How many individuals comprised the entire mainland population of the Eastern Barred Bandicoot by 1988?
Answer
150 individuals.
The decline of the Eastern Barred Bandicoot (*Perameles gunnii*) reached a critical threshold before major conservation efforts were fully effective. By the year 1988, the situation on the Australian mainland was catastrophic. At that time, the entire remaining wild population was counted as having plummeted to a mere 150 individuals. These survivors were clustered closely together in one small geographic area near Hamilton in Victoria. This extremely low number underscored the urgency that led to the species being declared Extinct in the Wild on the mainland in 2013, necessitating the comprehensive captive breeding and reintroduction programs.
