With the support of Rosneft, a scientific expedition to study wild reindeer in Western Taimyr, which was conducted as part of the corporate environmental program "Tamura", has been completed. Scientists from the Siberian Federal University (SFU) traveled about 2.5 thousand km by boat along the Pyasina River, just over 1.5 thousand km as part of a radial route along the Dudypta, Tareya and Pura rivers, and over 700 km along the Khatanga and Kheta rivers.
The main goal of this year's wild reindeer research is to count the numbers and assess the distribution of animals in Western Taimyr using instrumental and ground-based observation methods. Annual monitoring of bioindicator animals allows us to obtain a comprehensive picture of the impact of climate change on the state of Arctic ecosystems.
During boat and stationary observations, photo and video recordings of deer were made. The data obtained will be processed at the stage of office work using special computer programs. To determine migration routes, specialists installed GPS transmitters on several deer. Also, following the expedition, scientists noted the appearance of large, predominantly male herds on the right bank of the Pyasina.
Rosneft has been studying wild reindeer since 2014. During this time, large-scale ground and aerial surveys of animals have been conducted in Evenkia and Taimyr. Using satellite tags installed on the reindeer, scientists have tracked the entire annual cycle of their migration and identified seasonal behavior patterns.
Rosneft pays special attention to environmental issues and biodiversity conservation and is implementing the largest comprehensive Arctic region study program since Soviet times. As part of the Tamura program, which began in 2024, scientists plan to update information on the state of key animal species in the northern region.
"Tamura" involves studying the Kara subpopulation of polar bears, wild reindeer populations in western Taimyr, and valuable bird and fish species in the Yenisei estuary. The data obtained will allow scientists to draw conclusions about the state of ecosystems and develop measures to preserve the region's biodiversity. The program will last until 2027. In 2025, scientists have already conducted three expeditions to study the Kara subpopulation of polar bears, and ten expeditions will be conducted in just four years.
