ARES(2014)2425342 - 22/07/2014.Organisation and running of a scientific workshop to complete selected invasive alien species (IAS) risk assessments

摘要: The introduction and spread of invasive alien species (IAS) constitutes one the most important drivers global change in biodiversity ecosystem services. Robust risk assessment methods are required for IAS to provide foundation upon which prioritise appropriate action. In a previous study (Roy, Schonrogge et al. 2014) minimum standards were developed an framework assessments ultimately underpinning development proposed list “IAS EU concern”, accordance provisions Regulation (EU) No 1143/2014 European Parliament Council 22 October 2014 on prevention management species. In practice, protocols assessed detail, only four (GB NNRA, EPPO DSS, Harmonia+ ENSARS) sufficiently compliant with be considered these GB NNRA DSS have published assessments. As result, using information from such “substantially compliant” protocols, draft approximately 50 was compiled. It is note that this based availability robust already completed through almost standards, it does not constitute concern”. In view application forthcoming (and building-on ENV.B.2/ETU/2013/0026) Commission hosted 2-day scientific workshop examine selected pool existing knowledge complete missing information, basis evidence, order make them fully wherever possible. The led by Helen Roy (CEH) Riccardo Scalera (ISSG). An additional 16 experts fifteen member states their expertise invasion biology represented breadth variety perspectives including taxonomic (all taxa), environmental (freshwater, marine terrestrial), impacts (environmental, socio-economic health) disciplines (ecologists, conservation practitioners, scientists, policy-makers, assessors). gaps across services climate two invited guide approaches specific themes. total 56 considered. which, when considering score medium high impact, together cover 51 (noting Fallopia japonica F. sachalinensis separate species). Two further suggested consideration Non-Native Species Secretariat follow protocol: coati (Nasua nasua) skunk (Mephitis mephitis), although scored as low impact. Finally three been new European–wide assessments, reported outcome project again Pallas squirrel (Callosciurus erythraeus), grey (Sciurus carolinensis) coypu (Myocastor coypus). main all relation but also benefits mentioned standard “Description (Taxonomy, history, distribution range (native introduced), geographic scope, benefits)” some cases support “Includes status (threatened or protected) habitat under threat“ missing.
