ArticleTraditional knowledge and uses of medicinal plants in Jharkhand state of India
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Jharkhand, an eastern state of India , is abound in medicinal plants and rich in related indigenous and traditional knowledge. The tribals like Santhal, Ho, Birhor, Oraon, Munda, and Bhumij use powder, oil, paste, juice and decoction of these plants to cure various diseases. Since time immemorial, forest has been the main source of medicinal plants. But due to extensive use of these plants and deforestation, some of the medicinal plants are on the verge of extinction. Similarly traditional knowledge (TK) related to conservation and sustainable use of these plants are also threatened due to acculturation in the society. The present paper depicts TK related to conservation and uses of medicinal plants in Jharkhand state of India. The study was conducted in Dhanbad, Bokaro, Gumla, East Singhbhum (Jamshedpur) ,West Singhbhum (Chaibasa) and Hazaribagh districts of Jharkhand. The survey was done in two steps-Reconnaissance survey and Survey for actual research work with questionnaires. During study fifty plants were recorded eg. Abrus precatorius L., Acorus calamus L., Adhatoda zeylanica Medic. , Allemanda cathartica L., Asparagus racemosus Willd., Bacopa monniera (L.) , Clitoria ternatea L, Hemidesmus indicus R.Br ,Vitex negundo L., Ocimum sanctum L., Rauvolfia serpentina (L.)Benth.exKurtz, Terminalia tomentosa (DC) Wt. & Arn, Terminalia Arjuna (Roxb. exDC.) Wt. & Arn., Trachyspermum ammi (L.)Spr. etc. The study reveals that these people possess comprehensive TK for treatment of various ailments like cough, cold, fever, jaundice, skin diseases, wounds etc. using these plants. Due to their utility local people could conserve these plants for a long period of time as sacred groves, by adopting sustainable methods, following taboo and respecting traditional spirits. Conservation of such traditional wisdom and biodiversity is required; hence besides other measures, documentation of this knowledge as educational material is also recommended.

ArticleTree diversity, stand structure and community composition of tropical forests in Dalma Wildlife Sanctuary of Jharkhand, India
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Species diversity and density of trees were assessed in forests of Dalma Wildlife Sanctuary of Jharkhand comprising mostly of tropical deciduous forests. We compared tree community characteristics like stem density, basal area, diversity index, Beta(β diversity), Girth class, Canopy height class and species composition of tree species in all three zones ( Altitude between 199 -603m) in the study area. A total of 41 tree species of 25 families, 71 genera, and 95 species were recorded. Gramineae (10) family is most represented followed by Euphorbiaceae(6). It was noticed that the tree density varied from 30.64 to 62.51. The maximum basal area contributed by Terminalia belerica(1.323 m2ha-1) followed by Albezzia stipulate(1.145 m2ha-1). Shannon Weiner index (H’) ranged from 3.073 to 3.997 and species richness index ranged from 1.05 to 1.20. Beta diversity of tree species varied from 2.32 to 3.80. The highest number of tree species was occurred in girth class of 61 – 80 cm in all three zones. At present the biodiversity of these forests are under threat due to the anthropogenic and illegal interference of outside people for cutting of furniture tree species. The present study will help us to understand the patterns of tree species composition and diversity in the Dalma Wildlife Sanctuary, of India.

DocumentManaging taxonomic and functional diversity is the key to sustain aboveground biomass and soil microbial diversity: A synthesis from long-term forest restoration of southern China
XV World Forestry Congress, 2-6 May 2022

No results found.Exploring the biodiversity-ecosystem functioning relationship is one of the central goals of ecological research. Restoration is essential for supporting key ecosystem functions such as aboveground biomass production and managing soil microbial diversity. However, the relative importance of functional versus taxonomic diversity in explaining aboveground biomass and soil microbial diversity during restoration is poorly understood. Here, we used a trait-based approach to test for the importance of multiple plant diversity attributes in regulating aboveground biomass and soil microbial diversity in four 30- years-old restored subtropical forests in southern China. High-throughput Illumina sequencing was applied for detecting fungal and bacterial diversity. We show that both taxonomic and functional diversities are significant and positive regulators of aboveground biomass; however, functional diversity (FD) was more important than taxonomic diversity (TD) in controlling aboveground biomass. FD had the strongest direct effect on aboveground biomass compared with TD, soil properties, and community weighted mean (CWM) traits. Our results further indicate that leaf and root morphological traits and traits related to the nutrient content in plant tissues showed acquisitive resource use strategy which influenced aboveground biomass. In contrast to aboveground biomass, taxonomic diversity explained more of the soil microbial diversity than the FD and soil properties. Prediction of fungal richness was better than that of bacterial richness. In addition, root traits explained more variation of soil microbes than the leaf traits. Our results suggest that both TD and FD play a role in shaping aboveground biomass and soil microbial diversity; but FD is more important in supporting aboveground biomass while TD for belowground microbial diversity. These results imply that enhancing TD and FD is important to restoring and managing degraded forest landscapes.
