Why in news
Conservationists are highlighting the ecological impact of relocating Tasmanian devils to Maria Island, which led to the disappearance of a 3,000-pair little penguin colony.
Background
In 2012, 28 Tasmanian devils were relocated to Maria Island as an 'insurance population' to protect against facial tumour disease. The population grew to 90, resulting in the loss of a 3,000-pair little penguin colony.
Facts for Prelims

For Mains
Q. Discuss the ecological risks and ethical dilemmas associated with 'insurance populations' and the translocation of endangered species in biodiversity hotspots.
Dimensions to cover in your answer
- Ecological imbalance: Unintended predation on native species due to lack of natural predators in relocated habitats
- Conservation trade-offs: Balancing the survival of a single endangered species against the integrity of local biodiversity
Keywords: insurance population · translocation · biodiversity conservation · ecological impact · species protection
