The features of succession dynamic of secondary forest after clear-cutting in Ufa plateau

The geobothanical survey of secondary forest communities which have been formed after clear-cutting of the forests of 4 associations: Equiseto-Piceetum (class Vaccinio-Piceetea ), Chrysosplenio-Piceetum, Brachypodio-Abietetum and Euonymo-Pinetum (class Querco-Fagetea ) in the Bashkir Cis-Urals have been carried out. During clear-cutting without severely damaging of the moss cover in the communities of grass green moss spruce-fir forests of association Equiseto-Piceetum the significant changes in the floristic composition were not observed. There is some decrease in coenotical positions of boreal species, while the meadow and ruderal species occur sporadically. During restorative succession the coenotical positions of dark coniferous species and birch have intensified and the alien species quickly fall out. Such course of succession in relation to alien species observed in the herb layer of communities formed on the site of cuttings dark coniferous-broadleaved nemoral forests of associations Chrysosplenio-Piceetum and Brachypodio-Abietetum. In the sites of skidding during stripped-coupe cutting in the grass pine-broadleaved forests of association Euonymo-Pinetum take place the strong breaking of the ground cover. At the first years of restorative succession the large number of ruderal species have invasion into these communities.
