Andreea Natalia MATEI community importance Ligularia sibirica (L.) Cass., which increases the importance for sonservation of Cirsio waldsteinii-Heracleetum transsilvanici Pawl, et Walas 1949 plant asociation. Materials and methods Species description In this paper is presented the species of community importance Ligularia sibirica (L.) Cass. (Syn.: Cineraria cacaliiformis Lam., Cineraria sibirica (L.) L, Hoppea sibirica (L.) Rchb., Ligularia bucovinensis Nakai, Ligularia lydiae Minderova, Ligularia ucrainica Minderova, Othonna sibirica L., Senecillis sibirica (L.) Simonk., Senecio cacaliifolius var. cebennensis Rouy, Senecio cacaliifolius Sch.Bip., Senecio cacaliiformis Rchb.f, Senecio ligularia Hook, f., Senecio Sibiriens (L.) Clarke. [19] According to the classical system of natural classification, proposed by A. Cronquist, A. Takhtajan and W. Zimmermann, adjusted later by F. Ehrendorfer, system used by most Romanian taxonomists, the relict species Ligularia sibirica (L.) Cass belongs in terms of taxonomy to the following: Domain Eukaryota, Regnum Plantae, Phylum Magnoliophyta, Class Magnoliatae, Subclass Asteridae, Superorder Asteranae, Order Asterales, Family Asteraceae. [9] In Romania Ligularia sibirica (L.) Cass, grows sporadically, being encountered from sessile oak level till the spurce levels in depressions, meadows, grasslands and forests, as well as in eutrophic and oligotrophic swamps, springs and weeds along valleys, from mountain to the subalpine region. [14], [ 1] Taking into consideration the Ellenberg indices, the relict species is considered as an Eurasian-Boreal element, meso-hygrophilic species, that prefers bright areas partially shaded (L ), being a widespread species in temperate zones (hills and submontan areas) (T ), growing on constantly moist and well drained soils but not on excessively wet soils (U;), with preference for moderate acidic soils and for the neutral ones; and from the nitrogen point of view, the studied species is eurinitrophile. [18] Site description Bucegi Natural Park is one of the areas protected by the Natura 2000 network in Romania (Bucegi ROSCI0013), located in the eastern Carpathians, being proposed for protection in 1936 and currently managed by Romsilva. Bucegi Natural Park was established in 2000, owning a total area of 32.497 ha and being on the administrative territory of three counties: Dámbovita, Prahova and Brasov. The park ecosystems are considered to be some of the most complex in Europe, holding a high degree of conservation. Bucegi Natural Park includes many categories of protected areas, therefore the Zänoagei Gorges belong to the Zänoagei-Lucilä 2377 Reserve, located in Dámbovita County and occupying an area of 239.40 ha. [20] The Ialomita river, along which it was found the relict species Ligulaia sibirica (L.) Cass., also crosses the Zänoagei Mica Gorges, Zänoagei Mare, Scropoasa and Orzei Gorges. Relict species had been investigated in the Zänoagei Gorges, in the reservoir lake Scropoasa on the area of Dobresti power station, as well as at the Seven Springs Waterfall, situated in the proximity of Zänoagei Gorges. The Zänoagei Gorges are part of Zänoagei-Lespezi mountain system, with limestone rocks, owning a characteristic cool-wet climate type, with an average annual temperature of 4,9° C, where rainfall varies according to altitude. [20] Plant association and Habitat In the studied area Ligularia sibirica (L.) Cass.species was identified in Cirsio waldsteinii- Heracleetum transsilvanici Pawl, et Walas 1949 plant association. 52
