Coote & Loeve (2003) concluded that E. rosea was extinct in the wild on Huahine, strongly suggesting that the successful re-introduction of partulids into the wild on Huahine might be possible.Conservation actions in the wild may be limited to identifying and protecting populations of partulid snails that offer some possibility of persistence in the presence of Euglandina (Ó Foighil 2009). Campbell, B.G. Most governments and other authorities appear to be aware of the potential threat posed to native fauna by E. rosea, however, under pressure to do something about A. fulica, they may misguidedly consider the introduction of E. rosea (and other species such as the flatworm Platydemus manokwari).
