Mahakali river system was flanked by a number of tributaries, steep cliffs, rocks, and was closely associated with riverine and mixed Shorea robusta (Sal) forests, resulting in richness and diversity of habitats and plant species. Vegetation succession was found to conspicuous as transcends farther from river edge, the Phragmites karka was gradually succeeded by Saccharum spontaneum and riverine forest species such as Acacia catechu, Dalbergia sissoo, Bombax ceiba, Eugenia jambolina , Aegle marmelos, etc. A total 140 plant species including 78 ethnomedicinal were inventoried, representing about 27 percent of the district flora. This study serves as a baseline data of phyto-ecological attributes of Mahakali River and can be taken as a reference to investigate the temporal changes in Mahakali River system. J. Nat. Hist. Mus.

The antibacterial activity was studied against six pathogenic bacteria, three gram negative: Klebsiella pneumoniae (ATCC 15380), Proteus mirabilis (ATCC 49132), Escherichia coli (ATCC 25922) and three gram positive: Bacillus subtilis (ATCC 6633), Enterococcus faecalis (ATCC 29212), Staphylococcus aureus (ATCC 25932) at different concentrations (50 mg/ml, 100 mg/ml, 150 mg/ml, 200 mg/ ml, 250 mg/ml) of leaf extracts of X. strumurium. The phytochemical screening depicted the presence of terpenoids, saponins, flavonoids, tannins and alkaloids. The antibacterial activity of extracts was determined by disc diffusion method and zone of inhibition (ZOI) was measured. Gram negative bacteria was found more resistant than gram positive bacteria. The most susceptible bacterium was S. aureus while the most resistant bacterium was E. coli. Methanolic extract was found more effective than distilled water. These findings suggest that extracts obtained from leaves of X. strumurium possess biobactericidal potential, which can suitably be exploited for making antibacterial drugs.J. Nat. Hist. Mus.

Melamchi River is a snowmelt and rain fed river. River water is mainly used for drinking and irrigation. Water samples were collected on monthly basis from five sites of river. Parameters analyzed include temperature, electrical conductivity, turbidity, pH, hardness, alkalinity, dissolved oxygen, calcium, magnesium, chloride, phosphate, and nitrate. The study revealed seasonal fluctuations of the factors. River water was well oxygenated and alkaline in nature. High level for turbidity (43.25/ NTU) was observed during monsoon, which exceeded compliance levels of WHO (2011) tolerance limits (5/ NTU) for domestic use. Water contained more TDS and EC indicating the impact of agriculture and deforestation near the river area. The analyzed physico-chemical parameters were found within the permissible limit of WHO, except turbidity. Measures should be taken to regulate agricultural and deforestation activities upriver to avoid advert conditions.J. Nat. Hist. Mus.

All the samples were microscopically examined by faecal floatation and sedimentation techniques. Out of 43 faecal samples, 40 samples (93.02%) were found positive for gastro-intestinal parasites. Altogether, 12 different species of gastro-intestinal parasites were recovered from Red panda. Among them, two species of protozoan parasites and 10 species of helminthes were observed. In protozoan parasites, Eimeria (67.44%) was more prevalent as compared to Entamoeba (62.79%). Among helminthes, Oxyuris sp. showed the highest prevalence rate followed by Toxoascaris sp.

These ethnic communities have been practicing the indigenous knowledge of plants for their livelihood. The objective of this study is to document the traditional knowledge of one of the most important medicinal plant species Taxus wallichiana Zucc. in different altitudinal gradients in Manaslu Conservation Area, Sagarmatha National Park and surrounding and Kanchenjunga Conservation Area. This study was carried out in six altitudinal gradients (2200 m asl to 3800 masl) with altitudinal steps of 400 m asl. We used direct observation method and standardized interviews to collect the data related to the use of T . wallichiana . Out of five caste groups, only four were local to the site while one cast had migrated from Terai region and had settled down recently. The four caste groups included Sherpa, Tamang, Rai and Gurung who have been using the plant products for various reasons. People used the species as timber, medicine for jaundice and cancer, fence, construction material for houses and cattle fodder. Knowledge of the use of T . wallichiana was mainly available at an altitude of 2600 m a.s.l., the species altitudinal distribution optimum. Most of the informants were related to community forests in the study areas and many also depend on plants for their livelihood. This study also helped the local people by informing them about sustainable use and conservation of this plant in the study areas. J. Nat. Hist. Mus.

The average 1.26/m2LiDAR point density recorded by the scanner was used to measure canopy height and build a model using LiDAR variables and model coefficients. The developed LAMP model successfully estimated the AGB of the study area. The research tells that the study area comprises almost 50% forest cover with an average 211.63 t/ha AGB.Standing carbon stock was converted from AGB by multiplying the 0.47 which is default carbon fraction. Average standing carbon stock is 99.47 t/ha in the study area. The LAMP method found that the standing total AGB was 214.85-208.41 t/ha at a 95% confidence level and the FRA field-plot AGB estimate is 210.09/ha. This correspondence at this level of confidence means that the LAMP estimates are as accurate as those of the field-based inventory. J. Nat. Hist. Mus.
