Acacia mearnsii and Broussonetia papyrifera added to the EPPO List of Invasive Alien Plants
Following the addition of Acacia mearnsii (Fabaceae) and Broussonetia papyrifera (Moraceae) to the list of species of Union concern (EU Regulation 1143/2014) in 2025 (EPPO RS 2025/226), both species have been included on the EPPO List of Invasive Alien Plants.
Acacia mearnsii is a tree species native to south-eastern Australia. Globally, it has been widely planted as a forestry species and it is utilised as an ornamental. In the EPPO region it can reduce biological diversity by forming dense stands which outcompete native species. Further spread and establishment is likely in the EPPO region as the species can tolerate a wide range of habitats and abiotic conditions.
Broussonetia papyrifera was previously included on the EPPO Observation List of Invasive Alien Plants. B. papyrifera is a tree species native to Asia and is known to be invasive in India, Pakistan and the United States of America. In the EPPO region, it can outcompete native plants and have negative impacts on biodiversity and ecosystem services.
