The first part of the inventory of forest habitats in the Oituz-Ojdula Natura 2000 site was completed, as part of the “Elaboration of the Natura 2000 Oituz-Ojdula Management Plan” project.
The Oituz-Ojdula Natura 2000 site (situated in the Breţcu Mountains) is a territory with forest habitats such as beech, spruce and alder forests. Beech forests meet along the valleys of Oituz and Ojdula. Here we find species characteristic of montane and submontane beech forests, such as woodruff (Asperula odorata), wood anemone (Anemone nemorosa), wood spurge (Euphorbia amygdaloides), Solomon’s-seal (Polygonatum verticillatum), wood speedwell (Veronica montana), cardamine glanduligera (Dentaria glandulosa), roadside fescue (Festuca drymeja), white butterbur (Petasites albus).
In acidophilic sites, often in recesses, with percolated soil, acidophilous species of beech forests appear in the grassy layer, for example wood bluegrass (Poa nemoralis), white wood-rush (Luzula luzuloides), reedgrass (Calamagrostis arundinacea), wood-sorrel (Oxalis acetosella) were found. Acidic species really appear primarily on the edge of forests, mountain pastures, or spruce forests. Of these, we have the European blueberry (Vaccinium myrtillus), the lingonberry (Vaccinium vitis-idaea), the common heather (Calluna vulgaris), the Stag’s-horn clubmoss (Lycopodium clavatum) and the northern firmoss (Huperzia selago).
Plants specific to the Dacian woods of beech are the common comfrey (Symphytum cordatum) and the red lungwort (Pulmonaria rubra), found along the streams, but also spread throughout the territory.
Dacian beech forests occupy larger areas, however, there are only a few species-rich spots. Here one may find the long beech fern (Phegopteris connectilis), enchanter’s nightshade (Circaea alpina), February daphne (Daphne mezereum), ghost orchid (Epipogium aphyllum).
In the beech forests we also find plants specific to hot and dry areas, such as wood melic (Melica uniflora), yellow foxglov (Digitalis grandiflora), and black pea (Lathyrus niger).
The grassy layer of spruce forests resembles beech woods, but in the absence of light, there are several acidophilous species, such as the ne-flowered wintergreen (Moneses uniflora) and sidebells wintergreen (Orthilia secunda).
Of all types of forests the richest and most interesting in species are the alder, near the brooks. These forests are made of gray alder (Alnus incana), interesting fact that the gray alder is present up to the edge of the Natura 2000 site, on the Ojdula side. Outside the site appears the black alder. Besides the species characteristic of these forests – such as the heartleaf oxeye (Telekia speciosa), white hellebore (Veratrum album), valerian (Valeriana simplicifolia), the large bitter-cress (Cardamine amara), ostrich fern (Matteuccia struthiopteris) – more rare species occur, the giant bellflower (Campanula latifolia), the broomrape (Orobanche flava), the parasite of butterbur (Petasites hybridus).
In the Oituz Valley there are extensive meadows (after deforestation), some are drier and some of them are humid, and there are a large number of different species: the european globeflower (Trollius europaeus), the sneezeweed (Achillea ptarmica), and the sedge species (Carex canescens, Carex echinata, Carex nigra and Carex rostrata).
|At the edge of the forests there are dispersed swamps with the species characteristic of these habitats, which are not found in other parts of the site: common mouse-ear chickweed (Cerastium sylvaticum), wood horsetail (Equisetum sylvaticum), common cottongrass (Eriophorum angustifolium), flat-sedge (Blysmus compressus), ragwort (Senecio subalpinus).
On mountain pastures we can find the matgrass (Nardus stricta), but in the more grazing places we find the bentgrass (Agrostis spp.). Another plant specific to the meadows and forest edges is the Peucedanum oreoselinum, which marks a sandy soil.
In places where rocks appear, in the beech forests and in the ditches appear plants as common polypody (Polypodium vulgare) and other fern species.
In habitats with forests and lawns, allogeneic species do not have the necessary conditions to grow, however, along the roads they may appear in a smaller number, for example slender rush (Juncus tenuis), gallant soldier (Galinsoga parviflora), shaggy soldier (Galinsoga quadriradiata), seaberry (Hippophae rhamnoides), and even near the national road black locust (Robinia pseudacacia).
There are currently 460 vascular plants, but ongoing botanical analyzes will certainly increase this number.
