Abstract: The present study was undertakne to assess the effect of different concentrations of gibberellic acid treatment on germination and seedling growth behaviour value in Albizzia lebbeck, Acacia nilotica and Prosopis cineraria. The results of the study clearly indicated that the seed germination and growth rate hastened to maximum by the application of 750 ppm GA3 for 24 hrs, indicated thereby that as the concentration increased, growth behaviour increases. The maximum growth attributes value was obtained at 750 ppm in Acacia nilotica.

Abstract: Vitex altissima L., a threatened tree species with high conservation value in the Western Ghats of India, has low germination rates, hindering the restoration of this species. In addition to studying the drupe characteristics of V. altissima, various pre-treatments were conducted to enhance the seed germiantion rates. The treatments included alternate wetting and drying, soaking in GA3 solution and fire. The number of days for initiation and completion of germination varied from 10 to 16 and 74 to 93 respectively. Overnight soaking of the drupes in 300 ppm GA3 solution increased the germination percent, mean daily germination, peak value and germination value by 280 percent, 260 percent, 311 percent 1416 percent compared to the control. This was closely followed by GA3 solution 200 ppm soak overnight and 300 ppm soak for 30 min., alternate wetting and drying of drupes for ten dyas and straw fire treatment.

Abstract: The rooting response of hardwood cuttings of Seabuckthorn (Hippophae rhamnoides) treated with auxins was studied during 2008-2009 to standardize the vegetative propagation. The effect of rooting hormones was observed for number of shoots, and roots, maximum length of primary root and rooting percentage. The results indicated that the dip application of 300 ppm IBA for 48 hours was optimum for treating the hardwood cuttings of Hippophae rhamnoides taken in March and will be beneficial for its successful propagation and cultivation under Ladakh Himalaya conditions.

Abstract: A study was made to compare th 11/2 years performance of seedlings belonging to Easter Gulf (EG), East central (EC) and Southeast Atlantic (SA) sub-regions of South-eastern USA. The collar diameters were in the order of SA>EG>EC. Variation among stands was significant for collar diameter and number of branches per metre of stem length. About 14700 seedlings belonging to 66 control-pollinated families and 5000 seedlings belonging to 20 open-pollinated families have been produced. Selection and cloning of promising genotypes was done. Testing of clones is in progress.

Abstract: In this study, soil organic carbon (SOC) stock and soil characteristics were measured in mixed oak and mixed pine forest for two years (2008-10) at different altitudes of Kumaon Himalaya. The study revealed that soil texture at selected sites varied from loam to sandy loam and soil pH ranged from slightly acidic to neutral. The SOC stock was found to be higher in mixed oak forests than mixed pine forests. The average SOC stock ranged from 110.37 to 125.03 ton/ha at non-degraded mixed oak forest site and 43.81 to 53.47 ton/ha at degraded mixed pine forest site. P2O5, K2O, TN and C:N ratio were also found to be higher in mixed oak forest than mixed pine forest.

Abstract: The investigation undertaken to find out the rate of decomposition of leaf litter of seven multi-purpose tree species, viz., Tectona grandis, Eucalyptus tereticornis, Dendrocalamus strictus, Terminalia bellirica, Cassia fistula, Casuarina equisetifolia and Terminalia arjuna for 195 days i.e. from first fortnight of July 2009 to second fortnight of January 2010. The litter bag of nylon net (1mm mesh size), 20 x 20 cm. in size, containing 10 g air-dried samples were incubated on surface in the first week of July 2009. Litter bags of each species were placed on the plantation field of respective species. For each species 3 litter bags were recovered at fortnight intervals for the the study of weight loss in dry matter due to decomposition. Fresh leaf litter were also chemically analysed for N, P and K using standard perscribed procedure. Significantly the highest amount of nitrogen release (%) was recorded in Eucalyptus tereticornis which was followed by Dendrocalamus strictus. Among different multipurpose tree species the maximum amount of phosphorus release was recorded in Cassia fistula and maximum amount of potassium release percentage was in Eucalyptus tereticornis which was at par with Terminalia bellirica.

Abstract: A study was carried out to know the floristic diversity along an altitudinal gradient with elevation varying from 3000 m to 5000 m above msl in Namgia valley falling in cold desert area of district Kinnaur, Himachal Pradesh during 2007. Total number of plant species was 142 belonging to 49 families and 105 genera. The dominant families were Asteraceae, Polygonaceae, Ranunculaceae and Rosaceae. The number of tree species at 3000-3500m elevation was 8 with the dominance of Populus nigra. The number of shrub species were 17, 8, 6 and 2 at the elevation of 3000-3500m, 3500- 4000m, 4000-4500 m and 4500-5000m respectiely while number of herb species were 72, 62, 42 and 32 species at the same elevations. Juniperus communis taking shape of dominant shrub at 3500-4000m and 4000-4500 m elevations. Ephedra gerardiana was dominated herb at 3000-3500 m and 3500-4000m elevations. The distribution pattern of most of the plant species was contiguous in all altitudes. Index of diversity for herb species at different elevations ranges was 3.56, 3.25, 3.14 and 3.04. Out of 64 medicinal plant species recorded from the area, 13 species fall in the threatened catergory.

Abstract: The forest dwellers depend upon forest for meeting their livelihood requirements including fire wood, timber and other minor forest produce. But due to shrinking natural-resources and commercialization of forest products for urban utilization, forest fringe community is deprived of natural-resources which led them to frustration and anger. These have got manifested in the form of violence and unlawful activities by a section of forest dwellers. Scheduled Tribe and other Traditional Forest Dwellers (Recognition of forest rights) Act 2006 was enacted to address these issues. Tripura state under the 6th schedule of the constitution has established the Tripura Tribal Area Autonomous District and empowered the fringe forest communities to govern themselves and to protect and preserve their culture, customs and traditions. Present article described the various steps taken by the Tripura Government to address various issues for the welfare of forest dwellers for creating " Win-Win" situation.
