Abstract:
The present paper focuses on the complex analysis of 3 plant
communities within the EPILOBION ANGUSTIFOLII (Rübel 1933) Soó 1933
(SYN. CARICI PILULIFERAE-EPILOBION ANGUSTIFOLII TX. 1950)
alliance: 1. Senecioni sylvatici-Chamaenerietum angustifolii (Tx. 1937), Soó
1961 (Syn. Epilobietum angustifolii Rübel 1933, Senecioni sylvaticiEpilobietum angustifolii Tx. 1937; Senecioni-Epilobietum angustifolii (Hueck
1931) Tx. 1950), 2. Calamagrostio arundinaceae-Digitalietum grandiflorae
(Silling. 1933) Oberd. 1957 (Syn. Calamagrostietum arundinaceae Puscaru
et al 1959; Digitali ambigue-Calamagrostietum arundinaceae Sillinger
1933) şi 3. Deschampsietum flexuosae Issler 1942 emend. Borza 1946. The
phytocoenoses of the first two plant communities takes place in the
interpenetration of the beech, fir tree and of spruce, usually springing up on
slightly or heavily slanted lands, rarely on the flat one in the mountainous
region. These plant communities are widespread in the investigated territory,
because of the massive woodcutting that took place in the past few years. The
phytocoenoses represented by Deschampsia flexuosa covers limited areas in
the the researched territory, usually growing at the edge of forest paths, on
stubbed fields, at the edge of the forests, on eroded slopes. The three
associations have a particular significance, being pioneer associations in
afforestation playing an important antierosive role.
