Sahyadri Tiger Reserve Reintroduction Program: UPSC Current Affairs Story Arc
ExamRobot — UPSC prep tools
ExploreFor years, the northernmost tip of the Western Ghats was a 'tiger-less' tiger reserve. Between November 2025 and February 2026, this changed as three tigresses were translocated to reclaim a 1,600 km ancient corridor.
Overview
The Sahyadri Tiger Reserve (STR) Reintroduction Program is a high-stakes ecological restoration project in Maharashtra. While STR was notified in 2010, its resident tiger population had dwindled to near-zero, making it a 'sink' habitat rather than a 'source.' To fix this, the Maharashtra Forest Department and the National Tiger Conservation Authority (NTCA) launched a phased plan to move tigers from high-density areas like Tadoba-Andhari (TATR) and Pench to STR. This arc tracks the successful translocation of the first tigress, Chanda, followed by two more to establish a breeding nucleus. It matters because it tests the feasibility of creating a self-sustaining population in the northern Western Ghats, a crucial biodiversity hotspot.

Genesis
Trigger
On September 13, 2025, the Maharashtra Forest Department and NTCA officially initiated the translocation project, choosing Tadoba-Andhari and Pench as the source populations.
Why Now
The decision followed years of 'empty forest syndrome' in STR despite its high-quality habitat. Increasing tiger-human conflict in the Vidarbha region (Tadoba/Pench) provided a surplus of tigers that could be used to repopulate under-occupied reserves like Sahyadri.
Historical Context
This follows the 'Sariska model' (2008) and 'Panna model' (2009), where tigers were reintroduced after local extinction. Historically, STR had tigers, but poaching and habitat fragmentation led to their disappearance.
Key Turning Points
- [2025-11-13] Release of the first tigress, Chanda
It moved the project from administrative planning to biological reality.
Before: STR was a 'paper' tiger reserve. After: It became an active reintroduction site.
- [2026-02-10] Release of the third tigress
Reached a critical mass for the founding population to potentially become self-sustaining.
Before: High risk of failure due to individual isolation. After: Increased probability of establishing a breeding nucleus.
Key Actors and Institutions
| Name | Role | Relevance |
|---|---|---|
| Chanda | The 'Pioneer' Tigress | The first individual translocated on November 13, 2025, whose successful adaptation serves as a litmus test for the entire program. |
| Maharashtra Forest Department | Executing Agency | Managed the logistics of capture, transport over hundreds of kilometers, and soft-release monitoring in Koyana and Chandoli. |
Key Institutions
- National Tiger Conservation Authority (NTCA)
- Maharashtra Forest Department
- Tadoba-Andhari Tiger Reserve (TATR)
- Pench Tiger Reserve
Key Concepts
Tiger Translocation
The active movement of tigers from 'source' populations (overcrowded) to 'sink' habitats (empty but suitable) to ensure genetic diversity and species expansion.
Current Fact: Initiated on September 13, 2025, using tigers from TATR and Pench.
Northernmost Tiger Habitat
The specific geographic limit in the Western Ghats where tiger ecology transitions; STR holds this title for the Western Ghats chain.
Current Fact: STR spans the Sahyadri Ranges across Satara, Sangli, Kolhapur, and Ratnagiri districts.
Sahyadri-Konkan Corridor
A critical wildlife strip connecting STR to southern reserves in Karnataka (like Kali/Dandeli), essential for long-term genetic health.
Current Fact: The 2026 release of the third tigress aims to utilize this corridor for natural dispersal.
What Happens Next
Current Status
As of February 10, 2026, the third tigress has been successfully released into STR, completing the initial phase of the reintroduction.
Likely Next
Expect the translocation of a male tiger to facilitate breeding, followed by intense radio-collaring and monitoring of the 'founding' individuals.
Wildcards
Potential conflict with local communities in the four districts (Satara, Sangli, Kolhapur, Ratnagiri) if tigers stray into human settlements or if the Sahyadri-Konkan corridor is blocked by new infrastructure.

Exam Intelligence
Previous Year Question Connections
- Is the National Tiger Conservation Authority (NTCA) a statutory body? — The STR program is mandated and approved by the NTCA, confirming its statutory oversight in reintroduction protocols.
- Arrange Tiger Reserves from North to South (Dudhwa, Panna, Pench, Indravati). — Students must now place STR as the northernmost reserve in the Western Ghats of Maharashtra, potentially appearing in similar map-based questions.
Prelims Angles
- The STR is composed of two primary protected areas: Koyana Wildlife Sanctuary and Chandoli National Park.
- STR is located in the Sahyadri Ranges and spans four specific districts: Satara, Sangli, Kolhapur, and Ratnagiri.
- Tigers were translocated from the Vidarbha landscape (TATR and Pench) to the Western Ghats landscape.
Mains Preparation
Sample Question: Explain the significance of the Sahyadri-Konkan wildlife corridor. How does the tiger reintroduction program in Sahyadri Tiger Reserve contribute to the broader goals of 'Project Tiger' 2.0?
Answer Structure: Intro: Define STR and its status as a northernmost habitat. Body: Discuss the 'Source-Sink' dynamics and the importance of TATR/Pench. Analyze the corridor connectivity for genetic flow. Critical Analysis: Mention challenges like habitat fragmentation and human-animal conflict. Way Forward: Community-led conservation and corridor protection.
Essay Topic: The Tiger as a Sentinel: Ecological Health and the Future of India’s Biodiversity Hotspots.
Textbook Connections
Environment, Shankar IAS Academy (10th ed), Chapter 15: Protected Area Network, p. 223
Explains that Western Ghats are locally called 'Sahyadri' in Maharashtra and highlights the high population pressure in this hotspot.
Gap: Textbooks focus on southern reserves (Mudumalai/Bandipur); the reintroduction in STR is a contemporary shift not yet detailed in static editions.
Geography of India, Majid Husain (9th ed), Chapter 2: Physiography, p. 58
Describes the Sahyadri as the watershed of peninsular India, where rivers like Krishna rise.
Gap: While it describes the physical geography, it doesn't link the hydrology of the Koyana/Chandoli dams to the specific requirements of a tiger habitat.
Quick Revision
- STR was notified in 2010 but remained largely empty of tigers until 2025.
- The reintroduction is a collaboration between Maharashtra Forest Dept and NTCA (a statutory body).
- Translocation started: September 13, 2025.
- First tigress name: Chanda (translocated Nov 13, 2025).
- Third tigress release date: February 10, 2026.
- STR components: Koyana Wildlife Sanctuary and Chandoli National Park.
- STR Districts: Satara, Sangli, Kolhapur, and Ratnagiri.
- Source Reserves: Tadoba-Andhari (TATR) and Pench Tiger Reserve.
Key Takeaway
The Sahyadri Tiger Reserve reintroduction marks a strategic shift from passive protection to active landscape-level restoration in the Western Ghats.
