Pressure/threats to key biodiversity
On the western border are cattle tracks leading to alpine pastures. On the northern border there are often cases of illegal intrusions by shepherds with livestock and poachers. In 1995 by the decision of the Tashkent region’s mayor, 115 hectares (the right bank of the Shavazihurdsay river) was removed from the territory. This has had a negative effect on the fauna.
Conservation responses/actions for key biodiversity
Specialists from the Chatkal Reserve have been monitoring the condition of the ornithological fauna for many years. Between 2001 and 2003, a wide variety of zoological researches were carried out as part of the West Tian-Shan project.
