A — Habitats Directive and OUG 57/2007

В — Red list of extincted, threatened and rare species of Romania (N.Boncain, Gh. Coidea, C. Horeanu, 1994),

C — The red list of cormophytes from Romania (M.Olteanu, G.Negrean, A.Popescu, N.Roman, G. Dihoru, V. Sanda, S.Mihäilescu, 1994)

D — Rare, threatened and endemics plants in Romania’s flora (Dihoru Gh., Dihoru A., 1994)

E — Carpathian List of Endangered Species

Considering these Red Lists, the report concludes that in the Transylvanian Plain flora there are currently a total of 46 taxa that are in various degrees of endangerment. It appears that most taxa belong to two sozological categories: vulnerable and rare.

The human impact in the studied area, in addition to the fact that the land it is used predominantly for agriculture increases the number of invasive species. These invasive species includes: Amaranthus retroflexus L. (Adv Am-N), Amorpha fruticosa L. (Adv, Am-N); Acer negundo L. (Adv Am-N); Ailanthusaltissima (Mill.) Swingle (Adv China); Asclepiassyriaca L. (Adv-Am-N); Datura stramonium L. (Adv-Am-N); Echinocystis lobata (Michx.) Torr, et A. Gray (.Echinocystis echinata Britton, Sterns et Poggenb.) (Adv); Erigeron annuus (L.) Pers. (Adv Am-N); Erigeron canadensis L. Adv Am-N); Galinsogaparviflora Cav. Adv-Am-S; Gleditsia triacanthos L. Adv-Am-N); Lycium barbarum L. (China); Oenothera biennis L. (Adv Am-N); Portulaca oleracea L. (Asia-Temp-Adv Neophyt?); Reynoutria sachalinensis (F. Schmidt) Nakai (Adv-Sahalin); Robinia pseudacacia L. (Adv-Am-N); Rudbeckia laciniata L. (N-Am Adv); Veronica persica Poiret (Adv Asiat SV); Xanthium spinosum L. (Adv-Am-S); Xanthium strumarium L. (Cosm-Am).

The presence of the 20 invasive species, especially those that are found in significant populations may alter the natural landscape leading to the decline of native species in favor of invasive.

Conclusions

After analyzing the Transylvanian Plain flora we can say that this region is characterized by a rich and varied flora, with regional particularities and which notes the presence of important species for conservation.

Thus Balkan and Mediterranean species present confers steppic characteristic to the flora of the region.

The presence of the Daco-Balkan and Ponto-Balkanic floristic elements gives a particular aspect of this area, demonstrating the intensity of their differentiation and conservation of tertiary and Pleistocene flora. The presence of some phyto-historical interference in the distant past with the Balkan Peninsula and Anatolia is attested by the presence of the Balkan species.

Due to historical conditioning from the post-glacial period, this territory has a significantly contingent of Mediterranean species.
