oday in Lithuania alien woody plants belonging to more than 3000 taxa are cultivated. They were introduced into Lithuania during the period of a few centuries. Most foreign plans have arrived into Lithuania through Western Europe, thus the regularities of the introduction of alien plants into Lithuania in the 14th–20th centuries are similar to the process of introduction in Western Europe. However, the time of introduction of certain plants, their quantity and the course of some periods are slightly different. Alien woody plants were introduced into Lithuania later than in Western Europe. In the 20th century the introduction of woody plants into Lithuania has been influenced by Russia, but recently the process becomes similar to the introduction in Western Europe again.
