For decades, searching for such hard-to-reach plants and collecting samples was carried out by intrepid botanists who rappelled by rope down dangerous cliffs to hunt for what was lost. Now, we may have a little more time before extinction.”DIRE SITUATIONToday, two in five plant species globally are threatened with extinction. Kauai has 250 plant species that can be found only on the island. To protect species in the long run, botanists need to collect samples — seeds and genetic material — which they can cultivate in greenhouse nurseries. They might even use drones to bomb down collected seeds, packing them into sticky fertilizer balls that can adhere to steep cliffs.
