Tajikistan’s territory is typically divided into
peculiar geobotanical regions.
Each region has its own diversity of species,
habitats, and distribution of plant communities according to vertical zonation. |

seravschanica, Rosa kokanica).
3. 2400-3500 m. Forb-grasses steppes
Festuca sulcata, Cousinia stephanophora and Cousinia fedtschenkoana in combination
with tall-herb and grass-rich tall herb savannoids (Prangos pabularia).
Within the mountain river valleys same birch (Betula turkestanica) and
poplar (Populus tadshicistanica) forests are widely spread
4. 3400-3800 m. Cryophytic meadows (Puccinellia
