International Legal Framework

The Convention on Biological Diversity (CBD) requires signatory countries to conservation and improving their existing biodiversity and the sustainable usage of their components. All signatories are required to work on the prevention of introduction and the control and the removal of foreign invasive species.

During the preparations for the Convention on Biological Diversity in the international conference “Biodiversity in Europe” held in the Plitvička jezera National Park in 2006 the significance and vulnerability of island ecosystems has been emphasized. Also, the initiatives regarding problem solving of islands foreign species that endanger native species and the economic development of islands were supported.

The Convention on Wetlands (Ramsar Convention) recognizes the influence of foreign invasive species on wetland habitats.

During the 8th Conference of signatories in 2002 a Resolution VIII/18 was passed. With it, the signatories have been called to approach foreign invasive species problem solving, risk assessment for wetland habitats, inventarisation of foreign invasive species on Ramsar areas and other wetland habitats as well as the measures for the prevention of their introduction, control and removal on their own or through joint collaboration.

The Convention on the Conservation of Migratory Species of Wild Animals (CMS) instigates signatories to ensure introduction prevention measures, control and removal of foreign species from their distribution areal providing they endanger the species on the Addendum II of the Convention.

The Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) recommends signatories to consider foreign invasive species problem solving through development of national legal framework regarding flora and fauna trade. The European Union has added four foreign invasive species of animals on their list that regulates wild fauna trade to disable their import into the EU territory.

The European Union emphasizes invasive species as the severe and fast-growing cause of biodiversity endangerment and is currently drafting an act that will regulate foreign invasive species issues on the EU territory. The main guidelines in the European Commission’s document “Towards an EU strategy on invasive species” are prevention and education as well as the control and removal of invasive species.

An expert working group on foreign invasive species acts as a part of the Convention on the Conservation of European Wildlife and Natural Habitats (the Bern Convention). In 2003 within the Convention a European strategy on foreign invasive species has been adopted – it stipulates prevention measure, control and the possibilities of removal of foreign invasive species that represent a threat to ecosystems, habitats and species. One of the expert working groups is the one on the island biodiversity. In its first meeting in 2009 the invasive species issues on island, their control and removal from nature was pointed out as a priority.
