An attempt has been made in this paper to deleneate landslide prone zones of Nepal - a mountaneous Himalayan Kingdom plagued with landslide menace. The landslide Atlas of Nepal has been prepared by super imposing the lithological erodibility map of Nepal and locating the existing major landslide, on the ecological zones map of Nepal. The country has been divided into four landslide prone zooes in order of susceptibility. The landslide Atlas of Nepal can assist in containing the landslide menace.- Effect of Pinus roxburghii Plantations on the Yield and Composition of Grasses in Temperate Region

Study on grass yield and composition under two age group plantations of Pinus roxburghii and open grassland was conducted at Kyarighat, 23 km from Shimla on Shimla-Kalka road during the year 1979, 1980 and 1981 respectively. Abundance, frequency, density and I.V.I. (Improtance Value Index) of each grass species under three sites have been recorded. Maximum yield (5094.36 kg/ha/yr) has been recorded in open grassland followed by Pinus roxburghii plantations of the year 1971 (4067.23 kg /ha/yr) and the year 1953 (3415.50 kg /ha/yr) respectively in decreasing order.- Ground Water Quality (pH) Under Different Vegetative Covers at Osamund (Nilgiri Hills)

Groundwater is one of the important sources of water supply and vegetation plays its role in maintaining the quality and quantity of groundwater. However, little data is available in our country on the quality and quantity of groundwater resources as affected by vegetative. Of the many qualities of groundwater, pH measarements under different vegetative cavers was taken for studies Groundwater samples were collected at-fortnightly intervals for two years from piezemetic wells existing in three vegeative covers viz. Eucalyptus plantation, Shola forest and grassland, the samples were analysed for pH. The study indicated no adverse effect on pH of groundwater due to different vegetal covers. However, there is noticeable seasonal variation in pH values of groundwater in the rainy season (pH 5.60) the groundnater becomes more acidic than it is in the dry season (pH 6.52).- Afforestation for Avalanche Prevention and Control

Suddn downward movement of snow due to instability In the snow packs-generally known as avalanches, results in great catastrophies in the Himalayan region resulting in huge loss of life property and facilities. Afferestation is considered to be very important for any avalanche protectIon work where avalanches start within the tree zone; trees, anchor the snow and prevent the avalanche from ever happening. The present paper deals with various aspects of afforestation of avalanche prone sites to minimise avalanche occurrence on a short and long term basis. Both coniferous and Broad leaved species considered suitable for afforestation of avalanche prone sites have been listed. Guiding principles for choice of species, crop geometry, spacing required, crop height and density structures of the forest and other details have been discussed. Pre-requisities for improvement of avalanche prone areas have been given and suggestions future work made.- Wastage of Stump Wood in Terms of Energy in Spruce (Picea smithiana) and Silver Fir (Abies pindrow) Forests

The present study deals with the wastage of stump wood left over In forests at the time of tree felling for manufacture of wooden boxes for apple transportation, in the form of wood and energy in spruce (Picea smithiana) and silver fir (Abies pindrow) forests of Himachal Pradesh. Two forest divisions viz. Kotgarh and Shimla only were taken into coosideration and total wastage of wood in the form of high stumps was worked out 11910 tonnes during the year 1981 felling (after allowing 15 cm permissible stump height). In terms of energy, total calorific values of 4,94,47 × 105 K cal were recorded which is sufficient to fulfill the requirements of beating and cooking of 747 families having five members each for one year.- Litter Proouction and Release of Nutrients in Coniferous Forests of Himachal Pradesh

The present investigation deals with the litter production and nutrient tnrnover in four prominent coniferous species viz. Abies pindrow; Piceo smithiana; Cedrus deodara and Pinus wallichiano of Himachal Pradesh. Annual litter production and the amounts of nutrients released annually through litter fall bave been worked out in all the four species. A comparative account of nutrients released anually through litter fall lu different species is also prepared.- Interception Studies in Cedrus deodara Loudon Plantation in Himachal Pradesh

The present investigations deal with the throughfall, stemflow and intercreption loss in Cedius deodara Loudon plantation (94.5% crown density) or about 35 years age at Shillaroo, Kolgarh Forest Division, Distt. Simla (Himachal Pradesh). Of the total rainfall (1850.1 mm) 2.9% (55.3 mm) stemflow, 71.8% (1328.5 mm) throughfall and 25.2% (466.2 mm) interception loss were recorded respectively by for the whole study period. The minimum interception loss (18.7%) was observed in the month of July, 1980 which had the maximum (370.2 mm) rainfall. The highest interception (69.1%) was recorded in the month of February, 1980. which had the lowest (7.0 mm) rainfall. Interception loss was decreased with the increasing amount of precipitation.- Comparative Account of Undergrowth under Eucalyptus and Sal in Three Different Localities of Doon Valley

One of the reasons for the important place of Populus ciliata in erosion control is tHat P. ciliata is one of the few species which can be successfully established from branch and stem cuttings. P. ciliata ischolar_mains easily in shallow soils where other tree species can not be established. Poplars are being used extensively for erosion control and (or the re-vegetation of eroded hilly areas in China, Japan, U.S.A. and New Zealand. P. ciliata has reasonably fast growth rate and strong spreading ischolar_main system. Plants Grown from cuttings produce and abundance of strong, thick lateral ischolar_mains with little taper.- Groundwater Regime under Blue-gum at Osamund Nilgiris-initial Observations

Groundwater table fluctuations occurring under Eucalyptus globulus plantation has been measured to study the possibility of depletion of groundwater by Eucalyptus plantations. A series of piezometric holes were driven along a hill up with Eucalyptus globulus (Blue-gum) and a part covered with grassland and Shola at Osamund, Wenlockdowns reserved forest in the Nilgiris. The sub-soil water levels were monitored once daily. The depth of groundwater (December, 1979) varied between 15m in well in the low-laying area to 4.5m in well at the top of the slope whereas the corresponding figures (March, 1980) were 2.19m for well in low-lying areas and 6.2m for well at the top of the slope These groundwater table levels are much below the general ischolar_maining zone 2m of Eucalyptus except in the well in low-lying areas. This indicates that Eucalyptus gobulus does not tap groundwater table during December to March.- Vegetation Characteristics and their Effect on Runoff and Peak Rates from Small Watersheds

Two small brush wood watersheds W1F (1.45 ha) and W2F (.87 ha) were calibrated between 1961-68 and W1F was clearfelled and planted up with two species of Eucalyptus in 1969. Analyis of precalibration data 1961-68 indicated that W2F gave 18% less runoff & 63% lower peak rates as compared to W1F. Data analysis for the post treatment period 1969-74 indicated that W1F now gives 28% less runoff and 73% lower peak rates as compared to W2F. In order to find out the causes for this reduction, the vegetation in the two watersheds was surveyed and it was found out that W1F has 21 % more ground cover, 24% more trees, 39% more leaf litter, 68% more above ground and 11 % more under ground phytomass.- Land Treatment Measures and Flood Control
