Following the three factors category proposed by NatureServe applied on the selected key species we can issue the following conclusions:
1.From the rare species only F.tinnunculus and P. apivorus are listed as in decline species at European level and also at the studied area level
2.Hirundo rustica and Carduelis cannabina are listed as in decline at European level, but at the quarry level they are actually thriving
3.The species listed as rare species, are found in great abundance at the quarry level excepting F.tinnunculus and F.peregrinus presenting a population density survival limit
4.Their local conservation status is stable, even increasing for most of the species but fragile, due to habitat loss
