Surveying and collecting rare plant species that grow on steep cliffs has been a risky business for scientists and conservationists for centuries. The world’s first aerial sampling system, which uses a robotic arm suspended from a drone, is attempting to solve this problem in Hawai’i. An article published by Mongabay magazine back in November 2022 states: „In Hawai’i’s Kaua’i island, the world’s first aerial sampling system has successfully flown into high-altitude cliff faces to cut out samples from rare plants and bring them back to a nursery. Scientists call it ‚the Mamba,‘ a cutting mechanism on a remote-controlled robotic arm suspended from a drone. The system was developed by Hawai’i-based not-for-profit conservation organization National Tropical Botanical Garden (NTBG) and Quebec-based technology company Outreach Robotics and the University of Sherbrooke in Quebec.“ (Mongabay, 9. November 2023) Ben Nyberg, the NTBG’s geographic information system and drone program coordinator, told Mongabay in an interview: „It is really unlocking a lot of areas that have previously been completely inaccessible.“ (Mongabay, 9. November 2023) Of course, criminals could also adopt the technology. But it would be almost impossible to smuggle rare plants out of Hawai’i due to strict customs controls.
