Main danger

Mikania micrantha is a perennial vine, which climbs around trees and shrubs in proper places and presses heavily on the top of the crown, which hinders the photosynthesis of attached plants and leads to the death of attached plants. It is one of the most dangerous and harmful plants in the world.

In China, Mikania micrantha mainly harms natural secondary forests and artificial forests, and mainly harms almost all native tree species below 6-8 meters, especially some forests with small canopy density. The severely damaged tree species are mangrove, paulownia, Lagerstroemia indica, Vitex negundo and Ficus microcarpa. The tree species seriously damaged are longan, pistachio, juniper, melia azedarach, guava, Pu Shu, litchi, murraya murraya, Ilex kudingcha, Cinnamomum camphora, Cinnamomum camphora and Sapium sebiferum.
