5. South-Eastern Carpathians Grasslands with Agrostis tenuis and Festuca rubra

Widespread habitat with a moderate conservative value which can be high in the Central Trascau Mountains when Trollius europaeus and Narcissus stellaris or both are abundantly present (as here are most of the cases)

Romania – R3803

Natura 2000 – 6510 Lowland hay meadows (Alopecurus pratensis, Sanguisorba officinalis). Improper classification. Should be subjected to major revision.

Palearctic 1999 38.2323 Eastern Carpathian Yellow Oat Grass meadows

Eunis E1. 721 Nemoral Agrostis-Festuca grasslands

Emerald 37.2 Eutrophic humid grasslands.

(coded in our releves tables as AFR and AF)

 

6. Danubian-Pontic grasslands with Poa pratensis, Festuca pratensis, Alopecurus pratensis

Widespread mesophile habitat in the whole south-eastern Europe but with a very peculiar and special composition in Piatra Cetii natural reservation where it is encountered right at the top of the stones, on the peak where totally unexpected mesohygrophile conditions were encountered. The result is a very strange combination of calciphile and mesohygrophyle species that was never seen before by us.

Romania – R 3716

Natura 2000 – 6440 Alluvial meadows of river valleys of the Cnidion dubii.

Palearctic 1999 – 37.263 Danubio-Pannonic riverine and humid meadows

Calcareous rocks and screes

 

7. South-Eastern Carpathian communities on calcareous rocks with Asplenium trichomanes quadrivalens and Poa nemoralis

Widespread but reduced ecotone habitat placed at the limit between the forest and the open rocks or screes or on the steep shaded rocky walls or screes placed right above the beech forests.

Romania – R6209

Natura 2000 –

Palearctic 1999 – 62. Inlands cliffs and exposed rocks

8. South-Eastern Carpathian communities from calcareous rocks fissures with Asplenium trichomanes and Asplenium ruta-muraria

Very frequent on steep calcareous slopes and boulders and also on primarily fixed screes

Scrubs

Phytotaxonomy Corno-Fraxinetum orni Pop et Hodisan 1964.

 

10. South-Eastern Carpathian scrubs with Spiraea ulmifolia

Regional sub-endemic habitat of a high conservative value. While it is the main kind of scrub encountered in the Apuseni Mountains on calcareous rocks with Spiraea ulmifolia as a dominant, in the particular case of Piatra Cetii massif in most cases the Black Rose Rosa spinosissima assumes the dominance while Spiraea is totally subordinated. Thing are completely reversed in the other calcareous massifs from the region.

Romania – R 3116

Natura 2000 – 40A0*. Sub-continental Peri-Pannonic scrub.

Palearctic 1999 – 31.8B 142. Carpathian Elm – Leaved Spiraea thickets.

(Coded in our releves tables as SU).

 

11. South-Eastern Carpathian thickets with Hazel Corylus avellana and Spiraea ulmifolia

Habitat of interference (ecotone) between the beech forests and Spiraea scrub from the calcareous rocks; hard to say if they are of a natural or a human nature – probably both. Scattered Ash trees (Fraxinus excelsior) and Mountain Maples (Acer pseudoplatanus) complete the landscape without making a forestry habitat.
