Dynamics of the demographic structure and variability of some morphological parameters of Calophaca wolgarica (Fabaceae) during reintroduction to the Saratov region

Preliminary results of studies on the reintroduction of Calophaca wolgarica to the territory of the Saratov region are presented. In the period from 2018 to 2020, the age structure of artificial plantings and changes in the morphological parameters of individuals within them were studied. It is shown that on the territory of the Saratov region, artificial plantings of this species are best located near the protected area “Tulip Steppe near the village of Maksyutovo”.
