What Makes Assam a Biodiversity Hotspot?
Assam forms part of the Eastern Himalaya and Indo-Burma biodiversity regions. Its unique location supports high species richness. The Brahmaputra and Barak river systems also create wetlands, floodplains, grasslands, and riverine forests.
The Assam government notes that the state has many wetlands, including Deepor Beel, Chandubi, Son Beel, and several other important beels and hoars. These wetlands support fish, birds, reptiles, mammals, and local livelihoods.
Major reasons behind Assam’s biodiversity richness:
- Firstly, Assam has tropical forests, grasslands, wetlands, and river ecosystems.
- Secondly, the Brahmaputra floodplain supports fertile and diverse habitats.
- Moreover, the state lies near the Eastern Himalayan biodiversity region.
- Furthermore, it provides habitat for many endangered and endemic species.
- Notably, it acts as a wildlife corridor between India, Bhutan, Arunachal Pradesh, and other Northeast regions.
Therefore, Assam’s biodiversity has both ecological and exam importance.

Recently, concerns over tree felling and ecological stress near Deepor Beel again brought the wetland into the news. The forest department promised to plant ten times the number of felled trees near Deepor Beel.
Important Wildlife Species of Assam
Assam has many important wildlife species. Some are endangered, while others are iconic symbols of the state.
Which are the Key Species on which APSC frequently ask questions?
The most important key species on which APSC frequently asks questions are as follow:
- One-horned rhinoceros
- Royal Bengal tiger
- Ganges Softshell Turtle
- Asian elephant
- Wild water buffalo
- Eastern swamp deer
- Gangetic river dolphin
- Pygmy hog
- Golden langur
- Western hoolock gibbon
- Greater adjutant stork
- Bengal florican
- White-winged wood duck
The Assam State Biodiversity Board notes that Assam has around 950 bird species, which represents 53.5% of bird species found in the Indian subcontinent. Moreover, out of 8 species of Gangetic Softshell turtle, 5 are found in Kaziranga national park.
Therefore, Assam is highly important for avian biodiversity and wetland conservation.
One-Horned Rhinoceros in Assam
The one-horned rhinoceros is Assam’s most iconic wildlife species. Kaziranga is the main stronghold of this species. As per the recent data, Kaziranga has 2,613 greater one-horned rhinoceroses. It also supports elephants, wild water buffaloes, swamp deer, and other wildlife. Moreover, Pobitora Wildlife Sanctuary holds the highest density of Greater one Horned Rhinoceros in the country.
Threats to rhinos:
- Poaching for horn
- Flood-related deaths
- Habitat loss
- Disease risk
- Human-wildlife conflict
However, strong anti-poaching efforts have helped improve rhino protection.
Endangered Species in Assam for APSC
Endangered species in Assam are important for Prelims, Mains, and current affairs.
Important endangered and threatened species:
- Pygmy Hog: Found in tall grassland habitats.
- Golden Langur: Found near the Assam-Bhutan landscape.
- Western Hoolock Gibbon: India’s only ape.
- Bengal Florican: A critically endangered grassland bird.
- Gangetic River Dolphin: Found in Brahmaputra river system.
- Ganges Softshell Turtle: Important freshwater turtle species.
Moreover, Assam recently achieved a conservation milestone by releasing India’s first satellite-tagged Ganges softshell turtle in the Brahmaputra at Kaziranga. This shows the growing use of technology in wildlife conservation.
Assam’s Wetlands and River Ecosystems
Assam’s wetlands play a major role in biodiversity conservation. The Brahmaputra and Barak river systems create several wetlands, beels, oxbow lakes, marshes, and floodplain ecosystems. Notably, Deepor Beel is the only Ramsar site in Assam.
Importance of wetlands:
- Firstly, they support fish diversity.
- Secondly, they provide habitat for migratory birds.
- Thirdly, they reduce flood impact.
- Moreover, they support local communities.
- Furthermore, they recharge groundwater and act as carbon sinks.
However, wetlands face threats from encroachment, siltation, pollution, overfishing, and urban expansion.
What are the major threats to Assam’s Biodiversity and Wildlife?
Assam’s biodiversity faces several serious threats. Aspirants should prepare this section for Mains answers specifically for GS-5.
Key threats:
- Habitat loss: Roads, mining, settlements, and agriculture reduce wildlife habitats.
- Floods: Annual floods affect Kaziranga and other floodplain habitats.
- Poaching: Illegal wildlife trade targets rhinos, turtles, birds, and other animals.
- Human-wildlife conflict: Elephants, leopards, and other animals often enter human settlements.
- Wetland degradation: Pollution and encroachment damage Deepor Beel and other wetlands.
- Climate change: Changing rainfall and flood patterns affect ecosystems.
- Invasive species: Alien plants reduce native grasslands and wetlands.
In May 2026, Golaghat Police launched anti-poaching operations in six critical areas to protect wildlife and counter illegal wildlife trade networks.
Assam Floods and Wildlife Conservation
Floods are natural to Assam’s riverine ecosystem. However, extreme floods can harm wildlife.
Kaziranga faces floods almost every year. Floods help renew grasslands, but severe floods can kill animals and force them to move towards highlands and roads. In 2024, floods in Assam killed many animals, including one-horned rhinos, at Kaziranga.
Conservation measures during floods:
- Build and protect highlands.
- Control vehicle speed near animal corridors.
- Use rescue teams.
- Monitor animal movement.
- Strengthen community support.
- Protect forest corridors.
Therefore, flood management is also wildlife management in Assam.
Human-Wildlife Conflict in Assam
Human-wildlife conflict is a major environmental issue in Assam. Elephants, leopards, wild boars, rhinos, and other animals often move into villages and farms.
Causes of conflict:
- Shrinking forest cover has forced many wild animals to move out of their natural habitats in search of food and shelter.
- Furthermore, blocked elephant corridors and habitat fragmentation have disrupted the traditional movement routes of elephants and other wildlife species.
- In addition, the rapid expansion of human settlements near forests has increased encounters between humans and wild animals.
- Seasonal floods in Assam also push animals out of forests and protected areas into nearby villages and agricultural lands.
Therefore, human-wildlife conflict remains an important topic for APSC and UPSC preparation under environment, biodiversity, and conservation issues.
Solutions:
- Authorities should restore and protect wildlife corridors to ensure the safe movement of animals between forest areas.
- Moreover, the government should use early warning systems to alert nearby villages about animal movement.
- Furthermore, officials must provide quick and fair compensation to people affected by crop loss, livestock damage, or property destruction.
- In addition, conservation agencies should promote community awareness programmes about wildlife behaviour and conflict management.
- Farmers should reduce the cultivation of crops that strongly attract elephants and other wild animals near forest boundaries.
- Authorities should also use solar fencing carefully and legally to minimise human-wildlife conflict without harming animals.
Conservation Laws and Institutions for Assam Biodiversity
Aspirants should link Assam biodiversity with national environmental laws.
Important laws and institutions:
- Wildlife Protection Act, 1972
- Forest Conservation Act, 1980
- Environment Protection Act, 1986
- Biological Diversity Act, 2002
- Assam State Biodiversity Board
- National Biodiversity Authority
- Biodiversity Management Committees
- People’s Biodiversity Registers
The Assam State Biodiversity Board works under the Environment, Forest and Climate Change Department of Assam and deals with biodiversity conservation, awareness, documentation, and sustainable use.
Assam Biodiversity Current Affairs for APSC
APSC aspirants must connect biodiversity topics with current affairs. Many questions come from recent wildlife events, conservation projects, and government initiatives.
Current affairs areas to follow:
