Doing One Thing for the Tamsui River - Remove Mikania micrantha


Mikania micrantha, also called as green cancer, can grow as long as 24cm a day. Its vines entangle trunks and branches form the bottom of trees so trees are unable to perform photosynthesis and wither in the end. Every year from October to March is the flowering and fruiting period of Mikania micrantha. Avoiding this period from April to September is the best time to remove them. The International Union for Conservation of Nature (IUCN) has listed the plant in the 100 of the World's Worst Invasive Alien Species. On 21st August, 2022, Nanya called on passionate employees to protect local environments under the lead of the Society of Wilderness. They removed the alien species of Mikania micrantha at the Wugu Wetland while sweating under the scorching sun. A total of 141.2kg of Mikania micrantha was removed after a half-day effort.

Since 2018, Nanya Technology has cooperated with Society of Wilderness to protect the nearby Wugu Wetland through the planning of various environmental conservation activities.

Since 2020, we expand our response to the issue of "Doing one thing for the Tamsui River", and continue to plan activities such as removing alien species, cleaning beaches, and cleaning mountains.
