The paper discusses the problems of plant diversity conservation under the present forest management systems. Besides establishing protected areas, need for reorienting management of other forests for plant diversity conservation is stressed. Peoples participation is necessary for plant diversity conservation in the forest irrespective of their degree of degradation. Suggestion is made to extend participatory management to non-degraded forests also for sustainable production and utilization of non-timber forest products.- Effect of Root Pruning of the Growth of Transplanted Silver Fir Seedlings

Of the four variables studied' viz' diameter at broast height' age of wood' radial annual growth rate and relative position of breast height sample point' the age of wood was found to be the most efficient predictor variable for estimating breast height specific gravity in plantation grown chir pine trees. In multiple regression analyses' no other factor significantly affected the specific gravity in the presence of the age of wood. Thus' breast height specific gravity in plantation-grown chir pine trees can be estimated with reasonable accuracy with the help of the age of wood at breast height.- Cuttings Taken from Bottom One-third Part of Populus Ciliata Plants Perform Better

Studies on seed dispersal were carried out in a mixed forest of sliver fir and spruce in Kotgarh Forest Division, Himachal Pradesh. The number of seeds dispersed per square metre of forest floor area in case of sliver fir and spruce varied from 51.9 to 528.6 and 9.2 to 65.8 respectively. The peak dispersal period for sliver fir was from 13th to 24th November when 85.84 per cent of the total seed (by weight) was dispersed while the same for spruce was from 27th October to 1st December during which period 84.50 per cent of the total seed (by weight) was dispersed. In case of sliver fir the seed dispersed after 13th October to 10th November was slightly 5 heavier than that dispersed in other weeks and there was no such difference discernible in cas of spruce.- Seed Dispersal, Seed Germination and Seedling Establishment in Natural Forests of Silver Fir and Spruce II.

Studies conducted on seed germination and seedling establishment in natural forests of spruce and sliver fir in Kotgarh Forest Division, Himachal Pradesh showed that in case of both spruce and silver fir the seed dispersed in October had lower germination percentage than that dispersed in November. Silver fir seed started germinating just after the snow melt in May and spruce seed germinated with the onset of monsoon rains in the later part of June. The percentage of seedlings at the end of first growing season to the number of seeds dispersed in case of silver fir and spruce varied from 0.72 to 7.99 and 1.21 to 8.17 respectively. The mortality percentage of the seedling in sliver fir and spruce varied from 31.93 to 80.58 and 22.22 to 100 respectively in different plots.- Effects of Nursery Density on Seedling Characteristics of Silver Fir (Abies pindrow Spach)

Hazard reduction for fire prevention in forest areas can be achieved by reducing the quantity, breaking the continuity and disturbing the arrangement of forest fuels. Factors affecting the build-up of fire hazard have been described and an over-view of the possible techniques of hazard reduction in Indian forests has been presented. It has been concluded that properly maintained fire-lines can help in breaking the continuity of the fuels but they cannot he relied upon to contain and localise the fires by themselves. Planting of fire resistant species in covered firebreaks holds greater promise and such species need to be identified for different areas. Silviculural practices like weeding, cleaning, thinning etc. and agri-silvicultral practices can help considerably in reducing fire hazard. Need for refining the technique of prescribed burning through research on fire behaviour under variable conditions, thorough training of personnel and close supervision of the operation has been stressed.- Distribution and Growth of Weeds as Influenced by Intensity of Felling in Spruce and Silver Fir Forests

The results of a study on the distribution and growth of weeds in spruce and silver fir forests worked under selection, shelter-wood uniform and clear-cutting systems are presented. The composition and relative dominance of weeds changed with the iutensity of fellings. The density and growth of weeds was the least in selection rorests and the highest in areas worked under clear-cutting system; areas worked under shelter-wood uniform system were intermediate in this respect. Total weed biomass. In clear-cut areas was 4 and 2.4 times that in those worked under selection and shelter-wood uniform systems respectively. Most of the weeds whose growth is encouralled by heavier felllngs grow tall and luxuriant and are harmful to the regeneration of spruce and silver fir.- Preliminary Studies on the Quality of Spruce and Silver Fir Seed as affected by its Source

The struggle to obtain fuelwood for cooking food is the real energy crisis in rural India as the problems connected with increased use of soft coke' kerosene oil' vegetable wastes' dung cakes and gobar gas leave only the fuelwood to be increasingly depended upon to supply energy to rural population. Anticipated demand ror fuelwood far exceeds the expected supply. Energy plantations to be raised by forest department on forest areas' village waste lands and panchayat lands may not alone solve the problem in view of resources constraints' and difficulties in establishment and management or such plantations and also in transport and sale of fuelwood to rural populatin scattered in villages not always served by roads. Farm Forestry to be practised by villagers' thus' appears be a more practical proposition to solve energy crisis in rural areas,- Economics of Chir Pine Seed Collection

This paper discusses the implications involved in the change of silvicultural system from Selection System to Concentrated Regeneration Fellings amounting to almost clear felling under Uniform System for the management of silver fir forests. The silvicutural requirements of silver fir have been discussed and keeping the same in view the advantages and necessity of maintaining irregular stand structure are stressed. The experience of working some silver fir areas of Himachal Pradesh under Concentrated Regeneration Fellings suggests that such heavy fellings adversely affect the site and the establishment of silver fir plantations. From silvicultural stand-point the choice for a suitable silvicultural system for the management of silver fir forests may lie between Indian Irregular Shelterwood System, Group Selection System and Strip System depending upon the terrain, crop composition and other relevant factors. Present state of knowledge is not sufficient to categorically recommend a particular silvicultural system for the management of silver fir forests growing under different conditions and the need for extensive research to evolve a suitable silvicultural system for the management of these forests is stressed.- Himalayan Conifers as Important Source of Raw Material for Pulp and Paper Industry

The raw material requiremtents of pulp and paper industry are expected to increase considerably in the near future. Adequate supply of long-fibred pulp wood is very necessary for the future expansion of pulp and paper industry as the utilisation of hardwoods potential is linked with the availability of long-fibred raw material. Long-fibred raw material is provided by the coniferous forests of Himalayas and the bamboo forests in many parts of the Country. This paper pleads for treating the Himalayan conifers as an important source of raw material for the pUlp and paper industry rather than relegating them as inaccessible and outside the limits of economic exploitation. It has also been brought out that conifers are capable of giving higher yield per unit area than bamboos and should therefore, be regarded as more important source of long-fibred raw material than bamboos.- Raising of Chir (Pinus roxburghii) Plantations in Himachal Pradesh

Agriculture in hills is dependent on forests in many way and its development is very intimately linked with conservation and proper management of forests. Forests protect hill sides and agricultural fields, ensure perpetual of water in streams and rivers for irrigation and power generation, mitigate the rigours of climate and thus help in increasing agricultural production, help in maintaining ecological balance, augment supplies of fodder for cattle, supply fuel wood to release cowdung as manure, make available litter to be used as manure and meet the requirement of wood for agricultural implements. Forestry operations supplement the income of the farmers and provide money for the purchase of neccessary inputs for agriculture. Wood for making packing cases to pack fruits and vegetables is made available from forests. Agriculture in bills call not prosper in the absence of proper conservation and management of Forests.- Management of Fir Forests Through the Century

The results of two experiments conducted to study the effect of the depth of sowing on germination of spruce seeds are summarised. In both these experiments the germination percentage decreased as the depth of sowing increased; the decrease being very much marked with sowings done at a depth of 15 mm and more. Deeper sowings delayed germination and the number of days taken for the commencement of germination increased with an increase in the depth of sowing. The results of these experiments show that spruce should be sown as shallow as possible and in no case deeper than to 10 mm.- Comparative Study of the Techniques of Raising Deodar (Cedrus Deodara) Plantations in Himachal Pradesh
