Abstract

The census of Listera was conducted on routes with a total length of 11.05 km on 2020. The width of the recording transect was 10 m. In suitable habitats, plants were located in relatively dense groups, separated from each other by considerable distances. We have revealed 31 subpopulations of Listera with a total of 283 generative shoots and 1949 vegetative ones. The density of Listera in the surveyed habitats was 3.50 ind./ha, density in the subpopulations was from 5 to 13 ind./sq.m, on the average 6.81 ind./sq.m. All the Subpopulations were confined to areas of moss cover dominated by sphagnum mosses, but with the obligatory presence of Polytrichum commune and hypnum mosses. The setting and ripening of Listera fruits in 2020 were high: fruits were developed from 84% of flowers. The Tulashor site of the Nurgush State Nature Reserve plays an important role for the conservation of Listera cordata in the Kirov region.
