Weeds of National Significance
From Wikipedia, the free encyclopedia
Weeds of National Significance (WoNS) is a list of the most problematic plant species in Australia as determined by the federal government. Initially a list of 20 taxa were listed and given a rank based on invasiveness, impacts, potential for spread, and socioeconomic and environmental values.[1] An expanded list of 32 taxa was released in April 2012.
