ANNOTATION:

In 2014-2017 with the use of remote and ground-based research, the analysis of different-scale, different-time and multidirectional changes in the biota and ecosystems of the Russian Arctic in the conditions of synergy of the changing climate and expanding economic activity was carried out. The results of the first stage of the research were published earlier. It is revealed that in total territories with the destabilized mode of development make more than 10% of the area of azrf. The reasons for the destabilization of ecosystems — “greening” of the tundra-are mainly due to an increase in productivity due to the growth of the projective cover of grassy and shrub vegetation. It is the driver of many modern processes of dynamics of Arctic biota (composition, distribution and changes in the number of birds and mammals) and the causation chain affects the traditional economy of the indigenous peoples of the North and regional features of the industrial development of the Russian Arctic. The article presents data on changes in population dynamics, distribution and migration of some representatives of the Arctic biota — lemming, wild reindeer, wolverines, sea and water birds. The greening of the Arctic is making major adjustments to the strategy for the conservation of the biota and ecosystems of the Russian Arctic, related to the implementation of obligations under a number of international agreements, primarily the Convention on climate change and the Convention on biological diversity.
