U.P. Hill Region forests are fast degrading. Though this is causing many problems but fuelwood scarcity is most acute. In rural areas fuelwood demand is estimated to be about 3.5million tonnes. Most of it stands as deficit and met through irregular removals. The lands and funds required to meet the deficit by raising plantations are rather physical impossibility. In addition to plantations both inside and outside forestry, socio-economic development and providing alternate sources of energy have been suggested. Yields from the forests should be assigned for meeting local rural needs. Efficient protection and management of the existing forests should be aimed at for increasing their productivity. Efficient and just distribution systems and participation of local people in creation and management of assets have been emphasized. Some tree and shrub species have been suggested for raising fuelwood crops both in the forests and agri-ecosytems. Study of the problem in proper perspective and carrying out research thereon need proper and adequate attention. Linking firewood problem with over all energy programme has been indicated. Eco-system diagnosis and cure approach should be adopted. Some policy and technical aspects pertaining to forest management in general and fuelwood supply in particular have been given.

Productivity in relation to forests needs to be defined properly, yield of wood alone through silvicultural operations is not a correct expression of forest productivity. Various direct and indirect productions obtained from the forest need to be accounted for when calculating productivity of a forest. There is need for devising some rational formula for calculating productivity index. This formula should be able to accommodate the manipulatable factors like soil and biotic factors. Modern scientific developments can influence forest productivity considerably and hence it can be classed as real or induced also. Depending on the objective of management of forest system, forestry may have to be recognized as'Environmental Forestry' and 'Production Forestry.' The concept of productivity in both will not be the same. Biotic factor treatment concept needs to be adopted and practised to enable forests to yield their full potential of productivity. In programmes of increasing productivity through plantations, wasteland development and normal forestry practices ecological considerations need to be scrupulously taken into account.- Forestry Seed Development

Seeds of Aesculus indica shown immediately after collection in the month of October-November resulted in poor germination. In natural conditions, seeds took about 4-5 months to germinate. Stratification of seeds for 15 or 30 days resulted in enhanced germination percentage as well as shorter mean time to germination (M.T.G.). In the laboratory,the seedlings grown in pure sand medium showed hyper-elongation due to etiolation but survived transplanting in polypots, following hardening in a shaded place for a couple of days. There was no significant effect of stratification on seedlings growth. A. indica seeds required a brief period of chilling and subsequent higher temperature during incubation for accelerating the germination and seedling growth.- Non-forestry Technology for Forest Based Wasteland Development

The importance of shrubs in reclaiming the eroded slopes of Himalayas and Siwaliks has been discussed. Since it is being increasingly felt that in such barren and degraded areas before planting trees shrubs should be encouraged to grow to retain soil moisture and to improve the site conditions. The growing techniques of most of the shrubs species have not been studied before in India. The Silviculture Division of this Institute for the past few years has done some prliminary work on the silvicultural aspects such as nursery and planting techniques and seed processing and germination. The paper presents a review of such work done in the division in the recent past.- Fruit Maturity And Interrelated Effects of Temperature and Container on Longevity of Neem (Azadirachta indica) Seeds

Fruits of neem were collected at different intervals of maturity. Physiologically mature seeds with maximum germination capacity and longevity were obtained 10 to 12 weeks after flowering (late July to early August) when some of the fruits turned yellow and started falling on the ground. This period coincided with peak green weight, size and a fully grown embryo enclosed in bard fibrous endocarp. Seeds were also stored at room temperature, 15°C and 5°C in sealed polythene bags, perforated polythene bags, perforated cardboard boxes (seeds wrapped in blotters) and over silica gel in desiccators. It was found that sealed containers and low temperature (5°C) are responsible for rapid deterioration of seeds while well aerated containers inhibited deterioration upto certain extent at room temperature and 15°C till 6 months.- Problems of Sal Forests - an Analysis

Vast tracts of forests are destroyed every year due to forest fires in India. Fire not only eliminates the regeneration of important tree species, but also causes serious damage to the site conditions, habitat of wildlife and thus to overall ecological structure of the forest. In this paper, studies made to find out the detrimental effects of fire on the ground vegetation in the West Dehra Dun Forest Division are described. The studies were carried out in the burnt and adjacent unburnt area of natural Sal forest of Asarori Range, Chandrabani Block -I. Relative frequency, relative density and relative dominance and Importance Value Index (Ivl) of different forest tree species as well as of ground vegetation were determined. The studies reveal tbat the regeneration of Sal and its associates such as Mallotus philippensis is considerably reduced and species such as Bauhinia variegala, Bombax ceiba, Pterospermum acerifolium and Melia azadirachta etc. were completely eliminated. The herbs and shrubs, however, showed increase in the relative frequency, relative density and relative dominance in burnt area. Some species like Flemingia pulchella, Phyllanthus urinaria, Bauhinia vahlii, Tylophora species etc. which are eaten by wild animals have shown increase in burnt site and this can be used as management tool in National parks and Sancturies for Range Management in Wildlife.- Socio-economic Factors Associated with Fuel Consumption in Rural Areas (VILL.

An attempt has been made in this study to assess the contribution of socio-economic factors (viz. occupation, family size, annual income, land holding and cattle) in determining domestic fuel consumption in rural areas. Fuel consumption is divided in two categories according to use of alternative sources of energy. To find the significance of socio-economic factors in determining the quantity of fuel consumption, the two characters (i) total fuel consumption and (ii) per capita fuel consumption have been analysed. Satistical results show that relationships between fuel consumption with each factor are significant when alternative sources of energy are used while for the second category without alternative sources of energy only family size shows the significant relationship with fuel consumption. Per capita fuel consumption is low when alternative sources of energy are used. Enhanced use of alternative sources of energy can balance the increasing demand of fuel wood and make use of fuel more economic.- Production Projections for Panel Products

The main object of this study is to estimate future production and raw material requirement for panel products. Multiple regression equation of the form Y = a + b1 x1 + b2 x3 where Y is production of the panel product x1 and x2 are the explanatory variables viz population and price indices respectively. On the basis of the predicted values of the production, future raw material requirement are estimated. The average annual growth of production for plywood, particle board and fibre board is in decreasing order. The industries have great export potential, but their export decreased after 1976 and became constant after 1979 probably due to cheaper supply from other countries or due to poor quality of our products. So it may be suggested that due consideration should be given to fulfil the raw material requirement at cheaper rates and the technology should be developed to improve the quality of the product.- Forest Production in India Vis-a-vis other Asian Countries
