Over 2,500 trees found girdled inside Chhattisgarh’s Udanti-Sitanadi Tiger Reserve Forest officials have detected extensive girdling of Sal, Bija and Tendu trees, with satellite imagery indicating major habitat degradation linked to alleged encroachment. Environment · 3 Oct 2026 · GS: GS2, GS3, Essay · Exam yield: High WHY THIS MATTERS The Karka episode shows that tiger conservation can fail when ecological protection is separated from land rights, compensation and local participation. It also demonstrates how satellite imagery, field sampling and drone mapping can reveal forest loss that ordinary inspection may miss. (indianexpress.com) IN PLAIN WORDS Udanti-Sitanadi Tiger Reserve is a large protected forest landscape in Chhattisgarh, spread across Gariaband and Dhamtari districts. In its Karka area, officials found more than 2,500 mature Sal, Bija and Tendu trees with their bark cut in rings. This is called girdling: removing the bark interrupts the movement of water and nutrients, so the tree gradually dies even though it may remain standing for some time. (indianexpress.com) The Karka settlement had been relocated in the 1980s after construction of the Sondhur Dam. Forest officials say some residents later returned, cleared forest for cultivation and used girdling to kill trees without immediately cutting them. Their investigation alleges that more than 30 hectares had been encroached by 2026, compared with 22 hectares in 2016. Sample plots reportedly showed over 1,500 trees per hectare in nearby forest but only 50–100 in the affected area. Satellite images showed dense forest in 2016 and sharply reduced cover in 2017. (indianexpress.com) The dispute is not only about illegal forest use. Officials say 55 people received compensation, while around 32 families claim they never received promised relief and therefore never moved. A fresh Preliminary Offence Report has been registered against two villagers, while drone mapping and further verification are underway. The larger lesson is that conservation becomes durable only when habitat protection, legally valid relocation, livelihood security and accountable enforcement move together. (indianexpress.com) KEY FACTS • More than 2,500 trees in the Karka area of Udanti-Sitanadi Tiger Reserve were reportedly girdled, a process that cuts the bark and gradually kills trees. • Forest officials observed a sharp reduction in tree density compared with adjacent forest areas, supported by satellite-image comparisons. • The affected species include Sal, Bija and Tendu, which are important components of central Indian forest ecosystems. • The forest department alleges that relocated villagers returned and encroached on the area; around 32 families dispute the claim and say they did not receive promised compensation. • A fresh preliminary offence report has been registered against two villagers, highlighting tensions between wildlife protection, relocation and livelihood rights. HOW WE GOT HERE Karka was historically a forest village in the Sondhur Dam catchment, within the erstwhile Sitanadi Sanctuary. After the dam was built, residents were relocated during the 1980s. The present dispute arises because official records and community testimony differ on whether compensation was fully paid and whether relocation was complete. The Forest Department says 55 people received compensation from the Water Resources Department; affected families contest this and say around 32 families remained or returned because relief was not received. (indianexpress.com) Udanti-Sitanadi was notified as a tiger reserve in 2009. It has 851.09 square kilometres of core area and 991.45 square kilometres of buffer area, with ecological links towards Odisha and the Indravati landscape. The Wildlife (Protection) Act, 1972 requires recognition of rights, informed consent, livelihood arrangements and Gram Sabha involvement before compulsory resettlement for creating inviolate tiger habitats. The Forest Rights Act, 2006 separately recognises community forest resource rights, including protection, regeneration and management. Thus, enforcement against encroachment must be combined with verification of rights and procedural fairness. (ntca.gov.in) THE BIGGER PICTURE Environmental — Habitat degradation beyond tree counting Girdling kills standing trees and can rapidly convert a dense forest into a fragmented and less functional habitat. The affected species—Sal, Bija and Tendu—are components of central Indian dry deciduous forests and support food chains, shade, soil protection and local livelihoods. Karka also lies in a wider wildlife movement landscape, including an elephant corridor. Loss of tree cover can reduce shelter and food availability, disturb animal movement and increase human-wildlife conflict. The reported fall from over 1,500 trees per hectare nearby to 50–100 trees per hectare in the affected area indicates severe local degradation, though final estimates require systematic verification. (indianexpress.com) → Forest degradation is a landscape problem: losing trees can disrupt wildlife movement, water security and ecological resilience. Social — Relocation, compensation and trust deficit The central social issue is the gap between formal relocation and lived rehabilitation. Officials rely on records showing compensation to 55 people, while around 32 families say they were excluded or never accepted relocation terms. If families lack land, housing, livelihood access or secure documentation at the new site, they may return to the original habitat. This creates a cycle: unresolved displacement produces reoccupation, reoccupation is treated as encroachment, and coercive action further reduces trust. The case therefore illustrates why rehabilitation must be independently verified at household level rather than inferred from departmental records alone. (indianexpress.com) → A relocation order is not the same as successful rehabilitation; consent, compensation and livelihood restoration determine legitimacy. Constitutional — Balancing conservation with forest rights The Wildlife (Protection) Act, 1972 enables protected-area governance, but Section 38V safeguards require rights recognition and informed consent before resettlement for inviolate tiger habitats. The Forest Rights Act, 2006 recognises community forest resource rights and the role of the Gram Sabha. These laws need harmonised implementation: community rights do not authorise fresh forest clearing, but conservation status cannot erase previously recognised rights. In Karka, the reported 2020 recognition of community forest resource rights over 2,208 hectares makes transparent boundary, title and management verification essential before eviction or prosecution. (indianexpress.com) → Conservation enforcement must be lawful, evidence-based and consistent with recognised forest rights and Gram Sabha safeguards. Science & Tech — Combining field evidence with remote sensing The episode shows the value and limits of technology. Satellite imagery reportedly identified crop fields in 2006, 22 hectares of encroachment by 2016 and more than 30 hectares by 2026; comparison of 2016 and 2017 images also indicated abrupt canopy loss. Field sample plots supplied tree-density estimates, while GPS-based mapping and DGPS-enabled drones are being used for finer boundaries. Remote sensing can establish change over time, but it cannot alone determine ownership, causation or the identity of offenders. Ground verification, chain-of-custody procedures and community participation are therefore necessary. (indianexpress.com) → Technology can detect and measure forest loss, but legal conclusions require corroborated ground evidence and due process. THE BIG DEBATE Should the State prioritise immediate eviction and prosecution in Karka, or first resolve compensation and forest-rights claims? For: • Protected-area integrity is being damaged; delayed action may encourage further clearing and weaken deterrence. • Girdling and cultivation inside a tiger reserve threaten habitat, wildlife corridors and future human-wildlife conflict management. • A fresh offence report and precise drone mapping can target responsibility rather than penalise an entire community. Against: • Disputed compensation and incomplete relocation can make return a consequence of administrative failure, not simple criminality. • Recognised community forest resource rights and Gram Sabha safeguards require verification before eviction or coercive action. • Large-scale enforcement without livelihood alternatives may deepen conflict and push communities into greater dependence on forests. The balanced take: The State must stop ongoing damage immediately, but enforcement should be individualised and evidence-based. Eviction or prosecution cannot substitute for a rights audit, compensation verification and lawful rehabilitation. The sound approach is a parallel track: protect the habitat now, while an independent process settles claims, restores livelihoods and establishes community-backed conservation responsibilities. ANSWER IT IN MAINS Encroachment in protected areas is often a governance failure as much as an environmental offence. Discuss with reference to Udanti-Sitanadi Tiger Reserve. (GS3) How to attack it: Begin with Karka’s tree-girdling evidence; analyse habitat loss, relocation failures, compensation disputes, rights recognition and enforcement capacity; conclude with technology-enabled, community-backed landscape governance. Quote this: National Tiger Conservation Authority profile: Udanti-Sitanadi has 1,842.54 square kilometres and forms part of a wider connected forest landscape. (ntca.gov.in) How should India balance wildlife conservation with the rights and livelihoods of forest-dwelling communities? (GS2) How to attack it: Use the Wildlife (Protection) Act and Forest Rights Act as the legal frame; compare conservation imperatives with consent, rehabilitation and Gram Sabha safeguards; recommend rights-compliant protection rather than conservation by displacement. Quote this: Section 38V of the Wildlife (Protection) Act, 1972 and Ministry relocation guidelines requiring rights recognition, consent and livelihood arrangements. (moef.gov.in) Explain how geospatial technology can improve environmental governance while recognising its limitations. (GS3) How to attack it: Introduce satellite change detection; discuss field plots, GPS, DGPS drones and evidence verification; assess privacy, attribution and institutional capacity; conclude that technology should support, not replace, due process and local participation. Quote this: Karka’s reported sequence of satellite assessment, field sampling and DGPS drone mapping. (indianexpress.com) Protected-area management must move from fortress conservation to participatory conservation. Examine. (Essay) How to attack it: Use Karka as the hook; contrast exclusionary protection with rights-based stewardship; connect habitat restoration, community forest resource rights, trust and enforcement; conclude with shared responsibility and measurable ecological outcomes. Quote this: Forest Rights Act, 2006 provisions on community forest resource rights, alongside the National Tiger Conservation Authority’s landscape approach. (indianexpress.com) PRELIMS QUICK-FIRE • [Geography] Udanti-Sitanadi Tiger Reserve was notified in 2009 and has 851.09 square kilometres of core area. (ntca.gov.in) — Do not confuse the core area with the total reserve area of 1,842.54 square kilometres. • [Data] The reserve covers 1,842.54 square kilometres: 851.09 core and 991.45 buffer, according to National Tiger Conservation Authority data. (ntca.gov.in) — Core and buffer figures are not interchangeable. • [Term] Girdling means removing bark around a tree, interrupting nutrient movement and gradually causing death. (indianexpress.com) — It is not the same as immediate felling or uprooting. • [Geography] Karka lies in the Sondhur Dam catchment and was relocated during the 1980s after dam construction. (indianexpress.com) — The relocation link explains the present compensation and return dispute. • [Data] Forest officials reported over 2,500 girdled trees and tree density of 50–100 per hectare in the affected area. (indianexpress.com) — The tree count is described as ocular and requires further verification. • [Constitution] The Wildlife (Protection) Act, 1972 requires rights recognition and informed consent for specified tiger-habitat resettlement. (indiacode.nic.in) — Tiger-reserve status does not automatically extinguish forest rights. • [Scheme] The Forest Rights Act, 2006 recognises community forest resource rights to protect, regenerate, conserve or manage forests. (indianexpress.com) — Community rights are not a blanket permission for fresh clearing. • [Data] Satellite imagery showed 22 hectares of encroachment by 2016 and more than 30 hectares by 2026, according to the report. (indianexpress.com) — These are departmental findings reported in the news, not a final judicial determination. WHAT SHOULD HAPPEN 1. Conduct an independent household-level audit of compensation, land titles, relocation promises and current community forest resource claims. A verified social baseline can distinguish deliberate encroachment from unresolved displacement and prevent collective punishment. (Wildlife (Protection) Act, 1972; Forest Rights Act, 2006; Ministry of Environment, Forest and Climate Change relocation guidelines.) 2. Complete GPS and DGPS drone mapping, ground-truth satellite findings and publish a transparent habitat-loss map with a clear chain of evidence. Accurate spatial evidence is needed to identify the affected plots, quantify tree mortality and assign responsibility fairly. (National Tiger Conservation Authority monitoring framework and the ongoing mapping process reported for Karka. (indianexpress.com)) 3. Adopt consent-based rehabilitation with land, housing, public services and livelihood support before any final displacement action. Relocation becomes durable only when families receive secure alternatives and can verify that promised benefits have actually reached them. (Section 38V of the Wildlife (Protection) Act, 1972 and the Ministry’s Critical Wildlife Habitat relocation guidelines. (moef.gov.in)) 4. Create a community forest-protection compact with Gram Sabhas, fire and anti-felling patrols, restoration of native species and benefit-sharing. Local residents are more likely to protect habitat when their legal role, duties, incentives and grievance channels are clearly defined.

(ntca.gov.in)) JARGON, DEMYSTIFIED • Girdling — Removing bark in a ring around a tree, cutting the pathways that carry water and nutrients and eventually killing the tree. (Often used to kill trees while avoiding immediate visible felling.) • Tiger Reserve — A protected landscape notified for tiger conservation, generally divided into a core area and a buffer area. (Udanti-Sitanadi was notified in 2009.) • Core area — The more strictly protected part of a tiger reserve intended to provide secure habitat with minimal disturbance. (It is different from the buffer area.) • Buffer area — The surrounding part of a tiger reserve where conservation is combined with regulated human use and livelihood concerns. (Buffer does not mean unprotected.) • Community Forest Resource Rights (CFRR) — Rights recognised for a community to protect, regenerate, conserve or manage traditionally used community forest resources. (Recognised under the Forest Rights Act, 2006.) • Gram Sabha — The village assembly of adult residents that exercises specified local decision-making and consultation functions. (Its role is significant in forest-rights recognition and relocation safeguards.) • Preliminary Offence Report (POR) — A forest-department record initiating action when a suspected offence under forest or wildlife law is detected. (It is not equivalent to a final conviction.) REVISE IN 30 SECONDS • Karka was relocated after Sondhur Dam construction in the 1980s; present claims concern compensation and return. • Officials reported over 2,500 girdled trees and more than 30 hectares of encroachment by 2026. (indianexpress.com) • Girdling removes bark and gradually kills trees by disrupting nutrient and water transport. • Udanti-Sitanadi Tiger Reserve was notified in 2009 and totals 1,842.54 square kilometres. (ntca.gov.in) • Conservation action must combine habitat protection with rights verification, consent and livelihood rehabilitation. • Satellite images, field plots and DGPS drone mapping together improve evidence quality but do not replace due process.
