Although a quarry is represented by industrial activities, being it self an ecosystem with specific environmental factors values, it is not separated by the surrounding ecosystems. As the species know no borders,  between the quarry and the surroundings exists connective "green"channels.  This channels are used by key species for  supply and energy exchange between the quarry and the surroundings. The key species could be represented by flora and fauna equally. In order to be sustainable a quarry management needs to maintain this connections at optimal levels. Therefore, there are three steps to follow: 1.  An inventory of the key species present at the quarry level and in the surroundings. 2. The conservation status assessment of the key species. 3. Adopting a set of measures in order to increase the conservation status of the identified key species . Following this three steps will bring a real visibility over the quarry ecosystem functioning in connection with natural habitats.
