Ass. Thymo pannoniéi - Stipetum stenophyllae Sanda et al 1998 The coenoses of this association (Table 2) settle on limited surface areas, situated in the upper third of the western hill slope, at an altitude of 400 m s.m, with 20° inclination. The association has also been reported in the Transylvanian Plain, the surrounding areas of Blaj, Sebesului Valley, Gusteritei Valley, and Secaselor Plateau. The steppe landscape is dominated by xeric grasslands, in the composition of which gramineae and various xerophilic dicotyledons are prevalent. The 62 species of the floristic composition have a 90% coverage. Along with the dominant species, Stipa stenophylla and Thymuspannonicus, the floristic composition includes a great number of xerophilic species characteristic of Cirsio-Brachypodion, Festucetalia rupicolae, Festucetalia valesiacae, but the species characteristic of the Festuco-Brometea class are also well represented, which enhances the xerophilic character of the association. Microthermal Prunus tenella and Rosa gallica bushes are also found within the association. Several species of the Molinio-Arrhenatheretea class have also penetrated the coenoses. The spectrum of ecological indices (Fig. 5) evidences the great number of xero-mesophilic (64.51%), xerophilic (16.12%) and 14.51% mesophilic species. In relation to temperature, the species are predominantly micro-mesothermal (40.32%), moderately thermophilic (35.48%), followed by eurythermal species (17.74%). Regarding the soil reaction, the majority of the species are weakly acid-neutrophilic (54.83%), euryionic (20.96%), acid-neutrophilic (19.35%), and 3.22 are neutro-basophilic species. 14
