The method of study of bean goose Anser fabalis breeding area optimum in Nenets Autonomous Area using GIS-analysis is tested. For this purpose all of the data on routes counting by the author in the nestling and precocial period of the bird’s life of this species in Bolshezemel’skaya tundra in 2007-2013 were processed. All of the data of routes counting were referred to concrete plots, which were calibrated in the WGS 84 coordinate system. GPS-coordinates of the plots with high exponents of the abundance of nesting birds (not less than 10,3 birds per 1 km2) were loaded in the map of the vegetation of the Nenets Autonomous Area in GIS OziExplorer. The distribution of the plots with high exponents of the number of nesting birds were analysed according to the vegetation types. It was stated that plots with high exponents of the the number of nesting Anser fabalis are situated in the areas with 3-types of vegetation: coastal (seaside), polygonal and bumpy-plain mires. The model of the optimum of breeding areas of been goose were elaborated for all of the territory of Nenets Autonomous Area using the method of extrapolation of vegetation types correlated with high index of the birds (Anserfabalis) breeding. The analysis of spatial distribution of the plots with high index of breeding of been goose shows that the plots are situated mainly in the central part of the Nenets Autonomous Area: in the north-west part of Malozemel’skaya tundra and on the whole of the territory of Bolshezemel’skaya tundra. This conclusions are reflected in the results of other researches, who stated the fact, that the percent of breeding been goose (as compared with the whole population of this species) in the eastern parts of Nenets Autonomous Area is noticeably lower than in the western and central parts of it.
