Ecosystems, habitats and species with community importance: given the altitude and climatic conditions, the vegetation characteristic of the territory is that of the forestwith mountain and subalpine meadows. The deciduous and mixed forests occupy mainly the eastern half of the territory, with average altitudes below 1500 m, consisting predominantly of beech, sometimes associated with maple, hornbeam, fescue, birch and more rarely with the oak, the mountain elm or the black, white or mountain alder. At the upper edge of these forests, the hardwoods appear in combination with spruce or fir. The grassy layer of the forests consists of shrubs, thimble, common fern and earth moss. Around the sheepfold there are the rocks and the stigmata, and in the wetter places grow sedge, hooves and other moisture-loving species. Subalpine pastures are made up of horsetail and blueberries. Habitats protected at European level are in good conservation status and are represented by Luzulo-Fagetum beech forests, Asperulo-Fagetum beech forests, acidic forests of Picea abies in the mountain region, Dacian beech forests Symphyto-Fagion and alluvial forests with Alnus glutinosa and Fraxinus excelsior, the last one being a priority habitat for conservation.

Due to the conditions of relief and geomorphologic conditions, this area is an important wintering, hibernation habitat for the brown bear (Ursus arctos). The other large carnivores with community interest are the wolf (Canis lupus) and bobcat (Lynx lynx). Of the species of bats with community interest, the small lesser horseshoe bat is present (Rhinolophus hipposideros). The species of amphibians are represented by the yellow-bellied toad (Bombina variegata) and the crested newt (Triturus cristatus).
Species of Community Importance
Triturus cristatus (Crested newt) is part of the Triturus genus of the Salamandridae family. It is a vulnerable species in certain areas even endangered. Reducing breeding sites has greatly affected this species, being pretentious than other species of tritons. It lives through the puddles and lakes of the plains to the sub-carpathian area, hidden among the aquatic plant stems. It enters the water in March and, depending on its level, it can stay until May-June. According to the standard sheet, the crested newt is in good conservation status at the Oituz-Ojdula site.
Bombina variegata (Yellow-bellied toad) is part of the Discoglossidae family. Characteristic of this species is the glandular secretion, which is extremely toxic. He lives mostly in standing waters, appearing on the shore in the morning and evening. It is among the first species of amphibians that occupy areas damaged by human activities (deforestation, road construction, etc.) where temporary ponds are formed. According to the standard sheet, the yellow-bellied toad is well conserved in the Oituz-Ojdula site.
Rhinolopus hipposideros, a bat from the rhinolophide family (Rhinolophidae), is the smallest of Rhinolophus species in Romania. It is found in the foothills, missing from the mountain. It lives in caves, abandoned mines, cellars, hollows. In Romania a decrease in its population is evident in recent years, mainly due to the destruction of the habitat, and the development of unorganized tourism. According to the standard sheet, the small horseshoe bat is well conserved in the Oituz-Ojdula site.
The Ursus arctos (Brown Bear) belongs to the Mammalia class, the Carnivora order, the Ursidae family. The brown bear in Romania belongs to the subspecies Ursus arctos arctos. It is a large carnivorous mammal, a plantigrade animal, footmarks can’t be confused with another animal because of their size. Both, the fore and aft legs have 5 fingers. According to the standard sheet, the bear is in good conservation status at the Oituz-Ojdula site.
The Canis lupus species (Wolf) belongs to the Mammalia class, the Carnivora order, the Canidae family. The wolf in Romania belongs to the subspecies Canis lupus lupus. It is a carnivorous mammal, a monogamous species, the pairs are formed from December to February when pairing takes place. The most developed senses are vision and hearing, but the smell is well developed. According to the standard sheet, the wolf is in good conservation status at the Oituz-Ojdula site.
The species Lynx lynx (Bobcat) belongs to the Mammalia class, the Carnivora order, the Felidae family. The bobcat in Romania belongs to Lynx lynx lynx subspecies. When he is scared or attacked, he puffs his opponent and growls like a cat, while pairing meows similar to cats. The most developed senses are vision and hearing.
