States: knowledge base of Europe’s aliens The DAISIE inventories: • ~ 10 000 alien species identified • ~ 40 000 invasion events documented: date, country, coastline, pathways and vectors, population status, notes, etc... • ~ 2200 references
DAISIE: Mammals • DAISIE dataset includes records of 428 invasion events occurred in 53 countries • 91 species of alien mammals introduced in the 53 geographical areas • 3 species introduced into Israel not considered => 88 spp • 66 (75%) are not indigenous in Europe, 22 native of at least one European country • Number of introduced species per country varies from 1 to 31 (x=8.07, d.s. 6.46), and number of established species ranges from 1 to 12 (ave=4.9, dev.st. 2.79)
DAISIE: Donor areas for Mammals Geographic origin of alien mammals in Europe (n=50 spp established)
DAISIE: Temporal trends for Mammals Invasion events
DAISIE: Temporal trends for Mammals N. new spp introduced into Europe
DAISIE: Temporal trends for Mammals Invasion rate 1500-1800 1800-1950 2000-2005 1950-2000
DAISIE: Main pathways for Mammals GENERAL DESCRIPTION • Accidental transport • Hunting • Escape from zoos • Escape/release from fur farms • Escape/release of pets • Fauna “improvement”
DAISIE: Biogeography of Mammals Most & least widespread species Spp with established populations in > 10 countries • More important!! • 26 spp established in 1 country only; • 13 with not yet established or unknown populations

Conclusions • Biological invasions are a pan-European problem • EU funding has been targeting invasions • National perspectives and audits only tell part of the story • Need to develop comparable baselines and indicators • Better border biosecurity requires coordinated efforts • Require risk assessment tools that apply to Europe • Mobilise expertise and awareness in EU 25 and beyond • DAISIE provides a tool for policy implementation, including • Early warning system • Assessment of impacts • Targeting management
