Instructions for using the EASIN RESTful web services

It is possible to filter and retrieve species by:

Substitute the {term} with the species scientific name or part of it. It may lead to zero or more results. The minimum number of characters to start the search is three.

Substitute the {environment} with one of the abbreviations MAR or FW or TER or EST to filter species by, marine, freshwater, terrestrial or estuarine environments respectively.

Species of Union Concern: retrieves all the species of Union Concern.

Substitute {impact} with “hi” to select species with “high impact”, or “lo” to select species “low or unknown impact”.

Substitute {taxa} with Kingdom, Phylum, Class, Order or Family, and {taxa name} with the respective taxa names of interest.

Follows the same logic as for taxonomy single level, by adding the additional taxonomic levels and names to the search to the search form.
