On giving the status «complex reserve» to the State natural zoological reserve Iyusskiy (the Republic of Khakassia)

State natural reserves are territories (water areas) that are of particular importance for preservation or restoration of natural complexes or their components and for maintenance of the ecological balance. State natural zoological reserve «Iyusskiy» was founded in 1980. It is located on the east slope of Kuznetskiy Alatau mountain ridge in the middle course of the river White Iyus in the western part of Shira area of the Republic of Khakassia on the area of 30 000 hectares. The reserve «Ijusskiy» performs the functions of maintenance of integrity of natural communities, preservation, reproduction and recruitment of wild animals that are valuable in the economic, scientific and cultural sense and are rare and disappearing. It is a place of winter concentration of hoofed mammals. In the state natural zoological reserve «Iyusskiy», realisation of activities on recruitment of animals listed in the Red book of the Republic of Khakassia, such as the argali, the Siberian ibex,209the musk deer, the marmot, is also possible. On the territory of the state natural zoological reserve Iyusskiy», a set of measures of different character is stipulated: restrictive; nature protective; reproducing; biotechnical. The territory of the reserve is between two large mining objects - Kommunarovskiy and Balahchinskiy gold ore areas. Kommunarovskiy ore unit is of high ecological danger, for it has an operating mine and a concentrator, which annually make about 300 thousand tons of waste. Two tailing pits are used to recycle it; they are separated from the valley of the river Bolshaya sobaka by fill dams, which require constant maintenance service and technological control. In case of their failure the polluted waters of the rivers Big Syia and White Iyus will flow to the central and northern parts of the reserve. Besides the territory of the reserve covers a significant part of Yefremkinsky karstic site, which has 34 large and small caves that are objects of active cave tourism. Annually thousands of tourists visit these places, which leaves a negative impact on the environment. Taking into account the above-stated, we consider it expediently to prove at the republican level the necessity of giving to the territory of the state natural zoological reserve «Iyusskiy» the status «complex reserve» with protection of the entire natural complex, including the underground and surface waters, and the sites of nature
