Introduction Current grassland terrains in R. Moldova represents degraded pastures having a forage mass productivity of 3-4 ct/ha, reduced fl oristic composition and a phitocenotic organization with deviation from normal conditions of soil and climate Material and methods By completely excluding anthropogenic infl uence on degraded meadows terrains take place fl oristic and phitocenotic restoration in the ecosystem until the dynamic balance formation with key environmental factors (humidity, temperature, trophicity, soil chemical reaction, type of phreatic salinization). Results and discussions During the last 30-40 year have been restores vegetation of the calcifi ed grassland meadow of the river Valea Crucii (right tributary of the river Bâc, fl owing through the territory of Botanic Garden of the Academy of Science of Moldova). On the areas with groundwater depth of 0.5-1 m have been restored phitocenosis with smooth-stalked meadowgrass (Poa pratensis L.), those with 1-2 m depth orchard grass (Dactylis glomerata L.), those with 2-3 m – oatgrass (Arrhenatherum elatius L.), and those superfi cial (below 0.5 m) – reed (Phragmites australis (Cav.) Trin. ex Steud.). Renaturalization of the marshy meadow with calcifi ed habitat have occured on right bank of the river Bâc which is under protection since 2002 by „Association of hunters and fi shermans” (town of Straseni). In the meadow of river Bâc (town Straseni) with phreatic calcifi ed overgrazed and degraded grassland have been renaturalized by restoring and preserving the fl oodplain inundation regime. Shallow groundwater stimulates expansion of phitocenosis Phragmitio-Magnocaricetea Klika 1941 on the entire protected area. Conclusions Renaturalization of calcifi ed degraded meadows by optimizing grazing regime or stop by and use them as hay would boost productivity and enhance forage mass and its nutritive value and rehabilitation of all ecological parameters of the ecosystem, that can assure stability in functional meadows.
