Study Notes
Managing the conservation of biodiversity involves strategies like species protection, habitat management, and international cooperation to maintain healthy ecosystems and support human wellbeing. Biodiversity — the variety of life on Earth across genetic, species, and ecosystem levels.
Example: Genetic diversity within species helps adaptation.
Native Species — species that occur naturally in a habitat, adapted to local conditions.
Example: Kangaroos in Australia.
Invasive Species — non-native organisms that spread rapidly in new environments.
Example: Zebra mussels in North American lakes.
Ecosystem Services — benefits provided by ecosystems like pollination and water purification.
Example: Bees pollinating crops.
IUCN Red List — a comprehensive inventory of the conservation status of species.
Example: Classifies species from Least Concern to Extinct.
EDGE Programme — prioritises species that are evolutionarily distinct and endangered.
Example: Pangolins are EDGE species.
Captive Breeding — maintaining species in controlled environments for later release.
Example: Breeding pandas in zoos.
Protected Areas — designated regions for conservation, like national parks.
Example: Yellowstone National Park.

Typical Exam Questions
- What is biodiversity? Biodiversity is the variety of life on Earth across genetic, species, and ecosystem levels.
- How do invasive species impact biodiversity? Invasive species can outcompete native species, alter habitats, and introduce diseases.
- What is the purpose of the IUCN Red List? It classifies species based on their extinction risk to guide conservation efforts.
What Examiners Usually Test
- Understanding of biodiversity and its importance
- Differences between native and invasive species
- Knowledge of conservation strategies and their effectiveness
