The history of woody plant introduction is closely related to the development of sea transportation and the European colonization of the world from the beginning of the 16th to the 19th century. European colonial powers established botanical gardens and experimental centers in different parts of the world. During the past two centuries, a lot of species have either spontaneously or by cultivation spread over a considerable area of their introduced range. Since the 20th century, the course of introduction has shifted from agricultural crops and ornamental trees and shrubs to economically important tree species. Activities have been directed towards species whose potential is significant for the production of timber, i.e. roundwood. Apart from their economic importance, the majority of introduced woody species contribute to the preservation of biodiversity and improve the quality of life of the human population on Earth. Throughout the 19th and especially in the 20th century the large- scale establishment of plantations for the production of timber for mechanical and chemical wood processing has been one of the main reasons for the introduction of a large number of species, especially conifers оf Pinus, Picea, Pseudotsuga genera and the species of Populus and Salix genera. This paper deals with the attitude of the human population to the introduction, the effects of introduced plants on native habitats and its indirect influence on the progress of woody plant improvement.
