Pilar García Manteca, technical coordinator of the LIFE Fluvial project, has participated in the VI National Congress on Invasive Alien Species and I Iberian Congress on Invasive Alien Species, an event whose objective is to share the advances and new challenges presented by the management of Invasive Alien Species (IAS) in the Iberian Peninsula.
Three workshops analysed the problems associated with aquatic ecosystems, the relationship between IAS and emerging diseases in Europe, as well as bioethics in biological invasion management programmes.

Alien species with invasive behavior are one of the greatest threats to biodiversity. The LIFE Fluvial project has acted in five river basins of the Iberian northwest through restoration actions of alluvial forests of Alnus glutinosa and Fraxinus excelsior (priority habitat 91E0*) investing part of its efforts in the control of more than 40 species of allochthonous vascular plants, without using any phytocide. Multiple manual and mechanical methods have been used for their elimination, selected from the existing literature and some modifications of these. We present the results obtained in the control of some species of difficult eradication such as Eucalyptus globulus, Tradescantia fluminensis and Arundo donax in order to reduce the work time and the consequent economic cost in environmental restoration works.
The results show that the mulching technique with black tarpaulin significantly decreases the regrowth rate in the three species. This method can be of help in areas with a high degree of invasive plant occupation, saving efforts with respect to repeated manual grubbing techniques.
