The snail extinction prevention program (SEPP) or Hawai’i snail extinction program, is a partnership between US Fish and Wildlife Service, the Hawaii Department of Land and Natural Resources-Division of Forestry and Wildlife and the University of Hawaii founded in 2012 and currently directed by David R. Sischo that is trying to prevent the extinction of Hawaii’s many rare snails such as "Achatinella" and snails of the family Amastridae.
Actions taken.
Snail enclosures.
One of the ways the SEPP tries to save those rare snails is by keeping them in an fenced and constantly monitored enclosure in the Hawaiian forest that keeps them away from invasive snails, such as the Rosy Wolfsnail and other introduced predators, such as the Jackson's chameleon, the land flatworm "Platydemus manokwari", and black rats.
Enclosure walls.
The walls of the SEPP snail enclosures includes a smooth lined wall to prevent chameleons, a steel fence, protected with a rim to ensure wolfsnails do not climb over the fence. Behind the steel fence, there are electric wires to prevent any wolfsnails that do get in from swallowing the native snails whole.
Lab snails.
The SEPP also keeps snails in a laboratory in, Kawainui Marsh, Oahu, Hawaii.
Evacuation.
In 2018 Hurricane Lane approached the lab and the snails that lived in the lab had to be evacuated. There are ongoing concerns about future evacuation problems since as of 2022 there are over five thousand snails living in the lab, while there were fewer snails living in the lab in 2018. 
"Achatinella pupukanioe".
In 2015, the SEPP team found a tree full of "Achatinella pupukanioe", a species thought to be extinct since the 1980s. The SEPP decided to leave them alone, but later when they went to collect the snails for the lab they were gone, possibly swallowed whole by rosy wolfsnails.
