Subject: Endemic orchids of India : A Checklist
Keywords: Conservation prioritization, Orchid restoration, Phenology.
Abstract: India harbours exceptional orchid endemism. Authors compiled and analysed a curated dataset of about 276 endemic orchid taxa from India. Epiphytes dominates rediversity(59.8%), followed by terrestrial orchids (35.1%) and myco-heterotrophs (4.7%). Species richness is concentrated in the Northeast and Western Ghats, with Kerala, Northwest India, Andaman and Nicobar Islands, Tamil Nadu and Karnataka leading the state-level counts. The authors highlighted these patterns within a conservation framework that priorities in gold-growth canopy and host-tree networks in humid forests, microhabitat refugia across elevational gradients, ex situ backup for micro range, myco-heterotrophic taxa and community-led stewardship in human dominated landscapes. The present study provides a reproducible baseline, visuals, and state-level targets to inform policy and restoration.

Keywords: Healthcare benefits, Economic development, Cultural heritage, Environmental sustainability, Medicinal plant cultivation, Agriculture diversification.
Abstract: Medicinal plants are vital for a village, society, state or country, providing significant healthcare benefits, driving economic development, and supporting cultural heritage and environmental sustainability. They form a crucial natural resource with local and global impact. The cultivation, collection, processing, and trade of medicinal plants create significant employment opportunities, particularly in rural hilly areas. Promoting the cultivation of medicinal plants encourages agricultural diversification and offers farmers profitable alternative crops, which can enhance economic stability. For the achievement of required goals in medicinal plant sector Uttarakhand has formulated important policies and infrastructure development in the state, which resulted positive present outcomes and bright future prospects.

Subject: Indigenous Wisdom to Ethical Innovation in Tribal Knowledge Protection, Medicinal Plant Quality Integrity, and Nagoya-Compliant Conservation Priorities
Keywords: Indigenous knowledge systems, Medicinal plant quality integrity, Nagoya Protocol compliance, Biocultural conservation, Ethical bioprospecting.
Abstract: Traditional medicinal knowledge (TMK) developed by indigenous and tribal communities embodies one of humanity's oldest and most ecologically grounded healthcare systems. This knowledge—rooted in ancestral wisdom, biodiversity stewardship, spiritual frameworks, and centuries of practical experimentation—continues to inform modern Ethnopharmacology and drug discovery. However, accelerating Bio-piracy, unsustainable bioprospecting, habitat destruction, climate instability, and weakening intergenerational knowledge transmission now threaten both TMK and the biodiversity on which it depends.Aligned with the CBD COP-16/4 (2024) decision on Article 8(j), this article presents a novel, three-pillar framework to protect traditional knowledge systems, ensure medicinal plant quality integrity, and implement Nagoya-compliant conservation strategies. It proposes a forward-looking roadmap integrating indigenous stewardship, modern scientific validation, ethical governance, and community-led conservation and propagation models. The approach not only preserves cultural identity but also strengthens national biodiversity strategies, sustainable livelihoods, and future drug discovery pipelines.

Abstract: A high degree of accuracy, which to the practical forester must in the majority of cases be merely of academic interest, is a sine qua non for all sample plot measurements. Most delicate and elaborate methods with varying claims to accuracy have been therefore advanced from time to time to eliminate the errors involved in sample plot measurements. In these provinces, however, we follow the Dehra Method which claims to achieve a high degree of accuracy by means of a simple device which consists in replacing the less elaborate through by no means less accurate Volume Curve by form factor and height curves.

Plants have become the basis of classy systems of traditional medicine that have existed for thousands of years and continue to provide humanity with new medicines. Early humans gained knowledge of the use of plants for therapeutic purposes and trials through many years of careful observations, experimentation, and errors (Reddy et al,2003; Karunamoorthi et al., 2013).Nature has endowed our country with an immense wealth of plants (Shakya,2016). India is a country rich in a diversity of plants with three levels of biodiversity, that is species diversity, genetic diversity, and habitat diversity.

Subject: Growth and Instability in Pine Rosin Production, Export and Import In India
Keywords: Pine rosin production, Import dependence, Trade instability, Non-timber forest product (NTFP), Sustainable forest management.
Abstract: This study examines the growth and instability in India's production, export, and import of pine rosin from 2003–04 to 2023–24. Analysis reveals a severe decline in domestic resin production, particularly in Himachal Pradesh and Uttarakhand, with an overall annual growth rate of –7.326% between 2007–08 and 2019–20. This drop is attributed to ecological stressors, unsustainable tapping practices, socio-economic shifts, and policy constraints. As a result, India's export volumes collapsed by over 86%, becoming highly unstable and marginal, while unit export values rose significantly. Conversely, imports grew steadily at 3.124% per annum, reaching 42,542 tonnes in 2023–24, with over 75% sourced from Indonesia, highlighting heavy import dependence. Instability indices confirm volatile exports but stable imports, underscoring supply-side vulnerabilities. The paper concludes with a forward-looking estimate suggesting that tapping just 5% of India's Pinus roxburghii trees could meet domestic demand, save approximately $47.82 million in imports, and generate significant rural employment. Urgent policy interventions are recommended to revitalize sustainable domestic production and reduce external reliance.

Abstract: Magnolia gustavii King, a Critically Endangered tree species has been rediscovered from Dangori Reserve Forest in Assam (India) after a lapse of 133 years; since the last herbaria of M. gustavii were collected during 1890-1891 and thereafter no information on existence of this species in Assam has been reported till date. In addition, population structure and regeneration status of this species was studied and threats to this species were identified to develop effective conservation implications. A total of 31 individuals from a single population occurring in Dangori Reserve Forest under Doomdooma Forest Division, Tinsukia district, Assam were identified as M. gustavii with maximum (17) individuals in the Diameter at Breast Height (DBH) class 56-65 cm and least (1) in DBH class 36-45 cm. Regeneration status was observed to be 'None' as only mature trees were occurring in study sites. The existing population of this species is under threat owing to anthropogenic activities, meteorological factors, grazing/foraging, lack of natural regeneration, Land Use Land Cover (LULC) change etc. As a protective measures against the threats, recovery programme of the species at Species level was taken up by reintroducing saplings in wild (in-situ conservation) as well as in newer potential habitats (ex-situ conservation) to sustain the current population from extinction.

Various traits like plant height, leaf dimensions and shape, length of inflorescence, and size of fruits have been considered for comparison and analyzed using ANOVA. Except for fruit traits, all other characters exhibited considerable morphological variations. Further, these variable traits posed ambiguity in the taxonomic identity of the taxon at first glance.
