Training course on IAS impact in extreme environments




The Training Course ‘Impact of invasive alien species on biodiversity and ecosystem services in extreme environments’ was organised within the ESENIAS-TOOLS project and held on 03-04 April 2017, in Sofia, Bulgaria. The training course was organised by the Institute of Biodiversity and Ecosystem Research, BAS (IBER-BAS), Bulgaria, Reykjavik University, Iceland, ESENIAS, and the Danube Region Invasive Alien Species Network (DIAS). It was funded by the Financial Mechanism of the European Economic Area 2009-2014, Programme BG03 Biodiversity and Ecosystem Services, under the ESENIAS-TOOLS project, D-33-51/30.06.2015.


The training course aimed at:

  • Capacity building and increasing awareness on IAS impact on biodiversity and ecosystem services in extreme environments among young scientists and PhD students from Bulgaria and the ESENIAS countries;
  • Imparting basic skills and competencies on IAS, its related terminology, the relevant international regulatory framework, networks, projects and information systems;
  • Networking and cooperation among scientists in the ESENIAS region.


The training course was attended by 60 participants,including the lecturers and the organisers. Eleven lecturers from seven countries (Bulgaria, Iceland, France, United Kingdom, R. Macedonia, Poland, and Turkey) were involved in the course. The learners included experts from universities and research institutes, governmental institutions, and students (PhD and MSc), from five countries (Bulgaria, Italy, Serbia, R. Macedonia and Turkey).
