70 orchid species documented in Assam's Kaziranga National Park
KNPTR Director Sonali Ghosh said that in the recent efforts for systematic documentation of Kaziranga's rich floristic and faunal assemblages, a rapid survey on orchids has revealed interesting results, with the visual survey reporting new records, especially for grassland and woodland areas.
She said that 70 orchid species across 36 genera within Kaziranga, of which 46 species are epiphytes and 24 are terrestrial, have been recorded in the study.
According to the official orchids like Acanthophippiumsylhetense, Aerides odorata, Biermanniabimaculata, Bulbophyllumornatissimum, Cleisostomaappendiculatum, Dendrobium jenkinsii, Eulophiakamarupa, Peristylusconstrictus, Phalaenopsis mannii, Zeuxinemembranacea etc. have been recorded in the survey.
Led by Khyanjeet Gogoi, a renowned orchid conservationist and Range officers of Bagori, Bibit Dihingia and Kohora Bibhuti Ranjan Gogoi, the visual survey reported new records, especially for grassland and woodland areas, Ghosh said.
She said that terrestrial orchids such as Eulophiadabia, Zeuxinelindleyana, and Nervilia Juliana thrive in the grasslands along the river banks, while others like Acanthephippium striatum and Hetaeriaaffinis flourish on the dense forest floor.
Notably, species like Biermanniabimaculata, Eulophiakamarupa, and Zeuxinelindleyana are endemic to India, while Bulbophyllumornatissimum and Erythrodesblumei, Eulophiakamarupa and Zeuxinemembranacea are considered rare in Assam.
KNPTR Director said that the orchid survey was preceded by a unique conservation outreach program that focused on familiarising local students with the orchid and butterfly diversity in the landscape.
The Orchid and Butterfly Walk, held on April 18 and 19 in Panbari, welcomed over 50 enthusiastic students from various schools and colleges in the region.
During this event, three brochures highlighting the birds of Panbari, butterflies of Kaziranga and Orchids of Kaziranga were released. These informative brochures aim to enhance awareness and appreciation of the rich biodiversity found in this region, the official said.
Participants enjoyed guided safaris in Panbari, immersing themselves in the natural beauty of the park while observing orchids and butterflies along the vibrant flora and fauna.
Expert talks on orchids and butterflies were delivered by renowned speakers Khyanjeet Gogoi and Monsoon Jyoti Gogoi, who shared their extensive knowledge and passion.
Assam's Environment, Forest and Climate Change Minister Chandra Mohan Patowary in a social media post said: 'Kaziranga National Park & Tiger Reserve just got even more amazing! A recent survey has revealed 70 species of orchids across 36 genera, making it one of the richest orchid collections in northeast India.'
'This vibrant floral discovery adds a new layer to Kaziranga's already iconic wildlife. A true testament to the park's thriving biodiversity and unwavering conservation efforts!' the minister said.
The KNPTR comprises three forest divisions -- the Eastern Assam Wildlife Division, Bokakhat; the Bishwanath Wildlife Division, Biswanath Chariali; and the Nagaon Wildlife Division, Nagaon.
Home to a remarkable population of the "Big Five," it comprises 2,613 Greater One-horned Rhinoceroses as of the 2022 census, 104 Bengal Tigers in 2022, 1,228 Asian Elephants in 2024, 2,565 Wild Water Buffalos in 2022, and 1,129 Eastern Swamp Deer also recorded in 2022.

India's Forests Are Greener—but Storing Less Carbon: New Study Reveals a Sequestration Crisis
Published : Aug 04, 2025 17:30 IST - 5 MINS READ Through photosynthesis, trees and plants absorb carbon dioxide and turn it into energy needed for growing trunks and roots. This process of removing carbon dioxide from the atmosphere and storing it as biomass is called carbon sequestration. It is this ability of trees and plants that can help mitigate the impacts of climate change. The Indian government, much like many other governments and private companies around the world, is banking on forests and plantations to tackle climate change. As part of climate commitments under the Paris Agreement, the Indian government has pledged to create an additional carbon sink of 2.5 to 3 billion tonnes of CO2 (carbon dioxide) through additional forest and tree cover by 2030. There are ongoing efforts by the Ministry of Environment, Forest and Climate Change, such as the National Afforestation Programme (NAP) and the Green India Mission (GIM), aimed at afforestation and plantation activities. GIM is one of eight 'National Missions' under the National Action Plan on Climate Change. Also Read | 'Maladaptation' fears might end up blocking climate funds for poor nations Over the past few years, India has experienced significant greening, driven by irrigated agriculture and plantations. But to be an effective climate mitigation tool, the greening should translate to effective carbon sequestration. A new scientific study says this is not happening. Published in the journal Resources, Conservation & Recycling last month by two scientists from IIT-Kharagpur, the study shows that in the last decade (2010-2019), carbon stock capacity declined by 5 per cent compared to the decade before (2000-2009). In some regions like the eastern Himalaya and the Western Ghats, the decline in forest carbon stock is as high as 17-20 per cent. 'Green-ness is on the outside. It is structural. And carbon uptake is a functional quality,' said Rahul Kashyap, the lead author of the study and Prime Minister's Research Fellow (PMRF) at CORAL, IIT Kharagpur. 'For Indian forests, the outer green-ness is increasing, but functional health, of which a key aspect is the ability to act as carbon sinks, is declining,' he added. The study notes how greening is translating to biomass production at lower rates than before. And the reason is reduced soil moisture due to climate change-driven warming and activities like deforestation and plantations. And this trend is set to continue till 2100. Jayanarayanan Kuttippurath, the other author of the study and an Assistant Professor at IIT Kharagpur, said, 'The atmosphere is continuously warming. The mitigation action the world is taking [to reduce the usage of fossil fuels] is not enough. And we are continuously emitting carbon dioxide and other greenhouse gases. On top of this, we have forest fires and deforestation. This is why the translation from green-ness to biomass is also decreasing.' Plants under stress Temperatures are rising and soil moisture is decreasing, causing heat stress in plants, which are unable to produce biomass and sequester carbon dioxide at rates they used to earlier. 'There are forest-dwellers and their livelihood. We have a big forest economy, and this will also be compromised. In addition to this, we have a net-zero target by 2070. The declining carbon stock capacity is a big concern,' Kuttippurath said. The study is first-of-its-kind to estimate Ecosystem Photosynthetic Efficiency (EPE), which is a measure of translation of greenness to carbon uptake, across Indian forests. It finds that the largest declines in EPE are in the Eastern Himalaya, the Western Ghats, and the Indo-Gangetic Plain, which, interestingly, have the highest EPE in the country. 'We are losing quality forests' Over the last two decades, reports by the Forest Survey of India have shown how green cover and forest cover in India are increasing. But this includes lots of areas outside historical forests, such as plantations and agroforestry. 'Day by day, we are losing quality forests. We have different kinds of forests with different species and different kinds of disturbances like infrastructure development and invasive species. And climate change exacerbates the impacts of disturbances,' said Purabi Saikia, Associate Professor at the Department of Botany in Banaras Hindu University. As an ecologist, Saikia has conducted ground studies of forests across the country in States like Arunachal Pradesh, Madhya Pradesh, Jharkhand, and Tamil Nadu. 'Invasive species like lantana and parthenium are also part of the green cover, but they have low carbon sequestration compared to native trees,' Saikia explained. 'So, yes. We have increasing green cover but not in terms of forest productivity or ecosystem productivity,' she added. However, since the study is based purely on remote-sensing and predictions, Saikia called for more analysis based on ground-truthing. 'It is an important finding and the paper presents a good idea to carry forward with ground work in forests,' she added. Also Read | Are Giant Leatherback hatchlings from Galathea Bay being relocated? In the paper, too, the authors note that India needs more studies on forest carbon dynamics that integrate remote sensing observations and ground-based measurements. Declining forest sink capacity is a global issue, too. A study published last month showed that forest sink capacity in Europe, too, is 'rapidly declining'. And yet another study from July showed that tropical forests the world over are losing drought resilience. On the issue of declining forest carbon stock in India, the authors warn that it is 'imperative' not to misconstrue forest-based mitigation as a solution to climate change and that forest protection and afforestation measures should be done more scientifically to secure historical natural forests.

Law on anvil for blue economy, government tells Lok Sabha
The Centre is taking a systematic approach towards a legislative framework for implementation of the Blue Economy policy, the ministry of earth sciences informed the Lok Sabha on Wednesday. Law on anvil for blue economy, government tells Lok Sabha The draft national policy on blue economy, covering seven thematic areas including ocean governance and marine spatial planning, was placed in the public domain in February 2021 and revised in July 2022 after inter-ministerial and stakeholder consultations, the response said adding that the policy is aiming to harness ocean resources sustainably for economic growth while protecting marine ecosystems ensuring national security and it also provides the foundational basis for future legislation, the ministry said in response to a query, raised by MP Brijmohan Agrawal, on the major legislative steps taken by the government for Blue Economy. The deep ocean mission is a subset of the broader blue economy concept which is focused on technological development for exploring deep ocean resources, promoting climate change advisory services, conservation of deep-sea biodiversity, research on ocean biology, and harnessing energy and freshwater from the ocean. 'The current focus is on strengthening the existing environmental legal framework through targeted reforms, including amendments to existing laws and empowering the Ministry of Environment, Forest and Climate Change's umbrella legislation the Environment (Protection) Act, 1986. These reforms aim to introduce specific rules to address critical challenges such as e-waste (management), plastics waste management, batteries waste management, and end-of-life vehicles (ELVs) scrapping,' said Jitendra Singh, minister of state for earth sciences. He was responding to questions by BJP MP, Brijmohan Agrawal on the 1. major legislative steps taken by the Government for the Blue Economy district from policy-based approaches such as the Deep Ocean Mission along with the draft legislation; 2. inter-ministerial consultations or projected timelines for a Blue Economy Law; 3. existing mechanism which ensures sector-specific, legally binding environmental among others. The various sectors in the blue economy are governed by different laws which include: 1. Coastal and Marine Ecosystems governed by Environment (Protection) Act, 1986; Coastal Regulation Zone (CRZ) Notification, 2019 and Wildlife Protection Act, 1972, 2. Fisheries and Aquaculture governed by Marine Fishing Regulation Acts (State-specific); National Policy on Marine Fisheries, 2017; 3. Shipping and Ports & Security under the Merchant Shipping Act, 1958; Major Port Authorities Act, 2021; International Maritime Conventions (e.g., MARPOL) (via Merchant Shipping Act); Maritime Zones Act, 1976; Recycling of Ships Act, 2019 and Island Vessels Act, 2021, 3. Oil, Gas & Deep-Sea Mining under Oilfields (Regulation and Development) Act, 1948 and Offshore Areas Mineral (Development and Regulation) Act, 2002, 4. Tourism and Recreation under Environment (Protection) Act & CRZ Rules and Biological Diversity Act, 2002 and 5. Marine Biotechnology & Bioprospecting under Biological Diversity Act, 2002. The regulatory gaps and overlaps are being addressed through the PARIVESH portal of Ministry of Environment Forest and Climate Change which acts as a single window for environmental, forest, wildlife, and coastal regulation zone clearances and the National Sagarmala Apex Committee and PM Gatishakti portal also aid in integrated planning, Singh said. Further, there are dedicated laws and guidelines for investment, accountability, and liability including 100% FDI is permitted via the automatic route in sectors like sea-ports and aquaculture. Offshore mineral block auctions are open to foreign bidders with specified conditions. The Merchant Shipping Act, 1958, adopts international liability conventions and mandates compulsory insurance for pollution damage. Offshore safety is governed by the Oil Mines Regulations, 2017, and a draft Offshore Safety Directive. The 'Harit Sagar' Green Port Guidelines (2023) mandate ESG reporting for terminal operators. The Deep Ocean Mission requires Environmental and Social Due Diligence for its projects. Maritime Zones Act, 1976 along with updated rules like the Offshore Wind Energy Lease Rules, 2023, provides the legal framework for leasing and regulating offshore energy and mineral projects, the response said.
