Other Site Characteristics

Site " Devnenski halmove" consists of seven hills located in the surroundings of Devnya town and the nearby villages Chernevo and Padina. The hills are Ostria hill (Sivri tepe) northeast of Devnia (in the land of Chernevo village); Dalgata mogila hill east of Devnia; Harman Kaya north of Povelyanovo; a small hill east of Povelyanovo and a series of hills near Padina village, the highest of which is Golemia Sakar. Of these, Ostria hill is in the land of Suvorovo municipality and the rest are in the land of Devnya municipality. On the slopes of the hills there are significant distinct revelations of Lower and Upper Cretaceous limestones, with a variety of marl, marly clays, calcareous sandstones and harder, organogenic limestones. The hills have plateau top area and slopes with different inclination and exposure, as the revelations are mostly on the southern slopes. Parts of the hills are ancient land of Cretaceous age and precisely this is at the bottom of the presence of relict steppe herbaceous vegetation. Soils are predominantly rendzinas, very shallow, skeletal in the areas of the revelations. On all of the hills has developed woody and shrub vegetation, bushes of hawthorn, lilac, thorny bush, wild privet, wild jasmine (Crataegus monogyna, Paliurus spina-christi, Syringa vulgaris, Ligustrum vulgare, Jasminum fruticans) and others, as well as low-growing oak-oriental hornbeam groves (Quercus pubescens, Carpinus orientalis), with the participation of nettle tree (Celtis australis), flowering ash (Fraxinus ornus) and others.

4.2 Quality and importance

The site conserves areas of primary Pontic steppe vegetation in the alliances Agropyro-Kochion, Festucion valesiacae, Stipion lessingianae, Pimpinello-Thymion zygioidi, with significant diversity in the communities with rich in steppe elements flora as some species are relicts with local distribution in the Pontic region. (Hieracium virrosum, Centaurea marshalliana etc.) and presence of local and regional endemics (Verbascum tzar-borisii, Centaurea caliacrae). The individual hills have certain differences, in the presence of different rare species, as well as the presence / absence of dominant species of the plant communities. The wormwoods typical of the Western Pontic wormwood steppes, form communities on the Ostria hill and the hill Dalgata mogila; Forage kochia (Kochia prostrata) on the slopes of the hills around Padina village, and on the southern slope of Harman Kaya Jurinea stoechadifolia is one of the dominant species. The following typical of the habitat species are also present: Galium volhynicum, Tanacetum millefolium, Acillea clypeolata, Rhodax canus, Ruta graveolens, Koeleria brevis, Chamaecyrisus jankae, Centaurea caliacrae, Inula oculus-christi, Iris pumilla, Convolvolus cantabricus, Gypsophilla glomerata, Euphorbia nicaensis ssp. candilathri, Scutellaria orientalis, Adonis flammea, Potentilla bornmuellerii, Euphorbia mirsynites, Helianthemum salicifolia. There are also Phlomis tuberosa, Phlomis herba-ventii, Cephalaria lucida, Centaurea stereophylla; Cleistogenes bulgarica, Campanula sibirica, Serratula radiata, Mathiolla fruticolosa, Centaurea marshaliana, Hieracium virrosum and others. Detailed floristic and phytosociological studies will justify even more undeniably the high assessment given to the value of the hills as relict habitats.
