Assam has added 403.62 square kilometres of land to its Protected Forest network — what Chief Minister Himanta Biswa Sarma described as the biggest single green addition anywhere in India — with a major share of the expansion focused on the Laokhowa-Burhachapori landscape, a sanctuary where rhinos vanished after a catastrophic poaching wave four decades ago and have only in the past two years begun returning on their own.
Background
Laokhowa Wildlife Sanctuary, in Nagaon district on the Brahmaputra's south bank, once held a rhino population that had grown past 70 animals by the early 1980s. That progress was wiped out almost overnight. During the Assam Agitation, the sustained political unrest that gripped the state through the early 1980s, organised poaching gangs exploited the breakdown in policing and administrative control to kill more than 40 rhinos in Laokhowa within a matter of weeks in 1983. The handful of survivors fled to safer protected areas, principally Kaziranga and Orang, and Laokhowa's rhino population was effectively wiped out — a species locally extinct in a sanctuary that had, just years earlier, been considered a conservation success story.
Recovery took decades. A 2016 attempt to reintroduce two rhinos — a female and her calf, translocated from Kaziranga — ended in failure when both animals died within months from natural causes. It was not until December 2023 that two rhinos entered the Laokhowa-Burhachapori landscape and, this time, survived and settled into the habitat under close forest department monitoring. By early 2025, five rhinos had migrated into the sanctuary naturally via connected corridors from neighbouring protected areas — the first sustained, self-directed rhino presence in the landscape in roughly four decades.
That fragile, still-unfolding recovery is the backdrop against which the state's latest protected-area expansion lands. Kaziranga National Park itself, the world's premier stronghold for the greater one-horned rhinoceros, faces a related and increasingly urgent problem: during the Brahmaputra's annual monsoon floods, roughly half of Kaziranga's animals move to natural highland refuges in the adjoining Karbi Anglong hills, while the rest cross National Highway 37, which cuts through the park, to reach higher ground. Those movement corridors — natural escape routes wildlife has used for generations — have become increasingly cramped by encroaching human habitation, hotels, tea estates and illegal construction, prompting Supreme Court-monitored restrictions and, more recently, an ambitious 34.5-km elevated wildlife corridor project along NH-715 designed to let animals pass safely beneath the highway. Expanding protected forest cover around Laokhowa-Burhachapori, connected to the broader Kaziranga landscape, is explicitly framed by state officials as part of the same underlying strategy — giving wildlife more secure ground to move into, rather than relying solely on increasingly constrained corridors around the core Kaziranga park.
This latest expansion also follows Kaziranga's own sixth boundary expansion, approved by the Assam Cabinet in June 2025, which added roughly 47,306 hectares to the core park while excluding ten villages specifically to reduce human-wildlife conflict. Read alongside that earlier expansion, the new Laokhowa-Burhachapori protected-area addition suggests a sustained, multi-year state strategy of enlarging protected habitat across the wider Kaziranga landscape rather than a single, isolated announcement — though the two expansions cover different, non-overlapping sanctuary areas within the same broader ecological region.
Key Details
- Assam has added 403.62 square kilometres to its Protected Forest network — described by Chief Minister Himanta Biswa Sarma as the largest such single addition anywhere in India.
- A major focus of the expansion is the Laokhowa-Burhachapori landscape, intended to strengthen ecological linkages around the wider Kaziranga region.
- The additional protected area is expected to give wildlife — including the one-horned rhinoceros, elephants, tigers and other species — greater space to move and thrive, particularly relevant given Kaziranga's own increasingly constrained flood-season movement corridors.
- The expansion follows a period of slow, fragile rhino recovery in Laokhowa-Burhachapori: a failed 2016 reintroduction, followed by a successful natural settlement beginning in December 2023, and five rhinos migrating in naturally by early 2025 — roughly 40 years after the sanctuary's rhino population was wiped out in the 1983 poaching crisis.
- The move adds to a series of recent Assam wildlife-governance actions, including reconstitution of the State Board for Wildlife and expansion of the Kaziranga Wildlife Rescue Centre's rehabilitation work.
- It follows Kaziranga National Park's own sixth boundary expansion, approved in June 2025, which added roughly 47,306 hectares to the core park while excluding ten villages to reduce conflict — a separate but related expansion within the same wider landscape.
- The expansion comes even as Assam's statewide forest cover has recently trended in the opposite direction: the India State of Forest Report 2023 recorded an 83.92 sq km decline in Assam's forest cover between 2021 and 2023, the state's third-largest such decline nationally, even as the density of remaining forest — measured as Very Dense Forest area — improved.

Local Impact
For the fragile, still-recovering rhino population in Laokhowa-Burhachapori, more protected land translates directly into more secure habitat and reduced edge-effect pressure from surrounding human activity — a critical factor given how narrowly the population avoided permanent local extinction and how recently its recovery has actually begun. Conservation biologists generally regard larger contiguous protected areas as more resilient to poaching pressure and more capable of supporting genetically viable, self-sustaining wildlife populations than smaller, fragmented reserves, making the scale of this expansion directly relevant to whether Laokhowa-Burhachapori's rhino recovery ultimately proves durable or remains as fragile as it has been for the past four decades.
The contrast with Kaziranga's own conservation trajectory illustrates what durable protection can look like when it is sustained over time. Kaziranga lost 27 rhinos a year to poaching as recently as 2013 and 2014, but through a conservation model combining 253 anti-poaching camps, drone surveillance, all-women "Van Durga" patrol units, and shoot-on-sight orders for armed poachers caught in the park, the state drove rhino poaching to zero across Assam in 2022 — a milestone not achieved in 45 years — and Kaziranga specifically recorded 730 consecutive poaching-free days as of the state's most recent count, with the park's rhino population now standing at an estimated 2,613 animals as of the 2022 census, more than two-thirds of the world's entire wild greater one-horned rhino population. That turnaround, achieved over roughly a decade of sustained investment and enforcement, is the model Laokhowa-Burhachapori's newly expanded protected status will need to replicate if its own still-tiny, five-rhino population is to grow into anything resembling Kaziranga's recovery story rather than repeating the collapse of 1983.
For communities living around the expanded protected area, the practical implications include tighter restrictions on land use, grazing, and resource extraction within the newly protected boundaries — changes that, in similar expansions elsewhere in Assam, have generated both support (from those who benefit from eco-tourism and conservation-linked livelihoods) and friction (from those whose existing land use is curtailed). How the state handles boundary demarcation, compensation, and community engagement around the new protected area will shape whether local sentiment toward the expansion remains positive or becomes a source of contention, a pattern seen with several of Assam's past protected-area boundary changes.
Kaziranga's own most recent expansion offers a template the state appears to be following: when the park's sixth boundary expansion was approved in June 2025, officials specifically excluded ten villages from the newly added area precisely to reduce the potential for human-wildlife conflict and displacement disputes, rather than incorporating those settlements wholesale into the protected boundary. Whether a similar approach — carving protected status around, rather than through, existing settlements — has been applied to the Laokhowa-Burhachapori expansion is likely to be one of the more closely watched details as the state publishes the formal boundary notification for the new protected area.
The broader statewide forest-cover picture also complicates a purely celebratory reading of the announcement. Assam's overall forest cover declined by nearly 84 square kilometres between the 2021 and 2023 assessment cycles of the India State of Forest Report — the third-steepest decline of any Indian state in that period, behind only Tripura and Telangana. That means the current 403.62 sq km protected-area addition, while a genuine and substantial gain in formally protected status, does not by itself reverse the state's broader net forest-cover trend; protected-area designation restricts future land-use change within the new boundary but does not automatically restore forest that has already been lost elsewhere in the state to agriculture, settlement, or infrastructure expansion. Conservation researchers would likely note that the improvement in Very Dense Forest area recorded in the same period suggests at least some of Assam's remaining forest is maturing and thickening even as its total extent contracts — a genuinely mixed underlying trend that this latest protected-area expansion sits within, rather than fully reverses.
For Kaziranga specifically, a strengthened and expanded Laokhowa-Burhachapori landscape offers a partial answer to the park's chronic flood-season corridor problem — giving animals displaced or dispersing from Kaziranga during monsoon floods additional secure habitat within reach, rather than funnelling all displaced wildlife through the same increasingly encroached corridors toward Karbi Anglong. This does not resolve the encroachment pressure on Kaziranga's existing highland corridors, but it does create an additional option within the broader landscape.
What Happens Next
Forest department officials are expected to move toward formal demarcation, boundary notification, and on-ground protection staffing for the newly added protected area, a process that in past Assam expansions has taken time to translate from a Cabinet-level or ministerial announcement into fully enforced, patrolled boundaries. Given Laokhowa's specific history — its 1983 population collapse occurred precisely because a period of administrative and security breakdown created an opening for organised poaching — sustained, adequately resourced anti-poaching enforcement in the newly expanded zone will likely be viewed by conservationists as the real test of whether the expansion delivers lasting protection rather than a paper boundary increase.
The five rhinos currently present in Laokhowa-Burhachapori, along with any further natural migrants following the same corridors, will continue to be monitored closely by forest staff, with their survival and, ideally, successful breeding within the landscape serving as the clearest practical indicator of whether the expanded protected area is functioning as intended. Wildlife researchers and conservation groups, including organisations that have previously supported reintroduction efforts in the landscape, are likely to watch this population closely as a bellwether for the broader expansion's success.
Given how heavily Kaziranga's own turnaround relied on sustained, well-resourced enforcement infrastructure — the 253 anti-poaching camps and dedicated patrol units built up over roughly a decade — the practical test for Laokhowa-Burhachapori's expanded protected area will be whether comparable enforcement capacity is extended into the newly added zone in the near term, or whether staffing and patrol resources lag behind the boundary expansion on paper. Conservation organisations that track Assam's rhino population, including groups involved in the earlier reintroduction attempts, are likely to press the state forest department for a public timeline on staffing, camp construction, and patrol deployment specific to the new protected area, rather than treating the boundary announcement itself as the completed conservation action.
Separately, work on the 34.5-km elevated wildlife corridor along NH-715 through Kaziranga is expected to continue in parallel, and conservationists are likely to assess the Laokhowa-Burhachapori expansion and the elevated corridor project together, as complementary pieces of the same broader strategy to preserve wildlife movement across the wider Kaziranga landscape rather than as unrelated, standalone initiatives.
The state's own wildlife governance structure will also play a role in how the expansion is implemented going forward. The recently reconstituted State Board for Wildlife, chaired by Chief Minister Sarma and including representatives from conservation organisations such as Aaranyak, WWF-India and the Wildlife Trust of India alongside MLAs, is the body expected to oversee policy decisions affecting how the newly protected Laokhowa-Burhachapori zone is managed, including any future decisions on further reintroduction efforts, corridor connectivity projects, or adjustments to the protected boundary as on-ground conditions become clearer.
Frequently Asked Questions
How much protected forest land did Assam add?
Assam added 403.62 square kilometres to its Protected Forest network, which Chief Minister Himanta Biswa Sarma described as the largest single such addition anywhere in India.
Where is most of the new protected area located?
A major focus of the expansion is the Laokhowa-Burhachapori landscape in Nagaon district, intended to strengthen ecological connectivity around the wider Kaziranga region.
What happened to Laokhowa's rhino population in the 1980s?
During the political unrest of the Assam Agitation, organised poachers killed more than 40 rhinos in Laokhowa within a few weeks in 1983, wiping out the sanctuary's rhino population, which had numbered over 70 animals just years before.
Have rhinos returned to Laokhowa-Burhachapori?
Yes. After a failed 2016 reintroduction attempt, two rhinos entered and successfully settled in the sanctuary starting in December 2023, and five rhinos were present via natural migration by early 2025 — the first sustained rhino presence in roughly four decades.
How does this expansion relate to Kaziranga National Park?
Kaziranga's wildlife, particularly during monsoon floods, depends on movement corridors toward highland refuge areas that have become increasingly constrained by encroachment. The Laokhowa-Burhachapori expansion is framed as strengthening ecological linkages within the wider Kaziranga landscape, giving wildlife additional secure habitat.
What other species benefit from the expansion?
Officials cited the one-horned rhinoceros, elephants, tigers, and several other species as expected beneficiaries of the additional protected habitat.
What is the Kaziranga elevated wildlife corridor?
It is a separate, roughly 34.5-km elevated stretch planned along National Highway 715 through Kaziranga, designed to allow wildlife to pass safely beneath the highway rather than crossing at grade level during their seasonal flood-driven migrations.
What risks does the expanded protected area face?
Given Laokhowa's history of catastrophic poaching during a period of administrative breakdown in 1983, sustained anti-poaching enforcement and on-ground protection staffing in the newly expanded zone will be critical to ensuring the expansion delivers durable protection.
