In-Situ Conservation: Meaning, Types, Examples & UPSC Notes

Study Notes · Environment & Ecology · GS III

In-situ conservation protects species in their natural habitat through national parks, sanctuaries, biosphere reserves, and sacred groves. Full UPSC notes.

In-situ conservation is the protection of plant and animal species in their natural habitat, allowing ecosystems and evolutionary processes to function intact, in contrast to ex-situ conservation which preserves organisms outside their natural setting in zoos, botanical gardens, and gene banks. Under the Convention on Biological Diversity (CBD), 1992, in-situ conservation is treated as the primary strategy for conserving biological diversity. In India, it is operationalised through national parks, wildlife sanctuaries, biosphere reserves, tiger and elephant reserves, conservation and community reserves, and sacred groves, under the Wildlife (Protection) Act, 1972, Biological Diversity Act, 2002, and Environment Protection Act, 1986. For UPSC, in-situ conservation is foundational to GS-III biodiversity questions.

What Is In-Situ Conservation

In-situ means "on site". The approach ensures that:

CBD Article 8 obliges signatories to create protected area systems, regulate biological resources outside protected areas, promote ecosystem-based management, rehabilitate degraded ecosystems, and control alien invasive species.

In-Situ vs Ex-Situ Conservation

FeatureIn-SituEx-Situ
LocationNatural habitatArtificial/controlled environment

ScaleEcosystem-levelSpecies or gene-level

EvolutionContinues naturallyLimited; risk of domestication
ReintroductionNot needed for core rangeNeeded to restore wild populations
ThreatsHabitat loss, invasivesDisease outbreaks, genetic drift

Most countries use a complementary strategy: in-situ as the backbone, with ex-situ as backup for critically endangered species.

In-Situ Conservation Methods in India

India protects nearly 5.32% of its geographical area under a layered network of protected areas.

1. National Parks (Section 35, Wildlife Protection Act, 1972)

2. Wildlife Sanctuaries (Section 26A, Wildlife Protection Act, 1972)

3. Biosphere Reserves (MAB Programme of UNESCO)

4. Tiger Reserves (Project Tiger, 1973; NTCA under WPA amendment 2006)

5. Elephant Reserves (Project Elephant, 1992)

6. Conservation and Community Reserves (2003 amendment to WPA)

7. Sacred Groves

8. Ramsar Sites (Wetlands)

9. Marine Protected Areas

Challenges

UPSC Relevance

Prelims focus:

Mains GS-III angle:

Sample PYQ angle: "How does biodiversity vary in India? How is the Biological Diversity Act, 2002 helpful in conservation?" and "Discuss the key strategies adopted by India for in-situ conservation of biodiversity." — build your answer around the layered protected area network, flagship species programmes, legal framework, and international commitments, and conclude with gaps that must be addressed to meet the 30 by 30 target.
