WP4: Non-indigenous species

​This Work Package focused on the monitoring of the non-indigenous species occurring in the Baltic. It provided recommendations to harmonize the monitoring and sampling methods for these species to meet the needs of the MSFD as well as the Ballast Water Management Convention (BWMC) of the International Maritime Organization (IMO).

WP4 experts also tested monitoring methods for alien species distribution by conducting sampling in ports using the Joint HELCOM/OSPAR Guidelines on the granting of exemptions under the International Convention for the Control and Management of Ships' Ballast Water and Sediments, Regulation A-4. This activity started with a workshop in October 2013, where the sampling methodology was introduced to the participants. The testing of sampling and analysis was carried out during summer and autumn 2014 in Estonia, Latvia and Poland.

The Work Package was led by the HELCOM Secretariat and consisted of five partners: Estonian Marine Institute (EMI), University of Gdansk (UG), Federal Maritime and Hydrographic Agency (BSH), Latvian Institute of Aquatic Ecology (LIAE) and the Finnish Environment Institute (SYKE).
