Title : Effects of the environment on species richness and composition of vascular plants in Manaslu Conservation Area and Sagarmatha region of Nepalese Himalaya Material Type: printed text Authors: RAI, S.K., Author ; SHARMA, S., Author ; J. P. Gajurel, Author ; SHRESTHA, K.K., Author ; M. P. Nobis, Author ; C. Scheidegger, Author ; S. Devkota, Author Publication Date: 2016 Article on page: 3-16 p. Languages : English (eng) Keywords: Canonical correspondence analysis, elevation, generalized linearmodel, land use types, multivariate analysis, species richne Abstract: This study analyzed how the environmental conditions constrained the species
richness and composition in the four river valleys of Central Nepal i.e. two from
Manaslu Conservation Area (MCA) and two from Sagarmatha region. Topographical,
bioclimatic and measured variables were used to analyze their effects on the
vascular plant diversity along elevation and land use gradients. Altogether, 148 plots
were established at five elevation levels between 2,200 m and 3,800 m above the
mean sea level. Four land use types namely crop field, meadow, exploited forest
and natural forest were sampled at each elevation level. Altogether, 790 species of
vascular plants belonging to 114 families were recorded; Asteraceae had the highest
number of species (84) followed by Rosaceae (52) and Poaceae (50). Explorative
data analysis of species composition by canonical correspondence analysis (CCA)
showed that the topographical variables explained the composition better than both
the bioclimatic set of variables and the logger data. However, all groups of variables
revealed significant effects on species composition. Generalized Linear Model
(GLM) also revealed significant effects of elevation, land-use types, slope angle,
aspect, temperature and precipitation on species richness.ssLink for e-copy: http://lib.frtc.gov.np/elibrary/?r=573

Title : Mapping deforestation and forest degradation using CLASlite approach in Eastern Churia of Nepal Material Type: printed text Authors: S. Khanal, Author ; A. Khadka, Author Publication Date: 2016 Article on page: 17-23 p. Languages : English (eng) Keywords: Churia, CLASlite, deforestation, forest degradation, spectral mixtureanalysis Abstract: Monitoring deforestation and forest degradation is essential for forest conservation
and sustainable management. Those activities have become more relevant in order
to get reference emission level required for Reducing emissions from deforestation
and forest degradation (REDD) initiative. The study aimed to assess forest
degradation and deforestation in the Churia region of Eastern Nepal using CLASlite
approach. This approach is based on Spectral Mixture Analysis and provides
highly automated technique for forest cover, deforestation and forest degradation
mapping. The Landsat imageries of 2002 and 2013 were processed for estimation
of deforestation and forest degradation. The validation of results based on the
high-resolution multi-temporal Google Earth imageries and the field sample plots
indicated that CLASlite approach could be feasible approach to monitor forests for
deforestation and degradation. The results can be further improved by including
more frequent time-series observation from Landsat.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=574

Title : Comparative study on carbon stock in Sal (Shorea robusta) forest in two different ecological regions of Nepal Material Type: printed text Authors: H. P. Pandey, Author ; M. Bhusal, Author Publication Date: 2016 Article on page: 24-31 p. Languages : English (eng) Keywords: Biomass carbon, carbon stock density, ecological regions, Shorea robusta,soil organic carbon Abstract: ecological and economic benefits through various environmental services. With an aim
to quantify the carbon stock densities in the two different ecological regions–the Hills
and the Terai, two Community Forests (CFs) having the dominance of Shorea robusta
were selected from Gorkha (in the Hills) and Chitwan (in the Terai) districts for the
purpose of the study. Systematic random sampling with 1% sampling intensity was
used to collect necessary data. The total carbon stock in the CFs of the Hills and the
Terai were found to be 234.54 t ha-1 and 479.29 t ha-1, respectively. The biomass carbon
stock density in the CF of the Terai was found to be higher (384.20 t ha-1) than the one in
the Hills (123.15 t ha-1). Carbon densities of different carbon pools such as tree; sapling;
leaf litter, grass and herbs were significantly higher (P forest whereas dead wood and stumps and the soil organic carbon density were found
to be not significantly different in these regions. Similarly, the highest amount of soil
organic carbon (SOC) was found in the uppermost soil horizon in the forests of both the
regions. These results revealed that the biomass carbon stock density was higher in
the Terai S. robusta forest than in the Hill S. robusta forest. However, the SOC obtained
was in inverse relation to that of the biomass carbon stock in both the ecological
regions. It would not be biased if different ecological regions with similar forest types
are intervened with different management strategies for having more carbon stocks
and for the conservation of biodiversity in the days to come.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=575

Title : Forest type mapping using object-based classification method in Kapilvastu district, Nepal Material Type: printed text Authors: A. K. Chaudhary, Author ; A. K. Acharya, Author ; S. Khanal, Author Publication Date: 2016 Article on page: 38-44 p. Languages : English (eng) Keywords: Landsat, machine learning algorithm, object-based classification Abstract: In the recent years, object-based image analysis (OBIA) approach has emerged with
an attempt to overcome limitations inherited in conventional pixel-based approaches.
OBIA was performed using Landsat 8 image to map the forest types in Kapilvastu
district of Nepal. Systematic sampling design was adopted to establish sample points
in the field, and 70% samples were used for classification and 30% samples for
accuracy assessment. Landsat image was pre-processed, and the slope and aspect
derived from the ASTER DEM were used as additional predictors for classification.
Segmentation was done using eCognition v8.0 with the scale parameter of 20, ratios
of 0.1 and 0.9 for shape and color, respectively. Classification and Regression Tree
(CART) and nearest neighbor classifier (k-NN) methods were used for object-based
classification. The major forest types observed in the district were KS (Acacia catechu/
Dalbergia sissoo), Sal (Shorea robusta) and Tropical Mixed Hardwood. The k-NN
classification technique showed higher overall accuracy than the CART method. The
classification approach used in this study can also be applied to classify forest types
in other districts. Improvement in classification accuracy can be potentially obtained
through inclusion of sufficient samples from all classes.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=577

Title : Identification of land reclamation area and potential plantation area on Bagmati river-basin in the Terai region of Nepal Material Type: printed text Authors: A. K. Acharya, Author ; A. K. Chaudhary, Author ; S. Khanal, Author Publication Date: 2016 Article on page: 53-59 p. Languages : English (eng) Keywords: Bagmati river basin, land reclamation, object-based image classification,potential plantation area, Terai Abstract: Utilization of land reclamation area offers the potentiality of increasing greenery as
well as providing forest products. This study refers to the identification of the land
reclamation areas and potential plantation areas on the Bagmati river-basin in the
Terai region of Nepal, and recommends appropriate species for plantation in order
to rehabilitate such areas. Multi-temporal Landsat Satellite Images (Landsat 7 and
Landsat 8) were acquired for 2002 and 2014. Object-based Image Classification
method was used to classify the land cover classes into four broad categories: i) Water,
ii) Sand and gravel, iii) Plantation potential (open areas suitable for plantation) and
iii) Others (forest, agriculture, built-up areas etc.). The Mean Normalized Difference
Water Index (NDWI) values and Mean Brightness values were found to be helpful in
identifying the water and sand & gravel areas from the other land cover classes. The
overall classification accuracy was 0.97 with a kappa coefficient of 0.89 in the case of
the 2014 Image classification. In this study, the land reclamation area referred to the
areas occupied by water, sand & gravel on the river-beds that were converted into
plantation potential and other classes between 2002 and 2014. Similarly, the potential
plantation area referred to the summation of the area of reclaimed land, the area of
‘Others’ class converted into ‘Plantation potential’ class and the area that remained
to be plantation potential on the bed of the Bagmati River and its tributaries between
2002 and 2014. Altogether, 4,819.10 ha land was reclaimed in the study area, and a
total of 5,395.10 ha land was found to be potential for plantation within the study area.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=579

Title : Estimating tiger and its prey abundance in Bardia National Park, Nepal Material Type: printed text Authors: KARKI, J.B., Author ; Y. V. Jhala, Author ; B. Pandav, Author ; S. R. Gyawali, Author ; SHRESTHA, R., Author ; K. Thapa, Author ; THAPA, G., Author ; N. M. B. Pradhan, Author ; B. R. Lamichhane, Author ; S. M. Barber-Meyer, Author Publication Date: 2016 Article on page: 60-69 p Languages : English (eng) Keywords: Bardia, camera trap, density, line transect, tiger, wild prey Abstract: We estimated tiger and wild prey abundance in the Bardia National Park of Nepal.
Tiger abundance was estimated from camera trap mark recapture in 85 days
between December, 2008 to March, 2009 by placing 50 camera trap pairs in 197
trap locations with a sampling effort of 2,944 trap nights. We photo captured 16
individuals (≥1.5 year old) tigers identified on the basis of their unique stripe patterns.
The number and density (per 100 km2) of tiger was 19 (SE 3.3) and 1.31 (SE 0.32),
respectively. Distance sampling was used to assess the prey abundance on 170
systematically laid line transects between May–June, 2009. The density of all the
wild prey (individuals/km2) was 56.3 (SE 6.5). The density (individuals /km2) of Chital
was 29.3 (SE 4.3). The density of barking deer, wild pig and sambar were in higher
to medium, medium and medium to low range as compared to other protected areas
in South Asia respectively. The study indicated decline of tiger in Bardia National
Park even though the existing level of the prey population appears to be adequate
to support higher tiger numbers. There is hope of meeting the ambitious goal of
doubling the tiger population by 2022 set by the Tiger Range Countries which was
evident in 2014 with 50 tigers in Bardia National Park and Khata Corridor. The tiger
habitats outside the protected areas should be managed with the local community-
based initiatives to ensure the acceptance of low density tiger movement.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=580

Title : Impact of roads on biodiversity: a case study from Karekhola rural road in Surkhet district of Nepal Material Type: printed text Authors: J. K. KC, Author ; GAUTAM, AMBIKA PRASAD, Author Publication Date: 2016 Article on page: 70-77 p. Languages : English (eng) Keywords: Community forests, Middle Hills, rural road, woody plant species’ diversity Abstract: Loss and degradation of biodiversity is continuing despite the past conservation
efforts in Nepal. Out of many potential causes, this study strives to investigate the
effects of a road project on biodiversity in the Middle Hills of Nepal. Information about
floristic composition was collected from the adjoining community forests using group
of 30 circular sample plots, each located at 50 m and 20 m far from the edge of the
road. Results provide evidence that rural road projects are contributing to reduction
of biodiversity which may be due to the removal of low-yielding timber species near
the road-edge. The study also suggests that proximity to road-edge reduces under-
storey vegetation which will lead less capable forest to sustain its original biodiversity.
However, silvicultural operations have potential to minimize the indirect loss of
biodiversity caused by road projects.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=581

Languages : English (eng) Keywords: Basal area, invasion, Mikania micrantha, plant diversity Abstract: Mikania micrantha is considered to be the most problematic in terrestrial ecosystem
in Eastern and Central Nepal. Despite the current situation of the Mikania invasion,
quantitative data on the impacts and scale of the problems are lacking for the country.
Due to the lack of information regarding scale of invasion, the stakeholders have not
put forwarded the proper control mechanism of the species. This paper has made an
attempt to analyze the scale of invasion through the comparison of plant biodiversity
and basal area per hectare as the significance of stand structure between Mikaniainvaded
and non-invaded tropical Shorea robusta forest areas. This study was
conducted in Barandabhar Buffer Zone Forest of Chitwan National Park. Sampling
and measurement was conducted in both the invaded and non-invaded forest areas.
The stand structure of both the invaded and non-invaded areas were compared in
terms of different parameters like seeding density, sapling density, pole basal area
per hectare and tree basal area per hectare. Statistical analysis showed that there is
significant impact of Mikania on plant diversity at seedling and sapling stages. There
is negative effect of Mikania on stand structure of the forest. Hence, there is urgent
need to control the invasive weed so as to control further invasion and to conserve
biodiversity and productivity.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=582

Title : Microbial inoculant influences the germination and growth of Albizia lebbeck seedlings in the nursery Material Type: printed text Authors: B. M. Khan, Author ; M. A. Kabir, Author ; M. K. Hossain, Author ; M. A.U Mridha, Author Publication Date: 2016 Article on page: 82-89 p. Languages : English (eng) Keywords: Albizia lebbeck, germination, microbial inoculant, seedling growth Abstract: Microbial inoculants (MI), a biofertilizer, composed of many different beneficial
microorganisms has positive role on seed germination and growth of plants. In the
present study, its efficacy on seed germination and seedling growth of Albizia lebbeck
in the nursery was studied. The seeds were sown in polybags filled with a mixture of
forest soil and cow dung (3:1) and treated with 0.1%, 0.5%, 1%, 2%, 5% and 10%
concentrations of MI. Most of the parameters studied (seed germination, shoot and
root lengths, dry weights of shoot and root, collar diameter, leaf number etc) were
found maximum in 2% of MI . Although the highest vigor index, volume index and
quality index (7053, 3738 and 1.106, respectively) were found in 2% MI, but the
highest sturdiness (65.95) was found in 1% MI solution. The nodule number was
higher at a very low (0.5%) concentration of MI but it normally decreased with the
increase of concentration. Total pigment content in leaf was recorded highest (112.86
mg.L-1) in 2% of MI. Therefore, MI influences seed germination and seedling growth
of A. lebbeck and the low concentration (2%) of the inoculant can be recommended
for getting maximum seed germination and seedling growth of the species studied.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=583

Title : Drivers and dynamics of land use land cover in Ambung VDC of Tehrathum district, Nepal Material Type: printed text Authors: PANDEY, D., Author ; BP Heyojoo, Author ; H. Shahi, Author Publication Date: 2016 Article on page: 90-96 p. Languages : English (eng) Keywords: Forest cover, geographic information system, remote sensing, supervised classification Abstract: Land use and land cover change has immense impact on the global environment
and ecosystem. Geospatial technologies are very important for monitoring these
changes. This research aims to find out the land use land cover dynamics and drivers
of Ambung VDC, Tehrathum district. The Landsat images of the year 1990 and 2013
were used for quantifying the changes. Household survey, key informant interview,
focus group discussion, training samples collection and direct field observations
were carried out to gather socio-economic and bio-physical data. Supervised
classification was performed to prepare land cover maps. Change on land use was
calculated by using post classification change detection. During 1990–2013, forest
cover was found to have increased by 6.6%, agriculture decreased by 5.9% and
others (barren, settlement, grass, rock and water bodies) decreased by 0.7%. The
VDC was found to have severe problem of rapid drying of water resources in spite
of the increase in forest cover, and so research should be carried out to find out the
reason and solve the problem before it is too late.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=584

Title : Resource assessment of Bel (Aegle marmelos) and potentiality to establish its processing enterprise in Tanahun district of Nepal Material Type: printed text Authors: K. BARAL, Author ; B. R. Upreti, Author Publication Date: 2016 Article on page: 32-37 p. Languages : English (eng) Keywords: Aegle marmelos, enterprise, regeneration protection Abstract: Participatory resource assessment of Aegle marmelos was carried out in six
community forests (CFs) of the Jamune VDC of Tanahun district to find out potentiality
for establishing community-based A. marmelos processing enterprise in the locality.
Circular sample plots of 500 square meters were laid down taking 5% sampling
intensity. The DBH (Diameter at Breast Height) and height of trees on the sample
plots were measured and classified them into three DBH classes (10–20 cm, 20–30
cm and more than 30 cm). The number of the fruits on the three branches of each
A. marmelos tree – one lower branch, one middle branch and one top branch were
counted, the average number of fruits on the three branches calculated and multiplied
with the number of the branches of the tree to find out the average number of fruits
per tree. By calculating the weighted mean of the three different DBH-class trees, the
total number of the fruits was estimated. The study found 54,830 kg of harvestable
amount of A. marmelos fruit in the studied six CFs which can produce 19190.5 kg of
pulp per year. Thus, establishment of juice processing enterprise was found to be
feasible in the locality. Nevertheless, some shortcomings related to the management
of A. marmelos resource, such as lacking of information and management options
for A. marmelos trees in the Operation Plans (OPs), lower regeneration status of
A. marmelos trees, higher incidences of forest-fire and open grazing in the CFs,
were also recorded. The study suggests for carrying out awareness-generating
activities targeted to the CF user group members, revision of OPs and incorporation
of A. marmelos resource information and management options and preparation and
implementation of regeneration protection plan against forest fire and grazing.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=576
