Data of the vascular plant species composition in the ecotone “forest – forest edge – cutover” ten years after logging of a bilberry spruce stand in the north-taiga subzone of the Arkhangelsk Region are reported. Differences among zones of the ecotone complex regarding species percent covers and frequency of occurrence were revealed. Changes in the ground cover species abundance compared to earlier reforestation stages (2–5 years after logging) are discussed. Plant species were grouped according to their response to logging and subsequent tree layer restoration. The first group consists of typically forest-dwelling species whose phytosociological optimum corresponds to bilberry spruce forest conditions (Goodyera repens, Listera cordata, Vaccinium vitis-idaea, V. myrtillus, Hylocomium splendens). The second group includes the forest species that have demonstrated a negative response to logging and have been actively recovering their abundance since the time of tree layer formation in the cutover site (Carex globularis, Chamaepericlymenum suecicum, Equisetum sylvaticum, Gymnocarpium dryopteris, Luzula pilosa, Maianthemum bifolium, Melampyrum pratense, Oxalis acetosella, Pleurozium schreberi, Rubus arcticus, Trientalis europaea). The third group is made up of forest edge species (Empetrum nigrum and Orthilia secunda). The forth group comprised typically forest-dwelling apophytes, which responded positively to logging, but declined in abundance as the tree layer was forming (Avenella flexuosa, Chamaenerion angustifolium, Polytrichum commune). A separate group consists of the species whose response to logging and subsequent tree layer formation could not be detected by geobotanical, and has no statistic proof. It is shown that 10 years after logging, although the tree layer has formed, each zone of the ecotone complex has preserved their specific traits of the ground cover structure.
