In Yamal, the populations of peregrine falcons, red-breasted geese, arctic foxes, and lemmings were counted, and the movement of forest fauna into the tundra was noted: ravens, foxes, and water voles. The 26th field season has concluded at the "Erkuta" research station, located in the Erkuta River basin, 225 km along the Obskaya-Bovanenkovo railway. Scientists have completed all the tasks set for the summer field season at the "Erkuta" research station. It is located in the southwest of the Yamal Peninsula, in the subzone of shrub tundra. Fieldwork there usually focuses on ecology, biology, geography, and geology. GoArctic supports scientific research in the Arctic and frequently writes about ecology, including that the population of gyrfalcons, listed in the Red Book, has increased to 32 individuals in the Yamalo-Nenets Autonomous Okrug (YNAO). These birds nest on bridge supports and lay their eggs directly in the snow to fulfill their "built-in reproduction program" in time. Scientists feared that industrialization would interfere with this program, but the birds have adapted to the new reality. The population of other Red Book bird species, such as peregrine falcons and red-breasted geese, also increased by several dozen individuals, according to the results of the 26th field season at the "Erkuta" station. Additionally, the successful reproduction of waders and ptarmigans was tracked, reports the press service of the YNAO government. Scientists counted not only birds: this year, a high number of collared lemmings was recorded; 20 arctic fox dens were found, and the number of pups in litters was counted; biomass calculations of plants in special enclosures were conducted—an experiment that began back in 2014. Over the summer, several thousand specimens of insects from various families, genera, and species were collected in special traps. The conclusion drawn was that, despite the prolonged spring, most tundra inhabitants successfully reproduced. A notable feature of this season was the advancement of forest species into the tundra: seven raven nests were discovered; for the first time since 2014, a fox den was found, and the water vole became a species regularly captured in rodent traps.
