MORTALITY RATES]
The present paper deals with the early childhood mortality among the Khasi,
Garo and Mizo tribe of Shillong in respect of causes of death, mortality
rates and medical facilities. The study reveals that diarrhoea, respiratory
troubles, asphyxia and jaundice are the main factors causing child mortality
in these three populations. Infant and under five mortality both are found
to be very low among the Mizo than India's urban rate, whereas among the
Garo these rate are slightly higher but among the Khasi these rate are
considerably lower in comparison with India's urban population. When the
medical facilities availed by these communities are taken into consideration
it is found that the Mizo availed considerably more facilities than the
Khasi and Garo, and in turn, the Khasi availed more medical facilities
than the Garo.

The present study was undertaken to assess the regeneration pattern, tree
diversity and qualitative characters of forest in the Tarai-Bhabhar belt
of Kumaun Central Himalaya, India located between 29o25' to
29o40' N and 78o45' to 79o5' E longitude
and between an altitudinal transect of 200-800 m. The total tree density
varied from 4.3 trees/100m2 to 11.2 trees/100m2 and
the tree diversity from 0 to 2.18. Absence of young regeneration of all
the important dominant species showed the inability of these forests to
produce progenies due to repeated burning by the U.P. State Forest Department
and severe biotic pressure, by both wild and domestic animals.

A comparative cyto-morphological base study of ethnobotanical sacred plant
Acalypha
indica L is reported from Indo-Nepal Himalayan terai region from two
epicentres of different habitat and altitude (120 474 msl.) There was no
marked difference in characters, maintained same ethnographic use since
time immemorial by tribal community Tharu due to its ethnomedicinal and
non-plastic status. Apart from basic data, the study revealed that despite
non-flexible nature, the plant colonises naturally in diverse circumstances.
The paper highlights the specific under-shrub plant diversity and a hypothesis
of bio-diversity and tribal association.

SPATHIFLORUS; WATER USE EFFICIENCY]
An efficient protocol for in vitro propagation of Thamnocalamus spathiflorus
(Trin.) Munro, an evergreen temperate bamboo, through multiple shoot formation
from zygotic embryos excised from germinating seeds, as well as from nodal
explants taken from a 2-year-old plant has been developed. Multiple shoot
formation was standardized in both the cases on Murashige and Skoog (MS)
medium supplemented with 5.0 m M 6-benzylaminopurine
(BAP) and 1.0 m M indole-3-butyric acid (IBA).
Clumps of three to four microshoots when transferred to plant growth regulator-free
medium following 14 days initial culture on medium supplemented with 150.0
m
M IBA, resulted in 100% rooting with five to 12 roots per rooted plant.
Then, 18 months following the transfer of in vitro propagated plants into
earthen pots containing soil and growth under outdoor conditions, gas and
water vapour exchange rates were measured at different light levels (0,
100, 500, 1000, 1500, 2000 m mol-2 s-1),
and compared with seedlings of the same age. Light optima for photosynthesis
were recorded ~1000 m mol m-2s-1
in in vitro propagated plants as well as seedlings. Water use efficiency
increased with increase in the light intensity up to 1000 m
mol m-2 s-1 and then decreased subsequently at higher
light intensities. Stomatal conductance and transpiration also increased
with the increase in light intensity up to 2000 m
mol-2s-1. Intercellular CO2 concentration
(Ci)
and the ratio of intercellular CO2 concentration to ambient
CO2(Ci /Ca) decreased with
the increase in light intensity up to 500 m
mol-2s-1 and then reached nearly constant levels
at higher light intensities. The results show that in vitro propagated
and hardened plants of T. spathiflorus are morphologically as well
as functionally comparable to seed raised plants of the same age, within
the limits of this study.

Diversity
and distribution of endemic and exotic earthworms in natural and regenerating

REGENERATION]
A comparative analysis of earthworm communities was carried out in the
central Himalayas to understand the impact of deforestation and degradation
of natural forest sites. Earthworm communities were studied in the climax
forest, sub climax mixed forest, regenerating open grassland and 6 and
40 year-old pine forest sites with varying degree of disturbance at monthly
intervals over a period of 1 year. Eight species belonging to four families
were recorded from these sites, Lumbricidae (Bimostus parvus, Octolasion
tyrtaeum), Octochaetidae (Octochaetona beatrix), Megascolecidae
(Amynthas
corticis, Eutyphoeus festivus, E. nanianus, E. wawaltonii) and Moniligastridae
(Drawida
sp.). The loss of natural climax vegetation led to the loss of endemic
E.
nanianus, endemic E. festivus and E. waltoni and three
exotic species A. corticis, B. parvus and
O. beatrix sp.
and Drawida sp. appeared in the regenerating sites. Due to the process
of deforestation and degradation a general decline in the density of the
endemic species and the dominance by exotics were observed. The maximum
number of species were recorded in 40 year-old pine forest. The present
study emphasised the fact that in the central Himalayas the functional
guild (endogees-anecies) change under different vegetation type; organic
matter characteristics could be an important factor for this. Biological
invasion was also observed in the climax forest due to the presence of
exotic O. tyrtaeum. Except for A. corticis all other species
had significantly higher density during the rainy season. A. corticis
had maximum winter population in both 6 and 40 year-old pine forest. Population
size of earthworms were significantly correlated with soil moisture, temperature
and organic matter. Fire in the subclimax mixed forest caused significant
decline in the population density of earthworm species. The accidental
fire in the subclimax forest affected population recovery differently for
different species. Thus O. tyrtaeum and E. nanianus improved
significantly after 60 and 120 days after the fire.

Development is a process in which dissimilar communities and groups of
people react to new economic opportunities. India is a predominantly rural
country and rural development is national development. But conditions of
the poor is more severe in rural areas. The aim of the present study is
to analyse spatial inequality in Garhwal Himalaya which is part of the
Himalayas. Tehri Garhwal is the poorest district of Garhwal Himalaya. Such
inequalities are due to ignorance of socio-economic and physiographic diversity
of different regions, lack of employment opportunities in the hills and
the polikcy of protective discrimination.

(p<0.05)
up to four successive subculture cycles. Over 83% shoots rooted on one-fourth
strength Murashige and Skoog (MS) medium supplemented with 1.0 m
M a-naphthaleneacetic acid (NAA). Fifty percent
of plantlets (15 No.) successfully acclimatized in 90 g (w/v) soilrite
+ sand + soil (2:1:1) in the shed house. Preconditioning at different sucrose
concentrations prior to acclimatization showed no effect on percent survival
but improved plant quality.

An efficient method of micropropagation based on an increased percentage
survival of explants and reduced phenolinduced browing in wild strawberry
has been developed. Serial transfer of nodal explants was carried out at
24-,48- and 96-h intervals. Nodal segments cultured on Murashige and Skoog
medium supplemented with 6-benzyladenine (4.0 m
M) and a-naphthalene acetic acid (0.1 m
M) gave the best (94.4%) explant establishment and shoot number (22.3)
per explant. Of the cytokinins tested, 6-benzyladenine was found more effective
than kinetin and N6-(g ,g
dimethylallyamino) purine. Excised shoots rooted on half-strength agar-gelled
medium with 1.0 m M a-naphthalene
acetic acid. Rooted shoots with fully expanded leaves acclimatized successfully
and about 70% of plantlets survived ex vitro.

HIMALAYA; MEAN GERMINATION TIME; SEED GERMINATION]
The paper describes various experiments carried out to break the dormancy,
improve germination ability and reduce the mean germination time (MGT).
Germination ability of seeds from different sources (population) were compared
to determine the effect of source environment. However, results revealed
no significant variation in germination among sources. Compared to control,
most of the pretreatments improved percent germination. The imbibed seeds
prechilled at 4oC for 20 days showed best (48.6%) response.
Significant reduction of MGT and substantial improvement in germination
(MGT 28.6 d; Germination 42.1%) was, however, observed for 100 ppm GA3
(in scarified seeds) pretreatment. Considering practical feasibility and
cost effectiveness, the mechanical scarification at micropyle end (MGT-31.6
d; mean germination 40.0%) was recommended as one of the best options especially
for rural inhabitants. An attempt has been made to identify various attributes
contributing toward seed germination responses in Myrica esculenta.
The physical dormancy caused by an impermeable seed coat appears to be
the main reason of poor germination.

The present study investigate the germination requirements of the seeds
of Rumex hastatus with respect to temperature, light and substrate.
Both field and laboratory studies indicate that temperature 27-28oC,
light and soil condition are important factors governing germination of
seeds produced either in June or December. Unfavourable temperature regimes
prevent winter seeds from germinating for seven months but favourable temperature
enables summer seeds to germinate within a month after collection. Summer
seeds are at an advantage because seed viability declines with storage
time.

Dormancy and sprouting behaviour of six promising mulberry genotypes were
studied under sub-tropical agroclimate. Genotype S146(Morus
alba) exhibited the shortest dormancy period of 44 days; whereas, the
longest period of 72 days was recorded in Sujanpur (M. indica),
the local popular variety of this region. The leaf shedding was first noticed
in genotypes Chak Majra and Sujanpur, while delayed leaf fall was observed
in genotype Mandalay (M. indica). The genotypes S146
and Chak Majra were observed to sprout earlier than other genotypes.

Protocols for the micropropagation of two traditional medicinal plant Eclipta
alba (L.) and Eupatorium adenophorum (L.) from nodal segments
were developed. Proliferated microshoots of Eclipta alba and Eupatorium
adenophorum were obtained through axillary branching by culturing nodal
segments in modified MS medium and half strength of MS, respectively, with
minimal strength of nutritional support. Simultaneous rooting could also
be induced in the same medium. Regenerated rooted plantlets were successfully
acclimatized in soil where they grew normally without showing any morphological
variation.

Goiter prevalence of selected population in respect of age, sex and caste
was evaluated in the conventional iodine deficient Tripura of north east
India during post-salt iodization phase. The study was carried out on 10,801
school-children in the age group 6-15 years of both sexes from randomly
selected 22 representative localities. In selected localities, children
were clinically examined for goiter catagorising them in respect in respect
of ages, sexes and castes. Obtained results showed goiter was prevalent
at endemic level (more than 5%) in all study localities. With advancement
age the rate was found to increase up to the age of 11 years in both sexes.
However in boys a gradual decline in goiter rate was found and returned
to basal level by 15 years while in girls the rate of increase remained
steady up to 15 years. Female population was effected more than the male
in prevalence and severity. They were exposed under uniform system of iodine
supply and dietary goitrogens, however endemic goiter was mostly prevalent
in general castes, moderately among scheduled castes and minimum among
scheduled tribes. These variations might be due to non-uniform environmental
adaptability associated with different dietary practices.

The impact of aspect, altitude, slope and soil has been studied on the
moist temperate forest of Quercus leucotrichophora A. Campus in
Garhwal Himalaya. Four faces namely North-East, North-West, South-East
and South-West have been studied to understand the growth behaviour of
Q.
leucotrichophora with varying altitudes. The total basal cover was
found highest (1727.19 cm2/100 m2) on the North-East
facing slope. Q. leucotrichophora was found associated with Pinus
roxburghii as a main companion species on three faces except North-West.
The soil of Q. leucotrichophora forest on various aspects has moderate
soil pH, where maximum amount of potassium (800 kg ha-1) and
phosphorus (36.84 kg hac-1) was observed on North-East and South-West
aspects respectively, which has supported the growth of Q. leucotrichophora
forests on these aspects. It is recommended that the plantations of Q.
leucotrichophora should be done on North-East and South-West aspects
for optimum yield and sustainable development.

of two forest types; i.e. Natural forest and Plantation forest.
A total of eighty respondents were interviewed with the help of a structured
schedule. It was observed that the majority of the respondents had a moderate
knowledge of forest management. There was no significant difference in
the knowledge level of natural and plantation forest group members. However,
it was observed that more the knowledge level more was the participation
in forest management. Hence, efforts should be made to increase the level
of knowledge of members of forest user groups.

Sixty-two caregivers in a mountainous region of western Nepal were interviewed
about factors related to improving the indoor air quality. The study included
25 households with improved iron stoves and 37 households that cooked on
a traditional open fire. In a subsample of 27 households, the field team
observed kitchen characteristics and the stoves in everyday use, employing
a standardized check list. All the caregivers with improved stoves expressed
satisfaction with their stoves, whereas only 16% of caregivers with traditional
stoves were satisfied. There were no differences with respect to time spent
in the kitchen or time spent on cooking. The main motivational factors
for installing an improved stove were reduced smoke and better health.
The villagers were willing to contribute 8% of total annual annual income
per capita to have an improved stove installed. The survey identified weaknesses
in stove design that might have influenced the smoke reduction potential
of the improved stoves. This paper discusses how local conditions can determine
the motivational factors and the success of future programs for improving
indoor air quality in this setting.

Himachal Pradesh was selected as a case study using a multitemporal WiFS
data set of 1998. This study documents first the relevance of WiFS data
to assess the extent of seasonal forest. A phenologically dependent methodology
is developed for the Himalayas, where generally snow/cloud-free data set
are hardly available. Unsupervised classification using maximum normalized
difference vegetation index, band 1 and band 2 data was processed. The
hybrid approach was used to refine the classes. The classes were labelled
using the spectral values from ground truth, available data sets and spectral
anlysis of the data sets. For evaluation of classification, comparisons
were made at a regional level with the available forest database. The classes
and statistics were in correlation to the ground reality. The estimated
forest was 17.15%, whereas the forest cover reported by the Forest Survey
of India is 22.5% of the total geographical area of the state.

The mountainous tract of China falling in the Hindu-Kush Himalayan belt
experiences severe soil erosion, landslides and enormous debris flows.
The causes are complex geological structures, diverse geomorphic features,
intense neotectonic activities, recurring earthquake, anthropogenic activities
and monsoonal effect. Due to resulting recurrent damages and deaths every
year, there has been scientific and systematic mitigation efforts using
Mountain Risk Engineering (MRE) concepts in China. These have gradually
become very effective in control and management of erosion, landslides
and debris flows. Such control measures and techniques being practised
in China were observed to be effectively fulfilling the twin objectives
of stabilization and reclamation of landslides and debris flow affected
areas.

Jammu and Kashmir, predominantly a hilly state with meagre cultivable land
is supporting an overwhelming human and live-stock population. With more
than 76% of its total population being rural depends chiefly upon live-stock
(about 87,8,66) for its economy. Of the total area of state only 43.26
thousand hectares are under fodder crops. The state can ill afford to grow
fodder crops at the expense of cereals and other cash crops because of
small cultivable land at its disposal. The live-stock is mainly fed upon
cereal straw and dry grass, which otherwise, is poor in nutrition. Therefore,
it necessitates farmers to feed their live-stock on green and nutritious
fodder available to them from some indigenous and exotic taxa of shrubs
and trees so as to supplement the diet. As no literature exclusively on
the fodder trees and shrubs of Jammu and Kashmir state has been publishedso
far, the present attempt is thus made in this direction. As many as 133
plant species (87 trees and 46 shrubs) belonging to 75 genera and 38 families
are enumerated. Arachne cordifolia (Decne.) Hurusawa (syn. Andrachne
cordifolia Muell. - Arg.); Lantana camara Linn. (syn. L.
camara Linn. var. aculeata Moldenke); Padus carnuta (Wall.
ex Royle) Carr. and Lyonia ovalifolia (Wall.) Drude (syn. Pieris
ovalifolia D.Don) sometime prove fatal causing death of animals.

SERIES; NORMAL DISTRIBUTION; PROBABILITY FUNCTION]
The monthly dry days data series were used to compare commonly used distributions
and transformations for probability analysis. The observed values were
computed by Weibull's formula at different probability levels. The expected
values were estimated by Normal distribution with no transformation, Normal
distribution with Log transformation, Normal distribution with Log-Log
transformation, Normal distribution with Smemax transformation, Normal
distribution with Power transformation, Gumbel distribution and Log Pearson
Type III distribution. The comparison was made at 0.10, 0.20, 0.50, 0.80
and 0.95 probability levels. Kolmogorov-Smirnov (K-S) test and percentage
deviation were used to find the goodness of fit of the distributions. The
Normal distribution with Smemax transformation was found to be best fit
for monthly dry days data series of Pantnagar with percentage deviation
of 5.66, 3.42, 2.81, 3.19 and 6.63 at 0.10, 0.20, 0.50, 0.80 and 0.95 probability
levels.

on seed germination of twenty one tree species from central Himalalya.
Indian
J. Soil Cons.,, 28(1): 54-57. International Development Research Centre,
ICFRE, Dehradun, India. [CUMULATIVE GERMINATION CAPACITY; GERMINATION VALUE]
The paper deals with the seed germination of 21 tree species occurring
in central Himalaya under laboratory conditions. None of the species showed
seed dormancy and all the coniferous and about 72 per cent broad leaved
species indicated high seed germination. Seeds of Robinia psedoacacia
germinated within 9 days. In contrast, Carpinus viminea, Quercus leucotrichophora
and Hovenia dulcis showed late initiation of seed germination. Rate
of seed germination was higher in Robinia pseudoacacia, Albizia lebbek
and Cedrus deodara than other species.

Incorporation of growth regulators in the medium differentially affected
the activities of oxidases studied at different stages of protocorm development
of Dendrobium fimbriatum var. oculatum Hk. f. The activities
of both peroxidase and polyphenol oxidase increased on fresh weight basis
in most of the treated tissues with growth and development of protocorms
and with auxin application. However, the higher concentrations of growth
regulators were inhibitory. An increase in IAA-oxidase activity with growth
and development of protocorms was recorded in IAA, NAA, and GA3
treatments. The optimal activities of the oxidases in the tissue treated
with IAA and BAP in combination were not much different from those for
tissues subjected to individual growth regulator treatments. The contents
of total phenols increased with growth in most of the treated protocorms
except in IAA at 0.5 m M where the total phenols
were lower at stage II. The KN and GA3 treated protocorms showed
a decline in the total phenolic content with growth. The o-dihydroxyphenols
decreased with growth in the treated protocorms except for IAA (10.0 m
M), NAA (5.0 m M), and BAP (5.0 m
M). The study also suggests that growth regulators in the medium may act
in a manner similar to ednophytic fungi, which form symbiotic association
with germinating seeds in nature, and bring about the physiological changes
during protocorm development.

ENDOGAMY; KHASI-MUSLIM; POPULATION]
The present study has been carried out among the Khasi-Muslim population,
residing in the capital city of Meghalaya, Shillong. The Khasi-Muslim is
a resultant population which has emerged out of the inter-marriages between
the various matrilineal Khasi subtribes and different non-tribal immigrant
Muslim populations, who came from other parts of this country and eventually
settled here. Besides the demographic composition, the present study indicates
that the admixture rate was quite high in this comparatively small population
of recent origin. Selection pressure was moderate, with greater contribution
of different fertility than differential mortality. The Khasi Muslims choose
mates mostly from within the group indicating that they have maintained
and established themselves as a separate religious endogamous group within
the Khasi fold.

ECONOMY; POLICY CONFLICT; SUSTAINABLE ECO-TOURISM]
The fascination for mountains, breathtaking natural beauty, rich cultural
diversity, socio-economic traditions, history and lifestyles attract mountaineers,
trekkers, naturalists ascetics, explorers and cultural tourists from all
over the world to the Nanda Devi Biosphere Reserve (NDBR) and adjoining
areas. Expedition/mountaineering and tourism, as a livelihood option for
the people living in the buffer zone areas of NDBR, was important, next
to animal husbandry and agriculture. Until 1960, Bhotiya people in the
buffer zone of NDBR and adjoining areas had a good trade relationship with
Tibet. Closure of Indo-Tibetan trade due to the Indo-China war of 1962,
followed by imposition of conservation policies due to creation of Nanda
Devi National Park in 1982 and Nanda Devi Biosphere Reserve in 1988, caused
all consumptive uses and expedition/mountaineering to be banned in the
core zone, which has not only affected the local economy to a large extent
but also created conflict between local people and reserve authorities.
The ban on tourism is the most severe concern of the local people as it
provided significant income. Of the three complementary functions of a
biosphere reserve, viz. conservation, development and logistic support
(research and education), the management is biased towards achieving conservation
by legal protection which may not be sustainable in the long term. People
have started raising a voice against the ban on expedition/tourism in the
core zone but have not yet damaged the core zone area. This paper deals
with the history of expeditions and the impact on the local economy, identification
of model ecotrekking/expedition routes and potential sites, and designing
appropriate strategies/action plans for sustainable ecotourism. This will
not only help to resolve the local people-policy conflicts and improve
the local economy but will also help to achieve the biodiversity conservation
goal.

BLACK TENT; MOBILE HOUSING; NOMAD; PASTORALISM; TIBETAN PLATEAU]
Black tents serve as mobile housing for a majority of the nomadic groups
in a belt that stretches from the shores of the Atlantic Ocean to the eastern
Tibetan Plateau. The existence of the black tent in its easternmost distribution
has rarely been discussed in detail. In most regions, the requirements
of the tent are determined by hot, arid climatic conditions, whereas an
arid high mountain climate predominates on the tibetan plateau. The eastern
part receives precipitation of over 500 mm annually. This raises questions
about how Tibetan nomads have adapted the black tent to their specific
needs and to environmental conditions. Using examples from a region in
the eastern Tibetan Plateau, these questions are examined through descriptions
of tent variations, construction, interior, choice of location for pitching
the tent, and the strategies of tent dwellers to improve protection from
cold and rain.

low population pulse of 995 individuals/m2 in February in Coniferous
forest stand, and 7132 individuals/m2 in April against a meagre
population of 903 individuals/m2 in January. Natural ecosystem
and animal life greatly influenced the physio-chemical properties of the
soil. High degree of aggregation and efficient adaptability for diverse
environmental conditions is the basis for density, diversity and dynamics
of acrofauna population in soils.

Abundant fossil bone fragments of dinosaurs have been found at Dirang village
near Ranikor, West Khasi Hills district, Meghalaya. These bone fossils
occur within a four to five metre thick coarse grained purple-coloured
sandstone horizon of Mahadek Formation of late Cretaceous (Maestrichtian)
period. The bones are poorly preserved and fragmentary in nature, as a
result of the prevailing high energy condition in the depositional basin.
The size, shape and nature of the bones; palaeohistological studies under
microscope as well as continental type of environment for the animals thriving,
confirmed dinosaurian origin for these bones.

Studies on phenology and growth form distribution in an alpine pasture
of Garhwal Himalaya were undertaken from 1988 to 1998. One hundred seventy-one
species were recorded and classified as 5 different growth forms. These
species were also classified as early-and late growing type, on the basis
of initiation of their aerial sprouts. Cushion-forming forbs generally
emerge as the season commences, that is, immediately after snowmelt. However,
the vegetative growth of grasses and other forbs peaked randomly after
arrival of the monsoon. Phenophases of different species at higher elevations
respond to the availability of the soil moisture and nutrient regimes as
well as to temperature and different photoperiodic induction. The spectrum
of life forms in the region indicated a hemicryptophytic and geophytic
plant climate.

[NUTRIENT CONTENT; ROOT COLLAR DIAMTER; SEEDLING]
The influence of root collar diameter of ten months old nursery raised
seedlings on first year outplanting survival and growth of Grewia optiva
and Ulmus villosa was evaluated. Both the species were planted in
field during the first week of January, 1997. Initial root collar diameter
at planting ranged from 2.83 to 6.24 mm for Grewia optiva and 3.01
to 7.10 mm for Ulmus villosa. After one growing season, results
showed a significant relationship of root collar diameter to outplanting
survival and growth. viz., height and collar diameter increment,
shoot and root dry weight and leaf nutrient contents (N,P,K) of both Grewia
optiva and Ulmus villosa. Root collar diameter had significant
effect on outplanting survival of Grewia optiva while the same was
not good predictor of outplanting survival of Ulmus villosa after
one growing season.

of Botany, H.N.B. Garhwal University, Srinagar 246174, Uttaranchal, India.
[FICUS PALMATA; LEAF GROWTH; VEIN-ENDING; VENATION PATTERN]
The sequential development of a leaf usually has four well-defined phases,
viz.:
(a) Initiation of the leaf primordium, (b) Further development of individual
leaf, (c) Growth of the leaf surface as a whole in relation to the life-history
of the plant, and (d) Influenceof various mechanisms controlling leaf initiation
and growth. The new leaves start appearing in Ficus palmata during
end of February and the first week of March and continue to do so till
June and July. For the present study, the leaf sample had been collected
from a healthy three growing in the study area and their outlines were
traced on a sheet of graph paper for estimating the leaf area. The leaves
show a sigmoid pattern during their growth (in volume) in a total period
of 20 days. During this span its size increases from 36 mm2
6,160 mm2, as recorded by the average size of the mature leaves.
The percentage gain of the leaf area has been found to be highest on the
third days (89.28%). The vascular system comprises a single main vein (the
midrib or 1o vein) which passes through the centre of the lamina.
Subsequently, secondaries, tertiaries and quaternaries are formed alongwith
the intermediaries. At the early stage of leaf development, the number
of areoles per unit area is low (large areoles) but at maturity it increases
(smaller areoles). As regards the number of vein-tips/vein-endings per
areols, it varies from 0.1 on the first day of emergence to 1.4 between
fourth and six day. Its further growth is usually regarded to be the product
of divisions, expansion and subsequent differentiation of the component
cells, comparable to the other plant organs. The highest number (11.8)
of vein-tips in an areole has been observed at the later stages of leaf
growth. It can thus be stated that the leaf of this species is indicative
of initial rapid growth.

Aconitum heterophyllum Wall. and A. balfourii Stapf. are important
medicinal herbs of the Himalayan region. The effect of plant growth substances
(PGSs, nemely, abscisic acid, 6-benzylaminopurine, gibberellic acid and
zeatin riboside) and two nitrogenous compounds (thiourea and potassium
nitrate) for enhancing and synchronising uniform germination was examined.
The tetrazolium (Tz) staining pattern indicated that freshly collected
seed had high viability which decreased following storage at 40C
for 6 and 12 months. The treatments and time to seed germination were found
to be significantly different (P<0.01). Gibberellic acid (GA3;
250 m m) significantly enhanced seed germination
(42.5% compared to 27.5% in control) in A.balfourii with in 15 weeks
but was inhibitory in A. heterohyllum. 6-Benzylaminopurine (BAP;
25 and 250 m M) and zeatin riboside (ZR; 25
and 250 m M) did not enhance germination in
A. balfourii; 250 m M ZR was actually
inhibitory. In A. heterophyllum the lower concentration of BAP was
inhibitory (7.5% compared to 25.0% in control) while 250 m
M BAP enhanced germination (42.5% compared to 25.0% in control); the higher
concentration of ZR was inhibitory. The combined treatments of gibberellin
and cytokinin in general resulted in reduced germination in both species.
Among the nitrogenous compounds, thiourea (CH4N2S)
increased the rate and germination percentage in both species but potassium
nitrate (KNO3) enhanced germination in A. balfourii only.
Seed germination was first detected in A. balfourii in the 5th week
(2.5%) following treatment with 65 mM CH4N2S
and this value increased to 22.5% in the 7th week and reached as high as
75% (compared to 27.5% in control) in the 15the week. A higher dose of
thiourea (130 mM) resulted in a rapid and high
germination rate (40% compared to 0% in control) in the 7th week, reaching
75% in 10th and 12th weeks and a maximum 80% (compared to 27.5% in control)
in the 15th week. In A. heterophyllum, however, thiourea only marginally
enhanced germination even up to the 15th week. In A. balfourii,
KNO3 (50 and 100 mM) significantly
enhanced germination (62-70%) within 15 weeks.

An adequate and reliable supply of energy is a prerequisite for development.
In Nepal, forests and water are the two major indigenous energy resources.
Forests are being overexploited in many parts of the country, mainly for
fuelwood, whereas water resources are underutilized with regard to their
capacity to generate hydroelectricity. Nepal might be able to control forest
degradation by adopting a differentiated approach to hydropower development.
The prospects and the risks of such development are discussed here, and
three scenarios that have received increasing attention in recent years
are presented for implementation in a wider South Asian context.

Red panda, Ailurus fulgens is a poorly known Himalayan member of
Carnivora which has adapted to a herbivorous diet. The present study conducted
in the Singhalila National Park in the eastern Himalayas was initiated
to gain information on the ecology and conservation problems of the red
panda. Indirect and direct evidence was used to assess its distribution,
relative abundance, habitat use and food habits in the National Park. Red
panda was relatively more abundant within an altitudinal range of 2800-3600
m. In study sites 1 and 2, it had a very narrow preferred range of 2800-3100
m. Higher bamboo cover, bamboo height and canopy cover emerged as important
habitat components in sites used by red panda (Animal centered plots) compared
to random plots. Red panda diet consisted chiefly of bamboo leaves and
both species of bamboo, Arundinaria maling and A. aristata
predominantly present as understorey in Singhalila National Park were eaten.
The diet of bamboo was supplemented by seasonal fruits and bamboo shoots.
However, the composition of diet differed between the three study sites
and the impact of this, if any, on the overall ecology of red panda in
the Singhalila National Park, needs further investigation. Some conservation
problems are discussed.

An experiment was conducted at Selakui Research Farm (Dehradun) monoclinal
runoff plots to quantify the effect of 0.5, 2.5, 4.5 and 9.5 per cent land
slopes on erosional losses and maize wheat productivity. The loss of water
(runoff). Soil and nutrients increased as the degree of slope increased.
The runoff increased by 39.8, 89.8 and 151.5 per cent; soil loss by 109.8,
331.7 and 587.8 per cent; and loss of nutrients (available N,P and K, and
exchangeable Ca and Mg) by 69.0, 117.3 and 165.9 per cent with increase
in land slope from 0.5 to 2.5, 4.5 and 9.5 per cent, respectively. Grain
yield of maize was similar at 0.5-4.5 per cent slope but decreased by 15.9
per cent at 9.5 per cent slope. Wheat grain yield was highest at 0.5 per
cent slope and decreased by 3.8, 24.7 and 36.3 per cent at 2.5, 4.5 and
9.5 per cent slope respectively. The decrease in yield at higher slopes
was associated with reduced availability of soil moisture at different
growth stages of wheat. Regression analysis indicated that runoff and soil
loss increased by 18.35 mm and 2.73 t ha-1, and maize and wheat
grain yield decreased by 42 kg ha-1 and 154 kg -1,
respectively with a unit increase in land slope. These results suggested
that wheat cultivation was risky but maize produced stable yields at moderate
slopes under Doon valley conditions.

WATER POLLUTION]
In Nepal, water in many rivers is being polluted by the industrial effluents.
In the present study, water from seven sites in the Narayani River was
analyzed for various physico-chemical parameters like pH, temperature,
conductivity, turbidity, total suspended solids (TSS), dissolved oxygen
(DO), biological oxygen demand (BOD), chemical oxygen demand (COD) and
total alkalinity. Similarly, the amount of ammonium-N, nitrate-N, nitrite-N,
total phosphate, sulphate, sodium, potassium, calcium, magnesium, iron,
manganese, zinc, lead, copper and boron were also determined. Based on
the volume of the effluents, discharged by the industries into the Narayani
River, the most polluting industry is the pulp and paper industry. Results
showed that the water in the river gets polluted after receiving the effuents
from the paper industry and again it becomes free of pollutants downstream.
Some of the parameters remained relatively uniform throughout the stretch
of the river whereas the values of pollution indicating parameters such
as pH, conductivity, suspended solids, alkalinity, some nutrients and heavy
metals were higher near Gaindakot, just after the input of paper industry
effluents. This study concludes that there is the need for proper treatment
of industrial effluents before discharging them into the river.

This article discusses the efforts directed in educating the Rajis, a nomadic
tribe of the Central Himalayan region of India, the outcome of the efforts
and the impacts, the constraints and the prospects associated with the
process of education. Efforts to promote education are being made by the
Provincial and the Union Government of India to develop this numerically
reducing and under developed nomadic tribe. The tribe has achieved an effective
literacy percentage of 35.06. However, a wide gap galores between male
(50.68%) and female literacy (16.66%). Moreover, the problem of educational
development among this nomadic tribe has been very complex. Uniformity
in the reading material subscribing text books, and guide book containing
material unfamiliar to the child; ecologically and culturally incompatible
curriculum, unfamiliar language of the text books, etc., imposed
a learning on this people with no relevance to the environment. Lack of
opportunity for higher education and its application in promoting the quality
of life particularly from the point of view of economy, non-effective administration
and organizational failure, non-cognizance of significance of ecological
and socio-cultural specificities, etc., were major factors in the
non-promotion of education among the Rajis. It was also observed that Non
Governmental Organizations were being more effective in promoting education.

This paper analyses the spatio-temporal aspects of development of tourism
industry in Sikkim. Though, the industry had a late start and is yet to
gain importance at the international level, it has grown significantly
since late 1980s. Accessibility problem is found to be one of the major
obstacles in development of tourism in this picturesque and culturally
rich state of Sikkim. Summer and Autumn are the two peak seasons, whereas
Monsoon and Winter are the two lean seasons of tourism activity in the
state. Most of the tourism activity in the state is found to be concentrated
in and around the state capital, Gangtok.

Soil Science, HPKV, Palampur, H.P., 176062, India. [FUEL-WOOD; LAND DEGRADATION;
LOWER SHIWALIKS]
A fuel wood survey was conducted in the lower Shiwaliks of Una district
of Himachal Pradesh to determine fuel wood demand and related socio-economic-environmental
parameters of its extraction. A total of 117 households of hills and plains
constituting small, medium and large farmers formed the sample of the study.
Community lands were depleted of harvestable biomass but, the annual fuel
wood demand per household worked out to be 4.67 tons. The total annual
requirement of the region was, therefore, 2.8 lakh tons, far exceeding
the yields of 91,000 tons in the region. The government forests and private
lands formed the main sources of wood supplies in hills and plains, respectively.
The share of dry, green and mixed (dry+green) wood was 16,38 and 46 percent
respectively in the area. Individual from each household traveled, on an
average, 6-7 km to fetch fuelwood and were aware about environmental degradation.
The quality of wood was better in 1980 compared to 1990. While the whole
family is involved in collection of fuel wood, the children from the hills
shared the burden more than their counterparts in the plains. The region
calls for the establishment of energy plantations in community and private
lands on a large scale.

This paper analyzes spatial variation in species diversity of aquatic macrophytes
in terms of species richness, species evenness, plant mass index and similarity
index in two morphometrically different Lake Phewa and Lake Rupa of subtropical
Pokhara valley, Nepal. Vegetation mapping methods including GIS and semi-quantitative
Kohler Indexing approach were applied. Leke Phewa is a relatively deep,
large and dam-regulated semi-natural lake ecosystem with urban anthropogenic
influence whereas Lake Rupa is relatively small, shallow, natural lake
with less human impact. A total of 56 species of aquatic macrophytes belonging
to 5 growth forms were reported along with higher species diversity of
hydrophytes and helophytes in Lake Phewa and Lake Rupa, respectively. Most
species were of common occurence but some species were found exclusively
in either of the two lakes. Distinct variation was noted in relation to
their plant mass index and association of communities. The study suggests
that monitoring of influential factors like siltation and cultural eutrophication
hold importance for the conservation and management of biodiversity of
aquatic macrophytes in particular and health of subtropical lake ecosystem
in general.

The process of urbanization in Himachal Pradesh was initiated along with
its emergence. The state's urban growth was fast compared to the rural.
The state had a static structre. A clear strip of space from NW to SE direction
act as a divide between more urbanized and less urbanized areas. The process
of urbanization is more administrative than spatial development. The variation
in the regional growth is the important feature. The towns are in the process
of gathering the economic and other activities. Due to the development
of industries and hydel projects the process of diffusion of urban centres
started. The older Himachal Pradesh is more urbanized than the new Himachal
Pradesh. The small and medium towns are prevalent in the urban scene of
Himachal Pradesh.

(geographic lat. 27.8oN, long. 78oE). The results
show that electric field perturbations started appearing in the form of
noise bursts 16 days prior to the occurrence of the main shock on 29 March
1999. In majority of the cases of the noise bursts the effect was observed
by borehole antenna only, indicating that the signal propagated through

through conductive channels along Delhi-Haridwar ridge and parallel to
them between the source and the observing station.

north-west Himalaya. Journal of Non-Timber Forest Products,

VALUE; GEOGRAPHICAL BOUNDARIES; MEDICINAL PLANT]
Twenty taxa of medicinal and aromatic value distributed in the North-west
Himalayan region extended from Jammu and Kashmir to western borders of
Nepal have entered the category of threatened plants due to large scale
and indiscriminate collection in the past. At least one of these, i.e.,
Ferula
narthex has already been wiped out from geographical boundaries of
the country while the survival of three others,
i.e., Aconitum
chasmanthum, A. deinorrhizum and Dactylorhiza hatagirea is unlikely
if present causal factors continue to operate. There are about a dozen
or so taxa which are highly vulnerable. These include some which have been
over-exploited for commercial purposes, while others have been exposed
to the danger due to deforestation, habitat destruction,
etc. This
is more so in the case of plants endemic to Mediterranean type of climate
in Jammu & Kashmir such as the species of Atropa, Angelica and
Colchicum.
The paper highlights the threats involved in each individual case and suggests
remedial measures. It identifies certain areas within the region which
can be declared reserves to protect the germplasm. It also suggests cultivation
of some of the threatened plants on lines with
Saussurea lappa, Inula
racemosa and Bunium persicum, successful cultivation has brought
these medicinal plants out of the endangered list.

A large number of wild growing plants of their parts (tuber, leaves, flowers,
fruits, seeds, grains, etc) still supply food to large section of
human beings in mountain areas, particularly in the entire Himalayan and
north-eastern region of India. Sikkim though a tiny hill state in Eastern
Himalayan renge, possesses as many as 190 wild plants of food value as
identified in the present study. A large number of wild edible species
are nutrient rich, thus useful to local diets. As many as 43 wild edible
species are sold in the markets with an annual turnover of 140 tons, and
provide an important source of money earning to the subsistence of farmers.
Unfortunately these plant resources are considered as free-access exploitable
materials, and have been neglected due to various reasons. This paper highlights
an urgent need to understand the potential of wild edible plants in the
Sikkim Himalaya with particular reference to their diversity, usages, nutritive
values and marketing, and also emphasizes that suitable policies may be
formulated for their proper exploitation and conservation in natural habitats.

The land use of two districts in western Nepal was classified into forest
and non-forest by satellite imagery with different topographical corrections.
The accuracy of the forest biomass and timber volume estimates was also
tested. The forest areas were interpreted correctly, with an accuracy of
82-88%. The best result was derived when the Minnaert constants of forest
were separated from those of other land uses which were combined. The timber
volume and biomass estimates were computed using the weighted nearest neighbour
method. The coefficients of determination were 0.06 for timber volume and
0.09 for biomass. The use of the existing land use data seems to have potential
for improving the results of topographic normalization. Because the reflectance
in mountainous areas depends on many vegetative and terrain features, the
simple non-Lambertian correction over broad categories did not significantly
improve the results.

communities in India. as many as five tribal communities reside in the
Central Himalayan region of India. These communities are unique in their
culture, resource use pattern and in their relation with their environment.
Efforts to develop these communities have been accelerated by the government
in post-independence planning era, and perceptible development have occurred
in their social and economic life. However, difference in the social and
economic conditions are clearly visible in these communities which are,
largely, effected by resource base, culture and also ecology. In this paper,
an effort is being made to understand the variation in social and economic

i.e.,
the Jaunsaries, the Bhotias and the Rajis, constitute about 35.62% of total
