Austria has a single Natura 2000 site that includes glacial relicts Ligularia sibirica (L.) Cass., which has its area in alpine bioregions: Nordöstliche Randalpen, Hohe Wand — Schneeberg — Rax. Estonia protects the relict species in boreal bioregions from Natura 2000 sites as follows Haanja, Tagula, Sootaga, Edise, Väägvere, Oisu, Anne. On the Croatia territory, Ligularia sibirica (L.) Cass, is spread in the alpine bioregion in Natura 2000 site, Plitvice Lakes National Park. In Poland, the continental and the alpine bioregions host Ligularia sibirica (L.) Cass. species in Natura 2000 sites: Ostoja Szaniecko-Solecka, Suchy Mlyn, Pakoslaw, Polana Bialy Potok, Torfowisko Sobowice, Torfowiska Chelmskie. On the territory of Latvia, the relict species risks the extinction, so the Natura 2000 sites that include the species are found in boreal bioregions: Krustkalnu dabas rezervats, Zusu-Stainu avoti. Ligularia sibirica (L.) Cass, in Romania Kitaibel is the first naturalist who mentions the Ligularia sibirica (L.) Cass, relict in 1796 in Romania, in Taul lui Dumitru swamp. In our country the presence of this taxon from Tardiglacial period till nowadays has been demonstrated through the Wiirmiene age determination of the eutrophic marsh from Natural Reserve Fanetele Seculare Ponoare. Ligularia sibirica (L.) Cass, is considered a hemicryptophyte, Boreal-Eurasian, mesohygrophilic, microtherm, acid-neutrophilous and polyploid species. The taxon grows at altitudes between 407 m in Bosanci (Suceava) and 2100 m in Caraiman (Bucegi), as well as on the territory of 11 counties. In Romania, Ligularia sibirica (L.) Cass, relict follows the wetlands from sites such as: meadows with water at the surface, eutrophic marshes, peatbogs, marshy meadows, wet woods, tail-herb sites, along the river valleys of the mountain and from subalpine level. The relict occupies limited areas in 32 Natura 2000 sites, with a large percentage in Eastern and Southern Carpathians. This taxon of community importance is growing on organic soils, eutrophic or oligotrophic peat, podzols, alluvial soils, from upper mountain level to lower alpine level. The 32 Natura 2000 sites of community importance that protect the Ligularia sibirica (L.) Cass, species in Romania, are located in the continental and alpine bioregions, where there are found some of the most optimal conservation conditions across Europe. In our country, Ligularia sibirica (L.) Cass, is located in four habitats: 7140 Transition mires and quarking bogs, 7230 Alkaline fens, 6430 Hydrophilous tall herb fringe communities of plain and of the montane to alpine levels, 3220 Alpine rivers and the herbaceous vegetation along their banks. Natura 2000 sites declared in 2007 and 2011 for Romania, for the conservation of the relict species, are distributed in alpine and continental bioregions. The most sites are located in alpine bioregions such as: Bazinul Ciucului de Jos (HR), Borzont (HR), Bucegi (PH, DB, BV), Cälimani Gurghiu (HR, MS, BN, SV), Ciomad-Balvanyos (CV, HR), Ciuca§ (PH, BV), Cozia (VL), Gäina-Lucina (SV), Gutái - Creasta Cocosului (MM), Harghita Mädära§ (HR), Igni§ (MM), Mlajtina dupa Lunca (HR), Ciuc Mountains (HR, ВС, NT), Maramures Mountains (MM, SV), Rodnei Mountains (BN, MM,SV), Obcinele Bucovinei (Bucovina’s Ridges) Mountains (SV) 2011, Postävaru Mountain (BV), Retezat Mountains (GI, HD, CS), Apa Linä-Honcsok Peat Bog (CV, HR), Apa Ro§ie Peat Bog (CV), Romane§ti Peat Bog (SV), Ruginosu Zargon Peat Bog (CV), Natural Reserve Tinovul Mare Poiana Stampei (BN, SV), 60
