Forest and aquatic habitat improvement
During our Biodiversity Program we implement at least 200 active forest and aquatic habitat improvement measures.
Forest habitat management supports habitats whose natural values have deteriorated due to habitats becoming overgrown, or human activity. Such habitats may include herb-rich forests, sunlit habitats, burnt areas, areas taken over by invasive species, genetic reserve forests, and sites where certain specific species occur. More than half of the endangered species in forests live primarily in herb-rich forests, sunlit eskers and burnt areas, which means approximately 5 % of the total area of forests. Therefore, management measures focused on these habitats can effectively help a significant share of endangered forest species.
Flowing-water bodies have been cleared for example for the purposes of timber floating and culverts along breeding routes have weakened the spawning conditions of migratory fish. As consequence, migratory fish in Finland have become endangered. The removal of barriers to migration from flowing-water habitats, and the restoration of small waters and brooks, improve the quality of aquatic habitats.
