70 orchid species recorded in Kaziranga Tiger Reserve
Officials of the UNESCO World Heritage Site said on Thursday (May 15, 2025) these species across 36 genera were documented during a rapid survey conducted in the 1,302 sq. km protected area. Of these 79 species, 46 are epiphytes and 24 are terrestrial.
An epiphyte is a non-parasitic plant that grows on another plant.
Sonali Ghosh, the director of the tiger reserve, said the survey was an outcome of recent efforts for systematic documentation of Kaziranga's floral and faunal assemblages. 'The survey yielded new records, especially for grasslands and woodlands,' she said.
The bulk of these orchids (39 species) was recorded from the Panbari Reserve Forest within the tiger reserve.
Terrestrial orchids, such as Eulophia dabia, Zeuxine lindleyana, and Nervilia Juliana, were found along the riverbanks in the grasslands, while others like Acanthephippium striatum and Hetaeria affinis were recorded from the dense forest floor.
Among the species endemic to India are Biermannia bimaculata, Eulophia kamarupa, and Zeuxine lindleyana. The Bulbophyllum ornatissimum, Erythrodes blumei, Eulophia kamarupa, and Zeuxine membranacea are considered rare in Assam.
The survey was led by Khyanjeet Gogoi, an orchid conservationist and two Kaziranga range officers – Bibit Dihingia of the Bagori Range and Bibhuti Ranjan Gogoi of Kohora Range.
Ms Ghosh said the orchid survey was preceded by a unique conservation outreach programme focused on familiarising local students with the orchid and butterfly diversity in the Kaziranga landscape.
During the event with the students, three brochures highlighting the birds of Panbari and the butterflies and orchids of Kaziranga were released to raise awareness and appreciation of the region's rich biodiversity.
Assam's Environment, Forest, and Climate Change Minister, Chandra Mohan Patowary, said the orchid discovery has added a new layer to Kaziranga's iconic wildlife.
Kaziranga has an estimated 2,613 greater one-horned rhinoceroses, 104 tigers, 1,228 Asian elephants, 2,565 wild water buffaloes, and 1,129 eastern swamp deer. The censuses for these 'Big Five' animals were conducted between 2022 and 2024.

How does river Ganga look from space? NASA releases stunning picture from ISS that will leave you dazzled
The Ganges – Brahmaputra Delta, also called the Bengal Delta or Sundarbans Delta, spreads over more than 100,000 square kilometres and flows into the Bay of Bengal. This area is home to millions of people, providing rich farmland and supporting a variety of plants and animals. It also contains the famous Sundarbans mangrove forest, a UNESCO World Heritage Site, and is known for its winding rivers, tidal changes, and seasonal floods. Don Pettit used near-infrared photography to capture the Ganges River delta in a way that makes its green landscapes and winding rivers stand out with striking detail. Sharing the image online, Pettit wrote, 'Ganges river delta, over India and Bangladesh, photographed in near-infrared from the ISS. It is the largest river delta on Earth.' The technique not only creates a visually stunning picture but also helps scientists track plant health, water flow, and changes in the land—crucial for studying one of Asia's most important ecosystems.

First-ever grassland bird census : A must-know for UPSC exam
Take a look at the essential concepts, terms, quotes, or phenomena every day and brush up your knowledge. Here's your knowledge nugget on the grassland bird census at the Kaziranga National Park. (Relevance: The IUCN status of species has been asked in the UPSC examination multiple times. This grassland bird census encompasses important species relevant from an exam perspective. Also, the recent report on the status of Tigers in the Kaziranga National Park is important for Prelims and Mains.) Between March 18 and May 25, a survey to record the grassland bird population in Kaziranga National Park was undertaken by a team of forest officials, scientists, and conservationists. It is the 'first-ever grassland bird census' conducted in Assam's Kaziranga National Park. This census was also mentioned in the Mann ki Baat radio programme by Prime Minister Narendra Modi on Sunday (July 27). 1. The grassland bird census recorded a total of 43 grassland bird species, including 1 Critically Endangered, 2 Endangered, and 6 Vulnerable species, according to the International Union for Conservation of Nature (IUCN) Red List. 2. A new methodology was deployed in the survey, which was also mentioned in the Maan ki baat program. According to Kaziranga National Park Director Dr. Sonali Ghosh, the use of passive acoustic recording monitoring was the highlight of the survey. 3. 'Surveying these small, shy, and highly camouflaged birds is very difficult using traditional methods like visual counting. So, the acoustic recorders were placed in tall trees near grasslands during the breeding season of the birds, between March and May. This is the season when they are very vocal, calling out for mates and with males defending territory. The instruments recorded all the birds singing in the landscape,' she said. 4. Different tools were then used to identify the birds based on the recordings. For the bird sounds that were not identifiable, a spectrogram (a graphical representation of the sound) was created using software to aid in identification. The Birdnet tool was also used, which applies Machine Learning to try and identify species by bird song. 5. The survey prioritised 10 species that are either globally threatened or endemic to the Brahmaputra floodplains: 6. The national park authorities have been particularly excited by the discovery of a breeding colony of the endangered Finn's Weaver, which is endemic to the Brahmaputra flood plain. 7. Dr. Ghosh called grassland birds 'an indicator of good health' of an ecosystem, likening them to indicators such as BMI for human health. 'The presence of these birds tells us that the habitat is healthy,' she said. 1. Grasslands — home to the great Poaceae family, with its 10,000 to 12,000 members or species — cover vast swathes of landmass throughout the world and support a wide variety of animal life. They thrive in places where the rainfall is low, typically between 600 and 1500 mm annually. 2. They are even more useful than forests and provide a host of ecosystem services — storing water and carbon, recycling chemical, and controlling the climate. And, vitally, feeding us and our livestock, besides the wild herbivores that roam the plains. Even the ferocious carnivores must be grateful to grasslands: because grasses feed their prey species. 3. In India, almost a quarter of landmass is covered in grassland. This includes the alpine meadows of the Himalayas, the chaurs in the foothills, the famous terai grasslands in the flood plains of the Ganges and Brahmaputra, the phumdis, or the quivering wet grasslands of Manipur (where the deer 'dance'), the savannas of western and peninsular India and the renowned 'sholas' of the Western Ghats. 4. Different names are used in the world to refer to grasslands. According to WWF, it is known as 'savannah' in Africa, 'cerrado' in South America, 'prairie' in North America, 'steppe' in central Asia, and 'meadow' in the UK. 5. What makes them special is their ability to survive and keep growing no matter how much they're munched or nibbled by animals. It supports all kinds of wildlife. The one-horned Indian rhinoceros and wild water buffalo live in the wet grasslands of Kaziranga and Manas Tiger Reserve. The swamp deer live in the terai. Manipur's rare 'dancing deer' or 'Sangai' thrive on the floating phumdis of Loktak Lake. 6. Grasslands (except a few) — like the wetlands — in India get no protection. They are free to be exploited. According to the report on the degradation of rangelands, published last year, by the UN Convention on Combating Desertification (UNCCD), less than 5 per cent of India's grasslands fall within protected areas, and the total grassland area declined from 18 to 12 million hectares between 2005 and 2015. 1. On Tuesday (29th July), officials released a summary report for 2024 titled 'Status of Tigers in the Kaziranga Tiger Reserve', with the findings of a Phase IV tiger monitoring initiative across Eastern Assam, Nagaon, and Biswanath Wildlife Divisions. This was done at the direction of the National Tiger Conservation Authority (NTCA). 2. The survey documented 148 tigers in the reserve, up from 104 recorded in 2022, 99 in 2018 and 96 in 2014. Reserve director Sonali Ghosh said these findings show that Kaziranga has the third-highest density of tigers in the world, after Corbett Tiger Reserve in Uttarakhand and Bandipur Tiger Reserve in Karnataka. 3. The survey was conducted over 103 days using 293 paired camera traps across 1307.49 square kilometres, which yielded 4,011 tiger images in 242 locations. The report states that the right-flank stripes of the animals in these images were used to identify 148 adult tigers – 83 females, 55 males, and 10 with undetermined gender. 4. 'Despite these successes, Kaziranga's tiger population faces persistent challenges, including habitat fragmentation, human-wildlife conflict, and the pressures of agricultural expansion and infrastructure development around the tiger reserve', it states. Covering 42,996 ha, Kaziranga National Park is located in the State of Assam. It is the single largest undisturbed and representative area in the Brahmaputra Valley floodplain. It is a UNESCO World Heritage Site recognised in 1985. It is renowned for its significant population of one-horned rhinoceroses. The NTCA is a statutory body under the Ministry of Environment, Forests and Climate Change constituted under the enabling provisions of the Wildlife (Protection) Act, 1972, for strengthening tiger conservation, as per powers and functions assigned to it under the said Act. The NTCA conducts the All India Tiger Estimation to track the big cat numbers, usually in cycles of four years. Yes. Established in 2023, honouring 50 years of Project Tiger, the IBCA aims to promote the protection of seven big cats: the tiger, leopard, snow leopard, lion, cheetah, puma and jaguar.

Kaziranga records high diversity of grassland bird species
GUWAHATI Researchers have found a great diversity of grassland bird species in the Kaziranga National Park and Tiger Reserve. In the first such survey of avians conducted between March 18 and May 25, a team of forest officials, bird experts, scientists, and conservationists recorded 43 grassland species across Kaziranga's three wildlife divisions. The survey report was released on Monday (July 14, 2025), marking a milestone in the documentation and protection of grassland-dependent bird species in the Brahmaputra floodplains. They included the critically endangered Bengal florican, the endangered Finn's weaver, and the swamp grass babbler. Among the remaining 40 species, six were in the vulnerable category — the black-breasted parrotbill, marsh babbler, swamp francolin, Jerdon's babbler, slender-billed babbler, and bristled grassbird. Grassland health 'A highlight of this survey is that the Finn's weaver, locally known as tukura chorai, is breeding successfully. This remarkable bird, a master nest-builder atop trees, is a vital indicator of grassland health,' Assam's Environment Minister, Chandra Mohan Patowary, said while releasing the report. The 1,174 sq. km Kaziranga is a mix of grasslands, forestlands, and wetlands. 'The study is significant because wet grasslands are not very well surveyed in India. Kaziranga's grassland bird diversity can, thus, be compared in terms of species richness with the dry grasslands of Gujarat and Rajasthan,' the national park's director, Sonali Ghosh, said. A key highlight of the study was the deployment of passive acoustic recorders, enabling non-invasive and continuous monitoring even in inaccessible or high-risk areas. This approach significantly improved species detection, especially of shy and cryptic birds, enhancing the overall accuracy and depth of the findings. The report identifies several critical grassland habitats within Kaziranga that support significant populations of threatened and endemic species. One such habitat is the park's Kohora Range, where a breeding colony of the Finn's weaver was spotted.
