The success of assisted migration for conservation purposes has been variable. Bellis et al.  identified 56 successes and 33 failures among 107 translocations of insects undertaken explicitly for conservation purposes. They concluded that failure was most strongly associated with the low numbers of individuals being released. Another potential source of failure is local adaptation: there is good evidence that adaptive differences among potential source populations can be important. For example, the transplants of Chamaecrista fasciculata were more successful when sourced from the most poleward existing sites, while individuals from more equatorial habitats performed poorly even when artificially warmed .
