Seedlings of19 important species (exotic and indigenous) were raised in nursery. These species were planted in the project area. And survival rate and height were measured. In the first year of plantation maximum survival per cent (l00 %) were recorded for Acacia delbata, Acer oblongum, Aesculus indica, Fraxinus micrantha, Grewia optiva, Prunus cerasoides and Robinia pseudoacacia. In the second year maximum survival per cent ( >90 %) were found in Acer oblongum > Robinia pseudoacacia> Grewia optiva, > Fraxinus micrantha. In the third year maximum survival per cent were recorded (>80 %) Grewia optiva > Ficus roxburghii > Acer oblongum > Ficus glomerata >Aesculus indica. Maximum height were recorded in Alnus nepalensis > Salix alba >Robinia pseudoacacia > Acacia mearnsii > Acacia melanoxylon after the completion of third year.

A study based on questionnaire was conducted from August to December 1994 with the objective of analyzing some of the socio-economic implications influencing people's participation in silvipastoral activities in the villages of Pidligad Micro Watershed ofGarhwal Himalaya. Statistical tests revealed that farm size, household size, total number of animals in the household and distance travelled in fuelwood collection were statistically significant at 95% level. Number of days used for fodder collection was not statistically significant. The study recommends that detailed analysis of the clientele sliould be prerequisite in any silvi-pastoral activities to be undertaken.- Electrophoretic Fractionation of the Soil Humic Acids of Chakrata Himalayas (U.P.)

Soil humic substances of Chakrata Himalayas was subjected to electrophoretic examination for their molecular weight make up. The humic substances of the soils under deodar, spruce, fir, oak and kharsu were having higher molecular weight than under chir and kail with accumulation on the surface horizons rather than sub-surface ones. Since the molecular make up of the humic substances is regarded as the fertility indicator in the soil, it was concluded that the soils under, deodar, spruce, fir, oak and kharsu were more fertile than the soils under chir and kail.- Mean Annual Increment in the Forests of Garhwal Himalayas Related with Soil and Ground Litter Properties

Soil humic acids from the Garhwal Himalayas were subjected to electrophoretic fractionation according to different molecular weights. It was found that there was a great deal of difference in the extent of migration of humic acids in different zones, dependeing up on the origin and mode of deposition of the humic acids. Thus indicated diffennce in the molecular weight and fertility status. The study also revealed that comparatively deodar had low molecular weight humic substance, compared with chir and oak and the same had accumulated at the surface to depict its better ferlility.- Quantitative Ecological Analysis of Some Woody Species of Mussoorie Himalayas (U.P.)

A detailed ecological study was carried out at eight different sites of Mussoorie Himalayas (Uttar Pradesh) supporting mainly Cedrus deodara, Pinus roxburghii and Quercus leucotrichophora. During the course of study it was found that although the density of these species varied between 1.9 and 6.4 trees 100 m2. Their pattern of distribution was mainly randon and some where regular. However, their total basal cover varied between 160.87 and 9257.52 cm2 100 m2 and mean basal area between 280.31 cm2 Tree-1 and 3627.94 cm2 Tree-1.- Study of the Soils of Mussoorie Area (Garhwal Himalayas)

Certain soils of Mussoorie forests under Deodar (Cedrus deodara) , Chir (Pinus roxburghii) and Oak (Quercus incana) were studied for their various physical, chemical and physicochemical attributes and classified in to four classes viz, Typic Hapludolls,Typic Dystrochrepts, Typic Argiudolls and Ruptic-Alfic Eutrochrepts. Typic Hapludoll, identified under Deodar and Oak were not much influenced by vegetation whereas Typic Dystrochrepts encountered uDder Deodar and Chir expressed higher order of interaction of vegetation on soil development. The soil development process of Typic Argiudolls found under Deodar were influenced by the vegetative cover in contrast to RuptiC-Alfic Eotrocbrepts under Chir cover.- Investigating the Water-table under Eucalyptus Hybrid by Resistivity Method

Hydrologically it is important to distinguish phreatophytic vegetation, as the access to the water-table enables plants to transpire the full potential and not conserve water. However,there is much misunderstanding outside the hydrological discipline on the location and behaviour of the water-table. We describe the methods of wells and electrical resistivity which we have employed in the Terai Eucalyptus plantation to study the water-table, and we discuss the preliminary results which as yet demonstrate little direct abstraction by the trees from water-table deeper than 1.5 metres.- Qualitative and Quantitative Assessment of the Soil Organic Substances Present in the Forest Litter of Chakrata Himalayas (Uttar Pradesh)

The biochemical composition of the forest litter, before and after its incorporation in to the mineral soil was studied in certain forest areas of Chakrata Himalayas (U.P). It was found that although the humus type was 'Orthirhizomull' under all the species under investigation viz. Cedrus devdara, Pinus wallichiana, Pinus roxburghii, Picea smithiana and Abies pindrow its composition, in terms of recognisable organic substances was different from species to species. The litter under P. roxburghii and P. wallichiana was richer in cellulose and hemicellulose content while others in fats, waxes, oils and water soluble polysaccharides contents. Conversion of these substances into high molecular weight compounds was on account of decomposition and synthesis by the primary and secondary flora.- Study of the Humus Forms in Some Ecosystems of Chakrata Forest (Dehra Dun) U.P., India

Special features of the soil organic materials, present in the forests of Chakrata Himalayas (U.P.) were studied in respect of their nature, distribution and type for the purpose of interpreting their suitability under various forestry management practices. The study indicates that the prevailing favourable conditions of these habitats viz. good aeration, balanced moisture supply, favourable temperature and easily decomposable litter along with fairly good nutrients reserve have given rise to a 'Orthirhizomull' type of 'Humus form' which is supposed to contain a stable c1ay-humus aggregations suitable for intensive cultivation and is least susceptilble to ground fires and fertility losses.- Spectral Properties and Colloidal Rehaviour of the Humic Acids of the Soils under Oak (Quercus incana), Dfodar (Cedrus deodara) and Chik (Pinus roxburghii) of Mussoorie Himalayas (U.P.)

The humic substances of the Mussoorie Himalayan soils (U.P.) under different vegetation covers, Were characterised with the help of non-degradative spectrophotometric methods. The ratios of optical densities or absorbance at 465 mp. And 665 mp. In respect of dilute aqueous humic acids was used as the indicator of carbon in aromatic nuclei and in alphabetic side chains. It was noticed that the absorption of light increased with the increase in the degree of condensation of the aromatic rings in them and was depleted by a lower E4/E5 ratios and lesser absorptions. As Such it was found that the humic substances under Chir (Pinus roxhurghii) contain large proportion of aliphatic structure in them in comparison to Deodar (Cedrus deodara) and Oak (Quercus incana) were the humic substances were more condensed with aromatic rings. The later were also found to be hydrophobic in nature with lower coagulation threshold values as compared to former and as such were more akin for tbe favourable soil aggregation.- Comparative Study of the Bio-chemical Compositton of the Plant Materials in the Mussoorie Himalayan soils (U.P)

A detailed phytosociological analysis of woody species of Chakrata forest at twelve different sites supporting seven tree species viz., Cedrus deodara, Pinus roxburghii, Picea smithlana, Pinus wollichiona, Quercus florihunda, Q. semicarpifolia and Abies pindrow was carried out. Their total basal cover varied between 1455 and 5672 cm2 100 m-2 and total density from 0.7 to 3.7 trees 100 m-2. The distribution pattern was random for most of the species. The species diversity was greatest in Pinus wallichlana forests followed by Quercus floribunda forests. However, the values of concentration of dominance, exhibited inverse relationship with the species diversity.- Measurement of Hexoses in Acid Hydrolyslates of some Soils of Mussoorie Himalayas

Clay mineralogical characterisation of soils of four different natural vegetational sequences of South Kheri forest division has been attempted. Sand mineralogical analysis revealed that the soils have developed from the same source. Hence differences in their characteristics might have been triggered off by the diversity in their vegetative cover. Ellite was present in all the soils with different relative propositions. Vermiculite, mixed minerals and chlorite seem to be present in higher amount in Argiustolls, Haplustolla and Haplustalfs having more diversity in their natural vegetation. Ellite dominated in Ustochrepts under a purest and of Shorea robusta. More alteration of Ellite or neo-synthesis of vermiculite and chlorite seems to have taken in soils with comparitively wet soil moisture regims as evidenced from the natural groeth of moisture loving indicator species like Syzygium cumini and Terminalia alata.- Classification of Soil Biosequences in Relation to Vegetation - I.

Some soil biosequences occurring on a nearly similar toposequence have been classified with special reference to the role of natural vegetation on thier genesis. Sandy hyporthermic typic Haplumbrept and Ustochrepts are the major silviculturally important soils of this area. From the organic carbon content (Organic productivity turn-over) and its relative distribution along depth, comparision of base status in different horizons and clay migration, it appears that marks of grassy woodland ecotones on the genesis of Argiustoils are quite evident. Thick B-horizons, migration of clay, lower base saturation, gradual decrease in organic carbon and redistribution of exchangeable Ca and Mg possibly due to phytocycling among various horizons indicate the dominant role played by tree species in the comparatively more weathered habitats of Udic Haplustalfs. Silvicultural suitability of different taxas have been discussed.- Characterisation of Soils in Relation to Site Index of Eucalyptus Tereticornis

Variation in site index (S.I.) of 4-13 year old Eucalyptus plantations have been discussed in relation to physico-chemical characteristics of soil of Tarai Central Forest Division. S.I. ranged from 15.2 to 25.8 metres at an index age of 8 years. S.I. was generally higher in Aquolls and Udolls of lower peidmonts (Tarai) where soil characteristics associated with excessive wetness were observed. However, high pH due to distribution of CaCO3 throughout the profile affected site index adversely. Growth of Eucalyptus was the lowest in skeletal Haplustolls of upper peidmont (Bhabar) because of the presence of gravels and pebbles. Sandy texture of non-skeletal Haplustolls also seem to have lowered the S.I. in the transition zone between upper (Bhabar) and lower (Tarai) peidmonts. Roots were crinckled, twisted and bunchy in appearance indicating restricted distribution in skeletal soils.- Soil Biosequences of a Forest Land of Dun Valley with Reference to its Vegetation

Interrelationship between the soils and vegetation have been discused in respect of a forest land of Dun Valley (U.P.) having sal (Shorea rabusta), teak (Tectona grandis) and miscellaneous species as its main vegetation. The soils under various types of vegetation differ marginally from one another at various levels. The soil under teak and miscellaenous species contain comparatively more available nutrients than soils under sal, which has otherwise sustained greater interaction by vegetation during the course of their development.- A Comparative Study of Saline-sodic, Sodic and Normal Soils in Relation to forest Growth of South Kheri Forest division, (U.P.)

A soils investigation was conducted in April. 1979 in some salt-affected and normal soils of South Kheri Forest division (U.P.) in order to compare (I) saline-sodie soils where all forest species have failed to grow, (ii) sodie soils having fair growth of some tolerant forest species, and (iii) Normal soils having good stand of natural sal forest. These soils vary widely in several morphological. Physical and chemical characteristics and accordingly, the forest species have shown varying growth response. In general, all forest species have failed to grow on CO3-CI type saline-sodic soils which are compact and indurated with cemented bed of CaCO3 (kankar) nodules mixed in clay pan, have drainage donditions very poor, pH>9.5, ESP>40 and EC> 4 m mhos/cm. Few lines on reclamation of these soils have also been suggested. Tendu (Diospyros tomentosa). Dhak (Butea monosperma) Mahus (Madlmca indica). Dudhi (Wrightia tomentosa). Jamun (Syzygium cumini) and Rohini (Mallotus philippinensis) are able to grow on CI-HCO3 type sodic soils having a maximum pH value 8.0. EC of saturation extract 4 m mhos/cm at 25°C and ESP 10 in top one metre deep soil but in subsoil tolerance of plants may go upto the values of pH 9.3, ESP 40 and EC 4.

Chemical composition and the proportion of primary minerals in the silt fractions were studied in the soils of Mussoorie Hills (U.P.), which have developed over different parent materials under varying climatic conditions and vegetation. The study reveals that the silt fraction of the soils developed over shales under oak contains a relatively lower proportion of heavy minerals and a higher proportion of light minerals as compared to those developed over limestone under conifers indicating thereby more podzolization and less illimerization in them. Alteration of kaolin into muscovite and accumulation of quartz muscovite and heavy minerals in the surface lowest and illuvial horizons respectively, of the former also indicate more podzolization and intense weathering in them as compared to latter which were rich in calcite, dolomite and other resistant minerals.- Electrophoretic Fractionation and Characterization of Humic Acids of the Soils of Doon Valley under Sal (Shorea robusta)

Total polysaccharide content of soil hydrolysates (hexose, methyl hexoses and 6-deoxy hexoses) which reacts with anthrone was measured in some sal forest soils of Doon Valley, growing presently Eucalyptus. The comparative study of the nature and content or carbohydrates in the soils under two vegetations reveals that the growing of Eucalyptus in sal areas has not only increased the content but also altered their nature in the following quinquennium, by way of increased polymerisation and resistance towards electrolytes, and decreased dispersion, which are helpful from the point of view of structure formation and fertility status.- Mortality of Eucalyptus at Haldwani (U.P.) and its Relation with Soil Iron

An investigation to study the probable causes of chlorosis in E. tereticornis revealed that a physiological disorder under specific environmental condition caused unavailability of soil iron. High level of phosphoras in the growth medium reduced the absorption and utilization of iron under slight alkaline-calcareous condition whichh also inhibited iron availability to the plants besides oxidising. It into less active ferric state and compounds of low biological activity resulting in disturbed metabolic activity of the plants.- Comparative Determination of the Spectral Properties and Colloidal Behaviour of Humic Acids of Sal Forest Soils of Doon Valley Planted with Eucalyptus

The conditions of Eucalyptus monoculture has promoted the formation of humic acids in soils with a clearly expressed aromatic rings as comapared to surrounding sal. Correspondingly the number of peripheral chains has decreased and the hydrophillic nature is less marked; humic acids are only slightly dispersed and coagulate even with small amounts of electrolyte.- A Comparative Study of some Typical Sal Forest Soils of Doon Valley with Reference to their Organic Matter

A considerable difference in the nature or humus was observed in the two typical sal forest soils of Doon Valley. The humus of the soils obtained from Asarori is predominantly humic in nature with greater condensation of aromatic rings and thus more mature as compared to that of Jhajra which is more lignious and fulvic in nature, containing more of side chains. Greater hydrolysability, oxidisability and mobility of humus of Asarori have been responsible for better soil conditions from the point or view of site quality and also nutrient cycling.- Timber Floating in Godavari, Indravati and Pranhita Rivers

Trend in the changes in peroxidisable, alkali-extractable, and acid-hydrolysable fractions of the soil organic matter under Eucalyptus monoculture and surrounding natural sal in the course of a quinquennium reveals that the former humifies easier and faster. Oxidisability of resistant organic matter of the surface samples increases under both but the non-peroxidisable carbon decreases in all the layers under Eucalyptus as compared to surrounding sal. Optical densities of the alkali- extractable organic fraction, in general, increases and more so in the surface layers, reflecting certain changes in the nature of the organic matter returned during this period. Translocation of the humified material is more pronounced under Eucalyptus although to a limited depth. Soil organic matter under Eucalyptus is more hydrolysable, and non-hydrolysable fractions decrease very significantly under sal as compared to Eucalyptus.- Ecological Analysis of Some Woody Species of Mine Affected Areas of North-West Himalayas
