While the other four horsemen - changing 
land- and sea-use, over exploitation, climate 
change and pollution - are relatively well 
understood, knowledge gaps remain around 
invasive species. The IPBES Invasive Alien 
Species Report is a welcome effort to close 
these gaps. By providing critical information 
on trends in invasive species and policy 
tools to address them, this report can 
provide a springboard to concrete action on 
invasive species.
