New location of Nitraria sibirica Pallas in Buryatia

A new location of the rare relict species Nitraria sibirica Pallas was found in Buryatia. The work provides geobotanical descriptions of the community with the participation of this species. It was found that the population is invasive in nature, with a predominance spicimens of pregenerative and early generative age, with successful fruit formation. The increase in the number of individuals of N. sibirica is linked with the expansion of its environmental niche, which in turn is due to a drop in the level of groundwater and an increase in the salinity of the habitat in previous dry periods.
