventually lead to replanting efforts in Chile. This work not only helps save D. neriifolia but also contributes to understanding how to protect other endangered species. Seed banks serve as a safeguard for nature, ensuring that even if wild populations vanish, species can survive in labs and gardens. These actions reflect a positive step in humanity’s care for Earth’s biodiversity and its ongoing journey to protect our natural world.
