PRESERVATION OF THE BIRD SPECIES
Measures to minimize the impact on the bird fauna are aimed at the two most vulnerable species: the mandarin duck and the oriental white stork.
The habitat of the mandarin duck happened to be directly into the flood zone in the area of the reservoir of the Nizhne-Bureyskaya HPP in the Amur Region.
The key habitats and natural nesting of this species were threatened with extinction. To conserve the population of the mandarin duck, about 100 artificial nest boxes have been built above the level of the reservoir design marks, mainly on tributaries.
According to the monitoring results, it was established that the nest boxes began to be populated with mandarin ducks before the reservoir was filled, which confirmed the efficiency of this measure and determined the necessity to install additional artificial nest boxes. In 2016, installation of additional artificial nest boxes and the monitoring of the effectiveness of this solution was continued in order to maintain the Mandarin population in the process of a water body creation.
The south of the Amur Region is the nesting place for most of the world population of the oriental white stork. The distribution of the population of this species is in the downstream of the Nizhne-Bureyskaya HPP. In order to minimize the possible negative impact on the population of the oriental white stork, the artificial nest supports were installed with the support from UNDP Project. The nests can hold up the weight of the stork. In 2017, it is planned to install artificial nest supports for the oriental white storks in the Muravievsky Nature Reserve, as the Amur regional public environmental organization “AmurSoES” and the regional “Directorate for the Protection and Exploitation of Wildlife and Specially Protected Natural Territories” filed a request to the energy sector.
Moreover, according to the information of the Amur regional public ecological organization “AmurSoES”, in 2016, there were about 100 inhabited nests of oriental white storks in the southern regions of the Amur Region, and more than 40% of them were located on the supports of overhead transmission lines.
The PJSC Yakutskenergo (subsidiary of RAO ES of the East) equips the high-voltage power transmission lines passing through a specially protected natural territory in Ust-Maysky ulus in Yakutia with special bird protection devices. 24 species of birds are protected there.
Also, PJSC Yakutskenergo provides isolation of the power transmission lines with a special cable SIP in the territory of the Natural Park “Living Diamonds of Yakutia”, where the high-voltage transmission line 6-10 kW passes through. In addition, the company equips transformer substations on transmission lines with fences and covers to prevent animals from entering into the substation and into the mechanisms of the substation.
