In-situ Conservation of Biodiversity
In-situ conservation is the protection of species, genetic diversity and ecosystems in their natural habitats through protected areas and community-linked conservation practices.
In one line: In-situ means in the site where the species naturally lives.
Concept Practice Coming SoonUnderstand it
- In-situ conservation allows species to continue living and evolving in their natural ecological setting.
- It protects not only individual organisms but also food webs, breeding sites, gene flow and species interactions.
- Important examples include national parks, wildlife sanctuaries, biosphere reserves, biodiversity hotspots and sacred groves.
- Hotspots are regions with high endemism and serious threat, so they receive conservation priority.
- Sacred groves are community-protected forest patches where traditional protection helps preserve native species.
- Exam questions often require students to explain why in-situ conservation is preferred when whole habitats and ecological processes must be protected.
Example
Rule to remember
Conservation rule: protect species in their natural habitat when the goal is to preserve ecosystems, interactions, natural selection and genetic exchange.
See it worked out
Follow the example line by line, then use the same method on new questions.
Worked example
If a question asks why a biosphere reserve is an in-situ method, write that it conserves organisms within a large natural area while allowing protection of habitats, species interactions and genetic diversity.
Method you can reuse
- 1Start with the definition using the phrase natural habitat.
- 2Name two or three protected-area examples.
- 3Explain what is conserved: species, genes, habitats and interactions.
- 4For hotspots, add high endemism and high threat.
- 5For sacred groves, mention community protection.
Visual tip
A map-style or network diagram may show protected areas connected with surrounding habitats. Labels should include national park, wildlife sanctuary, biosphere reserve, hotspot, sacred grove and natural habitat.

Common wrong answer
Calling botanical gardens or seed banks in-situ methods.
Why it loses marks: They preserve organisms or germplasm outside the natural habitat.

Exam tip
Write it in the exam
Each point is worth about one mark. Write point 1 for a 1-mark question and keep adding points as the marks go up.
How CBSE asks it
Answer plan
- 1
Enough for 1 mark
In-situ conservation is the protection of species, genetic diversity and ecosystems in their natural habitats through protected areas and community-linked conservation practices.
- 2
Add for 2 marks
Example: A national park protects wild animals along with their habitat and ecological interactions. Sacred groves in parts of India preserve patches of native vegetation because local communities protect them culturally.
- 3
Add for 3 marks
In-situ conservation allows species to continue living and evolving in their natural ecological setting.
