Forests are home to the majority of threatened species
According to a 2010 estimate, the number of threatened species in Finland is 2,247, accounting for 10.5 per cent of the estimated total of 21,400 species. The estimated number of species is exceptionally high, even on an international scale.
For the 1,505 threatened species in the previous estimate (10% of estimated species), the situation has improved for 186 species, and deteriorated for 356 species. This proves the continuing trend of species becoming threatened, but also the success of protective measures regarding several species.
Forests are home to the majority of threatened species (36.2%), as do semi-natural habitats and other habitats transformed by man (23.3%). The pace of species becoming threatened in forests and semi-natural habitats has slowed slightly.
Changes in forest habitats are the primary reason for the threat posed to a total of 693 species. The most important changes include the decreasing amount of rotted trees (27%) and forest regeneration, and management measures such as clear felling and mechanical tillage of soil (26%). For a total of 70 species in semi-natural habitats, the situation has improved. With respect to distribution, most of the species affected are southern species such as beetles, butterflies and true bugs. Species in mires, rocks, shores and bare field regions are becoming threatened at an increasing pace.
