In addition, the Bodo community living in the area and their livelihoods, culture, and food all depend on forests to a great extent.
- Manas and other protected areas also provide regulating services. These are benefits obtained from the regulation of ecosystem processes. Manas natural habitats play a significant role in climate and disease control, water regulation, as well as pollination.
- It helps regulate floods as the water rushes down from the Himalayas. The vast green grassland in Manas is one of the most productive ecosystems and acts as a carbon sink, sequestrating huge amounts of carbon each year.
- Supporting services are necessary for the production of all other ecosystem services. The entire range of ecosystems in Manas helps in soil formation and nutrition supplements. Manas is home to thousands of species and is a haven for securing the Himalayas’ genetic diversity.
Kaziranga National Park
News: A study conducted by the Indian Institute of Tropical Meteorology, Pune, and some universities have found Kaziranga National park to be a net carbon emitter.
How Kaziranga National Park became a net carbon emitter?
The biggest factor that makes Kaziranga national park a net emitter is its unique soil. The soil is home to a large population of bacteria that release carbon dioxide as they breathe, which adds to the carbon dioxide being emanated by other organisms, including trees.
The photosynthetic activity of trees during the monsoon decreases due to increased cloud cover. Hence, the ability of the forest to absorb carbon dioxide also decreases. The situation remains the same during the post-monsoon and winter months, making the forest a net carbon emitter.
About the Kaziranga National Park: The Park has recorded a 175% increase in the number of waterfowl and winter migratory birds.
Location: It is located in the State of Assam. It is the single largest undisturbed and representative area in the Brahmaputra Valley floodplain.
UNESCO World Heritage Site: The Park was declared a National Park in 1974. In 1985, the park was designated as a World Heritage Site by UNESCO. Further, it was also declared a Tiger Reserve in 2006.
Important Bird Area: It is also recognized as an Important Bird Area by BirdLife International for the conservation of avifaunal species.
Vegetation: Due to the difference in altitude between the eastern and western areas of the park, here one can see mainly four types of vegetation’. Like alluvial inundated grasslands, alluvial savanna woodlands, tropical moist mixed deciduous forests, and tropical semi-evergreen forests. Kumbhi,
Flora: Indian gooseberry, cotton tree, and elephant Apple are among the famous trees that can be seen in the park. Also, a good variety of aquatic flora can be seen in lakes, ponds, and along the river shores.
Fauna: Along with the iconic Greater one-horned rhinoceros, the park is the breeding ground of elephants, wild water buffalo, and swamp deer. Over time, the tiger population has also increased in Kaziranga, and that’s the reason why Kaziranga was declared a Tiger Reserve in 2006.
Significance:
- It is the house of the world’s largest population of Great One-horned Rhinoceros (IUCN Status- Vulnerable).
- The title Kaziranga adopts its name from Karbi, which is the name of a woman who ruled here in ancient times.
- It is the only ancient park in Assam which wraps a vast region of numerous flora and fauna.
Area Under Wetland: The area under wetlands in Kaziranga has reduced from 8.5% of the total area to 6.7% over a period of 30 years till 1977.
Threat: However, efforts to check siltation, erosion, and fragmentation of the beels (wetlands) and removal of invasive species have breathed fresh life into the park’s ecosystem.

Fauna: It is home to species such as white-rumped vulture (Critically Endangered), ruddy shelduck (Least Concern), red-headed vulture (Critically Endangered), and Asian woolly neck (Vulnerable) among others. It is one of the best-known sites for the congregation of ruddy shelduck.
Significance: The wetland also acts as a host to several migratory birds from October to March. The reserve has a year-round availability of freshwater owing to a constant inflow of water through the Yamuna canal and Asan River.
Kakoijana Reserve Forest
News: Villagers in Assam’s Bongaigaon district have opposed a move by the State government to upgrade Kakoijana Reserve Forest to a wildlife sanctuary.
About Kakoijana Reserve Forest
Location: Bongaigaon district of Assam.
It was constituted in the year 1966 as a reserve forest. The reserve is one of the better-known homes of the golden langur (Trachypithecus geei).
Note: Golden langur is found only in Assam and Bhutan. It is listed in the world’s 25 most endangered primates.
Reason behind opposition
Once the Kakoijana Reserve Forest is converted into a wildlife sanctuary, stricter rules will be applied and this will impact the customary and traditional practices and consequently result in villagers losing their rights over the forest.
Instead, the villagers have demanded that the reserve forest should be converted into a community forest reserve using Forest Rights Act, 2006. This is because some areas inside the forest are sacred, and their sanctity should be maintained.

Amazon Rainforest
News: According to a study, more than 75% of the Amazon rainforest has been heading towards a tipping point since the early 2000s.
About Amazon Rainforest
Source: Wikipedia
These are large tropical rainforests occupying the drainage basin of the Amazon River and its tributaries in northern South America. It covers an area of 6,000,000 square km.
Comprising about 40% of Brazil’s total area, it is bounded by the Guiana Highlands to the north, the Andes Mountains to the west, the Brazilian central plateau to the south, and the Atlantic Ocean to the east.
Note: Tropical forests are closed-canopy forests growing within 28 degrees north or south of the equator. They are very wet places, receiving more than 200 cm of rainfall per year, either seasonally or throughout the year.
Temperatures are uniformly high – between 20°C and 35°C.
Such forests are found in Asia, Australia, Africa, South America, Central America, Mexico, and many of the Pacific Islands.
Significance of Amazon Rainforest
Amazon’s rainforest is home to 30% of the world’s species, comprising 40,000 plant species, 16,000 tree species, 1,300 birds, and more than 430 species of mammals.
The rainforest is also a carbon sink — a place that absorbs more carbon dioxide than it releases. It plays an essential role in combating climate change.
What is happening with the Amazon Rainforest?
The Amazon Rainforest is getting impacted by activities such as Deforestation, increase in temperature and other human-induced activities. Due to this, it is losing its ability to bounce back from damage caused by droughts, fires, and deforestation.
The study has also warned that the rainforest may become a dry savanna-like ecosystem. This means that it could transform into a carbon source: Places that release more CO2 than they absorb.
