The site Natura 2000 ROSCI0226 Semenic-Cheile Carașului has been confirmed as a site of community importance in 2008, thereby contributing to the development of the network Natura 2000 in Romania. The site surface hosts types of natural habitats of national interest whose conservation require naming these areas and species, enumerated within annex II of Habitats Directive 92/43/CCE, as special. The aim of this paper is to maintain a favourable preservation state of species and habitats in the studied area, by proposing some general measures of improvement and conservation, but also by using special measurements for grassland habitats and shrubbery protected by community law. Our studies were carried out on the area of the administrative territory of Goruia, Caraș-Severin county, Romania, on grasslands situated on the hilly area – nemoral, totally or partially overlapping the site Natura 2000 ROSCI0226 Semenic – Cheile Carașului. Research is based on literature supplemented with data collected in the field. In the grasslands from U.A.T. Goruia, overlapping the site Natura 2000 - ROSCI0226 Semenic – Cheile Carașului, some habitats of community interest have been identified, such as: habitat 6210*, 6410, 6510, 6190, 5130. The permanent grassland analysed in our study are diverse in terms of flora, through specific methods of analysing the flora and the vegetation (phytosociological, linear, pratological). Based on station conditions, but also on the way these are managed, the following types of grasslands are encountered: mesophile, mesoxerophile and mesohigrophile. Through a complex analysis, abiotic factors have been identified and the human influence on the operating mode of the grasslands, therefore conservation and improvement measures have been proposed. The most important limiting factors identified in the meadows of the U.A.T. Goruia are: the presence of harmful species, soil erosion, land subsidence and fragmentation, heavy soil or soil water retaining proliferation acid indicator species, the parent rock to the surface, the absence of minimal maintenance work, grazing inefficiently (overgrazing or undergrazing).
