We find in France two main peatlands-types: topogenous Carex-fens, in the north and east of the country, and ombrogenous Sphagnum-bogs, in the medium montanes. In total, there are about 100 000 ha peatlands which correspond to a volume of 2 x 109 m3. The amount of extracted peat in France was, in the eighties, 200 000 t (dry matter). Peat is essentially used as fuel or, mixed with German or Soviet peat, as soilless substrates. The fens of the floodplains have long been used for market gardening (tradition of 'hortillonnages' in Amiens or Bourges). Two national surveys were made during energy crises, during the Second World War and at the end of the 1970s following the oil shortage. The law of July 1976 on the preservation of the countryside lists 19 peatlands plant species that are nationally protected. Ten peatlands have been classified as nature reserves and two projects are in preparation.
