What is the primary cause of decline for bandicoot populations reintroduced to the mainland?
Answer
Intense predation pressure from introduced foxes.
The text clearly identifies the overwhelming threat driving population declines when bandicoots attempt to persist or re-establish on the mainland, even in protected areas. Foxes are consistently named as the single most significant cause of decline, far outweighing other native predators like dingoes or owls. This intense predation pressure, combined with habitat loss from land clearing, has made recovery extremely difficult on the mainland unless complete predator exclusion is implemented, highlighting the severity of the impact introduced predators have on these small marsupials.
