- In recent years some authors have reported the occurrence of Mahonia aquifolium in Polish forests and started to focus on this species as a potential plant invader in our native plant communities. The authors of this paper have found 5 sites with hybrid Mahonia aquifolium × M. repens. Based on these results we regard successful ornitochory of this species as quite common. It proves a major role of ornitochory in fleshy-fruited plants dispersal strategy. The aim of this paper is to focus on major ways of dispersal of such kind of plants. We took into account its abundance in forests as an alien species dispersed by fruit-eating birds. In 1995 we found the first site with a few seedlings of Mahonia in the surroundings of Trzebinia. In years 2007-2009 this area was very carefully explored and there were total three more localities with Mahonia found. Another two records were found accidentally. Generally there were five localities recorded. Usually seedlings were located under canopy of trees. Usually they grew under other fleshy-fruited plant species (i.e. Sorbus aucuparia, Rosa sp., Cotoneaster sp., Malus sp., Ribes nigrum). The birddispersed seeds originated from parent plants cultivated in gardens. In one case the nearest possible parent plant was situated about 1000 meters from its hypothetic ornitochorous offspring. In other cases distances were shorter. The shrubs reproduced only vegetatively. Very weak flowering and fruiting (or their complete absence) may be caused by unfavorable environmental conditions (i.e. growing in shade). Although we did not record any signs of expansion of the species into our native plant communities, in unfavorable conditions of the surveyed locations we have recorded very strong vegetative growth and increase in the cluster size in the occupied area.
