Mining activity was known and practised worldwide since ancient times. Human impact exerted in a mining career on biodiversity is smaller or greater and it depends on many factors. Mining environment issues require a systematic approach and sustainable environmental management techniques must be applied correctly in the mining areas around the world. It is that strategic principles and elements for ensuring sustainable development in a mining career were set. For a good ecological rehabilitation in a mining quarry we need first to know the biodiversity existing in that area in all its complexity, including the sub-layer on which it grows. For a good ecological ingrowths in a mining quarry, or any other mining quarry, it is necessary as V. Cistea recommended (1993) to take into consideration the mediogene and control functions of phytocoenoses which ensure ecological ingrowths through: humane relief set, pedogenesis control and soil protection, microclimate control, fluid control, reducing runoff, depth erosion (landslides, ravines, basins), alleviation etc. The study and knowledge about the vegetation and cormoflora biodiversity in Bicaz Chei area, whose vegetating cover goes through profound changes due to anthropo-zoogen factors existing in that area, answer to a necessity of great interest (M. Niculescu, 2014).
