A Monash-led international commentary on the harm caused by biological invasions has urged policy makers to develop conversation targets in a unified framework informed by new data integration methods developed in the last decade.

The call comes as the targets in the Convention on Biological Diversity (CBD) approach expiration in 2020.

Convention - Targets

The convention sets out 16 outcome-oriented global targets set for 2020.

Lead author of the commentary published today in One Earth, Professor Melodie McGeoch from the Monash School of Biological Sciences said invasions by alien species were causing tremendous harm to biodiversity and human well-being.

Species - Traits - Behaviors - Genes - Alter

When species spread outside of their historic geographic ranges they introduce new traits, behaviors and genes and alter ecosystems by introducing new biological interactions, causing species extinctions, and changing habitats.

"The financial burden of damage from alien species is over 5% of the global gross domestic product, and countries spend billions of dollars annually to manage invasive pathogens, weeds and animal pests," Professor McGeoch said.

"But the Convention on Biological Diversity 2020 targets on invasive species were established without mechanisms in...
