Natural area „Pajiştea Gura Oituz” (P.G.O.) consists of 15 ha protected by State according to the Law of Natural Area Fund and 22.41 ha, after 2014 reevaluation, is placed on meadow of Solonet river Soloneţ, affluent of Răut River. It is subordinate to the Cotiujenii-mici mayoralty (village GuraOituz), Sângerei district. P.G.O. has the following coordinates: longitude of 28.363406, 28.358201, 28.345448, 28.345719 latitude of 47.705769, 47.702504, 47.697913, 47.700652. Protected area is contained in Ecological Legislation of the Republic of Moldova, Decision nr. 1538-XIII dd 25.02.1998 in chapter “Areas with multifunctional management” [1].  The actual protected area represents a primary meadow, intensively grazed, with predominance of field grass (Agrostis gigantea and A. stolonifera). It has been attested the presence of 33 species of vascular plants, out of which, the most rare are pratoformants – Poa pratensis Alopecurus pratensis, Beckmannia eruciformis [2]. P.G.O. contains the following species: Agrostis stolonifera, Agrostis gigantea, Poa pratensis, Alopecurus pratensis, Beckmannia eruciformis, Festuca gigantea, Carex otrubae, Carex distans, Ranunculus acer, Taraxacum officinale, Elytrigia repens, Lolium perenne, Plantago media, Potentilla repens, Rumex sanguineum, Medicago falcata, and also swampy habitat species: Bolboschoemus maritimus, Scirpus tabernaemontani, Carex riparia, Tipha latifolia, Tipha angustifolia, Butumus umbelatus, Scirpus lacustris, Phragmites australis, Potentilla anserina, as well as salty resorts species: Puccinellia distans, Juncus gerardii, Lotus corniculatus, Leontodon autumnalis and some weedy resorts species: Xanthium strumarium, Achillea neilreichii, Cichorium intybus, Leontodon autumnalis, Plantago lanceolata, Cardaria draba, Senecio vernalis, Capsella bursa-pastoris, Lepidium ruderale, Arctium lappa. Threatened species are pratoformants – Agrostis stolonifera, Poa pratensis, Alopecurus pratensis, Beckmannia eruciformis, which are physically and ecologically damaged under grazing conditions and are stimulated by intensifying process of habitat xerophytization. Associative character is expressed by grass communities of ass. Agrostetum stoloniferae Ujvaroşi 1941; and Poetum pratensis Răvăruţ, Cazak, Turenschi, 1956 with associations of Beckmanietum and Alopecurietum [2]. Natural protected area „Gura-Oituz”  It is threatened by establishment of Danubian-Pontic habitat and species with Nordic area Agrostis stolonifera, Poa pratense, Festuca pratensis, Alopecurus pratensis. Causes of habitat degradation are expressed through unlimited and spontaneous grazing.
