Biology Year 11 - Module 4 - Lesson 18
Conservation — Strategies, Ethics and Australian Case Studies
1. Key Ideas
In 1989, the eastern barred bandicoot was declared Extinct in the Wild in Victoria. Foxes had killed the last wild individuals. But a small captive population survived. Through three decades of captive breeding, predator-proof fencing, and careful reintroduction, the bandicoot clawed back. In 2021, its status was upgraded to Endangered — the first Australian mammal to recover from Extinct in the Wild. Conservation is not nostalgia. It is applied ecology, hard choices, and the refusal to accept that what is lost must stay lost.

5. Short Answer Questions
1. Q1. A small marsupial is down to 20 individuals in the wild. Should conservation funds be spent on captive breeding or on protecting its remaining habitat? Predict which strategy would be more effective and explain the trade-offs.
2. Q2. The Australian government must choose between creating one large national park or ten small reserves of equal total area. Predict which would protect more species in the long term, and justify your answer using concepts from Lessons 15–17.
