Since these snails reproduce slowly and only exist in a few limited locations, they are very vulnerable to threats. Habitat destruction for agriculture and invasive species are noted as the biggest reason for population decline, though fires, collecting, drought, hurricanes, logging and human recreation are also to blame.
Achatinella apexfulva is a (probably) extinct species of colorful, tropical, arboreal pulmonate land snail in the family Achatinellidae, once present on Oahu, Hawaii. A. apexfulva is the type species of the genus Achatinella. The specific name, apexfulva, meaning "yellow-tipped", refers
In addition, invasive species such as Norway rats, Jackson's chameleons, and the highly predatory snail Euglandina rosea have been involved in the extinctions and declines of the native tree snails.

Achatinella livida is classified as critically imperiled as of 2014 with a wild population sie estimate of at least 76 individuals. [2] Similar to most Hawaiian tree snails, there are various threats to its survival, such as habitat loss and being endangered by Euglandina rosea and other predators. [6]
