Ovidius University Annals of Natural Sciences, Biology – Ecology Series Volume 14, 2010 PRELIMINARY DATA ON MELEDIC – MANZALESTI NATURAL RESERVE (BUZAU COUNTY, ROMANIA) Daciana SAVA *, Mariana ARCUŞ**, Elena DOROFTEI * *Ovidius University, Natural Sciences Faculty, Aleea Universitatii No. 1, corp B, Constanţa, 900470, Romania, e-mail: daciana.sava@gmail.com ** Ovidius University, Faculty of Pharmacy, Aleea Universitatii No. 1, corp B, Constanţa, 900470, Romania __________________________________________________________________________________________ Abstract: the Meledic –Manzalesti Reserve is situated in the central-eastern part of Romania, in Buzau County, 60km north form town of Buzau. The Reserve (136 hectares) is delimitated by four rivers and it is situated at a medium altitude of 530 m. Because of the remarkable forms of relief, appeared as a result of dissolution of salt, the presence of a salt cave unique in Europe and of a number of lakes with fresh water, this area was declared in 1986 Geological and Speological Reserve. Later (in 2000) due to the presence of an interesting flora and fauna it was established the value of its natural heritage, and was declared as „Protected Natural Area” with geological, speological, floral and faunistic importance. In 2007 it was declared „Site of Community Importance” and will become area of special conservation after the validation of the European Commission. The present study took place over a period of two years, with field trips in various periods of the year. As for the flora, taxons belonging to over 100 genera were identified, Most genera belong to Fabaceae, Asteraceae, Labiatae, Rosaceae and Umbelliferae families. The statistical analysis showed as biological forms, the predominance of hemicrytophytes. As floristic elements, the Euro-Asiatic and Central European elements predominated. As regarding the ecological preferences (humidity, temperature and soil reaction) it has been observed the domination of xeromesophytic, mezothermal and euriionical species. Keywords: Natural Reserve, Manzalesti –Meledic Natural Reserve, Romania __________________________________________________________________________________________ 1. Introduction In 1978, a group of Romanian spelologists, part of “Emil Racoviţã” Speologists Club from Bucharest, discover in the sub-Carpathians Mountains at Mânzãleşti, the longest (300 m), the deepest (44 m) and the most ramificated cavity in salt in the country, second in the world as oscillation of level, third as length, wich they named “The cave with three entrances“ from Sãreni. In 1980 the “6s“ Cave from Mânzãleşti is discovered, the longest cave in salt world-wide at that moment (1257 m) and the second as oscillation of level (-32 m), with numerous ramifications. Later on, other galleries, were discovered of a total of 4257 m length, 32 caves digged in salt, taking the Mânzãleşti cave to the second place in the world for caves digged in carst of salt. Later on, in 1986, the salt carst from Mânzãleşti becomes a reserve of The Romanian Academy from the geological and speleological point of view. According to the Habitat Directive 92/43/CEE concerning the conservation of natural habitats, wild flora and fauna, the protected areas network Natura 2000 appears in România, which includes also in this network the Meledic Plateau of Mãnzãleşti commune, Buzãu County, according to Law nr 5/5 March 2000 [1]. The site has the ROSCI 0199 code and is classified under category IV (according to UICN) as Special Conservation Area. The reserve is part of the Continental Biogeographical Region; its existance is trying to protect the “Ponto-sarmatic deciduous thickets” habitats.
