Geobotanical division into districts (regionalization) of the Bolshezemelskaya tundra and surrounding areas

I. A. Lavrinenko



Actuality of large-scale geobotanical division into districts due to the need to optimize environmental management, conservation of the resource potential and protection of tundra ecosystems. Geobotanical division into districts scheme of the Bolshezemelskaya tundra and surrounding areas (ridge Pai-Khoi, Pechora River valley) have been prepared using thematic maps, remote sensing data, numerous publications and results of own work. The territory was divided into 65 geobotanical districts which have been described by the dominant types of vegetation, landscape, soil and geomorphological features.

In previous work (Geobotanical division into districts ..., 1989), three large geobotanical districts covering Bolshezemelskaya and Malozemelskaya tundra, has been proposed. We performed a comparative analysis of the vegetation cover structure using maps that showed significant differences between vegetation of the Malozemelskaya and Bolshezemelskaya parts of these districts. So, we have identified for the Bolshezemelskaya tundra independent geobotanical districts – Bolshezemelskyi primorskyi, West Bolshezemelskyi and PechoraHarayahskyi. Valley of the Pechora River in its lower reaches is different from the surrounding areas Bolshezemelskaya and Malozemelskaya tundra dominated by subarctic floodplain plant communities, so we offered to independent Nizhnepechorskyi geobotanical districts.

Key words: geobotanical zonation, geobotanical district, geobotanical region, prevailing types of vegetation, Bolshezemelskaya tundra
