Title : An assessment of tree species dynamics in rural farmland of Nepal Material Type: printed text Authors: D. K. Kharal, Author ; OlI, B.N., Author Publication Date: 2007 Article on page: 3-10 p. Languages : English (eng) Keywords: Composition, Diversity, Dynamics, Farmland, Socioeconomic factors, Trees. Abstract: Dynamics of species distribution, species composition and species number are very important areas to be understood for sustainable management of forest and tree resources. The paper endeavours to solicit information on dynamics of tree species in terms of their composition and number, and also assesses the relationship between socio-economic factors and tree species dynamics. The study was conducted through survey of 98 sampled households, focus group discussion and direct field observation. Species composition and species number of tree resources of the study area are identified for different time period. The study found out that proportion of tree species loss on farmland was higher than that of species introduction. Similarly, 20 species were found with very limited distribution in the study area while two of them are already under the threatened category at the national level. The reasons for species change in the farmland are also identified. Farmers are now attracted to grow fast growing, multipurpose and easily available tree species. Economic return is the major concern for them. Such a situation may lead to further loss of tree species from the farmland. Some species such as Shorea robusta and Phyllanthus emblica, which were among the widely distributed in the beginning, are now about to be lost because of easy availability in nearby forest, slow growth rate and limited uses.

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 : An Estimation of Tree Species Diversity in Rural Farmland of Nepal Material Type: printed text Authors: D. K. Kharal, Author ; OlI, B.N., Author Publication Date: 2008 Article on page: 3-10 p. Languages : English (eng) Keywords: Farmland, Forest, Homegarden, Nepal, Species Diversity, Richness, Trees. Abstract: Biodiversity is an important consideration in maintaining natural environmental balance in a particular habitat. This becomes particularly important in areas, where due to the encroachment of natural forests, biodiversity is depleting causing a potential loss in the natural habitat. In such a situation, biodiversity in the farmland becomes an important consideration. Biodiversity is measured and analyzed using various indices. In this study, we present the result of our study through a field work in a rural village in Nepal. The study was conducted through direct field observation and survey of sampled households. The status of tree biodiversity using species biodiversity index and species richness index for the case study are presented. The study has also identified the relationship between the tree species diversity and major socioeconomic factors. Our analysis shows that tree species biodiversity in the rural farmland of study area are lower in comparison to the similar areas of countries like India, Bangladesh and Sri Lanka. The lower biodiversity status is mainly due to the wide distribution of two dominating tree species of Dalbergia sissoo and Melia azederach. Similarly, Tree species biodiversity in the farm land has been found affected by the socioeconomic situation of the area. Further study is suggested by involving more socioeconomic factors and covering a large sample size and time of study. Link for e-copy: http://lib.frtc.gov.np/elibrary/pages/view.php?ref=76&k=
