Plants along with other components of living nature, are considered as the national wealth that requires conservation, enrichment and rational use. It should be emphasized that in this respect, species of wild flora deserve priority attention, since they are the most vulnerable group of plants. The threat of extinction of wild flora plants and their habitats is rapidly increasing all over the world. It is known that in situ conservation of plant communities and selected species is preferable to ex situ conservation. However, the scale of destruction of biocenoses in many regions often leaves no room for plant conservation in natural conditions. In this regard, the reintroduction of individual species into preserved natural areas, and in the future the restoration and reconstruction of entire communities, should be considered as promising measures to save endangered plants. This problem is especially relevant for the Republic of Moldova, which territory is subject to a strong anthropogenic pressure, due to outdated technologies and equipment that have seriously aggravated the ecological situation. Biodiversity conservation problems come to priority for modern plant biology. Due to the destruction of natural habitats of rare species, as the leading positions for their protection come ex situ methods. Along with the introduction to botanical gardens, there should be the experience of reintroduction of rare species in natural habitats, in natural communities with similar ecological conditions for these species [19]. The aim of this work is to investigate the state of existing natural population of Critically Endangered [8, 9, 12] vascular plant in the Republic of Moldova – Digitalis lanata Ehrh.
