Most countries in the world have little capacity to deal effectively with invasive species, a study suggests. The spread of non-native species threatens livelihoods and biodiversity, but the issue is worsened by global trade, travel and climate change. They show that one-sixth of the world's land surface is vulnerable to invasion. In what the authors say is the first evaluation of its kind, the paper assesses individual nations' abilities to manage existing invasive species and respond to new ones.
