Abstract
The introduction of rare and disappearing species in Siberia was analyzed. The relations between the category of the threatened state of a species and the ecological, geographical and historical determination of its being rare were revealed in addition to the success of the introduction. The significance of the problem of genetic preservation was shown from the veiwpoint of population genetics. Plant introduction methods were determined on the basis of historical and anthropogenic causes of the species being rare. A map of introduction successes and the codes of the introducent and reintroducent was developed.
