Title : Morphological plasticity of corms in enhancing invasion of Chromolaena odorata Material Type: printed text Authors: JOSHI, C., Author ; J van Andel, Author ; SKIDMORE, A.K., Author Publication Date: 2011 Article on page: 3-12 p. Languages : English (eng) Abstract: In this paper, the researchers investigate the vegetative growth of Chromolaena odorata and the
influence of light intensity on the understorey environment of Shorea robusta forest at Chitwan in
south-central Terai, Nepal. C. odorata is a clonally growing shrub and typically consists of
several clones with an underground “cormous organ” (a modified stem to store food reserve; here
after “corm”) belonging to an identical genet. In C. odorata, the biomass of such corms varied
across the light gradient. The number of shoot demonstrated a strong logarithmic relation with
biomass of corm. Under open forest canopy environment, corm biomass was strongly correlated with
the number of shoots and the corm’s age. However, under dense forest canopy, there was no
significant relationship between corm biomass and its age. This result shows that corms of C.
odorata were capable of maintaining their viability for a long period even under closed canopy
environment. Any disturbances in forest canopy density would ultimately trigger its clonal growth
capability. This plasticity of corms appeared to be a key strategy for invasion success of this
species. Comparison of these results further indicates the importance of canopy density in
determining invasion success of C. odorata.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=1

Title : Modelling height-diameter relationship for Pinus wallichiana trees for Lete and Kunjo of Mustang district Material Type: printed text Authors: B.H. Wagle, Author ; SHARMA, R.P., Author Publication Date: 2011 Article on page: 13-23 p. Languages : English (eng) Keywords: Blue pine height-diameter models modelling Mustang district Abstract: Quantification of height-diameter relationship helps in better understanding of stand dynamics.
Height-diameter models can be used as necessary inputs to growth and yield models and growth
simulation systems. The researchers developed height-diameter models with 364 Blue pine (Pinus
wallichiana) tree data from Lete and Kunjo Village Development Committees (VDCs) of Mustang
district. Eighteen non-linear models were calibrated, among which, Weibull model described the
largest proportion of height
variation (R2
adj
= 0. 9362). Gunary and Chapman-Richards’ models also appeared
almost identical to Weibull model in terms of fit statistics and graphical appearance. The
researchers recommend Weibull model for predicting total heights of Blue pine trees for the VDCs
covered by the study.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=2

Title : Distribution and availability of raw materials for production of Nepali handmade paper from Daphne species in Darchula district, Nepal Material Type: printed text Authors: D. K. Kharal, Author ; OlI, B.N., Author ; I Poudel, Author Publication Date: 2011 Article on page: 24-30 p. Languages : English (eng) Keywords: Annual yield Non Timber Forest Product rotation Range post sustainable production Abstract: The study, conducted in 2005 in Darchula district of the far western region of Nepal, aimed at
assessing the distribution of Lokta plants (Daphne species) and the sustainable availability of
their bark as a raw material for Nepali handmade paper. Stratified random sampling design was
adopted for collecting primary data from 340 circular shaped sample plots. The study revealed
asymmetric distribution and production of Lokta in different Range post areas of Darchula district.
While the tree diameter at 30 cm from base (D30) varied from 1 to 18 cm, the maximum tree height
varied from 2.1 to 6 m. On the basis of diameter class, about 87 % of the bark weight was found to
be of exploitable category. For the entire district of Darchula, the annual yield of Lokta bark for
six years rotation amounted only to about two-third of the four years rotation. The study concludes
that the stock of Lokta bark that prevails in the district can sustain promotion of Nepali paper
production enterprises.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=3

Title : Medicinal plant knowledge of the Panchase region in the Middle Hills of the Nepalese Himalayas Material Type: printed text Authors: BHATTARAI, K.R., Author ; R. E. Maren, Author ; CHAUDHARY, R.P., Author Publication Date: 2011 Article on page: 31-39 p. Languages : English (eng) Keywords: Ethnobotany Panchase medicinal plants ailments Abstract: Use of plants as medicine has been practiced all over the world since the dawn of human
civilisation. In the Himalayas, many medicinal plants yield essential ecosystem services/ benefits
for the subsistence farmers, many of which grow in the forest ecosystem. However, documentation of
traditional medicine and medicinal plants used by local communities is rather poor in Nepal.
Panchase forest, Central Nepal, is home of many wild plants, used in traditional medicine, and a
livelihood source for many ethnic groups. This study was conducted to document medicinal plant
knowledge and plant use in the treatment of different ailments. To explore the ethnobotanical
knowledge interviews were conducted with local healers, plant traders and knowledgeable villagers.
The study provides information on 45 plant species, belonging to 32 families under 44 genera. The
studied medicinal plants were found to be useful for treating 34 different ailments. The study
which has 57% resemblance with previous studies. We conclude that a wealth of ethnobotanical
knowledge still persists in the Panchase region. However, due to land use change and migration it
needs to be preserved for the future through extensive publications and disseminations.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=4

Title : Using Landsat data for assessing forest cover change and fragmentation in Laljhadi corridor of Kanchanpur district, Nepal Material Type: printed text Authors: R. R. Aryal, Author ; H. L. Shrestha, Author ; S. Khanal, Author Publication Date: 2011 Article on page: 40-44 p. Languages : English (eng) Keywords: Fragmentation forest cover chang;, Landsat Laljhadi corridor Abstract: The study, carried out at Laljhadi corridor in Kanchanpur district of Nepal, aimed at assessing
forest cover change and fragmentation using multi-temporal Landsat data. Post classification change
detection was applied on temporal forest cover class datasets obtained by supervised classification
technique with maximum likelihood algorithm. The overall change analysis indicated a decreasing
trend in forest cover. Statistics on selected landscape metrics were generated to quantify the
change in spatial structure resulting from fragmentation. The analysis of the landscape metrics

Title : Utilization of plant resources in Dang district, West Nepal Material Type: printed text Authors: S. R. Sigdel, Author ; ROKAYA, MAAN B., Author Publication Date: 2011 Article on page: 45-54 p. Languages : English (eng) Keywords: Dang district, ethnobotany medicinal plants vulnerability test Abstract: This paper aims to highlight the uses of forest resources in Purandhara, Panchakule and Goltakuri
Village Development Committees (VDCs) of Dang district, western Nepal. The ethnobotanical data was
collected through Participatory Rural Appraisal (PRA) that involved discussion with local people
and key informants, through semi-structured questions and informal conversations. Vulnerability of
plants used in the study area was assessed by adapting the Rapid Vulnerability Approach (RVA).
Altogether 85 plant species belonging to 79 genera and 56 families were recorded in the study
areas. Twelve plant species were found to be used for various purposes other than medicinal. They
were used as food, fodder, in construction, in religious purposes and even in yielding dyes.
Seventy three plant species were found to be medicinal in properties for treating
144 different ailments. Remedies for 27 ailments were reported as new uses. The most common way of
admission of medicine was oral (76.71 %) followed by external or topical (35.6 %) and nasal (1.27
%). The RVA test showed Dalbergia sissoo (with 15 scores) and Terminalia alata (with 14 scores) as
most vulnerable ones.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=6
