The vegetative propagation of Dendrocalamus strictus, D. membranaceus, D. hamiltonii, Bambusa tulda and B. bambos through seedlings proliferation have been studied by raising the seedlings in nursery beds with a view to reduce the nursery period to obtain massive production of tiller/rhizomes in a single phase of separation of seedlings. The results indicated that by separation of saplings through macro-proliferation after a span period of four months approximately four times of culms (tillers) and five times of rhizomes are produced in Dendrocalamus strictus, D. membranaceus, D. hamiltonii and Bambusa tulda from mother stock. The performance of Bambusa bambos is even better (5 times of culms and 6 times of rhizomes per sapling were obtained) by raising the seedlings in nursery bed by adopting better nursery practices.- Nursery Technique of Quercus leucotrichophora : Standardization of Proper Method of Seed Sowing and Optimum Irrigation Schedule under Dehradun Climatic Conditions

The paper presents the results of the investigations carried out for determining of best combination of method of seeds sowing and optimum irrigation schedule for the production of maximum healthy seedlings of Quercus leucotrichophora (Syn. Q. incana). The results of the experiment indicate that irrigation twice a day (morning and evening) and dibbling or line sowing method take significantly lesser time for germination of seeds and results in higher germination and plant per cent and healthy growth rate of seedlings of this species. Dibbling method of sowing and irrigation twice a day proved to be the best combination.- Determination of Proper Depth of Seed Sowing in Michelia champaca in Nursery

Acacia mangium has high potential for use in commercial plantations in the tropics and is widely used in some countries for soil conservation, sand stabilization, dune fixation and other economic products. This paper deals with the results of an experiment carried out by the Silviculture Division, Forest Research Institute, Dehra Dun for the best combination of the ratio of soil mixture and optimum depth of sowing the seeds. The results indicated that the soil mixture should be 2 : 1 (soil: sand) and seeds should be sown at the depth of 1.0 em. Farmyard manure use may be added after transplanting the seedlings in the ratio of 2 : 1 : 1 (Soil: sand: F.Y.M.).- Agathis robusta (australian Dammer Pine, Kauri Pine) - its Successful Trials and Introduction at New Forest Dehra Dun

Investigations were carried out to study the effect of orientation and different ratio of soil mixture on germination behaviour of Quercus serrata seed in nursery. Three position of seed sowing I e, vertical (embryonic end upward and downward) and horizontal. Seeds were sown in four different ratios of soil mixture. Experiment coducted revealed that Quercus serrata seedlings could be raised by sowing the seeds in horizontal position in the soil mixture consisting of soil, sand aDd farmyard manure in 2:1:1 ratio in perforated polythene bags or in nursery beds for better germination.- Study of Effective Insecticide/Fungicide to Protect Seed of Michelia champaca Linn. for Getting Higher Germination in the Nursery

Acacia auriculiformis seedlings were raised in different soil media in different containers. The results of this investigation revealed that the seedlings could be raised in either nursery beds or wooden boxes by dibbling the seeds at 1 cm depth or by direct sowing in polybags. The soil media (soil and sand) should be in 2:1 ratio. Farm Yard Manure could be added later on at transplanting stage for better growth of the seedlings.- Infroduction Trials on Acacia caven at Nursery Stage Germination Behaviour and Growth of the Seedlings under Dehra Dun Conditions

Neem (Azadirachta indica) is a very important, multipurpose tree species of drier region of this country. In its growth on poor and hardy soil, it is versatile and hence an excellent species for planting wastelands, and for social forestry. This paper deal with the results of an experiment carried out in the nursery of Silviculture Branch for determining the best combination of method of sowing and optimum depth of solving and quantity of seeds for afforestation purposes. The results indicated that line sowing and broadcasting are equally effective. The seedling must be protected from frost.- Studies on Nursery Techniques (Method of Sowing and Optimum Irrigation) of Albizia lebbek (L) Benth under North Indian Moist Tropical Climatic Conditions

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.- Fire Break Maintenance in India-a Preliminary Study on Efficiency, Suitability and Economics of the Back-pack Blower (Model KWH 66L) and Power Blade Fire Rake
