The results of conservation of plants of the exposition of the calciphilous flora of the Main Botanical Garden of the Russian Academy of Sciences, listed in the regional Red Data Books of Central Russia, are shown. For 12 years, in the culture of GBS RAS, in the conditions of Moscow, 118 calciphilous species listed in the regional Red Books, represented by 77 genera from 34 families, were studied. Among them, in terms of introduction resistance, resistant ones prevail - 46% and highly resistant - 35.5%, weakly resistant - 13.5%, unstable - 5%. The main groups according to ecological confinement are considered: obligate (25%) and facultative (75%) calciphilic species. The experiment proved the importance of using special agricultural techniques for the successful adaptation of representatives of this group. In total, an average of 70% of calciphilous taxa of regional protected lists were tested. The representation of calciphilic species in the regional Red Data Books of Central Russia is different and is due to the natural features of the distribution of their classical habitats. In the regions of the Chernozem region, this figure ranges from 55% in the Belgorod region to 24% in the Tambov region. In the Non-Chernozem region: Bryansk, Ryazan, Tula regions, calciphilic species in relation to the total number of protected species also represent a significant part - 25%. For Vladimir, Ivanovo, Kaluga, Kostroma, Smolensk, Tver, Yaroslavl regions and the federal city of Moscow, calciphilic taxa represent an average of 9% of protected lists. The share of calciphilous species of categories: 0, 1, 2 in the regional Red Data Books of Central Russia averages 58%, which indicates a high vulnerability of this group and the need for ex situ study
