Natural Habitat Types and Species – Essential Parts of Biodiversity

The habitats and occurrences of species requiring urgent protection in state-owned multiple-use forests were reviewed in 2016 on the basis of maps. Some sites were investigated in the wild. The review targeted all habitats of species requiring urgent protection and entered in the registers of the environmental administration.

The environmental administration has estimated that 569 species in Finland require urgent protection. Most such species are invertebrates, mosses and lichens, but the Saimaa ringed seal, arctic fox, golden eagle, Eastern Pasque Flower (Pulsatilla patens) and the Large Blue (Glaucopsyche arion) butterfly are also included. The flying squirrel is not a species requiring urgent protection.

The situation was good in most habitats of species requiring urgent protection in multiple-use forests. Most of the habitats were already protected; they are either in a natural site protected by a decision taken by Metsähallitus, or in an area, including sparsely wooded mires, where forestry is not practised for some other reason.

However, some sites require management or restoration in order for conditions to remain favourable for the species. Two mire sites were restored in Lapland, by removing trees and blocking drainage ditches. Over the next few years, sunlit habitats will be managed in southern Finland in order to ensure more favourable conditions for species dependent on light and warmth.
