Arunachal Pradesh is drawing renewed scientific interest after a series of rediscoveries and new species records from its forests, streams and mountain regions. The state, located in the Eastern Himalayas, has varied habitats ranging from tropical foothill forests to high-altitude zones. According to the MyGov Blog, more than 80 percent of the state is under forest cover, making it a major area for biological research in India.
Researchers have reported rare plants that had not appeared in scientific records for long periods, along with new orchids, frogs, butterflies, fungi and other species. These findings are significant because many parts of Arunachal Pradesh remain underexplored by scientists, especially remote valleys and forested areas that are difficult to access.
Rare blueberry relative found after 188 years
One of the key recent findings is the rediscovery of Vaccinium piliferum, a rare wild relative of the blueberry. The plant was first collected in 1836 by British botanist William Griffith from the Mishmi Hills. It was later documented in the Khasi Hills in 1850.
After that, the species remained absent from scientific records for nearly 188 years. In 2024, researchers found it again in the forests of Vijoynagar in Changlang district. The rediscovery highlighted how little is still known about some forest areas in the state and how older records can guide modern botanical surveys.
New orchid and flowering plant records
Arunachal Pradesh is already known for its orchid diversity. The source notes that the state has more than 650 species of orchids. Recent discoveries have added to that list.
Hemipilia basifoliata, a new orchid species, was identified in the Myodia region of Lower Dibang Valley district. Another orchid, Gastrodia lohitensis, was discovered in Lohit district. This plant is unusual because it is leafless and does not depend on photosynthesis. Instead, it gets nutrients through a relationship with fungi.
Scientists have also documented new species from plant groups such as Begonia and Impatiens in different parts of the state. Impatiens rajibiana, a new balsam species, was found at Shergaon in West Kameng district. Another important rediscovery was Geum macrosepalum, a rare Himalayan flowering plant recorded near Sela Pass after more than a century since its last documented sighting in India.
Frogs, butterflies and other wildlife findings
Wildlife surveys have also produced notable records. Scientists from the Zoological Survey of India discovered three new cascade frog species from mountain streams in Arunachal Pradesh. They were named Amolops tawang, Amolops chanakya and Amolops terraorchis. The discoveries came from Tawang, Dirang and the Sessa Orchid Sanctuary.
In 2026, researchers reported a new butterfly species from the Basar region of Leparada district. The species, Euthalia zubeengargi, was named in honour of singer Zubeen Garg. In Upper Siang district, biodiversity surveys recorded six butterfly species that had not previously been documented in India.
The source also mentions continuing records of new bush frogs, reptiles, insects, butterflies and freshwater fishes from different parts of Arunachal Pradesh. These findings show that field surveys are still adding basic scientific information about the state’s wildlife.
Fungi and forest health
The state’s forests have also produced important records in mycology, the study of fungi. Researchers have documented rare and previously unrecorded mushroom and fungal species, including distinctive puffball mushrooms from Longding district.
Fungi are a less visible part of biodiversity than birds, mammals or flowering plants, but they are closely linked to forest processes. Records of fungi help scientists understand forest ecology more clearly, including nutrient cycles and relationships between plants and soil organisms.
Local communities and field knowledge
The MyGov Blog notes the role of indigenous communities in conserving biodiversity across Arunachal Pradesh. Local communities have long-standing knowledge of forests, plants, animals and medicinal resources. Their familiarity with terrain and habitats can help researchers locate rare species and reach areas that may otherwise remain poorly studied.
Traditional conservation practices and community stewardship have helped maintain stretches of forest and natural habitat in the state. Scientific surveys often depend on this local knowledge, especially in remote regions where formal records are limited.
Why these records matter
Rediscoveries are important because they confirm that species once considered extremely rare, or absent from records for decades, may still survive in suitable habitats. New species descriptions also help scientists build a more accurate picture of biodiversity in the Eastern Himalayas.
For Arunachal Pradesh, the recent findings point to the need for continued research and careful conservation of forests, rivers, wetlands and high-altitude ecosystems. Many species mentioned in the recent records were found in specific localities, which makes their habitats important for future monitoring.
Large parts of the state remain biologically underexplored. The rediscovery of Vaccinium piliferum, the records of rare flowering plants, and the discovery of new frogs and butterflies suggest that further surveys may continue to add to India’s biodiversity knowledge.
