Threat assessment of natural habitats in Finland 2018

Threat assessment of natural habitats in Finland 2018 This data includes occurrence data compiled in the 2018 threat assessment of natural habitats in Finland (Kontula & Raunio 2018) in a 10 km x 10 km grid of 152 habitats. The Red Book of Habitats presents the results of the 2018 threat assessment of natural habitats in Finland. A total of around 400 habitats were included in the assessment, of which 48 % were assessed as endangered. Of the habitats missing from this spatial data set, only general focus maps have been compiled, which can be found in the online service of the Red Book of Nature Types by habitat type. The material shows the presence of habitats in a 10 km x 10 km grid. The material describes the presence of habitats in five categories: 0 = absent, 1 = occurring, 2 = fell area separately, 3 = sure, 4 = possible. The material is divided by the main habitat groups in six different files: Baltic Sea (Baltic Sea), LuTUKalliotKivikko (Kalliot and rocky), LuTUMets (Forests), LuTUSwaters Beaches (Inner waters and beaches), LuTUSuot (Surves) and LuTUTunturies (Tunturit). Background The threat of habitats was assessed for the second time in Finland. The evaluation moved to the international IUCN Red List of Ecosystems methodology. The main criteria for assessment were the change in the number of habitat types, the change in abiotic and biotic quality, and the rarity. The current trend in the status of habitats was also assessed. The second assessment of natural habitats in Finland was carried out in 2016-2018. The threat assessment was carried out in broad-based expert groups involving over 120 experts in ecology, hydrobiology, forestry, geology, geology, geography and other fields from research institutes, universities and administration. The project is coordinated by the Finnish Environment Institute and funded by the Ministry of the Environment. The material is part of SYKE’s open data (CC BY 4.0).

In all, the threat assessment covered ca 400 habitat types, 48 % of which were categorised threatened in Finland. The distributions of the habitat types missing from this data are less known and can be illustrated only on a general level as distribution focus maps (available at lutu, in Finnish). Occurrence data of habitat types in 10 km x 10 k grid cells is given in five classes: 0 = not occurring, 1 = occurring, 2 = occurring, northern fell area separated, 3 = certainly occurring, 4 = possibly occurring. The data set is divided into six different files according to the main divisions of habitat types: the Baltic Sea, rocky habitats, forests (LuTUMetsat), inland waters and shores, mires and fell habitats. Background The threat status of Finnish habitat types has been assessed for the second time in 2018. The IUCN Red List of Ecosystems Categories and Criteria was adopted as the assessment method of the second assessment and it replaced the former national method that was used in the first assessment. The primary assessment criteria used were change in habitat type quantity, change in abiotic and biotic quality, and rarity. The current trends for habitat types in terms of their state were also assessed. The threat assessments of habitat types were carried out in 2016-2018. The assessment involved more than 120 experts from various research institutions, universities and agencies. The work was coordinated by the Finnish Environment Institute (SYKE) and funded by the Ministry of the Environment.

The European Environment Agency’s (EEA) reference grid has been used to compile spatial data.
