A4.2.5—Evidence for biodiversity crisis Topic Practice
Students practise evaluating real-world evidence for biodiversity loss by comparing metrics like Simpson’s reciprocal index across habitat types and data sources.
How this is tested
- interpret changes in species richness or evenness between disturbed and undisturbed habitats using survey data
- compare reliability of citizen science versus peer-reviewed studies when assessing population declines in IPBES
