Chanda Rana is distinct among environmental activists. She dares to go it alone. Rana, chairperson of SEF or Save the Environment Foundation, started her work by using her own resources. She raised a number of environmental issues before her campaign against a plant-killer weed Mikania Micrantha in Chitwan National Park drew national and international concern. Thanks to her lone battle, attention has been drawn to the infestation in Chitwan National Park by Mikania Micrantha.
Although the alien plant started spreading in the forest areas since 1994, it was recognized as a major threat to habitat and grass land of Chitwan National Park just a year ago when Rana brought it to the public notice through a documentary.
