Definition

Animals which have been translocated by human agency into lands or waters where they have not lived previously, at least during historic times. Such translocation of species always involves an element of risk if not of serious danger. Newly arrived species, depending on their interspecific relationships and characteristics, may act as or carry parasites or diseases, prey upon native organisms, display toxic reactions, or be highly competitive with or otherwise adversely affect native species and communities.
