This original StudyForA sequence supports Cambridge IGCSE Environmental Management 0680 Topics 1–4 for exams in 2027, 2028 and 2029. Named local examples are chosen by the learner and centre; verify current conditions and local context with reliable sources. It is not a Cambridge paper, official grade or complete course.
Before you begin
- Use the 2027–2029 syllabus and check your exam year and centre's entry arrangements. Topics 1–4 are taught on this page; Topics 5–7 are still being built.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which is an off-site genetic-resource strategy?
What you will learn
- Compare in-situ and off-site conservation options and judge how each protects species, habitats and genetic resources.
- Use evidence from an unfamiliar case to compare options and justify a context-sensitive judgement.
Know the conservation strategies
Strategies include sustainable harvesting of wild plant and animal species; sustainable forestry; national parks and reserves; wildlife corridors; seed banks; zoos and captive breeding; and ecotourism.
The syllabus also includes international cooperation against animal trade, regulation of trade in vulnerable and endangered species, and classifying organisms by threat level as threatened, endangered and extinct. These categories describe status; do not infer a formal threshold unless one is supplied.
Compare habitat-based and off-site measures
Parks, reserves, sustainable harvesting, forestry and wildlife corridors can conserve organisms in their natural ecosystems. Corridors may connect separated habitat, while rules and sustainable use can reduce pressure on species.
Seed banks, zoos and captive breeding conserve material or populations away from the original habitat. They can support future recovery, but do not by themselves protect the ecosystem where a species lives.
Evaluate benefits, limits and combinations
Every strategy has limits: protected areas need resources and enforcement; corridors need suitable land and can also allow disease or invasive species to spread; seed banks need viable material and careful storage; captive programmes need expertise and suitable habitats for any release.
Ecotourism can fund conservation and local livelihoods but may disturb habitats. International cooperation is important where trade crosses borders, yet monitoring and compliance matter. A strong evaluation matches several strategies to a specific threat and checks outcomes over time.

Pause and explain
Why may conservation strategies be combined?
Worked example
An endangered forest animal is threatened by habitat fragmentation and illegal trade. Recommend two complementary conservation strategies and explain one limitation for each.
Show the worked solution
- A protected reserve or wildlife corridor can protect habitat or connect populations, but land, management and monitoring are needed.
- International cooperation and regulation of trade can reduce illegal sales, but enforcement and reliable monitoring across borders are required.
- Track habitat connectivity, population evidence and trade or enforcement records to judge whether the combined plan is working.
Answer A reserve or corridor addresses habitat fragmentation, while trade cooperation addresses illegal trade. Both require management and evidence; the strategies tackle different parts of the threat.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A reserve protects nesting habitat, but a threatened bird is also sold in an international trade. Suggest one habitat measure and one trade measure.
Give me a hint
Choose strategies that target each pressure rather than relying on one intervention.
Compare my reasoning
- A national park or reserve can protect nesting habitat if it is managed and enforced.
- International cooperation and regulation of trade in vulnerable or endangered species can address cross-border trade.
- Monitor habitat condition, population trends and trade compliance to evaluate results.
Use managed habitat protection and cross-border trade controls together. Their success depends on enforcement and evidence of ecological and trade outcomes.
Look for these in your work
- Habitat pressure addressed
- Trade pressure addressed
- Monitoring included
Compare a seed bank with captive breeding for conserving a species' genetic resources. Give one benefit and limitation of each.
Give me a hint
Consider what is stored or maintained, and whether the natural habitat is protected.
Compare my reasoning
- Seed banks can preserve plant genetic material for future use, but collected seeds need suitable storage and viability checks.
- Captive breeding can maintain an animal population and support recovery, but it requires suitable facilities, expertise and an appropriate habitat for any release.
- Neither approach alone protects all ecological relationships in the original ecosystem.
Seed banks preserve stored seeds; captive breeding maintains live animals and may support recovery. Both have technical limits and do not replace habitat conservation.
Look for these in your work
- Methods distinguished
- Benefit and limitation for both
- Habitat limitation recognized
A tourism operator proposes wildlife viewing in a protected forest. Explain how ecotourism could support conservation, one risk it could create and two indicators for review.
Give me a hint
Balance funding and livelihoods against disturbance and habitat pressure.
Compare my reasoning
- Tourism income can support conservation work and provide local livelihoods linked to habitat protection.
- Poorly managed visitor numbers, access routes or noise may disturb wildlife or damage habitat.
- Monitor visitor numbers and income alongside habitat condition, disturbance indicators or species observations over time.
Ecotourism can provide funds and livelihoods but can also disturb wildlife. Review both conservation outcomes and local benefits, then adjust visitor management if needed.
Look for these in your work
- Conservation benefit explained
- A realistic disturbance risk identified
- Environmental and social indicators included
Common mistakes
- Assuming a seed bank protects habitat directly
- Treating ecotourism as impact-free
- Using threatened, endangered and extinct as interchangeable terms
- Assuming a protected-area boundary ensures effective enforcement
What can you explain now?
Which strategy directly links separated habitat areas?
Compare with the explanation
Wildlife corridors
The correct answer is “Wildlife corridors”. The alternatives “Seed banks” and “CFC alternatives” do not match the syllabus concept. Compare in-situ and off-site conservation options and judge how each protects species, habitats and genetic resources.

If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
