Nyberg and the National Tropical Botanical Garden (NTBG) team, working with the State of Hawaii's Division of Forestry and Wildlife, have rediscovered three species thought to be extinct or locally extinct from Kauai and uncovered larger populations of many other critically endangered species with populations smaller than 100 individuals.About 10% of Kauai’s plants are already extinct or extinct in the wild, and a further 87% are endangered, according to a 2020 assessment for the International Union for Conservation of Nature’s Red List of Threatened Species.By separating the Mamba from the drone, it can move quickly and precisely in windy environments and avoids the risk of the drone crashing into cliff walls.These include samples of wahine noho kula, a rare violet thought to be extinct on Kauaʻi and only recently rediscovered by the surveying drone.They might even use drones to bomb down collected seeds, packing them into sticky fertilizer balls that can adhere to steep cliffs."
