Wildlife & Protected Areas of Assam: National Parks, Sanctuaries, Tiger Reserves & Ramsar Sites
Wildlife and protected areas of Assam represent one of the most remarkable conservation networks in India. Tropical forests, Brahmaputra floodplain grasslands, Himalayan foothills, wetlands, river islands, swamp forests and hill ecosystems support the greater one-horned rhinoceros, Bengal tiger, Asian elephant, wild water buffalo, pygmy hog, golden langur, hoolock gibbon, swamp deer, Gangetic river dolphin and hundreds of bird species.
The extraordinary wildlife diversity of Assam is closely connected with the state's physiography. The Brahmaputra floodplain supports extensive grasslands and wetlands, the Himalayan foothills support dense forests and wildlife corridors, Upper Assam contains important evergreen rainforest, while Karbi Anglong, Dima Hasao and western Assam provide extensive hill-forest habitats.
The Economic Survey, Assam 2025–26 reports a Protected Area Network consisting of 8 National Parks and 17 Wildlife Sanctuaries, covering approximately 5,459.38 sq km, or about 6.96% of Assam's geographical area.
Assam also has four Tiger Reserves—Manas, Nameri, Kaziranga and Orang. Two of its great protected landscapes, Kaziranga National Park and Manas Wildlife Sanctuary, have been recognised as UNESCO Natural World Heritage properties since 1985.
Wetland conservation is represented internationally by Deepor Beel, Assam's Ramsar-listed Wetland of International Importance. The Ramsar site covers approximately 4,000 hectares southwest of Guwahati and is important for migratory waterbirds, fish, wetland biodiversity, flood storage and urban drainage.
This detailed guide examines the National Parks, Wildlife Sanctuaries, Tiger Reserves, Ramsar wetland, flagship wildlife, major conservation landscapes, ecological corridors and conservation challenges of Assam.

Why Assam Is Rich in Wildlife
Assam occupies a particularly important position in the biological geography of South and Southeast Asia.
Its wildlife richness is the result of several interacting geographical factors.
Varied Physiography
Assam contains:
- the Brahmaputra floodplain;
- the Barak Valley;
- Himalayan foothills;
- Karbi Anglong Plateau;
- Dima Hasao hills;
- the Barail Range;
- river islands;
- wetlands; and
- lowland rainforest.
High Rainfall
Abundant monsoon rainfall supports forests, grasslands, swamps and wetlands.
Large River Systems
The Brahmaputra and Barak systems create extensive:
- floodplains;
- sandbars;
- oxbow lakes;
- beels;
- swamps;
- riverine forests; and
- tall grasslands.
The relationship between wildlife and the Brahmaputra floodplain is explored further in the Brahmaputra River Basin of Assam.
Biogeographical Connectivity
Assam lies between the:
- Eastern Himalaya;
- Brahmaputra Valley;
- Indo-Myanmar hill systems; and
- Indian subcontinental plains.
This geographical position helps species from different biogeographical regions overlap within the state.
National Park, Wildlife Sanctuary, Tiger Reserve and Ramsar Site: What Is the Difference?
| Designation | Main Purpose | Important Point |
|---|---|---|
| National Park | Strong protection of ecosystems, wildlife and habitat | Declared under the Wild Life (Protection) Act; generally stricter protection than a sanctuary |
| Wildlife Sanctuary | Protection of wildlife and habitat | Certain regulated rights or uses may exist depending on legal settlement and management |
| Tiger Reserve | Landscape-scale tiger and habitat conservation | Contains core / critical tiger habitat and buffer or peripheral area |
| Ramsar Site | International recognition of an important wetland | International wetland designation; not itself the same legal category as a National Park or Wildlife Sanctuary |
| UNESCO World Heritage Site | Recognition of Outstanding Universal Value | International heritage designation that may overlap existing protected areas |
National Parks of Assam
The Assam Economic Survey 2025–26 reports eight National Parks.
| National Park | Broad Region | Key Habitat / Significance | Special Status |
|---|---|---|---|
| Kaziranga | Central Brahmaputra floodplain | Tall grassland, wetlands, riverine woodland; major rhino landscape | Tiger Reserve; UNESCO World Heritage Site |
| Manas | Himalayan foothills, western Assam | Forest-grassland mosaic; rare and threatened wildlife | Tiger Reserve; UNESCO World Heritage property |
| Nameri | Northern Sonitpur foothills | Foothill forest and Jia-Bharali river system | Tiger Reserve |

| Sikhna Jwhwlao* | Kokrajhar-Chirang, Indo-Bhutan landscape | Forest corridor adjoining western protected landscapes | Counted as 8th park by Economic Survey; preliminary notification legal note applies |
1. Kaziranga National Park
Kaziranga National Park is Assam's best-known protected area and one of the world's most important conservation landscapes for the greater one-horned rhinoceros.
It lies along the Brahmaputra floodplain and contains a constantly changing mosaic of:
- tall elephant grass;
- short grasslands;
- beels and wetlands;
- sandbars;
- river channels;
- swamps;
- riverine woodland; and
- semi-evergreen forest patches.
Important Wildlife
Kaziranga supports:
- greater one-horned rhinoceros;
- Bengal tiger;
- Asian elephant;
- wild water buffalo;
- eastern swamp deer;
- hog deer;
- wild boar;
- Gangetic river dolphin; and
- rich resident and migratory birdlife.
International Importance
Kaziranga was inscribed as a UNESCO Natural World Heritage Site in 1985 and is also a Tiger Reserve.
The protected floodplain is ecologically connected with the Karbi Anglong hills to the south, which provide essential high-ground refuges and wildlife movement routes during severe Brahmaputra floods.
2. Manas National Park
Manas lies along the Himalayan foothills of western Assam beside Bhutan.
Its landscapes include:
- alluvial grasslands;
- semi-evergreen forests;
- moist deciduous forests;

Manas supports globally important populations of:
- Bengal tiger;
- greater one-horned rhinoceros;
- Asian elephant;
- wild water buffalo;
- pygmy hog;
- golden langur;
- swamp deer;
- hispid hare; and
- Bengal florican.
The UNESCO World Heritage property itself covers 39,100 hectares and forms part of the much larger Manas conservation landscape.
Manas was inscribed on the UNESCO World Heritage List in 1985 and is also one of India's original Project Tiger landscapes.
3. Nameri National Park
Nameri National Park lies at the foothills of Arunachal Pradesh and is closely associated with the Jia-Bharali river system.
The park protects:
- semi-evergreen forests;
- moist deciduous forest;
- riverine habitat;
- grassland; and
- foothill streams.
Important wildlife includes elephant, tiger, gaur, sambar, barking deer, wild boar and numerous forest and riverine birds.
Nameri is especially important because it forms part of a larger transboundary ecological landscape with forests of adjoining Arunachal Pradesh.
4. Orang National Park
Orang National Park protects an important stretch of Brahmaputra north-bank floodplain.
Its habitat includes:
- tall grasslands;
- wetlands;
- river channels;
- woodland; and
- seasonally flooded lowlands.
Orang supports greater one-horned rhinoceros, tiger, elephant, hog deer, wild boar and diverse wetland birds.
Its ecological similarity to Kaziranga has sometimes resulted in the popular description of Orang as a smaller counterpart of the larger Kaziranga floodplain ecosystem.
Orang became Assam's fourth Tiger Reserve landscape and is particularly important for conserving tiger-rhino-grassland habitat on the north bank of the Brahmaputra.
5. Dibru-Saikhowa National Park
Dibru-Saikhowa National Park occupies a dynamic floodplain landscape of Upper Assam near the confluence zone of major rivers.
Its ecosystem includes:
- river channels;
- sandbars;
- wetlands;
- grasslands;
- swamp vegetation;
- semi-evergreen forests; and
- river islands.
The park supports rich birdlife, wetland fauna, primates and other mammals.
Its constantly changing channels and floodplain vegetation illustrate the ecological importance of natural river dynamics in Assam.
6. Dihing Patkai National Park
Dihing Patkai National Park protects one of Assam's most important remaining lowland tropical wet evergreen rainforest landscapes.
Located in the Dibrugarh-Tinsukia region, its vegetation forms part of the broader Upper Assam rainforest system.
Wildlife includes:
- Asian elephant;
- hoolock gibbon;
- slow loris;
- macaques;
- clouded leopard;
- other wild cats;
- hornbills; and
- numerous rainforest birds, reptiles and butterflies.
The park's importance becomes clearer when viewed alongside the detailed account of the biodiversity of Assam.
7. Raimona National Park
Raimona National Park lies in western Assam within the Bodoland Territorial Region.
It forms part of the larger transboundary forest landscape associated with Bhutan.
Important wildlife includes:
- golden langur;
- Asian elephant;
- gaur;
- tiger;
- clouded leopard;
- hornbills; and
- numerous butterflies.
Raimona is particularly important because western Assam's foothill forests connect with protected forests across the Bhutan border.
8. Sikhna Jwhwlao National Park
Sikhna Jwhwlao is the newest protected landscape counted as Assam's eighth National Park in the Economic Survey 2025–26.
The proposed park lies in Kokrajhar and Chirang districts of the Bodoland Territorial Region and covers approximately 316.29 sq km.
Its geographical importance comes from its position along the Indo-Bhutan landscape and its connection with other protected forests of western Assam.
The landscape supports important wildlife such as:
- golden langur;
- Asian elephant;
- tiger;
- other large mammals;
- forest birds; and
- exceptionally diverse butterfly communities.

Important Wildlife Sanctuaries of Assam
Pobitora Wildlife Sanctuary
Pobitora is a compact floodplain grassland and wetland landscape known particularly for its greater one-horned rhinoceros population.
Its habitats also support:
- wild boar;
- feral and domestic-interface buffalo populations;
- jackals;
- wetland birds; and
- seasonally flooded grassland fauna.
Hollongapar Gibbon Wildlife Sanctuary
Hollongapar protects an important remnant of Upper Assam semi-evergreen forest.
It is best known for the western hoolock gibbon, India's only ape.
The sanctuary also supports several macaque and langur species, making it one of India's particularly important primate landscapes.
Chakrasila Wildlife Sanctuary
Chakrasila in western Assam is strongly associated with the conservation of the golden langur.
Its hill forest, valleys and adjoining community landscapes form part of a larger western Assam primate habitat.
Panidehing Wildlife Sanctuary
Panidehing protects important floodplain wetland habitat in Upper Assam.
It is particularly significant for:
- resident waterbirds;
- migratory ducks;
- waders;
- wetland plants;
- fish; and
- other aquatic biodiversity.
Laokhowa-Burachapori Landscape
Laokhowa and Burachapori form an important Brahmaputra floodplain conservation landscape.
The area contains:
- grasslands;
- wetlands;
- riverine habitats;
- woodland patches; and
- important wildlife corridors.
Amchang Wildlife Sanctuary
Amchang lies immediately beside the rapidly growing Guwahati metropolitan region.
It is especially important for maintaining forest habitat and elephant movement close to Assam's largest city.
Borail Wildlife Sanctuary
Borail protects hill forests of southern Assam and forms part of the ecologically important Barail Range.
It supports tropical and subtropical vegetation, primates, carnivores and a particularly rich bird community.
Tiger Reserves of Assam
The National Tiger Conservation Authority currently lists four Tiger Reserves in Assam:
- Manas Tiger Reserve
- Nameri Tiger Reserve
- Kaziranga Tiger Reserve
- Orang Tiger Reserve
A Tiger Reserve is normally larger than the National Park or other protected area at its centre because it includes both core / critical tiger habitat and buffer or peripheral areas.
Core, Buffer and Total Area of Assam's Tiger Reserves
| Tiger Reserve | Core / Critical Tiger Habitat | Buffer | Total Tiger Reserve Area |
|---|---|---|---|
| Manas | 526.22 sq km | 2,310.88 sq km | 2,837.10 sq km |
| Nameri | 320.00 sq km | 144.00 sq km | 464.00 sq km |
| Kaziranga | 625.58 sq km | 548.00 sq km | 1,173.58 sq km |
| Orang | 79.28 sq km | 413.18 sq km | 492.46 sq km |
Together, the four NTCA tiger-reserve landscapes cover approximately 4,967.14 sq km.
Ramsar Site of Assam
The Convention on Wetlands, commonly called the Ramsar Convention, recognises wetlands of international ecological importance.
Assam's currently listed Ramsar wetland is:
Deepor Beel – Ramsar Site No. 1207
It was designated on 19 August 2002.
The Ramsar site covers approximately 4,000 hectares or 40 sq km.
Deepor Beel: Assam's Ramsar Wetland
Deepor Beel is a large freshwater wetland southwest of Guwahati and occupies a former channel of the Brahmaputra River system.
It performs several ecological functions simultaneously.
Waterbird Habitat
The wetland supports large numbers of:
- resident waterbirds;
- migratory ducks;
- waders;
- storks;
- herons;
- egrets; and
- other wetland-dependent birds.
Fishery Resource
Deepor Beel supports fish and other aquatic organisms and has long contributed to local wetland-based livelihoods.
Flood and Drainage Function
The wetland is an important natural storm-water storage and drainage basin for parts of the Guwahati region.
Elephant Landscape
The wetland lies close to hill forests used by Asian elephants, making landscape connectivity around Deepor Beel ecologically important.
Major Threats
Important pressures include:
- encroachment;
- siltation;
- solid waste;
- pollution;
- disturbance;
- land-use change;
- transport infrastructure; and
- changes in natural drainage.
Deepor Beel Ramsar Site vs Deepor Beel Wildlife Sanctuary
This distinction is particularly important for geography and competitive examinations.
| Designation | Area | Meaning |
|---|---|---|
| Deepor Beel Ramsar Site | 4,000 ha / 40 sq km | Wetland of International Importance under the Ramsar Convention |
| Deepor Beel Wildlife Sanctuary | 414 ha / 4.14 sq km | Legally notified Wildlife Sanctuary covering part of the larger wetland |
Therefore, 40 sq km and 4.14 sq km are not conflicting figures. They refer to two different boundaries and conservation designations.
UNESCO World Heritage and Assam's Protected Areas
Two Assam wildlife landscapes have global World Heritage recognition.
Kaziranga National Park
Kaziranga was inscribed on the UNESCO World Heritage List in 1985.
UNESCO recognises its outstanding ecological processes and biodiversity, particularly its importance for the greater one-horned rhinoceros and other threatened species.
Manas Wildlife Sanctuary
Manas was also inscribed in 1985.
The UNESCO property covers approximately 39,100 hectares within the larger Manas protected landscape.
Its exceptional value lies in the combination of Himalayan foothill forest, river systems, alluvial grasslands and threatened wildlife.
These international designations add another conservation layer; they do not replace the legal National Park, Wildlife Sanctuary or Tiger Reserve categories.
Flagship Wildlife of Assam
The protected-area network conserves some of South Asia's most threatened and ecologically significant species.
Greater One-Horned Rhinoceros
The greater one-horned rhinoceros is one of the most recognisable symbols of Assam's wildlife conservation.
Important rhino landscapes include:
- Kaziranga National Park;
- Orang National Park;
- Pobitora Wildlife Sanctuary; and
- Manas National Park.
The species depends heavily on floodplain grasslands, wetlands, wallows, riverine woodland and access to higher ground during extreme floods.
Bengal Tiger
Tigers occur across several protected landscapes of Assam, but the four formally notified Tiger Reserves provide the core national conservation framework.
Healthy tiger populations depend on:
- large connected habitats;
- abundant prey;
- low poaching pressure;
- forest and grassland integrity;
- buffer-zone management; and
- wildlife corridors.
Protecting the tiger therefore protects entire ecosystems rather than only a single species.
Asian Elephant
Assam supports important Asian elephant populations across:
- Upper Assam forests;
- Karbi Anglong;
- Sonitpur foothills;
- Manas-Raimona landscape;
- Amchang and adjoining hills;
- Dihing Patkai;
- Nameri; and
- other forest corridors.
Elephants require much larger landscapes than individual protected areas, which makes corridors between forests particularly important.
Primates of Assam's Protected Areas
Assam has exceptional primate diversity.
Important species include:
- western hoolock gibbon;
- golden langur;
- capped langur;
- Assamese macaque;
- rhesus macaque;
- pig-tailed macaque;
- stump-tailed macaque; and
- Bengal slow loris.
Hollongapar Gibbon Wildlife Sanctuary is particularly important for hoolock gibbon conservation, while Chakrasila and western Assam forests are strongly associated with the golden langur.
Grassland Wildlife
Brahmaputra floodplain grasslands are among the most important wildlife habitats in Assam.
They support species including:
- greater one-horned rhinoceros;
- wild water buffalo;
- swamp deer;
- hog deer;
- pygmy hog;
- hispid hare;
- Bengal florican; and
- numerous grassland birds.
Seasonal flooding, sediment deposition and controlled ecological succession help maintain these open grassland systems.
Bird Diversity of Assam's Protected Areas
Assam's forests, wetlands and grasslands support exceptionally diverse bird communities.
Important species and groups include:
- Greater Adjutant;
- White-winged Wood Duck;
- Bengal Florican;
- Great Hornbill;
- Wreathed Hornbill;
- Oriental Pied Hornbill;
- raptors;
- waterfowl;
- woodpeckers;
- pheasants;
- waders; and
- migratory wetland birds.
Deepor Beel, Panidehing and the numerous wetlands inside Kaziranga, Manas and other protected landscapes are particularly valuable for aquatic and migratory birds.
River and Wetland Wildlife
Wildlife conservation in Assam extends beyond forests and grasslands.
The Brahmaputra and its tributaries support:
- Gangetic river dolphin;
- freshwater turtles;
- otters;
- fish;
- waterbirds;
- reptiles;
- amphibians; and
- aquatic plants.
River channels also connect otherwise separate protected landscapes.
Wildlife Corridors and Landscape Connectivity
Protected areas cannot conserve large wildlife populations effectively if they become isolated ecological islands.
Wildlife corridors allow animals to move between:
- feeding areas;
- breeding habitat;
- seasonal ranges;
- high ground;
- river valleys; and
- neighbouring forests.
Kaziranga-Karbi Anglong Connectivity
During major floods, wildlife from the Kaziranga floodplain moves toward the higher terrain of Karbi Anglong.
Maintaining safe movement routes across roads and developed areas is therefore crucial.
Manas-Bhutan Landscape
Manas forms part of a transboundary ecological landscape with Bhutan.
Raimona-Sikhna-Bhutan Landscape
Western Assam's protected forests form a larger conservation system linked with Bhutanese forests.
Nameri-Arunachal Landscape
Nameri is ecologically connected with forests in neighbouring Arunachal Pradesh.
Brahmaputra Floodplain Protected-Area Landscape
The Brahmaputra floodplain protected-area system includes landscapes such as:
- Kaziranga;
- Orang;
- Pobitora;
- Laokhowa;
- Burachapori;
- Dibru-Saikhowa;
- Deepor Beel; and
- numerous riverine wetlands and grasslands.
These areas depend on natural processes such as:
- flooding;
- erosion;
- sediment deposition;
- channel migration;
- wetland formation; and
- grassland succession.
Floods can cause temporary wildlife mortality but are also fundamental to the long-term functioning of the floodplain ecosystem.
Himalayan Foothill Protected Areas
Nameri, Manas, Raimona, Sikhna Jwhwlao and several sanctuaries occupy or connect with Himalayan foothill forests.
These landscapes are important because they:
- receive heavy rainfall;
- contain forest-river mosaics;
- connect Assam with Bhutan and Arunachal Pradesh;
- support elephant and tiger movement; and
- contain high bird and butterfly diversity.
Upper Assam Rainforest Protected Areas
Upper Assam contains some of the state's most important remaining tropical wet evergreen forests.
Protected landscapes include:
- Dihing Patkai National Park;
- Hollongapar Gibbon Wildlife Sanctuary;
- Bherjan-Borjan-Podumoni Wildlife Sanctuary;
- Dibru-Saikhowa floodplain system; and
- other Reserve Forests and elephant corridors.
These landscapes protect Hollong-dominated rainforest and numerous primates, hornbills, wild cats and forest specialists.
Western Assam and Bodoland Conservation Landscape
Western Assam contains one of the state's largest connected wildlife landscapes.
Important protected areas include:
- Manas National Park;
- Raimona National Park;
- Sikhna Jwhwlao landscape;
- Chakrasila Wildlife Sanctuary;
- Bornadi Wildlife Sanctuary; and
- other Reserve Forests and community forests.
The landscape is particularly important for:
- golden langur;
- Asian elephant;
- tiger;
- gaur;
- pygmy hog;
- hispid hare;
- hornbills; and
- transboundary wildlife movement.
Major Threats to Wildlife and Protected Areas of Assam
Habitat Fragmentation
Roads, railways, settlements, industries and other development can divide natural habitat into smaller blocks.
Poaching and Illegal Wildlife Trade
Strong enforcement remains necessary to protect high-value threatened species.
Wetland Degradation
Wetlands can be affected by:
- encroachment;
- pollution;
- siltation;
- waste dumping;
- drainage alteration; and
- disturbance.
Invasive Species
Invasive plants may alter grasslands, wetlands and forest understories and reduce native habitat quality.
Mining and Resource Extraction
Mining, quarrying and hydrocarbon development near sensitive landscapes require careful assessment because they may affect:
- wildlife movement;
- water quality;
- forest cover;
- noise levels; and
- habitat continuity.
Linear Infrastructure
Highways, railways, transmission lines and pipelines can increase wildlife mortality and fragment migration routes if not designed with ecological safeguards.
Floods and Wildlife Conservation
Floods are a natural component of Assam's riverine ecosystems.
In Kaziranga and other floodplain landscapes, annual floods:
- replenish wetlands;
- deposit fertile sediments;
- limit woody vegetation;
- maintain grasslands; and
- renew aquatic habitats.
Severe floods, however, may cause wildlife mortality and force large numbers of animals toward higher ground.
This makes safe corridors between floodplain protected areas and adjoining uplands essential.
Human-Wildlife Conflict in Assam
Wildlife frequently moves beyond formally protected boundaries.
This is particularly true for:
- elephants;
- tigers;
- leopards;
- rhinoceroses;
- wild buffalo; and
- other large mammals.
Conflict may involve:
- crop damage;
- property damage;
- livestock loss;
- human injury;
- wildlife mortality; and
- competition for space and resources.
Long-term solutions require landscape planning, early-warning systems, corridor protection, appropriate compensation and community participation.
Wildlife Conservation in Assam
Protected-Area Management
National Parks and Wildlife Sanctuaries provide the legal foundation for habitat conservation.
Project Tiger
Four Tiger Reserves extend tiger conservation beyond individual National Park boundaries into larger core-buffer landscapes.
Rhino Conservation
Protection, habitat management and population restoration have helped maintain rhinoceros populations across several Assam landscapes.
Anti-Poaching
Conservation measures include:
- forest camps;
- patrolling;
- surveillance;
- intelligence networks;
- special protection forces;
- river patrols; and
- coordination among enforcement agencies.
Habitat Management
Management may involve:
- grassland management;
- wetland restoration;
- controlled burning where ecologically appropriate;
- invasive-plant control;
- water-body management;
- forest restoration; and
- corridor conservation.
Community Participation
Communities living around protected landscapes are essential partners in:
- ecotourism;
- habitat protection;
- conflict mitigation;
- anti-poaching intelligence;
- alternative livelihoods; and
- sustainable resource use.
Economic and Ecological Importance of Protected Areas
Biodiversity Conservation
Protected areas preserve species, habitats and genetic diversity.
Tourism
Wildlife tourism generates employment through:
- safaris;
- accommodation;
- guides;
- transport;
- restaurants;
- handicrafts; and
- local services.
Water and Watershed Protection
Forested protected areas help regulate runoff and protect streams and river catchments.
Carbon Storage
Forests and wetlands store carbon and help regulate local climate.
Floodplain Function
Grasslands and wetlands store floodwater and support sediment and nutrient cycles.
Scientific Research
Assam's protected areas provide valuable landscapes for ecological, zoological, botanical and climate research.
Wildlife & Protected Areas of Assam: Important Facts for APSC & ADRE

When was Deepor Beel declared a Ramsar Site?
Deepor Beel was designated as a Wetland of International Importance on 19 August 2002.
What is the area of Deepor Beel Ramsar Site?
The Ramsar boundary covers 4,000 hectares, or approximately 40 sq km.
Why is Deepor Beel Wildlife Sanctuary only 4.14 sq km?
The Wildlife Sanctuary covers only a legally notified 414-hectare portion of the wider 4,000-hectare Ramsar wetland. The two figures describe different boundaries.
Which protected area is famous for the one-horned rhinoceros?
Kaziranga National Park is globally famous for conserving the greater one-horned rhinoceros. Rhinoceroses also occur in Orang, Pobitora and Manas.
Which sanctuary is famous for hoolock gibbon?
Hollongapar Gibbon Wildlife Sanctuary in Jorhat is particularly important for the western hoolock gibbon.
Which sanctuary is famous for the golden langur?
Chakrasila Wildlife Sanctuary is one of Assam's best-known protected landscapes for the golden langur.
Which National Park of Assam is famous for tropical rainforest?
Dihing Patkai National Park protects important lowland tropical wet evergreen rainforest in Upper Assam.
Which protected areas share ecological connections with Bhutan?
Manas, Raimona and the Sikhna Jwhwlao landscape form important parts of the western Assam-Indo-Bhutan conservation system.
Why are wildlife corridors important in Assam?
Wildlife corridors allow elephants, tigers, rhinoceroses and other animals to move between forests, floodplains, high ground, feeding areas and breeding habitats. They are particularly important around Kaziranga-Karbi Anglong, Manas-Bhutan and other transboundary landscapes.
Conclusion
The wildlife and protected areas of Assam form one of the most important conservation networks in India.
The latest Assam Economic Survey reports eight National Parks and 17 Wildlife Sanctuaries within a Protected Area Network of approximately 5,459.38 sq km, equivalent to about 6.96% of the state's geographical area.
These protected areas represent remarkably different ecological landscapes. Kaziranga and Orang conserve Brahmaputra floodplain grasslands; Manas, Nameri and Raimona protect Himalayan foothill systems; Dihing Patkai protects tropical rainforest; Dibru-Saikhowa protects a dynamic riverine floodplain; and Deepor Beel represents internationally important wetland habitat.
The four Tiger Reserves—Manas, Nameri, Kaziranga and Orang—expand conservation beyond individual park boundaries by combining core habitats with broader buffer landscapes.
Assam also possesses exceptional international conservation recognition. Kaziranga and Manas are UNESCO Natural World Heritage properties, while Deepor Beel is a Ramsar Wetland of International Importance.
These landscapes protect much more than charismatic wildlife. Forests regulate water and store carbon, wetlands absorb floodwater, riverine grasslands maintain unique ecological communities and wildlife corridors allow animals to move between otherwise isolated habitats.
Long-term conservation therefore cannot depend only on drawing protected-area boundaries. It also requires protection of wildlife corridors, wetlands, river systems, forest buffers, high-ground refuges and community landscapes outside formal parks and sanctuaries.
Assam's conservation challenge is especially complex because its wildlife-rich landscapes are also crossed by rivers, roads, railways, settlements, plantations, farms and industrial infrastructure.
Maintaining ecological connectivity while supporting human livelihoods will therefore remain central to the future of wildlife conservation in Assam.

Research Note: Protected-area statistics may vary among documents because National Park additions, Tiger Reserve core and buffer areas, Ramsar boundaries and Wildlife Sanctuary boundaries represent different legal or ecological units. These areas should not be added together without accounting for overlap. The latest Economic Survey counts eight National Parks, while the Forest Department's publicly available Sikhna Jwhwlao document is a preliminary notification; this distinction has therefore been retained throughout the article.
