Updates

This page contains a quarterly list of full datasheets that have been added or updated. The Home Page shows the most recently published datasheets.

Country datasheets have been enhanced with a List of Species and List of Animal Diseases (generated from the full datasheets only).  In the Home Page Search box enter "USA" or "United Kingdom" or "Florida" or "Netherlands Antilles" for example and look in the Basic Datasheets tab for the datasheet. If you require additional filters, then use the Advanced Search from the top Search menu and refer to the Advanced Search Help for guidance.

Pathway datasheets have been added to the browse tree as Pathway causes (the reasons for introduction and spread, whether deliberate or accidental) and Pathway vectors (the physical means of  introduction and spread). Full and basic datasheets include the List of species transported in the Risks tab. Follow the links to the species datasheets for more information. This data set is being enhanced to provide more extensive lists.
