The objective of this study was to perform the hierarchization procedure of habitat physical-chemical properties of peat bog waters in a five-year research cycle. The identification of important abiotic habitat properties in the context of the analyzed boreal plant relics’ occurrence determines the mechanisms of their active protection, and in the case of useful plants with high medicinal values – the possibility of their ecological cultivation. The procedure covers desk studies involving source data analysis, field reconnaissance with selection of study sites, botanical-phytosociological analyses, and laboratory analyses of the abiotic properties of the habitat. The complex statistical analysis of the obtained data including descriptive statistics, non-parametric Kruskal-Wallis test, and multidimensional methods permitted the designation of range values for properties favoring the occurrence of the studied plant species. The procedure finds practical applications for both for the active protection of endangered plant species and other useful plants.
