The current state of Taimyr reindeer (Taimyr-Evenk population) and the probable reasons for its reduction
Abstract The North Siberian plain is the main fawning ground and summer feeding of wild reindeer of the Taimyr tundra population. After an explosive increase in numbers in 2000, when the population increased to 1 million of individuals, there is a decrease in the deer number. According to aerial sur...

| Summary: | Abstract The North Siberian plain is the main fawning ground and summer feeding of wild reindeer of the Taimyr tundra population. After an explosive increase in numbers in 2000, when the population increased to 1 million of individuals, there is a decrease in the deer number. According to aerial surveys in 2017, it amounted to 404-442 thousand of individuals, in 2019, according to research staff members of the Taimyr Nature Reserves, it decreased to 250-280 thousand. Based on mathematical modeling and analysis of information obtained when marking 17 deer with collars with satellite transmitters, the paper considers version of the population response to environmental factors. Against the background of tundra “greening”, the growth of plant biomass, the length of deer stay in Taimyr did not increase, but, on the contrary, it decreased almost three times and averages 63 days in comparison with the 1960s. The questions solved in this paper consider the reasons why deer leave their former feeding grounds in the middle, or even at the beginning of August and if a significant reduction in the volume of deer hunting will lead to a completely opposite effect. |
