Trends in arrival of new non-indigenous species 2018 (HOLAS 2)
This core indicator evaluates the status of the marine environment based on the arrival of new non-indigenous species. The new NIS have been detected both through regular environmental monitoring activities and incidental sightings. The data have been verified by national experts. Monitoring is not considered to sufficiently cover all areas of the Baltic Sea and hot spot areas for new introductions (e.g. ports) to allow for the conclusion that in areas where no new NIS have been observed there have not been any new introductions.
This dataset displays the result of the indicator in HELCOM Assessment Scale 1 (whole Baltic Sea).
Attribute information:
"level_1" = Name of the HELCOM scale 1 assessment unit
"Area (km2)" = Area of the HELCOM scale 1 assessment unit
"Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”)
"AULEVEL" = Assessment unit level used for the indicator

- Statement
-
Data used in the indicator originates from the AquaNIS database, NOBANIS database scientific publications, the HELCOM list of non-indigenous species and national experts. The indicator covers the entire Baltic Sea: national coastal and offshore waters divided to sub-basins. There are however wide gaps in the spatial coverage of the current biodiversity monitoring especially in the coastal areas. Currently, the monitoring of coastal and estuarine biodiversity is not conducted to reliably show the distribution and abundance of several NIS. The time series data may overemphasize the recent decades and show too steep increase in the rate of introductions due to improved monitoring of NIS.
The confidence for areas where detections of new NIS have been made high.
