The present study aims to document the traditional knowledge of medicinal plants of Kapurkot rural municipality of Salyan District, Karnali province, Nepal. Ethno medicinal information was collected through interview with 40 respondents from Mulpani, Sallyan District. Altogether 59 ethnomedicinal plant species are used for the remedies of different health ailments. Respondents of the age group 25-35 years were found actively participating in this survey. Zingiberaceae as well as the Lauraceae family were found to have the highest number of species used for ethno-medicinal purposes. On the basis of their habit, herb species are found to be highly dominated. The recorded 59 ethnomedicinal plants were used in the treatment of various diseases such as cuts and wounds, skin diseases, fever, cough, boils, burns, common cold, etc. From this study, mainly common cold and cough are mostly recovered ailments from medicinal plant species. The study is mainly based on the experienced knowledge and information which they gain from their elders, mainly from grandparents, which might pass from generation to generation. This current study reveals that Zanthoxylum armatum (Timur), Cinnamomum tamala (Tejpaat) and Zingiber officinale (Adhuwa) are respectively found to be highly traded medicinal plants of the study area. For the preservation of ethnomedicinal plants species as well as their traditional knowledge, different conservation activities should be practiced. Such gained information and knowledge should be passed from generation to generation and encourage them to preserve for sustainable use of traditional documentation.

Forest is one of the most important natural resources of the ecosystem which contributes in biodiversity conservation as well as plays a significant role in maintaining the earth’s climate by sequestrating atmospheric carbon. Tropical forests are rich in biodiversity and store large amounts of carbon. The studied Bolbum Community Forest (BCF) and Brahmakumari Global Religious Forest (BGRF) lie in tropical region between the altitudes 120 and 300 m asl in Rupandehi District of Nepal. The main objective of this research was to assess and compare tree diversities and carbon stocks in two different management regimes, namely, community forest and religious forest. Stratified random sampling technique was used for data collection. The allometric equation biomass-diameter regression (Model II) was used for estimation of carbon stock of tree species while Simpson and Shannon-Wiener indices were used to measure tree species diversity. The results showed that the carbon stock value was 27.15 t.ha-1 in BCF and 40.94 t.ha-1 in BGRF. The community forest had lower value of tree carbon stock than that of the religious forest. However, tree diversity was higher in BCF (25) than in BGRF (20). Shorea robusta was found to be the single dominant species in BGRF with higher basal area (102.24 m².ha-1) and contributed 56% of the carbon stock. The contribution of carbon stock of two co-dominant tree species in BCF were 32% for Shorea robusta and 26% for Terminalia anogeissiana. There was significant (p=0.05) positive relationship of carbon stock with basal area and DBH in both forest types.

The study aimed to document the indigenous knowledge and practices of using plant materials for medicinal purposes by the Danuwar community in Dudhauli municipality of Sindhuli district, central Nepal. Primary data were collected between October 2016 to January 2017 through key informant interviews and focus group discussion using a semi-structured questionnaire among local healers and various aged groups of people. The information was used to prepare descriptive analysis of plant species. Among 161 plant species belonging to 153 genera and 78 families used for the treatment of different ailments, most dominant family was Fabaceae followed by Lamiaceae and Asteraceae respectively. About two-fifth plants species were used in medicinal purpose for the treatment of 47 different ailments and herbaceous plant habit was widely selected followed by trees and shrubs. The highest number of plant species was used to treat digestive system ailments, followed by skin and integumentary ailments. Common modes of application were oral and poultice, in the form of juice and paste. Among documented plants, two species were reported for the first time having any ethnomedicinal uses and eight species with novel medicinal uses in Nepal. This study showed that Danuwar people still have better traditional knowledge among local healers and elderly people. They preferred conventional medical methods using plant remedies to treat various ailments. Medicinally important plants are under threat from habitat loss and deforestation and people know little about conservation. One third plant species were not protected by concerned people. However, modern medicine and urbanization have a minor impact on the health care system and lifestyles of Danuwars. Hence, it calls for the urgent initiation of conservation and sustainable harvesting of plants.

India is one of the foremost countries not only in Asia, but worldwide famed as far as the wealth of traditional knowledge and floristic richness is concerned. Within India, the state of Himachal Pradesh is rich in plant diversity and in addition is also gifted with rich and diverse heritage of cultural traditions. Arboreal plants form an integral source of readily available, traditional medicines to the indigenous communities of the far-flung remote regions. This study pertains to the important woody flora in the Nogli watershed area of Sutlej River Catchment, which are being utilized by the local communities. Ethnobotanical surveys carried between the years 2020 and 2022 are based on semi-structured questionnaires and group discussions, while reconnaissance survey was carried out in all seasons to understand and analyze the vegetation of the region. Response from 50 respondents covering all age groups was recorded. As an outcome, 44 plant species (26 trees and 18 shrubs) of ethno-medicinal importance were identified from the study area. The plant species are spread across 24 families with Rosaceae being the most dominant. The outcome from this study shall form the baseline data for ethnopharmacological research in future. In addition to this a conservation and management plan can also be chalked out for the species which are heavily extracted from the forests. Such systematic and researched information will add up to an extensive database of the plants used by native communities, and this information could be dispersed to the new generation for awareness and sustainable utilization of plants.

The genuine image of biodiversity, as well as their germplasm, is visualized by the turnover of species rather than their similarities in each location. The major goal of this study was to determine the b-diversity pattern of vascular plants growing at 100 m contour elevations and to explore its association with a-diversity and elevation. Primary data were gathered utilizing 4-6 10 x 10 m2 quadrats at 100 m contour elevation, on both the south and north sides, in Arghakhanchi district, west Nepal. Beta diversity represents the change in diversity of species between two communities and is measured by two different matrices: species turnover and similarity. Between two adjacent elevational bands, the species turnover was calculated using the Bray-Curtis dissimilarity index and similarity was assessed using the Jaccard index technique in the Vegan package for R version 4.03. The species richness (a-diversity) and b-diversity indices (Bray-Curtis dissimilarity index and Jaccard similarity index) were regressed by generalized linear model (GLM) method with elevation. The species richness and Jaccard similarity index suggests statistically significant unimodal structure with elevation; however, Bray-Curtis dissimilarity index suggests statistically significant but reverse unimodal pattern. As a result, rather than species turnover, the presence of more related species usually creates the peak area of a unimodal pattern of alpha diversity. The geographical scale of biodiversity loss or its effective preservation by human activities is revealed by beta-diversity. Any region with high beta diversity suggests a wide variety of species, which aids in the administration of conservation programs.

Understanding population structure and regeneration status reflects the biological and ecological characteristics of the forest. The present study aims to know the population structure and regeneration status of Pinus-Quercus mixed forest in Bhardeu village of Lalitpur district, central Nepal. The study was carried out by laying down twenty-eight concentric circular plots of 8.92-meter radius randomly during 2021-2022. Altogether 28 tree species belonging to 24 genera and 17 families are recorded. Five species (Miliusa velutina, Cinnamomum camphora, Eriobotrya dubia, Maesa chisia and Saurauia napaulensis) were only recorded in adult form. The forest was found to be dominated by the species of Pinus and Quercus with the important value index (IVI) values ranging from 49.91 to 35.24. The average Simpson’s Diversity Index (1/D) is 2.88, Shannon Weiner’s Index is 0.85, species evenness is 0.57 and species richness is 1.07. The overall regeneration of the different species was seedlings 6484 individuals/ha., saplings 533 individuals/ha. and adults 1198 individuals/ha. showing fair regeneration. The majority of tree species show fair regeneration status (32.14%) followed by none regeneration (25%), new regeneration (17.85%), poor regeneration (14.28%) and good regeneration status (10.71%). The density diameter curve of the forest shows slightly flat reverse j-shaped structure indicating that majority of tree species were not in good regenerating status. The present analysis thus revealed that the population structure may get altered in future. Those species with none to poor regeneration status should be prioritized for the conservation and the proper management strategies need to be developed for sustainability of tree species in the forest.

Medicinal and aromatic plants (MAPs) are one of the most important components of non-timber forest products. This study aims to assess the collection, cultivation and harvesting, processing and trade scenario in Makawanpur district. Information gathered from the field visit to the study area, focus group discussion, key informant interviews and relevant literature were analyzed. In addition to the multiple subsistence uses of MAPs, some 30 species were also having trade value. Major MAPs species were collected from the wild whereas a few species like Asparagus, Cinnamomum, Myrsine, etc. were practiced for cultivation. Most of the MAPs were traded mainly to the Indian market without or just following a simple value addition. Except for Taxus and Berberis, none of the species was used for processing at the commercial level. The trade scenario showed a decreasing trend in both volume and value in the last few years. The unpredictable fluctuation in the market price of the products, the trader-controlled market and quality of the product, the weak bargaining power of the producer and disease and pest were found to be the major challenges faced by the local farmers.

The algal flora of Barju Taal (Lake) has been studied in 2017-18 AD. The lake is situated in Barju Rural Municipality, Sunsari District, Eastern Nepal about 12 km west of Biratnagar covering an area of 101.6 hectares. Algae were collected by squeezing submerged aquatic plants. A total of 105 algae under 51 genera have been reported. The largest phylum was chlorophyta (76 species) followed by bacillariophyta (16 species), cyanobacteria (11 species) and euglenozoa (2 species). Similarly, the largest genus was Cosmarium (22.85%) followed by Staurastrum (8.57%) and Euastrum (4.76%). Algae common to Barju Taal were Dictyosphaerium pulchellum, Ankistrodesmus falcatus, Closterium dianae, Euastrum elegans, Actinotaenium subglobosum, Cosmarium quadrum, C. ralfsii, Staurodesmus unicornis, Staurastrum sonthalianu and S. striolatum. Old Barju Taal was rich in algae than the newly constructed one. Further study of algae in different seasons compared with water parameters is recommended

Cold desert landscape of Ladakh holds endemic and unique biodiversity of ethnobotanically important medicinal plants. These medicinal plants have been regarded as rich resources of traditional medicines since the advent of human civilization. As a result of rugged terrain, inaccessible landscape, harsh climate and lack of medical facilities in the region, the indigenous community is totally dependent on the local flora for healing. Study was based on seasonal reconnaissance surveys in years 2021 and 2022. 35 villagers were questioned based on semi-structured questionnaire to record ethnobotanical information. It enumerates 32 important and unique plant species. Asteraceae (6 species) is the most dominant family followed by Polygonaceae (3 species), Scrophulariaceae (3 species), Apiaceae, Fabaceae, Ranunculaceae and Rosaceae, each representing 2 plants; whereas the other families were represented by single taxa. The habit of the plants comprised a majority of 27 herbs, 3 shrubs and 2 trees. 15 plants among them were exclusively utilized for medicinal purpose only. Enumeration of the medicinal plants along with their usage will act as the baseline data for further chemical investigation of plant constituents in pharmacological industries. This current information on plants used by native communities could be promulgated to the new generation for awareness and sustainable utilization of plants. The festivity with which they celebrate the flowers in spring time is a valuable heritage and conservation ethos, which needs to be understood by the new generations.

The mycotaxa belonging to Erysiphales reported from Nepal since 1966, are revised based on 20 published papers. The recent moleculer and phyllogenetic analysis have done several changes in the nomenclature of several powdery mildew species reported earlier from Nepal. Some were erroneously reported, while some species have undergone synonyms. Near about eighteen species of Oidium (anamorphic: imperfect stage) reported earlier still need collections, examination and study are not incorporated here. The present checklist provides corrections to misidentified species with their current (authentic) or valid names and some additons have been made based on publications. The list also records three endemic species. So, the revision includes 13 genera and 53 species parasitic on 76 flowering plants gathered from different areas of Nepalese Himalayan belt.
