Phytosociological studies carried out in the forests of Silesian Upland and Głubczyce Plateau during the years 1994-2000 showed a widespread distribution of Impatiens parv!flora. It ranges from coniferous and mixed forests to alder carrs, riverside carrs, oak-hornbeam phytocoenoses, and beechwood associations. The optimal conditions for Impatiens parviflora are those found in Ti/io-Carpinetum typicum. Nevertheless, the highest percentage cover of that species occurred in heavily degenerated communities which were the result of clear-felling and tree planting.
