An inventory and assessment of invasive alien plant species of Nepal

Biological diversity faces many threats throughout the world. One of the major threats to native biological diversity is caused by Invasive Alien Species (IAS) which can damage or replace native animal and plant populations, as well as the health of our ecosystems. The impacts of IAS are immense, insidious and usually irreversible. The scope and cost of biological alien invasives is global and enormous in ecological, environmental and economic terms. This inventory and assessment is based on experts’ consultation, literature and field studies in collaboration with local partners such as high schools, community forest user groups, community-based NGOs, farmers and other stakeholders.
