Caucasian subalpine tall grass communities are noted for an exceptional species<br />

diversity - 90 species, more than 50 of them can be found in the reserve. These<br />

communities contain predominantly Umbelliferae and Compositae families, less<br />

frequently cereals (cowparsnip, multiflowered companula, ragwort, heart-leaved<br />

oxeye, Kuprianov's rye, etc.)<br />

4.5.2.1.2 Vegetation<br />

Aquatic plants in high mountain lakes of the reserve contain only 7 species; all of<br />

them are boreal (lesser duckweed, spring starwort, spiral wild celery, etc.). The<br />

boundary of their growth is 2400 m. The total number of marsh species is 41.<br />

The greater part of them (65%) pertain to the Cyperaceae and Juncaciae families.<br />

Florogenetically, this group is rather uniform: 85% of its species have a boreal<br />

form of areas. Some marsh species are relicts of the Pleistocene period (mud<br />

sedge, sheathing cotton grass, marsh cinquefoil, small gentian, etc.). Most of the<br />

march plants grow at an altitude from 1900-2400 m.<br />

More than 720 fungal species are known in the Caucasus Biosphere reserve.<br />

Algae, lichens and mosses still remain to be studied. Water-marshy and overmoist<br />

habitats of high mountains have been found to contain 48 species of moss,<br />

belonging to 15 families and 17 genera. The sphagnum family is the most<br />

representative (1 4 species).<br />

Among rare plants listed in the Red book of the USSR, 32 species grow in the<br />

reserve. Among woody plants and shrubs, these are: common yew, Kolkhid<br />

boxwood, hop hornbeam, bladder nut, and others; among grass plants these are:<br />

Caucasian deadly nightshade, gentian, harebell, and many Orchidaceae (pyramidal<br />

orchid, spurred coral root, and others).<br />

The territory of the reserve is located within the boundaries of two botanico-<br />

geographical provinces - North Caucasian and West-Caucasian, where 9<br />

geobotanical regions are identified. lntraregional differences of the plant cover are<br />

particularly distinct in the forest belt.<br />

Broad-leaved forests grow at an altitude up to 1300 m. Oaks occupy a small area<br />

(2%) predominantly around the periphery of the reserve. They are confined to<br />

southern slopes at an altitude up to 900 m. These forests consist mainly of 4<br />

species of oak: pedunculate, sessil, Iberian and Gartvis. They are mixed with<br />

hornbeam, Caucasian pear, oriental apple, wild myrobala, common and Norway<br />

maples, Caucasian common linden, common ash. The most widespread among<br />

shrubs are pontic azalea, hazel nut, briars, and common elder.<br />

Forests with a predominance of oriental beeches grow within 500-1500 m.<br />
