THE DISTRIBUTION AND STRUCTURE OF THE FOREST NATURA 2000 HABITATS FOUND IN THE SANATORIU AND ARSANCA FORESTS OF THE GOVORA RIVER BASIN

Abstract

The thematic area  provided in this paper is situated in the Govora river basin, Vâlcea County. Within this study had been aimed the identification, description, diversity, ecological analysis and monitoring of the herbaceos and wooden plant communities, which belong to the Natura 2000 habitats and implicitly of the rare plant species, vulnerable, endemic whitin Sanatoriu and Arsanca Forest from the Govora river basin. In this area we identified the following plant communities: Quercetum petraeae-cerris Sóo (1957) 1969; Carpino-Fagetum  (sylvaticae) Paucă 1941; Scirpetum sylvatici Ralski 1931 emend. Schwich 1944; Petasitetum albae Dihoru 1975; Botriochloetum ischaemi (Kristiansen 1937) Pop 1977, Agrostietum stoloniferae (Ujvárosi 1941) Burduja et al. 1956; Calamagrostetum epigei Juraszek 1928. According to the targets of this research, a very important place we gave to the complex studies of the habitats: 91M0 Pannonian-Balkanic turkey oak sessile oak forests, 9170 Galio-Carpinetum oak-hornbeam forests; 91E0*Alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae) ; 6430 Hydrophilous tall-herb fringe communities of plains and of the montane to alpine levels; 6440 Alluvial meadows of river valleys of the Cnidion dubii; 6240*Sub-pannonic steppic grasslands; 3150 Natural eutrophic lakes with Magnopotamion or Hydrocharition-type vegetation; 3160 Natural Dystrophic Lakes and Ponds (Gafta and Mountford coord, 2008). Considering the place where the studies had been located to, the  eco-pedo-climatic conditions and the anthropic term exerted we have considered that is necessary to develop some ecological studies for the plants communities for this habitats from this area
