ABSTRACT
Association Anthoxantho-Agrostietum capillaris Sillinger (1933) [22], is now reported for the first time in Lăzăreni Hills. This study aims to analyze the phytocoenoses of the Association Anthoxantho- grostietum capillaris (Class Molinio-Arrhenatheretea Tüxen 1937) from phytocoenologic, floristic and economic points of view. Phytocoenoses association analysis present a scientific importance, with a total of 107 species, which is a very rich biodiversity, some species are rare, vulnerable, endemic and need to be protected. Meadows with Anthoxanthum odoratum and Agrostis capillaris is an important forage for both livestock grazing and harvesting land-mass hay. Meadows give this association a great phytomass production, but with low economic value. Because of human low biodiversity, flora and vegetation of these meadows have a natural character. Grassland maintain stable equilibrium and the ungrassed bush tend to phytocoenoses progress (Pruno spinosae – Crataegetum (Soó 1927) Hueck 1931).
