Boreal Baltic islets and small islands (1620)
Short description
Boreal Baltic islets and small islands (according to Habitats Directive Annex I) are groups of skerries, islets or single small islands, mainly in the outer archipelago or offshore areas. They are important nesting sites for birds and resting sites for seals. The surrounding sublittoral vegetation is also included. The distribution map is based on data submission by HELCOM contracting parties. Only Sweden and Finland reported occurrences of boreal Baltic islets and small islands.

Lineage
Data source: Denmark: No reported occurrences of boreal Baltic islets and small islands. Estonia: No reported occurrences of boreal Baltic islets and small islands. Finland: Polygon data on potential distribution of boreal Baltic islets and small islands (underwater parts), modelled based on depth and substrate data. Source: Finnish Environment Institute. Germany: No reported occurrences of boreal Baltic islets and small islands. Latvia: No reported occurrences of boreal Baltic islets and small islands. Lithuania: No reported occurrences of boreal Baltic islets and small islands. Poland: No reported occurrences of boreal Baltic islets and small islands. Russia: Habitats Directive not implemented. Sweden: Polygon data of distribution of boreal Baltic islets and small islands based on depth contours derived from high-resolution depth maps along with information about the surface substrate. Source: Swedish Agency for Marine and Water Management (HaV). Data quality: Data quality and habitat definitions vary between countries. Data is often based on modelling and ground-truthing has not always taken place. The dataset was approved by all HELCOM Contracting Parties in the HOLAS II Ecosystem component data review process during first quarter of 2017. Attribute information: Raster value representing presence (1) or absence (0) of uw parts of Boreal Baltic islets and small islands.
