Abstract

The results of the study on naturalization of adventive plants in Magadan region are given. The list of adventive flora of the region consists of 292 species and includes 22 pseudoaboriginals. Ergasiophygophytes include 42% of ephemerophytes, 34% of colonophytes, 16% of epoecophytes and 8% of agriophytes. Xenophytes consist of 15% of ephemerophytes, 40% of colonophytes, 26% of epoecophytes and 19% of agriophytes. Unintentionally introduced species have greater potential to naturalization. Pseudoaboriginal xenophytes have greater part of epoecophytes than other xenophytes. Sixteen percent of adventive species spread to natural ecotopes.
