Title : Above-ground tree biomass and allometric relationships of Cinnamomum tamala grown in the western hill regions of Nepal Material Type: printed text Authors: B. S. Poudel, Author ; GAUTAM, S.K., Author ; D.N. Bhandari, Author Publication Date: 2011 Article on page: 3-12 p. Languages : English (eng) Keywords: Regression models fresh weight bark foliage branch wood stem wood Abstract: Biomass regression models are presented describing total above-ground biomass, stem wood, branch
wood, foliage and bark production for Tejpat (Cinnamomum tamala), a multi- purpose tree which is
found abundantly distributed and grown in western hill districts of Nepal. A total of 56 Tejpat
trees between 6.2 and 16.5 cm diameter at breast height (DBH) from farmers’ farmland and marginal
land in Arghakhanchi, Gulmi and Palpa districts were sampled and harvested. Mean fresh weight of
total above-ground biomass, stem wood, branch wood, foliage and bark was 77.03, 36.39, 15.16, 17.53
and 8.2 kg tree -1, respectively. Allocation of biomass was more in stem (47.24% tree-1) than in
foliage (22.75% tree-1), branch (19.69% tree-1) and bark (10.31% tree-1). Weight of tree component
was estimated as a function of DBH. After removal of the outliers, data were randomly divided into
two datasets: 70% for model calibration and another 30% for model validation. Correlation analysis
showed positive stronger linear relationship between DBH and biomass. Five regression models
(linear, logarithmic, quadratic, power and exponential) were developed. All models were
statistically significant, with R2 ranging from 0.64 to 0.83. Model validation was based on root
mean square error (RMSE). RMSE percentage for the best-fit equation varied between 16.64% and
44.82%. Linear model resulted in the least error and was selected as the best-fit model for
prediction of biomass of bark, foliage, branch, stem and total above ground tree biomass. Biomass
models developed could be applied to obtain biomass of different tree components of Tejpat grown in
the study area and could even be applied to other areas which have similar conditions; but it
should be validated before using them in new sites and conditions.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=7

Title : Distribution and utilization of bamboos in the mid-western and the far- western regions of Nepal Material Type: printed text Authors: DAS, A.N., Author ; THAPA, H.B., Author Publication Date: 2011 Article on page: 13-24p Languages : English (eng) Keywords: Distribution, utilization, bamboo, district, region Abstract: The distribution and utilization of bamboo species in the mid-western and the far-westernregions were recorded using various methods including Rapid Rural Appraisal (RRA) andParticipatory Rural Appraisal (PRA) tools, field visits and specimen collection. Of the elevengenera of bamboo recorded from the regions, most of the species were found to be ofindigenous types. In the mid-western region, 48 bamboo species were recorded: 18 identifiedat species level and 11 at genera level. However, 19 species could not be identified, althoughtheir local names were recorded. Similarly, in the far-western region, 31 species wererecorded: 10 were identified at species as well as genera levels. In this region too, 11species could not be identified, only local names were recorded. Greater diversity ofbamboos exists in the hills than in the Terai belt of the regions studied. High Mountaindistricts such as Jumla, Dolpa, and Darchula contain considerably less quantity of largediameter sized bamboos (bans) than small sized diameter bamboos (nigalo). Although, inthese regions, 18 uses of bamboo were noted, many species are mostly used for weaving.The development of bamboo resources in the regions can help reduce poverty, generateemployment and sustain rural livelihoods.

Title : Status of blue sheep and Himalayan tahr in Dhorpatan Hunting Reserve, Nepal Material Type: printed text Authors: KARKI, J.B., Author ; THAPA, B.B., Author Publication Date: 2011 Article on page: 25-30 p Languages : English (eng) Keywords: Blue sheep Dhorpatan Hunting Reserve Himalayan tahr hunting quota;population density Abstract: A survey of blue sheep (Pseudois nayaur) was conducted in six blocks of Dhorpatan Hunting
Reserve (DHR), Nepal. A total of 852 blue sheep were recorded in 73 different groups. The
average group size was found to be 11.7 individuals. The average population density of blue
sheep in the reserve was found to be 1.28 animals per km2. There were 263 rams, 307
ewes, 89 yearlings and 39 lambs. Among the rams, 126 were classified as trophy rams, 92
as medium rams and 45 as young rams. The ratio of trophy rams to other rams was found
to be higher than those found in the earlier studies. The mean sex ratio was 86 males per
100 females and the yearling to ewes ratio was 29 per 100 ewes. The survey of Himalayan
tahr (Hemitragus jemlahicus) in Sundaha block recorded 53 individuals with 30 males, 14
females, eight yearlings, and one lamb. The results indicated that the existing quota of
blue sheep hunting can be safely continued. In case of higher demands, two more quotas
can be added to Barse, Dogadi and Sundaha blocks for the next five years (2008-2012).
Himalayan tahrs can be hunted in all the blocks. Sundaha block can sustain four while the
rest of the blocks can sustain two Himalayan tahrs per year.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=14
