[ANDRENA FLAVIPES; APPLE FLOWERS; PATH ANALYSIS; POLLINATION; WEATHER FACTORS]

The flight activity of Andrena flavipes Panzer (Hymenoptera : Andrenidae) pollinating apple flowers was related to some weather factors. The flight activity correlated positively with ambient temperature, light intensity, solar radiation, nectar-sugar concentration, soil temperature and negatively with relative humidity. Path coefficient analysis revealed whether the relationship expressed was direct or indirect. Of the six factors studied, the direct effect of ambient temperature, light intensity, solar radiation, soil temperature were positive and that of relative humidity negative. The direct effect of nectar-sugar concentration was positive and negligible.

[GLOBAL ECONOMY; HOUSEHOLD; HUSHE VALLEY; LIVESTOCK]

In a Karakorum-Himalaya valley, women go to high pastures with the livestock. They possess detailed knowledge, wisdom, and skills relating to their environment. They know how to manage the resources of animals and plants which they process for subsistence, sale, and barter. They also make trips down to the village: tending their crops and caring for their household. It appears that small children, young women, and grandparents inhabit one world, while the younger men and boys live in another. This is because the men of this valley are turning to the outside world for more lucrative opportunities, abandoning their share of subsistence work. They migrate to the plains for work, or find position as porters with visiting mountaineering expeditions. This has produced a sad state of affairs for people who still believe in family values rather than individual rights, and for whom arranged marriage is an economic alliance between clans. It creates a situation in which the husband depends on his wife for sustenance, while regarding her as `backward' and `inferior'. This is the problem of women: their subservient position and forced inclusion into the capitalist system of labor-first by their own men due to the patriarchal division of labor, which turns partners and co-workers into master and servant; then by the male elite of the village, who maintain and confirm this division; then by bureaucrats and corporate power-holders of the global market economy into which the women are inserted, without their knowledge, consent, or control.

Bhardwaj, S.P. and Sindhwal, N.S. 1998. Zero tillage and weed mulch for erosion control of sloping farm land in Doon valley. Indian J.Soil Cons., 26(2): 81-85. Central Soil and Water Conservation Research and Training Institute, Dehradun 248195, India. [DOON VALLEY; EROSION; MULCH; RUNOFF; SOIL AND NUTRIENT LOSS; ZERO TILLAGE]

Erosion is a serious problem in open tilled maize grown on slopes under high rainfall area of Doon Valley. To minimize erosion hazards, reduce cost of cultivation and increase the crop productivity an experiment was conducted on field size runoff plots at 4 per cent slope. Ground flora (grass and weeds) are effective in controlling soil erosion. Utilization of this advantage was attempted in the form of space management, allowing a strip of ground flora to grow, which was later cut and spread as mulch. This mulch (4.5-5.0 t ha-1) added 75 kg N, 17 kg P and 144 kg K to the soil. Mulch resulted significant increase in infiltration and soil moisture. The moisture thus conserved was quite effective in ensuring good germination and higher yield of wheat in rainfed areas. Zero tillage + weed mulch, normal tillage + weed mulch, zero tillage, contour cultivation and cultivated fallow treatment gave runoff : 22,31,42,51 and 52 per cent of rainfall, and 3,7,12,18 and 50 t ha-1 soil loss, respectively. Mulch also reduced and delayed the peaks of runoff. Slightly lower yield of maize in mulch plots was compensated by saving in weeding, improvement in soil moisture, fertility and increase in wheat yield.

To study the mycological wealth of Kumaun Himalayas, extensive surveys were conducted. The common edible, poisonous, ectomycorrhizal, fungicolous, rare, wood-decaying fungi and their commercial uses are discussed. In-situ and Ex-situ conservation of fungi for fungal diversity has also been suggested.

Immature embryos of Vanda coerulea were inoculated in both liquid and semi solid VW media (Vacin and Went, 1949), supplemented with vitamins and growth regulators like 1-Naphthalene aceticacid (NAA), 6-Benzyl amino purine (BAP), 6-Furfuryl amino purine, and Kinetin (KN). The semi-solid VW medium was enriched with 20% coconut water (CW). Germination of embryos occurred in both liquid and semi-solid media. However, higher percentage of, and faster rate of, germination were observed in VW liquid medium as compared to that in VW semi-solid medium. The differentiation of the protocorms into seedlings varied with the concentration and combination of growth regulators in VW semi-solid medium, enriched with 15% coconut water.

Biotechnology Laboratory, College of Agriculture, Central Agricultural University, Imphal 795004, India. [CLONAL PROPAGATION; DENDROBIUM HYBRIDS; SHOOT-TIP]

Shoot-tips and axillary buds from young shoots of six Dendrobium hybrids viz. Dendrobium Kasem Gold x D. Thed Takiguchi, D. Sonia No. 28, D. New Sahin Red, D. Ekapol Panda No.1, D. Sakura Pink and D. Banyad Pink were cultured in VW (Vacin and Went, 1949) and MS (Murashige and Skoog, 1962) media supplemented with Naphthalene acetic acid (0.1 mgl-1) and 6 Benzylaminopurine (1.0-2.0mgl-1). Multiple shoots were induced in VW medium modified with addition of thiamine - HCl (1.0 mgl-1), pyridoxine -HCl (1.0 mgl-1), nicotinic acid (1.0 mgl-1), adenine sulphate (100 mgl-1), myo-inositol (100 mgl-1), NAA (0.1 mgl-1), and BAP (3.0-4.0 mgl-1). Shoots were multiplied by cutting the mass of multiple shoots and subculturing in the same medium, thereby increasing the number of shoots.

The present paper deals with ethnomedicinal uses of 15 species of pteridophytic group of plants which is considered least known and economically less important group of plants in the plant kingdom. Various folklore receipes being used throughout India by the different group of people have been given.

Dhyani, S.K. and Tripathi, R.S. 1999. Tree growth and crop yield under agrisilvicultural practices in north-east India. Agroforestry Systems, 44: 1-12. ICAR Research Complex for North Eastern Hills Region, Umiam (Barapani), Meghalaya, India; Present Address: Central Soil & Water Conservation Research and Training Institute, 218-Kaulagarh Road, Dehradun 248195, U.P., India. [ALNUS; CHERRY; INTERCROPS; MANDARIN; SLOPING LANDS]

Tree growth, survival and crop yield under agrisilvicultural practices were analyzed over a seven-year period in a split plot experiment on acid alfisol under rainfed conditions at ICAR Research Farm, Barapani (Meghalaya), India. Three indigenous species including a fruit plant, and one introduced tree species formed the main plot treatments and three crop sequences were the sub-plot. The tree species were mandarin (Citrus reticulata), alder (Alnus nepalensis), cherry (Prunus cerasoides) and albizia (Paraserianthes falcataria), and the crop sequences were (a) soybean (Glycine max)-linseed (Linum usitatissimum) for three years, then groundnut (Arachis hypogea)-mustard (Brassica campestris) for three years followed by soybean-linseed in the seventh year, (b) groundnut-mustard for three years, then soybean-linseed for three years and groundnut-mustard in the seventh year, and (c) sole trees (`tree only'). A positive effect of intercropping on height and diameter growth, crown width and timber volume was observed in alder, albizia and cherry but no appreciable differences for these parameters were observed in mandarin between the two situations. Alder and albizia attained maximum growth and woody biomass followed by cherry and the minimum growth was recorded by mandarin. The better growth and timber volume in the `tree+crop' situation was mainly due to the application of fertilizers and weeding. Crop yield reduction was observed with alder, mandarin and cherry and as the distance from tree increased, yield also improved. However, in albizia the proximity of tree did not reduce crop yield. The implications of the results are discussed in the context of the suitability of the species in this region and their usefulness in agroforestry systems.

Pant Institute of Himalayan Environment and Development, Kosi-Katarmal, Almora 263643, India. [CROP DIVERSITY; DEMOGRAPHIC PROFILE; ECOLOGICAL DIVERSITY]

The Indian Central Himalaya has been receiving large amounts of development assistance, largely as a response to create infrastructural facilities for enhancing its production and better living. This paper suggests to understand how the present developmental initiatives have marginalised the Himalayan diversities, and has encouraged a narrowing of the economic, cultural and ecological characteristics of the region. Thus, has brought the society at the cross roads of unsustainability.

Garbyal, S.S. 1999. `Jhuming' (Shifting cultivation) in Mizoram (India) and new land use policy - How far it has succeeded in containing this primitive agriculture practice. Indian Forester, 125(2): 137-148. Director, Forest Education, New Forest, Dehradun, India. [LAND USE POLICY; MIZORAM; RURAL DEVELOPMENT; TRADE]

Shifting cultivation that is known as `jhuming' in Mizoram, is an integral part of the socio-cultural life of Mizos. With increase in population the jhuming cycle has shortened considerably and the productivity of land has fallen with devastating impact on the environment. The Govt. of Mizoram in 1984 launched a programme called New Land Use Policy (NLUP) with an objective to put an end to the practice of jhuming by providing alternative land based permanent occupation and stable income to the families practicing jhuming (jhumias) in rural areas thereby raising their standard of living. Assistance is provided for various trades or occupation for a period of three years. The programme is operated on yearly basis. In addition to the main trade, assistance is also provided for subsidiary trades so that the beneficiary earns income throughout the year. It is, however, found that the NLUP have not had any impact on jhuming as most of the beneficiaries are continuing jhuming even after receiving assistance under NLUP. Programme has also failed to bring out any perceptible improvement in the economic condition of the villagers. There has not been any significant change in the quality of life of the beneficiaries. There is a need to bring out changes in the attitudes towards jhuming. The programme needs restructuring. The beneficiaries, village councils and YMA need to be involved at all levels, proper marketing facilities for the products are required to be provided, utmost care is required while selecting the beneficiaries, the resources of various participating departments are required to be pooled in and effective monitoring and evaluation and evaluation system needs to be put in place.

Agriculture Extension and Rural Development Department, The University of Reading, Reading, UK; Nepal Agroforestry Foundation, Kathmandu, Nepal. [AGROFORESTRY; GENDER DIVISION; LIVELIHOOD; LIVESTOCK MANAGEMENT]

Trees, crops, and livestock are integral parts of the complex farming systems on Nepalese hillsides. Any strategy for soil fertility improvement will take account of the interactions between these components, both on private farmland and common property and in public access forest and grazing areas. This requires a less restricted definition of the slope of agro-forestry than has often been applied previously. Agro-forestry can contribute to soil fertility improvement through increasing the quality and quantity of fodder and hence livestock manure, providing biomass for composting and slowing the loss of nutrients through runoff. Socioeconomic contextual factors that influence the introduction of agro-forestry innovations include the distribution and fragmentation of landholding, the relative importance of agriculture in household livelihoods, and the gender division of labor and management responsibilities within households. Studies of socioeconomic patterns within and between rural communities, can enable researchers to better focus their efforts. Examples from Nepal are presented and their implications for research design, method, and process, and for dissemination are explored.

[COMMUNITY-BASED CONSERVATION; CONSERVATION AREAS; NEPAL; PROTECTED AREA]

The modern era of wildlife and protected area conservation in Nepal began in 1973 with the passage of comprehensive legislation, and has evolved very quickly as new priorities and problems have emerged. Here we explore the legal and managerial development of conservation areas, a recently-defined category of protected area designed to promote conservation through local-level participation and development. A review of the Conservation Area Management Regulations of 1996 shows that there are several potential problems inherent in this designation. As written, the regulations move power from the government to organizations under governmental contract. Thus, management authority largely remains top-down from the standpoint of local users. Ws also question how well the designation will protect some sensitive wildlife species, since organizations do not have law enforcement authority under Nepalese legislation. Despite these concerns, there have been several successful conservation area programmes in existence in Nepal since the 1980s and most of the issues addressed are surmountable with the current regulations, providing that several criteria are met. We propose the His Majesty's Government and organizations under contract develop more definitive methods of disbursing funds for local-level projects, and institute social impact assessments. In addition, more attention must be paid to wildlife law enforcement; independent assessment of important wild population and unique habitats are needed. Finally, we discuss some broader issues that should be better addressed in Nepal and elsewhere, including cross-sectoral coordination within the government.

A study was conducted in Langha Forest Range of Mussoorie Division under 15 years old plantations of Pinus roxburghii, Tectona grandis, Dalbergia sissoo, Eucalyptus, Acacia catechu along with natural Shorea robusta forest and barren land to find out the status of soil organic matter. This study was conducted before and after monsoon to investigate the changes in SOM due to change of seasons. Before monsoon it was observed that SOM content was higher under natural Shorea robusta followed by Dalbergia sissoo, Eucalyptus, Tectona grandis, Acacia catechu and Pinus roxburghii plantations and least under barren land and after monsoon it was higher under Eucalyptus only in top (0-10 cm) layer but over all higher under the soils of natural Shorea robusta followed by Eucalyptus, Dalbergia sissoo, Pinus roxburghii, Acacia catechu, Tectona grandis and least under barren land. In general SOM was observed higher in post-monsoon in comparison to pre-monsoon period.

Forest Soils and Land Reclamation Division, Forest Research Institute, Dehradun, India. [CUMULATIVE RAINFALL; EUCALYPTUS; REGRESSION EQUATION; TECTONA GRANDIS]

Gradual accretion of soil moisture in different depths with the progression of rainfall under Tectona grandis and Eucalyptus plantation at Langha range of Mussoorie Forest Division was studied. When cumulative rainfall rises upto 148.4mm, water percolates only upto 75 cm depth under both plantation. At CRF 815.2mm entire profile gets charged and no further increase in soil moisture was observed at 1421.1 m CRF, especially under Tectona grandis. The moisture accretion, in general, was higher in the soils supporting Eucalyptus in comparison to those under teak plantation and, in particular in the lower depths at the above CRF of 815.2 mm. It was observed that during dry months soil moisture has positive relationship with depth.

Resource-use decisions made by households and local communities in pursuit of today's survival and livelihood security are influenced by the policies, institutions, and technologies that impact on their lives. Such decisions are the main determinants of links between poverty elimination, improved land care, and sustainable rural livelihoods. In the long term such goals can be compatible but in the short term the need for increased yield with increasing populations is likely to undermine sustainable natural resource management. Increasing analysis and understanding of poverty, its measurement, and identification of the processes that create poverty, as well as improved land care are key to creating sustainable livelihoods. Hillside and mountainous areas are particularly vulnerable to poverty due to their inaccessibility, fragility, marginality, and diversity. Although many of the world hot spots for land degradation are found in hillside areas, there are also many bright spots where improvements in natural resource management are resulting in increased incomes. Poverty culmination will require revival of the community stake in the natural resource base, restoring local control over local resources, and use of local perspectives and traditional knowledge systems in development activities. New policies, institutions, and technologies will need to reflect these principles.

Indian Journal of Forestry, 22(2): 95-100. Forest Pathology Division, Forest Research Institute, Dehradun, U.P., India. [ECTOMYCORRHIZAL; MYCORRHIZAL FUNGI; PINUS ROXBURGHII]

A quantitative and qualitative assessment of mycorrhiza development was made in uninoculated seedling stock of Pinus roxburghii raised from seeds of twenty provenances. Significant differences were observed in mycorrhiza formation by indigenous mycorrhizal fungi representing seven distinct groups of provenances. Kuthnoor, Dharashu, Deha and Dibkhan provenances form a separate group which shows significantly higher values for short root formation, mycorrhizal roots and per cent mycorrhizal roots per plant in relation to group of Dharmshala, Bhader Kali, Mashobra, Neri Nissoo and Chabal Ki Dhar provenances which show significantly lower values for all the three parameters. Six forms of mycorrhizae were observed out of which one, light to dark brown, smooth form was predominant in association with thirteen provenances followed by smooth, brown, loose hyphal and yellow to sepia in groups of seven, six and five provenances, whereas others were restricted to one and two provenances.

The long-term conditional probabilities of occurrence of great earthquakes along the Himalaya plate boundary seismic zone have been estimated. The chance of occurrence of at least one great earthquake along this seismic zone in a period of 100 years (beginning with the year 1999) is estimated to be about 0.89. The 100-year probability of such an earthquake occurring in the Kashmir seismic gap is about 0.27, in the central seismic gap is about 0.52 and in the Assam gap is about 0.21. The 25-year probabilities of their occurrence are 0.07, 0.17, and 0.05 for the Kashmir, the central and the Assam seismic gaps, respectively. These probabilities will serve in the assessment of the seismic hazard in the Himalaya and the adjoining Ganga plains.

Kishtwaria, J. 1999. Time expenditure pattern of Gaddi tribal women of Himachal Pradesh. Journal of Human Ecology, 10(4): 255-257. College of Home Science, HPKV, Palampur 176062, H.P., India. [GADDI; TIME EXPENDITURE PATTERN; TRIBAL WOMEN; UNEMPLOYED AND EMPLOYED]

Tribal women spent a large proportion of their time in carrying out household work, animal care, agricultural and allied tasks. However, gainfully employed respondents spent significantly less time while performing all these tasks than non-employed respondents. Thus, there is a scope to improve time use pattern of non-employed respondents for effective implementation on development policies and programmes in the free time available to them.

[ACCUMULATION ZONE; HUMAN SETTLEMENT; RADIOMETRIC TECHNIQUES; SEDIMENTATION]

An attempt has been made to predict the life of Lake Nainital, a natural lake located in the Kumaun Himalaya with a fairly large human settlement around it. Sediment accumulation rates estimated by dating the lake sediment cores employing 210Pb and 137Cs dating techniques have been used for the purpose. The sediment accumulation rates estimated by radioisotope techniques are comparable to the rates obtained by the sediment balance method using suspended sediment data. The estimated useful life of the lake is about 2,200 years, which is much higher than the results obtained by earlier investigators who used short term bathymetric data. In the present study, long-term (46 years) annual lake sounding data have also been analysed. Large bi-directional variations in the annual bathymetry imply that major errors are associated with the lake sounding data that led to the under-estimation of the life span of Lake Nainital by earlier investigators.

Pant Institute of Himalayan Environment and Development, Kosi-Katarmal, Almora 263 643, India. [COST ESTIMATE; LAND-USE PATTERN; LANDSLIDE]

Large scale landsliding of inhabited tracts in the Kumaun Himalaya have wrecked havoc to the natural environment and economy of the region. The village agricultural and pasture lands, communication routes, human and animal population and other structures are all severely affected by landslides, underlining their significance for the economy of the region. In 1998, one such landslide in the Malpa village of Kumaun region turned out to be one of the major disasters of recent times, taking a heavy toll of human life (207). Other losses includes animals (69), agricultural land (0.408 ha), huts (5), houses (5), and wooden bridge. According to the tehsil records, the total loss in monetary terms has been assessed at Rs. 38,51,400/-, but this assessment is highly underestimated as it ignores private losses. An attempt is, therefore, made in this paper to make a detailed analysis of all damages, both public and private to estimate the total cost of landslide damages. This estimated to be Rs. 56,94,203/- which is about 1.5 times the official estimate. The total cost of human life in terms of compensation decided by the government, comes out to be over Rs. 2 crores. The present study also highlights different aspects of landslide costs which must be included calculating the cost of damage.

[ELECTRICAL CODUCTIVITY; LAND-USE PATTERN; pH MEASURE; SURFACE WATER]

Sound water resource management is the key to some of water related problems in hills which requires both quantitative and qualitative assessment of water sources. The present study is focused on qualitative aspect of domestic water supply sources in Almora district of Kumaun Himalaya. Surface water is main source for domestic water supply schemes in the region which is generally influenced by the changes in land use pattern. The chemistry of surface water in north and south zones of the district having different land use patterns is discussed and then results are compared with water quality standards. Surface water in south Almora is better in quality than north in terms of dissolved ions. Some influence of agricultural activities is noticed in the form of high nitrate levels in north zone. Most of the water samples contain flourides possibly from the bed rocks. However, in both the cases water has been found suitable for domestic water supply.

The relation of surface lowering, net balance and flow dynamics reflects that vertical component of ice flow is downward in and around the equilibrium line while it is upward in the lower part (ablation zone) of Chhota Shigri Glacier. The submergence velocity in accumulation area is higher than the rise of surface and emergence velocity is lower than that of negative net balance. The basal sliding velocity is responsible for the movement of the glacier. The over-extension of the glacier at average snout position is one of the factors in controlling the temperature variation of the main Chandra river valley.

The highest values for leaf area increment leaf dry weight increment, leaf growth rate, shoot height growth and specific leaf area were recorded, respectively in April, November, April, July and March. Population structure indicated inverted pyramidal shape across all the sampling dates. Of the total natality 92% occurred between April to August. However, the maximum mortality was recorded between August to December.

The present communication deals with diversity, ecology and distribution of Indian Lactuceae (Asteraceae) which is represented by 10 genera namely Lactuca L., Prenanthes L., Launaea Cass., Sonchus L., Reichardia Roth, Cicerbita Wallr., Ixeris, Cass., Chondrilla L., Dubyaea DC and Youngia Cass., with 80 taxa in India. Among these 9 genera and 51 taxa are from the Western Himalaya, 7 genera and 31 taxa from Eastern Himalaya, 5 genera and 12 taxa from Western and Eastern Ghats and 6 genera and 15 taxa from Gangetic plains, Rajasthan and other parts of the country. The Lactuceae exhibit wide range of variations in its ecological habitats from sea coast to 5000 m in elevations and exhibit enormous diversity both intraspecifically and interspecifically. The Himalayas are shown to be major centre for Lactuceae diversity and distribution followed by Western Ghats and Gangetic plains. At generic level Lactuca exhibits maximum diversity with 25 species followed by Youngia and Cicerbita, all three are predominantly Himalayan. The genus Dubyaea is endemic to Sino-Himalayan region with 9 species, while 6 of its 9 species are highly localized in this region. The maximum diversity of Lactuceae in the Himalaya is due to a variety of climatic conditions and altitudes which in turn has resulted in diverse habitats. The Lactuceae inhabit every conceivable habitats and reveals a great amount of variation in the populations of different species. The distribution analysis of Lactuceae reveals that its members are chiefly distributed in the Himalaya and poorly represented in Western Ghats, Eastern Ghats and Gangetic plains.

Department of Geography, University of Durham, Science Site, South Rd., Durham, DH1 3LE, UK. [BACKWARD CASTES; ECONOMIC GROWTH; HIMALAYAN STATE; POLITICAL REPRESENTATION; REGIONALISM]

In April 1998 the newly elected Government of India announced that it would oversee the creation of four new states within the Federal Union of India. One of these regions currently forms the Himalayan part of Uttar Pradesh, and will be known as Uttaranchal. The reason given for this decision is that the formation of a smaller, separate state will encourage greater administrative efficiency and political accountability in this `backward' mountain region. This proposal was first officially accepted by the Government of Uttar Pradesh in 1991, and ever since then development planners, academics, economics, and civil servants have discussed the economic and political viability of the proposal. However, much less is heard about what ordinary villagers and townpeople of this hill region think about these issues, despite the fact that their recent mass protest played a vital part in persuading the Central Government to accept the proposal for a separate hill state. This paper explores some of the perceptions of ordinary hill men and women on the subjects of regionalism, politics, and development.

Niche width, b-diversity, equatibility and PxF index for important herbs and graminoids of an alpine grazingland in Panwali Kantha (Garhwal, Western Himalaya) at different aspects and altitudes have been discussed. Phleum alpinum among the graminoides exhibited maximum niche width the Bupleurum lanceolatum and Taraxacum officinale showed maximum niche location. Higher b-diversity and equatibility values at stand CDC II indicated rapid change in species composition and community heterogeneity according to species adaptability and growth requirements. The continuum index values showed better impact of environmental gradients on the vegetation.

Plant genetic resources were studied in Central Himalaya, which constitutes Garhwal and Kumaun regions of Uttar Pradesh by National Bureau of Plant Genetic Resources (NBPGR), Head Quarter, New Delhi and its regional station-Bhowali in October, 1996. In total, 107 accessions, mainly medicinal and aromatic plants (M. & AP.) from valley areas (lower altitude up to 1500 m a.s.l.), M. & AP. from Higher altitudes (alpine and meadows) up to 4000 m a.s.l., lesser known plants, wild relatives, wild economically useful plants and paddy germplasm were collected. It belongs to 67 species, 54 genera, many of the 63 accessions being dominant of the M. & AP. In case of paddy, some of the unexplored and promising areas of Central Himalayan villages, i.e., Tapovan, near Rishikesh (Distt.-Tehri) and Chakrata (Distt.- Dehradun), landraces and local/primitive cultivars are still common. The efforts are continued to maintain the collected plant material by ex-situ and in-situ conservation in NBPGR.

The precambrian Amritpur Granite Series (AGS) in the Kumaun Lesser Himalaya is a composite body of three distinct types, viz, Porphyritic Amritpur Granite (PAG), Equigranular Amritpur Granite (EAG) Amritpur Porphyry (AP) and extends for a length of 60 km. Signature of Precambrian, pre-Himalayan contact metamorphism in addition to the Himalayan regional metamorphism (greenschist to lower amphibolite facies) and subsequent retrograde metamorphism are observed in the AGS. The authors have provided definite evidence for a contact aureole zone around AGS in the east of Hairakhan, NE of Durgapipal and Chandadevi and reported the xenoliths of PAG and EAG types in AP at Jamrani indicating a younger age of AP.

Department of Forestry, Kumaun University, Nainital 263002, India. [CROWN COVER; DIVERSITY INDEX; OAK FOREST; RELATIVE DENSITY]

The tree layer analysis was carried out in a high altitude Chir-pine mixed Oak forest situated between 1800-2100 m elevation. The low density of seedling and saplings in almost all the species in this forest indicates poor regeneration pattern. Quercus leucotrichophora due to serve lopping pressure fails to produce seeds. The most characteristic feature of the forest is the dominance of pine (Pinus roxburghii) and Rhododendron arboreum over Banj-oak (Q. leucotrichophora in the Oak zone. Repeated fires and other biotic factors are making the area poor, both in nutrients and top soil which will eventually result in the desertification of the Himalaya in the long run.

The present study deals with the status and patterns of agroforestry practices in Tarai region of Kumaun. The study was made in three villages (Narayanpur, Ganeshpur and Gangapur) of Udham Singh Nagar District lying between 28.9oN latitude and 79.4oE longitude. Among the trees planted Poplar is most preferred species. Study of agroforestry patterns reveals that bund planting is predominant in the areas following with wayside and field plantations. In these villages 100% farmers have adopted agroforestry practices thereby reducing pressure on the surrounding natural forests.

In vitro studies were conducted to assess the regeneration response of stem explants (each bearing a bud) procured from shoots emerging from Dendrobium cv. Sonia pseudobulbs using four different culture media. Both Vacin and Went (VW, 1949) and Knudson C (KC, 1946) media favoured formation of protocorm like bodies (PLBs) and subsequent development of plantlets. KC medium supplemented with BAP (1.5 mgl-1), NAA (0.4mgl-1) and paelobutrazol (Imgl-1) was found to be best for further multiplication of PLBs. All the media favoured rooting when supplemented with IBA (Imgl-1) or NAA (1.8 mgl-1) and paelobutrazol (0.5 mgl-1). Hardening medium containing bark pieces, brick pieces, moss, and charcoal pieces (1:1:1:1) proved suitable for the establishment of in vitro rooted plantlets.

This paper highlights the scarcity of arable cropland in the hills and mountains of the Himalayan region. This is one of the factors leading to food insecurity and poverty. Technological interventions were applied in some areas to increase the amount of land available by making productive use of marginal areas. This has been supported by strong political commitment which facilitates a favorable policy environment for investment in technological research, enterprise, and infrastructure development. These experiences indicate a new thinking which advocates research into 'niche based' sustainable production systems on marginal lands as part of the solution to cropland scarcity. Better management of marginal land and improved livelihoods may result.

Vegetational composition and diversity were studied were studied in the alpine grassland Panwalikantha (3963m) in Garhwal Himalayas, which is intensively grazed in the summer months. Seven distinct plant communities, were identified. Importance value index (IVI), Sorenson's similarity index, Shannon's diversity index (H), Concentration of dominance (Cd) were calculated and cluster and analysis of sampling units was carried out. Species richness was highest (42) in the moderately grazed plot and least in the intensively grazed plot. Diversity (H) was also the highest in the moderately grazed plot (3.6) and least in the grazed site (1.58). Under continued grazing Danthonia cachmeriana and Saxifraga androsacea was replaced with Carex nubigena and Trachydium roylei. Results indicate that intensity of grazing directly affects species occurrence and diversity. Moderate grazing increased and continued protection decreased species diversity, while unchecked grazing led to the disappearance of several species, and their gradual replacement with unpalatable herbs.

[CONSERVATION; FUEL-WOOD; OAK-RHODODENDRON; SHRUB DENSITY]

Studies on the plant species diversity and community structure were carried in the outer fringes (1550m - 1900m) of Kedarnath Wildlife Sanctuary, Western Himalaya. Five sites were selected along the gradient of human use which represented various stages of Oak-Rhododendron Quercus leucotrichophora - Rhododendron arboreum community. The tree density varied significantly among the sites (ANOVA p<0.001) but there was no significant variation in the shrub density. The diversity of tree and shrub species have been compared separately at various sites using Shannon-Wiener index. The number of woody species was highest in the moderately disturbed site where as lowest in the Oak forest protected and artificially regenerated by the villagers. Moderately disturbed site showed best regeneration of ban Oak. However, maximum tree species diversity, structural (and possibly functional diversity) are exhibited by the old growth forest. Indicators of different seral stages have been identified and conservation implications discussed.

The study reveals the structure of chir pine community along two aspects and four elevational zones in Garhwal Himalaya. The findings indicated that chir pine prefers sunny slopes with xeric conditions and is dominated in the drier south facing slopes. Therefore it should be recommended for the naked and drier slopes of Garhwal Himalaya as a pioneer species for vegetation cover.

[ALLOMETRIC EQUATIONS; BIOMASS PRODUCTION; CURRENT ANNUAL INCREMENT; MEAN ANNUAL INCREMENT; ROBINIA PSEUDOACACIA]

The study deals with the biomass production and allocation in young (6 months to 4 years old) Robinia pseudoacacia L. plants. The height, basal girth and dry weight of each component of the plant increased with age. Satisfactory allometric equations relating to biomass of different components with basal girth (Bg) and squared basal diameter x height (bd2h) were developed. The intercomponent biomass relationships were also highly significant and the resulting allometric equations carried smaller error than the equation using Bg as the independent variable. The mean annual increment has increased with age and did not equal current annual increment, indicating the individuals have not attained maturity. Number of root nodules per tree were significantly related to corresponding tree biomass and age.

The investigation was carried out at CSWCRTI, Research Farm, Selakui, Dehradun to see the productivity of groundstorey crops with different tree species. The cropping sequence (jowar-torai) was tested with three plantation i.e. Eucalyptus hybrid, Bombax ceiba and mixed plantations (natural) of Cassia fistula, Bombax ceiba, Acacia catechu, Lannea coromandalica and Dalbergia sissoo. It was observed that about 14.89, 12.79 and 12.14 t/ha green fodder yield of jowar can be obtained with Bombax ceiba, Eucalyptus hybrid and mixed plantations, respectively. The trend was same with toria and seed yield recorded were 3.68, 2.78 and 2.38 q/ha under Bombax ceiba, Eucalyptus hybrid and mixed plantations, respectively. The yield of both the crops increases with increasing distance from the tree trunk, however the direction did not influence the yield of groundstorey crops.

Growing demand of Poplar wood for manufacture of fruit boxes, plyboard, match sticks due to its fast growth and colourless wood have led to extensive plantation of this species. This has resulted in severe outbreak of a number of diseases. Alternaria alternata is one of the most destructive pathogens of Populus species in nurseries resulting in premature defoliation. During 1997, an experiment was conducted to assess 232 different clones/hybrids of P. ciliata and P. deltoides against A. alternata. Out of 29 clones and 75 hybrids of P. ciliata,3 clones and 22 hybrids remained free from the disease. In 11 clones and 2 hybrids of P. ciliata, disease reaction varied from resistant to moderately resistant. Out of 73 clones and 7 hybrids of P. deltoides, 64 clones and 7 hybrids remained free from the disease. All the 46 families of P. deltoides screened were found free from the disease.

Investigations were carried out at Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.), India, to find out suitable storage method(s). The freshly collected acorns were put in storage at 5±1oC, 10±1oC and room temperature in polybags, canvas bags and tin containers laid out in Split Plot Design with three replications and storage longevity was determined by subjecting the acorns to germinability studies. The acorns stored at 5±1oC in polybags was proved to be the suitable method for better longevity of acorns maintaining a maximum of 90 per cent germination for consecutive nine months and thereafter declined slightly maintaining 51.16 per cent germination after fifteen months of storage as compared to all other interactions. However, the seed stored at room temperature in tin containers proved to be least effective and lost its viability after three months of storage.

Orchidaceae, the second largest family of flowering plants in the world, show remarkable diversity in this smallest Himalayan state. Out of 184 genera and about 1200 species reported from India, 115 genera and about 496 species are represented in this region. The present paper elucidates correct nomenclature, phenological data, range of distribution and phytogeographical affinities of orchid species, reported from Sikkim so far. Diversity of orchids in different altitudinal zones has also been discussed. Bulbophyllum, Dendrobium, Eria, Liparis and Oberonia are the dominent genera in Sikkim whereas 88 genera like Acrachaene, Amitostrgma, Androcorys, Anthyogonium, Arundina, Bletilla, Neottia are represented by a single species each. Interestingly, 37 species are endemic to this state and there are several species which exhibit wide transoceanic distribution. Overexploitation of a number of species for horticultural purpose and destruction of their natural habitats have contributed to the depletion of biodiversity of many species, several species of orchids are threatened with extinction. Conservation strategy for such species has also been discussed.

Butterflies were collected for six years from New Forest campus which is a man-made habitat covering an area of 4.45 km2 and located at Dehradun in Northern India. The aim of the study was to know butterfly species composition of this artificial habitat in relation to the Western Himalayas and also the number of larval food plant species of butterflies supported by this habitat. A total of 148 species belonging to 10 families and sub-families were found in New Forest which was one-third of the total found in the region. Three species found were `rare' as listed in the Schedule II of the Indian Wildlife Protection Act (1972, amended 1989). Larval food plants for all the butterfly species were present in New Forest. The proportions all the butterfly species in the families found here were in constancy with the region and were more closely related to the Western Himalaya, as compared to the Central Himalaya or the entire Indian Sub-Continent. All these findings suggest that New Forest provides a refuge for a large number of butterfly species found in the region, depicting a point diversity.

Maximum callusing (74.60%) was obtained with 1000 ppm of IAA treatment, whereas highest rooting percentage (64.93%) was recorded in 2000 ppm IBA treated cuttings. Shoot length was observed highest (167.11 cm) with 2000 ppm IBA treatment and lowest in 3000 ppm NAA treated cutting. However, a non-significant difference was noticed among different auxin concentrations for root shoot ratio.

Botany Division, Central Drug Research Institute, Lucknow 226001. [DIVERSITY; LEAF-SHOOT; RHYNCHANTHUS LONGIFLORUS]

The North-eastern region of India has maximum diversity of Zingiberaceae in having 19 genera and about 90 species from among 22 genera and 180 species known from India. The present communication on the genus Rhynchanthus Hook f., is the outcome of our critical taxonomic studies initiated recently on this family. This genus is known in India by only its type species (viz. R. longiflorus Hook. f.) from the Mizoram after Fischer's report (1932) and is based on our collection after more than six decades, which represents to be the first one for Indian herbaria. The genus is characterised by a boat-shaped stamen, obsolete or minute labellum and absence of lateral staminodes. The study further reveals the interesting characters of the genus and its close affinity with Hedychieae rather than with the Alpinieae to which it is generally assigned. It is described here with illustration.

Central Soil and Water Conservation Research and Training Institute, Dehradun, India. [GENETIC VARIATION; GERMINATION; GREWIA OPTIVA; REGRESSION EQUATION]

Statistical computation on seed traits and germination of the provenances revealed the existence of genetic variability. The correlation between different pairs of characters were determined and observed highly significant. The multiple regression equation using step-down regression technique revealed that the seed length and 100-seed weight might be used as the predictors of germination in Grewia optiva.

During surveillance of nursery diseases a seedling disease causing collar rot in Azadirachta indica caused by Fusarium semitectum was recorded for the first time from Satyanarain nursery at Dehradun causing 3 to 66 per cent mortality in 2 to 3 months old seedlings. Pathogenicity of fungus was tested and effect of different fungicides was tested on the growth of the pathogen in vitro. Ziram and Bavistin were found most effective in checking the pathogen.

Net N-mineralization and nitrification rates were measured by in situ incubation of soil in a needle leaf forest in central Himalaya. The seasonal pattern for both nitrification and ammonification was similar. Rainy season conditions were more favourable for N-mineralization. The size of the available nitrogen pool ranged from 8-30 ug g-1 with maximum values in the dry period (summer season) and minimum values during the wet period (rainy season). The trend for N-mineralization rate was opposite to that of the size of the available N.

[ACTIVE GROWTH SEASON; ALBIZIA STIPULATA; LOPPING TIME; OUGENIA OOJEINENSIS]

Tree foliage is a nutrient-rich and important source of green fodder to sustain the live-stock during the lean winter period of a season in the low and mid hill regions of Indian Himalaya. Knowledge of the variations in mineral nutrient composition of the foliage during an active growth season helps in determining optimum lopping time to harvest nutrient-rich fodder. Changes in the nutrient concentrations of Albizia stipulata and Ougenia oojeinensis foliage during the annual growth season were studied to find out an optimum lopping time. Two dissimilar trends in variation of nutrients in foliage with the advancement of growth season were observed. These were: (1) depletion/dilution of N, P, K and S and (2) accumulation of Ca, Mg and Na. The depletion was more from October onwards, and accumulation reached to its maximum in November-December. Therefore, the period from October to December, preferably November, can be regarded as optimum lopping time for A. stipulata For O. oojeinensis the corresponding time could be September to November, preferably. Ougenia foliage contained higher concentration of N, P, Ca, Mg, and Na than that of Albizia.

Orchid laboratory, Botany Department, Punjab University, Chandigarh 160014, India. [EVERGREEN FOREST; ORCHID FLORA; SOIL PROFILE; SUBSTRATUM ANALYSIS]

The distribution pattern and substratum analysis of twenty ground growing species of orchids from Shimla hills was presently studied. The orchids were primarily found on north facing hills. On the basis of growth and distribution frequency of orchids, open grassy and/or gravely slopes; semi-shaded to shaded, humus-rich and moist forest floors; and disturbed situations along forest borders and road embankments were identified as orchid habitats. The orchids inhabiting open areas showed preference for lesser humidity, more light, and quick water drain-off whereas those inhabiting the shaded areas required humus-rich substratum and a regular supply of moisture, with less exposure to direct sunlight. The orchids in general, cohabited with a variety of vegetation; the shade-loving ones grew in association with ferns, whereas the light-loving ones grew with mosses, liverworts, and lichens. The soils in different localities varied in their texture as well as in their moisture and nutrient contents besides pH and conductivity. The adaptability of orchids to soils variously rich in carbon, nitrogen, phosphorous, and potassium suggested that these elements are important for their growth and development, and that the requirement is species specific.
