20.500.12556/DiRROS-20263 Marine strategy framework directive Descriptor 2, non - indigenous species delivering solid recommendations for setting threshold values for non-indigenous species pressure on European seas Marine Non-Indigenous Species (NIS) are animals and plants introduced accidently or deliberately into the European seas, originating from other seas of the globe. About 800 marine non-indigenous species (NIS) currently occur in the European Union national marine waters, several of which have negative impacts on marine ecosystem services and biodiversity. Under the Marine Strategy Framework Directive (MSFD) Descriptor 2 (D2), EU Member States (MSs) need to consider NIS in their marine management strategies. The Descriptor D2 includes one primary criterion (D2C1: new NIS introductions), and two secondary criteria (D2C2 and D2C3). The D2 implementation is characterized by a number of issues and uncertainties which can be applicable to the Descriptor level (e.g. geographical unit of assessment, assessment period, phytoplanktonic, parasitic, oligohaline NIS, etc.), to the primary criterion D2C1 level (e.g. threshold values, cryptogenic, questionable species, etc), and to the secondary criteria D2C2 and D2C3. The current report tackles these issues and provides practical recommendations aiming at a smoother and more efficient implementation of D2 and its criteria at EU level. They constitute a solid operational output which can result in more comparable D2 assessments among MSs and MSFD regions/subregions. When it comes to the policy-side, the current report calls for a number of different categories of NIS to be reported in D2 assessments, pointing the need for the species to be labelled/categorised appropriately in the MSFD reporting by the MSs. These suggestions are proposed to be communicated to the MSFD Working Group of Good Environmental Status (GES) and subsequently to the Marine Strategy Coordination Group (MSCG) of MSFD. Moreover, they can serve as an input for revising the Art. 8 Guidelines. hidrobiologija morski ekosistemi neavtohtone vrste Evropska unija true false true Publications Office of the European Union Angleški jezik Slovenski jezik Neznano 2024-09-02 12:13:09 2024-09-02 12:13:09 2024-09-04 03:36:26 0000-00-00 00:00:00 2021 0 Luxembourg 2021 Luxembourg Nasl. z nasl. zaslona; Opis vira z dne: 19. 4. 2021; JRC124136 , EUR 30640 EN; 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-03-19 574 978-92-76-32257-3 60207107 https://ec.europa.eu/jrc/en/publication/eur-scientific-and-technical-research-reports/marine-strategy-framework-directive-descriptor-2-non-indigenous-species 1 35d98ba1-6903-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28407 RAZ_Tsiamis_Konstantinos_2021.pdf RAZ_Tsiamis_Konstantinos_2021.pdf 1 EEC42A40DB1A3154132B6B3B64A28357 cb2394c73bb8263a598c762710ce075432234a4d740cdf1a6de8400e5b5c4303 70a79449-6903-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28408 https://publications.jrc.ec.europa.eu/repository/handle/JRC124136 0 86c1b1b3-6903-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28409 Nacionalni inštitut za biologijo 0 0 0
