Altogether over 60% of Finland's original peatland area has been drained for forestry, used for agriculture or peat extraction, been submerged under hydropower reservoirs, or developed with buildings and infrastructure. This has resulted in a complete or partial destruction of the original habitats. Furthermore, the connectedness of pristine peatlands has decreased markedly and the shapes of individual peatlands have changed to sharp-edged drainage delimited polygons (Ministry of the Environment 2010). However, recent actions in Finland to restore peatlands are likely to counteract this, at least in protected areas (Simila et al. About 80% of these have been disturbed by human activities, especially by drainage. Bog and marshland are relatively extensive biotopes in Norway.
