The Eastern baccharis or groundsel tree is a long-living shrub native to North America. It was first imported into Europe as an ornamental plant and, in some areas, was also intentionally introduced to act as a windbreak along coastal dunes. It is now well established in parts of Belgium, France, Italy, Spain and the United Kingdom where it has spread into a wide range of habitats, including salt marshes, dunes, woodlands and other coastal areas. The shrub can grow into dense impenetrable thickets that choke all other native vegetation, altering the structure of the original habitats and causing serious damage to the ecosystem services they provide. It can also be toxic for livestock. The Eastern baccharis produces abundant amounts of seeds which increases the chances of the species spreading further into Member States. EU-wide measures to prevent further invasion include the prohibition of sales and of keeping, planting or propagating the species. Furthermore, they provide for the rapid eradication of any newly establishing population and the management of existing populations. EU (EPPO) R.A.
