The landslide triggering factors were investigated followed by the thematic maps and landslide distribution map prepared and classified using the GPS and GIS Softwares like CartaLinx, ArcView and ERDAS IMAGINE in Sarangkot and Kaskikot Village Development Committees, Kaski district. In analytical hierarchy process, the factors for zonation were compared by Couple Comparison Method and their weights were determined using Arithmetic Mean Method and earned weight values of each factor. The landslide hazard zonation model was employed to prepare landslide hazard zonation map of the study area, and then classified into five relative hazard classes using the equal interval classification method. Finally, the landslide hazard zonation map was crossed with the landslide distribution map and the model applicability was confirmed by determining the per hazard class percent of area covered by the landslide. In the land hazard zonation map, 0.44% of the study area was in very low hazard, 2.11% in low hazard, 54.92% in moderate hazard, 21.34% in high hazard and 21.19% in very high hazard area. The major portion of the study area was on the moderate zone whereas the least portion was on the very low hazard zone. In the study area, most of the high and very high hazard class areas were found occupying the areas closer to the linear triggering factors like presence of linement and fault, presence of motorable road and presence of rivers and streams. The landslide density of the study area was found to be 0.44 per km2 indicating the higher hazard susceptibility of the area.DOI: http://dx.doi.org/10.3126/banko.v22i2.9198Banko Janakari: A Journal of Forestry Information for NepalVol. 22, No. 2, 2012 November Page: 43-52 Uploaded date: 12/1/2013

The study assessed NPK (Nitrogen, Phosphorus, Potassium) transferred through litter from forest to farmlands, forest product extraction systems and farmers' perceptions on forest dependency for maintaining farm fertility in Lete and Kunjo, Mustang (high mountain) and Tibrekot, Kaski (mid-hill region), Nepal. NPK in composite samples of forest litter were determined by standard methods.

This paper focuses on the ecological status and diversity indices: Simson’s Index (C), Simson’s Index of Dominance (D) and Shannon-Weaver Index (H) of Dactylorhiza hatagirea and its associates- Rheum australe and Rumex nepalensis in Lete village of Mustang District within the Annapurna Conservation Area. The study was conducted during the monsoon season (June/July) of 2013 in the Lete VDC of Mustang District. The study site possessed an area of 4.5 ha. Altogether, 100 circular plots, each with 25 m2 area, were laid out purposively within the study area; the sampling intensity being 5.55%. The relative frequency, the relative density, the abundance, the relative coverage and the Important Value Index of the species were found to be 61.11, 53.91, 1,061.54, 72.2 and 187.24 respectively. Similarly, the Simson’s Index (C), the Simson’s Index of Dominance (D) and the Shannon-Weaver Index of the species were found to be 0.41, 0.59 and 3.27 respectively, indicating relatively even and relatively diverse community. The study showed relatively higher values of all the parameters of D. hatagirea as compared to its associates indicating good ecological value. However, threats remain due to the illegal harvesting of this valuable orchid and overgrazing in the study site.Banko JanakariA Journal of Forestry Information for NepalVol. 26, No. 1, Page: 45-52, 2016
