#video | the drone has discovered a plant that was considered erased from the face of the Earth

In 1991, a cliff on the Hawaiian island of Kauai has been found an extremely rare species of hibiscus called Hibiscadelphus woodii. Then it was discovered only four groups of plants, three of which were subsequently crushed by a falling cliff rocks. The last time the plant was seen alive in 2009, and seven years later it was officially recognized extinct. It turned out that in vain — during the flight over the valley of Kalalau the researchers were able to detect one of the surviving plants. Published by botanists video is recommended to watch all — the views will not leave anyone indifferent.

Hibiscadelphus woodii

A distant part of the valley, Kalalau, which is the only place where you can grow this species of hibiscus, consists of numerous vertical cliffs. Most of her cliffs impossible to climb nor animals nor people, so to explore its surroundings botany are actively using drones with built-in cameras. Their interest is justified, because the area of these rocks is considered a hot spot of biological diversity of the Hawaiian Islands.

Re-open Hibiscadelphus woodii grows as a shrub up to five metres and gives bright yellow flowers that eventually turn purple-maroon. They are rich in nectar and are probably pollinated by native birds — the Hawaiian serpukhovke. It seems that pollination takes place very badly, and to propagate the plant is unable even to botanists — the result was not even allowed to cross-pollination with related species.

Mostly their growth prevent falling off rocks and boulders, as well as invasive plants. New discovery offers hope that endangered species can still grow in hard to reach places. It also once again proved the usefulness of drones — if they do not, examine the vegetation on vertical cliffs of the Hawaiian Islands would be extremely difficult and expensive.
