Biodiversity of Nagaland: Flora, Fauna and Conservation
The biodiversity of Nagaland extends from forest canopies and mountain streams to cultivated terraces, village woodlands and seasonal bird-roosting sites. Its importance lies not only in the variety of plants and animals found here, but also in the relationships that connect forests, water, soil and local livelihoods.
Nagaland forms part of the Indo-Burma biodiversity hotspot. Changes in elevation and climate create contrasting conditions within a relatively small area, supporting different biological communities across the hills and valleys. Conservation must therefore protect a network of habitats, including land managed by villages, clans and individual households.

Why Is Nagaland Rich in Biodiversity?
Variation in Elevation and Climate
A journey from a warm valley to a cool mountain ridge crosses changing ecological conditions. Temperature, humidity, wind exposure and the duration of wet conditions influence which plants can grow and which animals can use a habitat.
This variation creates opportunities for different communities to occur close together. However, habitat boundaries are gradual and irregular: vegetation does not change at an identical elevation on every slope.
Connections with Neighbouring Landscapes
Wildlife habitats continue beyond administrative borders. Forests and river catchments link Nagaland with surrounding landscapes, making ecological connectivity an important consideration in conservation planning.
A protected forest can lose value for some species if the surrounding land becomes difficult to cross. Retaining vegetation between larger habitat patches helps maintain movement and access to seasonal resources.
Different Forms of Biodiversity
Biodiversity includes more than a list of species. It also includes genetic variation within species and the variety of ecosystems they occupy.
For Nagaland, this means that native forests, locally maintained crop varieties and the biological communities of streams all deserve attention. Protecting a familiar bird while neglecting its food plants, nesting conditions or water sources would address only part of the ecological system.
Major Habitats and Vegetation of Nagaland
The following groups provide a geographical overview. They are not a district-level vegetation map, and their composition varies with local conditions and land-use history.
| Habitat | General Characteristics | Conservation Importance |
|---|---|---|
| Warm lower-elevation forests | Forested foothills and valleys with relatively warm conditions. | Maintain canopy habitats and connections between forest patches. |
| Subtropical hill forests | Wooded slopes with changing moisture and temperature conditions. | Support diverse plant communities and protect catchments. |
| Cooler mountain vegetation | High-elevation forests, shrubs and open vegetation. | Provide habitats for species adapted to cooler environments. |
| Bamboo and regenerating vegetation | Bamboo stands and vegetation recovering after disturbance. | Supply resources and form part of the wider habitat mosaic. |
| Streams and riverside habitats | Flowing water, banks and associated vegetation. | Connect aquatic and terrestrial food webs. |
| Village and agricultural landscapes | Fields, terraces, home gardens and tree-based farming systems. | Maintain cultivated diversity and opportunities for habitat protection. |
Different habitats are not interchangeable. A bamboo stand, plantation and mature mixed forest may all appear green, but they can differ substantially in tree diversity, nesting opportunities and understory conditions.
Floral Diversity of Nagaland
What Official Plant Inventories Report
The Nagaland State Biodiversity Board’s published overview reports approximately 2,431 flowering-plant species and about 360 orchid species. These are figures from the Board’s overview, rather than the results of a new survey conducted for this article.
Inventories change as additional areas are surveyed and scientific names are revised. Counts from different publications should therefore retain their source context rather than being combined into a supposedly exact current total.
Orchids and Their Habitats
Orchid conservation requires attention to the conditions in which plants grow. Some orchids occupy tree surfaces, while others grow on the ground. An orchid growing on a tree is not necessarily parasitic: the tree may simply provide physical support.
Removing plants from the wild can damage small populations. Protecting host trees, humid forest conditions and the surrounding habitat is more useful than treating orchids only as ornamental objects.
Rhododendrons, Ferns and Other Forest Plants
Rhododendrons, ferns, bamboos and lichens are among the plant groups highlighted in Nagaland’s forest-policy account. Their ecological roles differ, from providing vegetation structure to participating in forest-floor and canopy communities.
The smaller components of vegetation also matter. Seedlings indicate future forest recruitment, while shrubs and ground vegetation provide cover and resources that large trees alone cannot replace.
Medicinal and Useful Plants
Plant diversity supports knowledge about food, household materials and traditional uses. Conservation should retain both the biological resource and the community knowledge associated with it.
Harvesting methods influence sustainability. Removing an entire plant or its roots can have different consequences from carefully collecting a renewable part. Documentation of traditional use should also remain distinct from claims of medically proven effectiveness.
Faunal Diversity of Nagaland
Forest Mammals
Government descriptions of the Peren landscape record mammals including hoolock gibbons and other forest wildlife. Species records should be interpreted by location: an animal reported from a particular forest is not necessarily widespread across Nagaland.
For canopy-dwelling animals, forest continuity can be especially important. Large gaps alter movement routes and access to food. Ground-dwelling animals may respond differently, depending on vegetation cover, disturbance and hunting pressure.
Historical records also differ from recent observations. A responsible wildlife account should avoid turning an old occurrence report into a claim of a healthy present-day population.
Blyth’s Tragopan and Other Birds
Blyth’s tragopan is Nagaland’s state bird and a prominent focus of conservation associated with Khonoma. Its significance helps draw attention to the protection of forest habitats and the reduction of hunting pressure.
Bird conservation also requires a wider view. Nesting trees, understory vegetation, feeding areas and seasonal movements all influence whether a landscape can support different bird communities.
Aquatic Life and Smaller Animals
Streams support biological communities that are easily overlooked in discussions centred on forests. Changes in sediment, water quality and streamside vegetation can affect these habitats even when the source of disturbance lies farther uphill.
Insects and other small organisms contribute to pollination, decomposition and food webs. Their ecological importance is not proportional to their visibility: a functioning forest depends on many interactions that visitors rarely notice.
Amur Falcon Migration and Conservation
The seasonal arrival of Amur falcons is one of Nagaland’s best-known wildlife events. The Doyang landscape is associated with major stopover roosts used during their long-distance migration.
A migration stopover is more than a place where birds can be photographed. It provides an opportunity to rest and obtain food before continuing a demanding journey. Disturbance or loss of safe roosts can therefore affect birds beyond the local area.
Following the widely documented hunting crisis in 2012, conservation efforts brought together local communities, the Forest Department, conservation organisations and researchers. The Convention on Migratory Species documents coordinated work beginning in 2013.
This experience demonstrates why local participation matters. Protection becomes more effective when residents help safeguard roosts and recognise the value of the migration. Visitors should keep their distance, avoid disturbing roosting birds and follow local conservation arrangements.
Important Conservation Landscapes in Nagaland
Ntangki National Park
Ntangki National Park, also known as Intanki, is an important forest conservation area in Peren. The district administration describes it as covering approximately 200 square kilometres.
Its conservation value extends beyond individual animal sightings. Maintaining the forest protects a setting in which plants, mammals, birds, reptiles and other organisms interact. Habitat condition and connectivity are therefore as important as the park’s name or area.
Fakim and the Saramati Landscape
Fakim Wildlife Sanctuary lies near the India–Myanmar border. The broader Fakim–Saramati landscape is recognised for its biodiversity importance and its mountain setting.
Conservation here benefits from attention to the surrounding forests as well as the sanctuary itself. A small protected area cannot be understood independently of the land around it, particularly where wildlife movements or catchments cross its boundary.
Puliebadze, Dzukou and Japfu
The Puliebadze–Dzukou–Japfu landscape is recognised in the Key Biodiversity Areas database. The site account also identifies Puliebadze as an important catchment for Kohima.
This illustrates the connection between conservation and everyday needs. Protecting upland vegetation can support both habitat quality and catchment management. Visitor pressure, litter and fire require careful attention in accessible mountain landscapes.
Khonoma
Khonoma is an important example of community-led conservation associated with the Khonoma Nature Conservation and Tragopan Sanctuary. Its significance lies in local decisions about hunting and forest protection.
The word “sanctuary” in the name of a community initiative should not automatically be treated as proof that it has the same legal designation as a notified wildlife sanctuary. Conservation initiatives can have different governance arrangements while still making valuable contributions.
Other Protected Forest Areas
Nagaland’s 2015 Environment and Forest Policy also lists Rangapahar and Singphan among the state’s wildlife sanctuaries. This historical policy inventory should not be treated as a complete, newly verified list of every current conservation designation.
Community Conservation and Agricultural Biodiversity
Local Institutions and Forest Stewardship
Nagaland’s forest policy recognises the importance of community and individual landholding. Conservation consequently depends on cooperation with the people who make decisions about land and resources.
Locally agreed protection, monitoring and harvesting arrangements can complement government conservation programmes. Such measures work best when responsibilities are clear and the benefits and costs are understood by the community.
Jhum Landscapes
Jhum should be assessed through its management, including cultivation frequency, fallow duration and the condition of surrounding vegetation. Different stages of cultivation and recovery create different habitats.
Shortened recovery periods can increase pressure on soil and vegetation. However, treating every jhum field as ecologically identical overlooks important differences between farming systems and local practices.
Alder-Based Farming and Cultivated Diversity
Research from Khonoma documents alder-based farming alongside community forest. A 2025 comparison found greater tree diversity in the sampled community forest, while soil organic carbon was higher in the sampled alder-based jhum system.
The distinction matters: agricultural systems can provide valuable ecological functions without replacing all the biodiversity of natural forests. Maintaining both cultivated landscapes and protected native habitats supports a broader range of needs.
People’s Biodiversity Registers
People’s Biodiversity Registers document local biological resources and associated knowledge. They can help connect community observations with conservation planning.
Useful records distinguish confirmed observations from uncertain identifications and note where and when information was collected. Sensitive knowledge should be documented with the participation and agreement of its holders.
Major Threats to Biodiversity
- Habitat fragmentation: Breaking continuous vegetation into isolated patches can restrict wildlife movement and change conditions along forest edges.
- Hunting and wildlife collection: Removing animals can reduce populations even where tree cover remains.
- Unsustainable plant harvesting: Repeated collection can affect regeneration, particularly where whole plants are removed.
- Fire and repeated disturbance: Damage depends on its timing, intensity and the habitat affected.
- Degradation of streams: Sediment and pollution can transmit the effects of land disturbance into aquatic ecosystems.
- Poorly managed tourism: Noise, litter and disturbance at sensitive sites can undermine conservation benefits.
Tree cover alone is therefore an incomplete measure of biodiversity. A wooded area may retain its canopy while losing animals, plant diversity or successful regeneration.
Priorities for Biodiversity Conservation
The following priorities bring habitat protection and local stewardship together:
- Protect native habitat quality: Retain mature trees, understory vegetation and natural regeneration.
- Maintain ecological connections: Consider forests, rivers and neighbouring land uses together.
- Support community decisions: Develop conservation arrangements with local institutions and knowledge holders.
- Monitor populations and habitats: Record changes rather than relying indefinitely on old species lists.
- Manage resource use carefully: Match harvesting and restoration to the biology of the resource.
- Make nature tourism accountable: Direct benefits locally and protect wildlife from visitor disturbance.
