Andreea Natalia MATEI

Ellenberg indices for light, temperature, humidity, soil reaction and available nitrogen [7], [6], [18] were taken into account for the studied plant association. Also Ellenberg indices analysis had led to a more accurate description of the habitat in which is included the association.

Phytosociologycal surveys used for species inventory were conducted following the methodology developed by Zürich-Montpellier phytosociology school adapted to Romanian vegetation by Al. Borza. The habitat codes used in the present paper correspond to: NATURA 2000, Romanian classification system (EUNIS), and Carpathians Red List of habitats.

Results and discussions

1. Taxonomic analysis

Therefore from the taxonomic analysis conducted on Cirsio waldsteinii-Heracleetum transsilvanici Pawl, et Walas 1949 association, resulted 110 taxa included in 45 families. The families with the largest percentage are held by: Asteraceae (19%), Rosaceae (7.2%), Ranunculaceae (6.3%), Poaceae (5.4%) and Apiaceae (4.54%). (Fig. 2) (Tab. 1.). As a result the plant association is characterized by a signifficant diversity of plant taxa.

2. Bioforms analysis

From bioforms spectrum analysis of Cirsio waldsteinii-Heracleetum transsilvanici Pawl, et Walas 1949 association, it can be noticed that hemicryptophytes species are holding the largest share (69%), being followed by the rest of the bioforms with a smaller percentage, such as: geophytes (12%), megafanerophytes (5%) and microfanerophytes (4%). (Fig. 3).
