This paper contains a review of scientific information in tbe field of forest fertilization based on the recent research in forest nutrition, nutrient cycling and fluxes of nutrients in the forest. The information is discussed in the context of application in a tropical country like India. There is immense potential for application of fertilizers In the forest plantations, specially conifers, Eucalyptus and nutrient poor soils. Social forestry, agroforestry and farm forestry; with a view to increase the productivity of the forests and ensure adequate fiscal return on long term sustained basis. Further the maintenance of the environment and future supply of forest products is linked with efficient management of the existing forest resources, and to achieve this all out efforts should be made to enhance the productivity of the forest plantations in India. In Ihis context the potential application of fertilizers in Indian condition is discussed. There is considerable scope to Increase tbe production through application of fertilizers, but to obtain clear idea it is recommended to carry out longterm field trials.- Seed Germination Behaviour of Desmodium tiliaefolium G.

The task of improving the productivity from the forests and their protection and extension on degraded areas have acquired national priority in India today. A sound research base is essential for the efficient management of the forests and to develop innovative approaches in their better management for higher productivity. Realising this the Central Government had established an Indian Council of Forestry Research and Education (ICFRE) to oversee and co-ordinate the research work in the country. Five new Institutes have also been opened at Jabalpur, Jodhpur, Jorhat, Bangalore and Coimbatore. There is need at the national level to develop a system oriented planning framework for better resource allocation, control, monitoring and execution of research work. This paper deals with these issues and gives a framework for planning forestry research in India.- Leaf Litter Decomposition and Nutrient Release in Shorea robusta and Eucalyptus camaldulensis Plantation

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.- Growth Performance of Dalbergia sissoo, Eucalyptus grandis, Michelia champaca, Grevillea robusta, Bauhinia variegatra and Bauhinia purpurea for Planting under Social Forestry Programmes

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.- Studies on the Performance of Phillipines and Malaysian Provenances of Albizia falcataria (L.)

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.- Studies on the Performance of Existing Logging Tools of Southern India, their Maintenance and Improvements for better Efficiency

Tropical rain forests in India are climatic climax of a region covering fairly extensive areas in the Western Ghats, North-eastern India and Andaman and Nicobar islands These forests, dynamic but fragile, are fast disappearing on account of biotic interferences and poor management. This paper deals with the probable research areas, to develop a sound scientific managemeni base for these Forests. Research should be carried out in such a manner that ecology, silviculture and management, are blended judiciously in dealing with rain forest. Studies on the structure and distribution of these forests in different geological, climatic and geographical zones typological studies for earmarking clearly types and sub-types, auto-ecological and syn-ecological, quantitative ecological and ecosystem modelling are discussed. The either research areas, identified, are in the field of genetics, silviculture, wood sciences. Logging, Wildlife, Pests and diseases, watershed management, develorment of trihologically viable socio-economic packages intergrating various fields of developmental activities, for setting the tribals, practising shifting cultivation.- Sucessive Improvement in the Wood Harvesting Technology in India

Forests are the most important natural resources available at the disposal of Man. The harvesting of the Forest products is an age old phenomenon and as back as 2000 B.C., The Indian timber was exported to the western and arabic countries. The logging tools prevalent in India were primitive and less productive, resulting in colossal loss of most valuable timber. In India, even after introduction of scientific management of Forests, principles of Silvicultural science took precedence over all other forestry activities and improved logging was not yet on the priority. In 1852, for the first time, attempts were made to replace the axe with the saw for felling and conversion. The demand of timber increased steeply after the second World War and need was felt to extract the timber from the inaccessible hilly areas. With the introduction of Truck transportation and roads and Bridge construction the timber harvesting operation, were revolutionized in the plains. After Independence, the demand further increased on account of population pressure and development and since then the demand of timber is always increasing. With this demand, need was felt to improve the logging practices and F.A.O. Expert Mr. A. Huber visited India during 1951-53. Another F.A.O. Expert Mr. A. Koroleff also visited India in 1951, on the recommendations of these experts, Logging Branch was established in 1951 in FRI for conducting research and imparting training in basic logging to the Foresters and forestry workers. After achieving initial Breakthrough, the need was felt to separate training from the research, which led to the establishment of Logging Training centre Project in 1965, with H.Q. at Dehra Dun and Four Regional Centre. The centre has since acquired the states of Logging Development Institute. The major achievements of the research carried out by the Logging Branch are in the field of work and cost studies, Survey and improvements of logging tools, Design and fabrication of logging tools suitable to Indian condition such as FRI yarder (long distance skyline crane), various, types, of winches and improvements in the saws and wotk physiological studies. In future emphasis should be laid on research on the Ergonomic aspects, to devise suitable tools and equipments for logging operations which are economically viable, can work in our conditons and which are acceptable to the workers. Transportation studies should also be carried out. There should be close link between the Silvicuitural prescriptions and Logging operation.- Contribution of Joint Forest Management in Conservation of Forests, Climate Change and Poverty Reduction

This study documents the impact of Joint Forest Management (JFM) on forest conservation and poverty reduction. The JFM was developed as a response to forest degradation and its impact on the ecology and livelihoods of poor people dependent on forests. The JFM performance in the study area resulted not only to better access in the forests and livelihoods but also augmentation in the local economy. With increased income, literacy rate went up significantly whereas out-migration reduced. There was significant improvement in the regeneration of forests and the biodiversity. The better moisture and soil conservation resulted in increased water table which led to better irrigation facilities for the adjoining agriculture field leading to increased agriculture yield. The poverty stricken villages changed into prosper villages.Keywords

This article reviews policy and institutional framework set up for implementation of Joint Forest Management Programme in India. Initially, the growth of JFM was tardy and slow during first initial decade due to lack of proper institutional arrangements. The MoEF revised JFM guidelines in 2000 and 2002 and circulated these guidelines among all States and Union Territories with sharpen focus on extending JFM programme to good forests with very well defined institutional and legal framework. Consequently, JFM movement in the country progressed both quantitatively as well as qualitatively. As of 2007, more than one lakh JFMCs had been managing around 22 million ha of forestland. Out of 1.6 million reported forest fringe villages in the country, roughly 62% forest fringe villages have been covered under JFM stream with involvement of around 8.3 million families and 62 million people.Keywords

An attempt has been made in this paper to estimate the economic value of the goods and services provided by the forests of the country. The total economic value has been estimated at 6.96 lakh crore annually, which is approximately 6.86% of the GDP and represents the bare minimum approximate values of goods and services generated by forests. Valuation of certain services such as waste treatment, biodiversity, cultural and traditional values of trees and forests could not be assessed due to lack of proper methodologies; therefore the total value may be even higher than what has been projected in this paper.Keywords

Integrated land development model adopted in 10 forest fringe villages in tribal dominated areas of Jharkhand under a UNDP sponsored project has achieved remarkable success in sustainable livelihood promotion and conservation of natural resources, checking migration of rural mass to outside state for employment and disassociating young people from Maoist and naxal activities. The rural folk revived the traditional practice of lac cultivation with scientific and technical support of the Institute to reap substantial benefits in tune of 70,000-90,000 per family annually. Apart from growing lac on its well known host trees such as palash, kusum and ber, initiative has been taken on large scale lac cultivation on new host plant Flemingia semialta in farmers' fields. The intervention reduces the gestation period to 1 year and facilitates intensive management for enhanced crop yield.Keywords
