Abstract:
The research of rare species is included both in the stipulations of national laws and strategies, as well as in the international obligations of the Republic of Moldova, and the protection of threatened species under in-situ conditions is a priority objective, included in the Biodiversity Conservation Strategies. Thus, the limiting factors can be quickly identified and urgent and effective measures taken to stop the decline of populations of species threatened with extinction and their conservation. The present study refers to Epipactis palustris (L.) Crantz (Orchidaceae family), critically endangered species, protected by law, included in the Red Book of the Republic of Moldova.
