| Summary: | T HE necessity for dividing the tundra area into subzones had been recog- nized in the nineteenth century, and during that century and at the beginning of the twentieth it was frequently mentioned by Baer, Ruprecht, Schrenk, Tanfiliev, and Pohle. Trautfetter (1851) showed on the map of European Russia a “tundra region ” and subdivided it into two districts: that of “alpine willow”, which approximately corresponds to the present “arctic tundra ” subzone, and that of “dwarf birch”, which approximately corresponds to the present “typical (or moss and lichen) tundra ” and “dwarf shrub tundra ” subzones (see Phytogeographical Map of the U.S.S.R., Scale 1: 4,000,000, Acad. of Science of the USSR Press, Leningrad, 1956). It was not until 1916 that Gorodkov in his classic “An attempt to divide the west Siberian lowland into phytogeographical districts ” (Gorodkov 1916) provided the first division of the large northern area between the Urals and the Yenisey River into well-defined phytogeographical districts. Among them he recognized and described the “arctic tundra ” subzone, which there includes the northern parts of the Yamal and Gydan peninsulas and borders in the south on the “typical tundra ” subzone. The term “arctic tundra subzone” was applied to the northernmost floristic subzones in the USSR also by Berg (1930), but he did not show their boundaries on account of lack of data. In the early 1930’s many workers tackled the problem (Andreev 1932 |
