This paper reports the relocation of Buchanania barberi from its type locality after a lapse of 119 years from its first collection.

This research work assessed the regeneration status of tree species across three altitudinal ranges (800–1600 m, 1600–2400 m, and 2400–3200 m) in the Anni Forest Division of Kullu district, Himachal Pradesh, by evaluating densities of seedlings, saplings, and adult trees. In zone-I, Melia azedarach emerged as best performer with 300 individuals/ha particularly at Shamesha site. In zone-II, Cedrus deodara recorded highest total regeneration with 290 individuals/ha particularly at Gugra site. In zone-III, Quercus semecarpifolia recorded highest total regeneration with 230 individuals/ha particularly at Lajheri site. It was found that the overall regeneration trend was positive as most of the species showed healthy levels of seedling and sapling density across all zones. Weak regeneration of some dominant species alongside expansion of less dominant or rare species indicates potential future shifts in forest composition.

The cold desert biome of Spiti Valley, located in the north-western Trans-Himalayas of Himachal Pradesh, is a biodiversity-rich region supporting a wide range of medicinal and aromatic plants (MAPs) within its unique ecosystems. These temperate and alpine species serve as important raw materials for traditional herbal medicines used in the Amchi healthcare system practiced in Spiti Valley. This indigenous system, derived from Tibetan medicine and linked to the broader Chinese medical tradition, represents a valuable cultural heritage. Experienced Amchis prepare herbal remedies using traditional formulations by combining various plant species to treat local tribal communities. However, the survival of these medicinal plants and the continuity of the Amchi tradition are increasingly threatened by rapid developmental activities in the fragile Trans-Himalayan region. Depletion of plant resources from easily accessible areas has further weakened the profession and created serious concerns for the future of this traditional knowledge system. The present manuscript highlights plant species at risk from development pressures and notes the changing social trend of abandoning traditional medicine. Sustainable resource management, environmental awareness, and participatory assessment before development projects are essential to conserve both medicinal flora and this cultural heritage.

Present study endeavours to propagate Oroxylum indicum using vegetative propagation techniques. Stem cuttings and root cuttings are used as propagules. The cuttings were subjected to optimal environmental condition, well-draining rooting medium and treated with variable concentration of rooting hormones (IBA and NAA) for better root development. Data was documented on root development and overall growth. Vegetative propagation techniques yielded promising results, with plantlets developed from root cuttings displaying superior survival rates (55%) and rooting response compared to those from stem cuttings. These findings offer valuable insights for optimum propagation of O. indicum. Therefore, it is recommended that root cuttings be used as the preferred propagule for large-scale propagation and conservation efforts aimed at preserving this vital species.

The Sherdukpen tribe, a major ethnic group of West Kameng district in Arunachal Pradesh, possesses rich ethnobotanical knowledge and relies extensively on plant resources. This study aimed to document and evaluate culturally important tree species used by the community. Data were collected from 105 informants across seven villages through questionnaires and personal interviews. A total of 30 tree species, representing 23 genera and 18 families, were recorded and classified into eleven use categories, with Rosaceae as the dominant family. Food category accounted for the highest proportion (25%), while manure category was minimal (2.9%). Gender-based knowledge variation was observed, with women more familiar with food-related species and men with species used for construction, tools, and poison. Pinus wallichiana, Quercus griffithii, and Rhododendron arboreum showed the highest cultural importance. The study highlights diverse utilization patterns and cultural significance of tree resources.
