Scheme for crocodile sanctuaries
Scheme for Crocodile Sanctuaries — UPSC Study Note
1. At a Glance
- India is home to all three species of crocodilians found on the subcontinent: Gharial (Gavialis gangeticus), Mugger/Marsh Crocodile (Crocodylus palustris), and Estuarine/Saltwater Crocodile (Crocodylus porosus). [S1]
- All three faced near-extinction by the early 1970s due to indiscriminate hunting for meat, egg collection, and habitat loss, prompting India to launch one of the world's largest captive-breeding and sanctuary programmes. [S2]
- The scheme is directly linked to India's wildlife conservation architecture under the Wildlife (Protection) Act, 1972 and was a landmark example of international technical cooperation (FAO/UNDP + Government of India). [S1][S2]
- Relevant for Prelims (species, sanctuaries, Acts) and Mains GS-III (conservation, biodiversity, human-wildlife conflict). [S2]
2. Why in the News
- June 2026 — The Hindu republished an archival article (from its historical print editions) describing how Dr. H.R. Bustard, FAO (UNDP) expert deputed to the Andhra Pradesh Government, surveyed the Coringa mangrove forest (Kakinada Forest Division) and the Godavari river (Devipatnam to Peramtapalli, including the Papi Hills stretch) for crocodile habitat suitability, and prepared draft sanctuary schemes for both areas. [S3]
- This archival feature highlights the origins of India's crocodile sanctuary framework, in the broader context of the 50th anniversary of the Crocodile Conservation Project (1975–2025). [S2]
3. Background & Evolution
| Year | Milestone |
|---|---|
| 1972 | Wildlife (Protection) Act enacted — provided legal basis for sanctuaries and species protection. |
| 1974–75 | Dr. H.R. Bustard (FAO/UNDP expert) surveys habitats in Andhra Pradesh, Odisha, UP, Bihar; recommends conservation-cum-farming sanctuaries. [S3] |
| 1975 | Crocodile Conservation Project (CCP) launched with UNDP assistance in 34 locations across West Bengal, MP, UP, Bihar, and Nepal. [S2] |
| 1975 | Gharial Research & Conservation Centre established at Tikarpara (Satkosia Gorge Sanctuary, Odisha). [S2] |
| 1975 | Saltwater Crocodile Research & Conservation Centre established at Dangamala, Bhitarkanika Wildlife Sanctuary, Odisha. [S2] |
| 1979 | Mugger Crocodile Research & Conservation Centre set up at Ramatirtha, Simlipal Sanctuary, Odisha. [S2] |
| 1975–1982 | 16 crocodile rehabilitation centres and 5 crocodile sanctuaries established across India. [S2] |
| 1982 | Wild release tally: 879 gharials, 493 muggers, 190 estuarine crocodiles reintroduced. [S2] |
| 2023 | Census counts 1,793 estuarine crocodiles (including 20 whitish individuals) in Bhitarkanika alone. [S4] |
- Predecessor context: Pre-1972 there was no statutory framework; crocodile skins were commercially traded; FAO under UNDP flagged India's crocodilian crisis in early 1970s. [S1][S3]
4. Core Static Facts
Three Species of Indian Crocodilians:
| Species | Common Name | Primary Habitat | IUCN Status |
|---|---|---|---|
| Gavialis gangeticus | Gharial | Ganga, Brahmaputra, Mahanadi river systems | Critically Endangered |
| Crocodylus palustris | Mugger/Marsh Crocodile | Rivers, reservoirs (freshwater) | Vulnerable |
| Crocodylus porosus | Estuarine/Saltwater Crocodile | Estuaries of major rivers, mangroves | Least Concern (globally) |
[S1][S3]
Key Sanctuaries/Centres: - Bhitarkanika (Odisha) — primary estuarine crocodile sanctuary [S2][S4] - Satkosia Gorge (Odisha) — gharial sanctuary [S2] - Simlipal (Odisha) — mugger sanctuary [S2] - Coringa Mangroves (Kakinada, Andhra Pradesh) — identified for estuarine crocodile farming [S3] - Papi Hills–Peramtapalli, Godavari (Andhra Pradesh) — identified as excellent freshwater crocodile habitat [S3]
Implementing Framework: - Nodal Ministry: Ministry of Environment, Forests & Climate Change (MoEFCC) - International Partner: FAO/UNDP (technical and financial assistance, 1975 onwards) - Enabling Law: Wildlife (Protection) Act, 1972 (Schedules I and II for crocodilians) - Programme: Crocodile Conservation Project (CCP), 1975
Programme Scale: - Launched in 34 locations across multiple states [S2] - 16 rehabilitation centres + 5 sanctuaries established by 1982 [S2] - Total wild releases by 1982: 1,562 individuals (879 gharials + 493 muggers + 190 estuarine) [S2]
5. Multi-Dimensional Analysis
Environmental
- All three species were facing extinction by the early 1970s due to hunting (meat, skin), egg collection, and riverine habitat degradation. [S3]
- Crocodilians are apex predators and keystone species in riverine and estuarine ecosystems; their decline signals broader ecosystem collapse.
- Coringa mangroves (Kakinada) and Sundarbans represent critical mangrove-estuarine habitats for saltwater crocodiles; Sundarbans population estimated at ~100 individuals. [S1]
- Gharial, now Critically Endangered, has experienced a dramatic range contraction to a few river stretches in UP and MP despite captive breeding. Low genetic diversity in managed populations is a documented threat. [S5]
Legal / Constitutional
- Wildlife (Protection) Act, 1972 — Schedule I (gharial, estuarine crocodile) provides the highest protection; trade, hunting, possession prohibited.
- Mugger is in Schedule II of WPA 1972 (as of foundational listing).
- CITES listings apply: Gharial in Appendix I; Mugger and Estuarine Crocodile in Appendix I/II depending on population/country. [S1]
Administrative
- The 1975 programme was state-implemented with central and UNDP funding — classic concurrent-list challenge of coordination across Odisha, UP, Bihar, MP, West Bengal, Andhra Pradesh. [S2]
- Bhitarkanika's faulty conservation policy was flagged as early as the 1990s — overcrowding of estuarine crocodiles, inadequate buffer zones, human-wildlife conflict. [S6]
- Dr. H.R. Bustard's role as FAO/UNDP expert advising state governments (AP, Odisha) illustrates the technical-assistance model of conservation governance. [S3]
Scientific / Technological
- Captive breeding and rearing (egg collection, incubation, hatchling rearing, juvenile release) was the core methodology — adapted from IUCN Crocodile Specialist Group best practices. [S1][S2]
- Microsatellite genetic analysis (2021 studies) reveals low genetic diversity in captive-bred gharial populations — a warning against relying solely on captive breeding for long-term viability. [S5]
- Estuarine crocodile census methodology in Bhitarkanika uses spotlight counts along creek transects — now standardised across India.
Historical
- India's CCP (1975) was one of the earliest state-sponsored captive breeding + wild release programmes in Asia, predating many analogous global efforts.
- The initiative draws philosophical lineage from Project Tiger (1973) — both were UNDP-assisted, species-specific, and sanctuary-centred. [S2]
6. Recent Developments (last 12–18 months)
- 2024 (World Crocodile Day) — Down to Earth reported on the 50th anniversary of India's crocodile conservation project (1975–2025); one of its original architects expressed concern about the future of Bhitarkanika amid policy drift. [S2]
- 2023 — Bhitarkanika annual census recorded 1,793 estuarine crocodiles, including 20 whitish (leucistic) individuals — a record count underscoring programme success. [S4]
- June 2026 — The Hindu republished the original 1970s archival news about Dr. Bustard's surveys in Andhra Pradesh (Coringa, Papi Hills), drawing public attention to the genesis of the sanctuary scheme. [S3]

9. Related Topics to Study Next
| Topic | Connection |
|---|---|
| Project Tiger (1973) | Launched just before CCP; same UNDP-assisted, sanctuary-centred model — often compared in questions on India's conservation history. |
| Wildlife (Protection) Act, 1972 | Statutory backbone of both crocodile sanctuaries and all scheduled species protection. |
| CITES (Convention on International Trade in Endangered Species) | All three Indian crocodilian species are CITES-listed; India is a signatory — Prelims-tested repeatedly. |
| Mangrove Ecosystems (Coringa, Sundarbans, Bhitarkanika) | Estuarine crocodile habitat; also linked to coastal regulation, CRZ, climate vulnerability. |
| Critically Endangered Species of India | Gharial sits alongside Great Indian Bustard, Gangetic Dolphin — common Prelims cluster. |
| IUCN Red List Categories | Understanding Critically Endangered vs Vulnerable vs Endangered — tested in species-identification MCQs. |
| Ramsar Wetlands of India | Several crocodile habitats (Bhitarkanika, Chilika) are Ramsar sites — convergence point in exam questions. |
| Gangetic River Ecosystem Conservation | Gharial recovery is directly tied to National Mission for Clean Ganga and river flow restoration. |
10. Common Errors / Trap Areas
- Mugger vs Gharial habitat confusion — Gharial is a river specialist (fast-flowing, sandy-banked perennial rivers); Mugger is adaptable to reservoirs and slower water; Estuarine is coastal/mangrove. Do not conflate.
- Wrong sanctuary–species pairing — Bhitarkanika = estuarine; Satkosia = gharial; Simlipal = mugger. Exam options deliberately swap these.
- CCP launch year: 1975, not 1972 — 1972 is the Wildlife (Protection) Act year; the Project started in 1975 with UNDP funding. Aspirants often merge these two dates.
- Dr. Bustard's role — He was an FAO (UNDP) expert advising the state government (Andhra Pradesh), not a central government appointee. Questions may test the federal dimension.
- Gharial IUCN status — It is Critically Endangered, not merely Endangered. This distinction matters when questions ask to identify India's "most threatened" crocodilian.
