protected by Bulgan River Nature Reserve.
description: The Bulgan River
originates in the Mongol Altai high mountains, flows into Ulungur Lake of
China. Watercourse of Bulgan River divides into large and small streams,
and isolated water bodies. The river runs through semi-desert
area and it has a spectacular view with dense reeds, aspen,
bushes and meadows, because this is the largest part of Altai Mountains
foothill with high moisture level. There are numerous bays, such as Tsagaan
Ereg, Sanjiin Tohoi, Balar Tohoi and Elst Tohoi, with dense reeds and shrubs.
for birds: Bulgan
river basin is rich with sparrows and raptors and it is an important area for
waterbirds and shorebirds that stopover here during migration. Globally threatened
bird species Swan Goose (Anser cygnoides), Eastern Imperial Eagle (Aquila
heliaca) and Lesser Kestrel (Falco naumanni) occur,
exceeding 1% of their flyway populations.
flora and fauna: Asian
Beaver (Castor fiber) considered
in danger of extinction throughout Mongolia, is abundant in Bulgan river basin,
thus the reintroduction of Asian Beaver to the other rivers was carried out
from Bulgan river. Construction work of hydroelectric dam in the Chinese
section of Bulgan River, creating a barrier to migration of wildlife and causing
habitat fragmentation along the river.
