Diana Vyrostkova, a researcher at the Commander Islands National Park, has returned from a scientific mission on the uninhabited Medny Island in the Commander Archipelago. Five other scientists remain on the island to continue their fieldwork.
The expedition began in mid-May. Over two and a half months, the fieldwork included population counts at the South-East marine mammal rookery, a site where hundreds of Steller sea lions and tens of thousands of northern fur seals gather annually to reproduce.
The research also focused on the unique population of the Mednovsky Arctic fox subspecies. This involved conducting route surveys, inspecting known burrows, searching for new habitats, trapping the animals, and collecting samples to assess the overall health of the population.
Extensive data was collected on rare and vulnerable species inhabiting Medny Island, such as the Commander rock ptarmigan, sea otters, and Commander wrens. The majority of these animals are officially protected and listed in the Red Data Book of Russia.
Operating on an isolated island requires significant physical exertion – the challenging environment yields continuous data that is critical for the study and long-term conservation of the local ecosystem.
Scientific operations on Medny Island are ongoing, with the five remaining national park staff members executing a comprehensive research program. Initial plans scheduled the remaining researchers to conclude their studies and return from the field in mid-August.
