  1. 7. Ecological Succession 7.2 Conservation of Habitats

  2. Starter • What is conservation? Come up with a definition.

  3. Starter • Conservation is the management of the Earth’s natural resources in such a way that maximum use of them can be made in the future.

  4. Learning Objectives • Describe what conservation is • Explain how managing succession can help to conserve habitats Success Criteria • You can state the reasons for conservation and give examples of managing succession leading to the conservation of habitats

  5. What is conservation? • Conservation involves humans intervening to maintain ecosystems and biodiversity • It can involve caring for existing resources or reclaiming those that have already been damaged by human activity

  6. Reasons for Conservation • In pairs (or alone, if you really want), come up with a list of reasons for conservation

  7. Reasons for Conservation • Ethical: respect for living things, other species should be allowed to coexist • Economic: living organisms have a huge gene pool and may have the capacity to make millions of substances • Cultural and Aesthetic: habitats enrich our lives and inspire writers, poets etc who entertain and fulfil us

  8. Conserving habitats by managing succession • Climax communities do not contain all the species that existed in earlier stages • Maintaining habitats at different stages of succession can keep these species present, by preventing change to the next stage

  9. UK example • Much of the higher ground in the UK is moorland, sheep are grazed and the heather often burned on this land • This prevents the climax community being reached as the young tree saplings are destroyed, stopping progression to deciduous woodland

  10. Task • Work through the Application and How Science Works questions on page 109-110 of the textbook

  11. Learning Objectives • Describe what conservation is • Explain how managing succession can help to conserve habitats Success Criteria • You can state the reasons for conservation and give examples of managing succession leading to the conservation of habitats
