Threats Captive breeding has so far failed to increase numbers of Gilbert’s Potoroo. Loss of Genetic Diversity – Because of the small population of Gilbert’s Potoroos remaining, the species are at risk of loss of genetic diversity and Gilbert's Potoroo is the world's rarest marsupial & is Critically Endangered with only ~100 animals known. Gilbert's potoroo is Australia's most endangered marsupial. This potoroo has a long, thin snout curving downward that it uses to smell its surroundings; this trait is common in all potoroo species. In efforts to protect the remaining population, three Gilbert's potoroos (one male and two females) were translocated to Bald Island in August 2005 where they are free from predation. The group also helps with raising funds for the research and captive-breeding programs for Gilbert's potoroo. From translocation of the potoroo, the species was found to survive on many different kinds of fungi, not limited to the species available in its habitat at Two People's Bay. There is only one ex­tant pop­u­la­tion of Gilbert's po­toroos. Gilbert had collected several animals at King George Sound in Australia, including this potoroo.

Since that time an additional four potoroos have been sent to establish a breeding colony. Gilbert’s Potoroo (Potorous gilbertii) – only 40 or so of these rabbit-sized marsupials live in south-west Western Australia, but the population seems stable. In efforts to protect the remaining population, three Gilbert's potoroos (one male and two females) were moved to Bald Island in August 2005, where they are free from predation. In 2001, an action group was formed called the Gilbert's Potoroo Action Group (GPAG). Since that time, an additional four potoroos have been sent to establish a breeding colony.
