Need for large-scale data on invasions
Chapman D, Purse B V, Roy H E, Bullock J M. Global trade networks determine the distribution of invasive non-native species. Global Ecol Biogeogr. 2017;00:1–11.
Tracking invasions
Harmonia axyridis
Assessing impacts
Informing policy
A system to address invasive alien species should be
underpinned by a centralised information system collating the
existing information on alien species in the Union and
allowing access to information on the presence of species,
their spread, their ecology, invasion history and all other
information necessary to underpin policy and management
decisions and allowing also the exchange of best practices.

~ 2000 established non-native species
Scorecard 2017 for Great Britain
• 1501 established non-native plants
• 467 established non-native animals
• 272 established invasive non-native species:
– 100 (6.7%) established non-native plants
– 170 (36.4%) established non-native animals

Biodiversity indicators
Where are all the microbes?
The list excluded garden plants, cultivated
crops, pests of stored crops, human
parasites and pests of human habitation
unless they were thought likely to be found
in the wild. Microorganism (with the
exception of a small number of
marine phytoplankton) and
macrofungi were also not included.

Citizen science and alien species
For many countries, the efficiency of invasion monitoring can be improved by inclusion into pre-
existing biodiversity monitoring schemes. Countries may capitalize on citizen
science, as well as emerging online and remote technologies in data
capture to improve records of invasions. For all countries the goal should be to
provide at regular intervals (at least every five years) alien species occurrence data corresponding
to their maximum level of resolution, be it for the national inventory, priority sites, spatial extent, or
the national distribution of occurrence of a priority set of taxa.
