Abstract

The most invasive tree and shrub species in Polish forests
More than 200 woody plant species of alien origin can be found in Polish forests. A considerable part of them was introduced into the forest environment purposefully, whereas a relatively small group of taxa has found its way there as a result of spontaneous migrations from cultivations situated outside forests. The majority of the alien trees and shrubs is rarely found, has not settled permanently and does not pose a significant threat to forest biological diversity. Approximately 10% of the above mentioned number of species can be treated as invasive plants. They include, among others: Acer negundo, Amelanchier lamarckii, A. spicata, Aronia ×prunifolia, Celttis occidentalis, Clematis vitalba, Cornus sericea, Cotoneaster lucidus, Fraxinus pennsylvanica, Prunus serotina, Quercus cerris, Quercus Rubra, Robinia pseudoacacia and Spiraea tomentosa. On the basis of the field observations, the authors characterised dynamic trends of the species and indicated factors that contribute to their spread in forest areas in Poland.
