Individual cases show that assisted migration can be successful. Anich and Ward  extended the geographic breeding range of a rare bird, Kirtland's warbler, Setophaga kirtlandii, by 225 km by using song playbacks to attract migrating individuals. Wadgymar  successfully transplanted an annual legume, Chamaecrista fasciculata, to sites beyond its current poleward range limit, while Liu  found that all but one of 20 orchid species survived when transplanted to higher elevations than their current range limits. After introducing two British butterfly species to sites ~65 and ~35 km beyond their poleward range margins, Willis  observed that both of these populations grew, expanded their ranges and survived for at least the 8 year span of the study.
