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). This fast-moving mollusk uses its elongated lips to track the slime trails of its prey, traveling two to three times faster than a typical snail’s pace.

Members of E. rosea followed trails for both species found inside and outside its native range equally well. 2004). Clearly public education about the French Polynesia’s precious natural fauna and the dangers posed to such fauna by carnivorous biological control agents could help to reduce the likelihood of Euglandina being purposefully translocated to new islands. [4], The rosy wolfsnail has been ineffective as a biological control, [4] and instead targets smaller native and introduced snails [6] and slugs. 1989, Cowie 1992, Hopper and Smith 1992, in Cowie and Cook 2001). 2007.
