in response to the impact of dftd on tasmanian devil populations, 47 devils have been shipped to mainland australian wildlife parks to attempt to preserve the genetic diversity of the species. the largest of these efforts is the devil ark project in barrington tops, new south wales; an initiative of the australian reptile park. this project aims to create a set of one thousand genetically representative devils, and is now a major focus of the insurance policy. the tasman peninsula is being considered as a possible "clean area" with the single narrow access point controlled by physical barriers. the tasmanian department of primary industries and water is experimenting on culling infected animals with some signs of success.
