| Title : | IN-SITU AND EX-SITU CONSERVATION OF PONTECHIUM MACULATUM (L.) BÖHLE ET HILGER (BORAGINACEAE) IN REPUBLIC OF MOLDOVA |
| Abstract : | This study presents the results of the in-situ and ex-situ activities aimed at the effective protection of Pontechium maculatum (L.) Böhle et Hilger (= Echium russicum J. F. Gmelin) populations, the vascular plant species of community interest growing in the spontaneous flora of the Republic of Moldova, but which is in danger of extinction. The habitat of the species Pontechium maculatum includes xerothermic meadows, petrified slopes with calcareous substrate but also thermophilic forest glades with downy oak. The decrease in the number of populations and the disappearance from the natural sites is most likely caused by the degradation of specific habitats by changing the structure of xerothermal meadows: increasing their density, forming a compact layer of dead plants, preventing the development of seedlings, but also the excessive growth of shrubs in the glades of downy oak forests. Other threats, which contributed to the disappearance of many populations of Pontechium maculatum, are the afforestation of grasslands and steppe slopes and the overgrazing of specific habitats. We estimate that the population in the "Bugeac multifunctional management area", in the south of the republic, has high potential for conservation actions, this being the "mother population" from which seeds were collected at the beginning of the project and seedlings were obtained, with the aim of later repatriation into the natural habitats. The main activities carried out within the project were the identification of two natural habitats to which plants, obtained in ex-situ conditions, were transplanted. At the same time, an ex-situ plant collection was created within the "Alexandru Ciubotaru" National Botanical Garden (Institute). |
