The World Conservation Union (International Union for Nature Conservation) IUCN introduced a classification of threats (IUCN Red list categories, 1994). Extinct and probably extinct taxa may be classified among one of two categories: extinct (EX) or extinct in the wild (EW). A group of taxa at high risk of extinction represents critically endangered (CR), endangered (EN) and vulnerable (VU) categories. Also the lower risk category (LR) has been distinguished, or not threatened (NT). Species, for which it is difficult to determine the degree of threat for lack of adequate information, have temporarily been classified among the data deficient category (DD). The classification of species among particular categories is based on detailed and quantitative criteria (IUCN Red list categories, 1994). Protection of endangered plants is through international agreements. The most important agreement is Convention on the Conservation of European Wildlife and Natural Habitats, adopted in Bern in 1979. This agreement regulates how the protection of wild flora and fauna and their habitats. Another international agreement, concluded between Member States, aims at the identification, designation and conservation of areas that require protection for species and habitats {habitats Directive, adopted in Brussels in 1992-92/43/EEC). Results 12 species were identified, falling into 7 plant associations: MULGEDIO-ACONITETEA Hadac et Klika in Klika 1948 ADENOSTYLETALIA ALLIARIAE Br.-Bl. 1931 Adenostylion alliariae Br.-Bl. 1925 Cirsio waldsteinii — Heracleetum transsilvanici Pawl, et Walas 1949 • Heracleum sphondylium L. subsp. transsilvanicum (Schur) Brummitt (LC) • Campanula patula L. subsp. abietina (Griseb.)
