Limited global awareness of invasive alien species and little support for their management

Invasive alien species (IAS) are one of the main drivers of global change and can cause a wide range of negative ecological and social impacts. Addressing these impacts requires management actions, which can fail to be effective when not supported by the public. Here, we conducted the first global survey on people's awareness and perceptions of IAS and support for their management. Our results revealed low public awareness and understanding of biological invasions, and suggest that these are mainly influenced by people's sociodemographic status rather than the social-ecological contexts. Greater awareness of IAS was associated with more negative perceptions toward them and greater support for their management. A large majority of people did not support the use of most management measures. These results suggest that limited public awareness may represent a major obstacle to successfully managing IAS globally, highlighting the need for broader public communication, outreach, and engagement.
