ARTIFICIAL CENOPOPULATIONS OF RARE AND ENDANGERED BELАRUSIAN FLORA SPECIES IN THE CENTRAL BOTANICAL GARDEN OF NAS OF BELARUS

The results of inventory of artificial cenopopulations of rare plants of natural flora in the conditions of the Central Botanical Garden of the National Academy of Sciences of Belarus (CBG) are presented. 24 artificial and 2 spontaneous cenopopulations of 16 plant species were inventoried and mapped on CBG territory. All cenopopulations were classified into 4 groups: successfully naturalized and invasive developing (п = 9 cenopopulations), inferior cenopopulations under anthropogenic exposure (п = 7), newly created cenopopulations (п = 8) and spontaneous cenopopulations (п = 2). 6 cenopopulations of Astrantia major L. (п = 3), Drymocallis rupestris (L.) Sojk (п = 1), Iris aphylla L. (п = 1), Vicia pisiformis L. (п = 1) are belonging to the category of critically endangered species (CR). 3 cenopopulations of Clematis recta L. (п = 1) иand Hedera helix L. (п = 2) are belonging to the category of endangered species (EN). 5 cenopopulations of Allium ursinum L. (п = 2), Aruncus dioicus (Walter) Fernald (п = 2), Pulmonaria mollis Wulfen ex Hornem. (п = 1) are belonging to the category of vulnerable species (VU). 6 cenopopulations of Campanula latifolia L. (п = 1), Iris sibirica L. (п = 1), Lilium martagon L. (п = 1), Lunaria rediviva L. (п = 3) are belonging to the category of near threatened species (NT). The cenopopulations of Digitalis grandiflora Mill. (п = 1), Geranium phaeum L. (п = 1), Epipactis helleborine (L.) Crantz (п = 1), Hepatica nobilis Mill. (п = 1), Matteuccia struthiopteris (L.) Tod. (1), Tulipa sylvestris L. (п = 2) are categorised as conservation dependent species (CD). Ontogenetic spectra of cenopopulations studied were constructed and development stages of their groups and vital strategy peculiarity were detected. Individual vitality index (IVI) was estimated based on morphological characteristics of individual plants composing cenopopulations. Vitality of all artificial cenopopulations entered into natural phytocenosis was identified as prosper type. Two cenopopulations were assessed to have depressive vitality type.
