- Protected plants

The Roque-Haute Nature Reserve protects almost 600 plant species over the 154 hectares which have so far been inventoried. Of these species, 8% are protected on the national or European level. It is, however, for its exceedingly rare semi-aquatic, primitive, ferns (Isoetes duriaei, Isoetes setacea, Marsilea strigosa, Pilularia minuta) and an amazing variety of mosses and liverworts - 103 species of bryophytes in all - that the Reserve is best-known.
