In the year 2014, succession of plants, spiders and other invertebrates was studied in the middle and on the border of the quarry as well as on the rocks. Sites with dense and sparse vegetation cover were examined in the first two biotopes. In total, 77 plant, 102 spider, seven diplopod, three isopod, two harvestman and two pseudoscorpion species were found. Among the spider species, 20 of them were newly discovered in the quarry and 21 of them were of significant ecological importance. This number confirms that limestone quarries are important as a refuge for rare species whose habitats are disappearing from our country. The most important finding, beside that of Pardosa wagleri, is Pseudomaro aenigmaticus. In the case of the latter species, it is the third record in the Czech Republic.

In 2013, population density of critically endangered wolf spider Pardosa wagleri was charted and two localities at the northern parts of the quarry of {\v C}ertovy schody \– West was investigated. Population of P. wagleri is relatively rich and occurs along the whole western, north-western and south-western margin of the bottom of the quarry. The spiders inhabit namely moist cavities under stones. A humid depression hosts an indifferent arachnofauna. Thus, a small lake planned at this place will not negatively affect the spider population. In addition, biodiversity will be enriched by hygrophilous species. Despite rare and endangered species are currently present, technical reclamation is wasting of natural potential because these rare and endangered species have no chance to survive. Therefore, natural succession has to be preferred to technical reclamation. This approach will result in development of mosaic landscape with sparse vegetation. Technical reclamation (namely planting coniferous monocultures) is disadvantageous due to its high costs and because it decreases biodiversity.
