February 2 - Winter route accounting

The winter route record of the number of mammals in Polistovsky Reserve was completed.

In January, state inspectors of the reserve together with the theriologist Andrey V. Sapogov, an experienced specialist of Central-Siberian biosphere reserve, conducted measures to determine the number of species of mammals and birds in the reserve by the method of winter route accounting.

Such events repeat every year in the guard and reserve zone of two districts: Bezhanitsky and Loknyansky in order to determine the density of population and the number of mammals of Polistovsky Reserve. This year, at the time of accounting, the weather was good, and practically nothing prevented to pass routes, some of which lies in the swampy terrain and mixed forests. The average length of the route is approximately 12 kilometers, and 2 operational groups pass them on snowmobiles.

The counting of the tracks was carried out in two stages: on the first day, inspectors of the reserve passed the whole route and wiped off old traces, because in time their number increases, but only fresh, night or morning ones are counted. On the second day the enumerators went strictly along the same route, marked in the notebook all the new tracks crossing the route, indicating the species and number of animals that left traces. During the events, it was revealed that in most cases, moose and wolf flocks were walking along the same swamps in the vast swamp areas of the reserve, foxes, hare and bobcat marks were also found. It was discovered the feeding place of the white partridge - a rare species of bird that disappeared in most areas of Pskov region.

The results of the passage of the accounting will be given to the science department of Polistovsky Reserve in the form of a scientific report prepared by Andrey V. Sapogov, in which the total number of animals in the given territory will be calculated. The most interesting are the relative numbers, it can be judged on whether more or less animals and birds became in the current year compared to last year.
