Abstract: Fodder trees in agro-forestry system are planted to overcome the effects of the seasonal shortages or to insure against risks of drought and also to deliver benefits such as shelter, soil conservation, timber and fuel wood. An attempt was made to investigate the performance of fodder trees in the presence and absence of crops. The data pertaining to growth parameters and biomass parameters of the four fodder trees from an agro-forestry experiment for six years (1999-2005) was analyzed. Contrast analysis has been performed to study the performance of the different tree species with and without crops. The combined analysis of the tree data over the years was also performed.

Abstract: Soil organic carbon was estimated in four land uses viz. forests, plantations, agroforestry and horitculture in Haridwar district. Over all 425 soil samples were collected from different land uses at various locations. Soil organic carbon, bulk density and coarse fragments were estimated in collected samples and SOC pool was calculated by using the equation as suggested by IPCC Good Practice Guidance for LULUCF. Maximum SOC pool (73.63 t/ha) was estimated under sal forest followed by miscellneous forest (56.48 t/ha). Under horticulture land use, SOC pool was higher (58.66 t/ha) in the soils under litchi orchard as compared to Mango orchard (40.62 t/ha) and Guava (29.46 t/ha) orchard. Under block plantation, maximum SOC pool was estimated in the soils under teak (52.50 t/ha) followed by eucalyptus (39.06 t/ha), poplar (30.45 t/ha) and the least was under shisham (28.12 t/ha). Under agro-forestry model, poplar-sugarcane showed higher SOC pool (25. 78 t/ha) as compared to poplar -wheat (22.93 t/ha). On an average Haridwar ' s forests have 65.05 t/ha SOC pool while horticultural land use have 42.91 t/ha, plantation have 37.53 t/ha and agro-forestry have 24.35 t/ha. Soils under forests stand show higher carbon pool than other land uses. Average SOC pool under forests was 65.05 t/ha, therefore, Haridwar district has 4.09 million ton of SOC pool under forests.

Keywords: Bamboos, preservation, chemical , methods, insects
Abstract: Bamboos suffer from low shelf life because of attacks by fungi or insects mainly insect borers or termites. Traditionally, freshly cut bamboo poles were dipped in flowing water to remove starch, which attracts insects and pests or coating with oils or paint and even coal tar. The chemical method includes dipping in CuSO4, Boric acid, Borax and Sodium pentachlorophenate solution to be used either singly or in combination. However, forcing out the sap under pressure and replacing with chemicals such as Copper-Chroma-Boric acid is a better method for enhanced shelf life. For small pieces, a treatment with hot and cold solutions of urea and Boric acid for varying periods has also been found quite useful.

Abstract: The effect of errors in visual assessment of distance to objects, on density estimate obtained through line transect sampling was investigated. An ex situ trial was conducted to assess the agreement between actual distance and visual estimates made by the observers. Wooden poles were fixed at known distances in random sequences on a flat ground and volunteers were asked to estimate the distance by visual observation. Linear regression equation fitted through the origin showed that there was underestimation by 2 m for every 100 m of actual distance, which is negligible. The mean bias in the visual estimation of actual distance was not significantly different from zero. However, the coefficient of variation of visual estimates of distance varied from 54 percent in 0-20 m class to 34 percent in 80-100 m class. An examination of the theory of line transect sampling showed that for a given set of detections, overestimation of distances in the field would lead to underestimation of density and vice versa. Increasing disruption of random nature in distance measurements was found to bring down the density estimate on an average for a fixed set of detections and transect length.

Abstract: Effectiveness of finger jointing was assessed in utilising lower quality mango wood which is extensively used by handicrafts industries in India. The study was based on the estimation of Modulus of elasticity (MOE) and Modulus of Rupture (MOR) under static bending of finger jointed sections and comparing them with the values measured for clear wood sections from the same lot. It was found that the MOE of the sections joined by urea Formaldeyhyde adhesive showed significantly better values than that of even unjointed sections. The MOR values of such jointed sections were similar to those of unjointed clear wood sections. Sections jointed throught Polyvinyl Acetate adhesive exhibited lower MOR and MOE values.

Abstract: The investigation was carried out in the Solan Forest Division (900 m to 2100 m amsl) of Himachal Pradesh to determine the site factors influencing the forest growing stock (FGS) and to develop growth prediction model functions. All site factors i.e. temperature, slope, aspect, soil depth, soil organic carbon, and bulk density were significantly responsible to influence the FGS. The FGS decreased with decrease in temperate along altitudinal gradient from 900 m to 1900 m indicating a positive effect of temperature on the volume of the Forest Growing Stock. The south facing slopes experienced lower FGS as compared to north facing slopes. The gentle slopes had higher FGS as compared to steep slopes. The FGS was also influenced by soil factors which was higher on sites having higher soil depth and soil rich in organic carbon whereas, bulk density showed a reverse trend. Among site factors, the temperature, aspect and soil depth were the major factors that influenced the FGS. The step wise multiple linear regression analysis demonstrated that contribution of the different site factors to teh FGS in descending order were as as temperature > aspect > soil depth > organic carbon > Bulk density > Slope and among various model functions, the model incorporating temperature, aspect, soil depth and organic carbon were the best fit for the estimation of FGS. Finally, to the scope of future work, the models developed be further tested and validated for a large number of sites.

Abstract: Rates at which CO2 is being sequestered in two different forest types of Himalaya was computed. For comparative study degraded and non-degraded sites of pine and oak forests in Kumaun Central Himalaya were selected. The Van Panchayats (VPs) or community forests are managing the non-degraded forest sites for centuries. It was found that the sequestration of CO2 in non-degraded forests is significantly greater than the degraded forests. On the basis of present study significance of community forests in both Uttarakhand and the world is recommended and advocated to fight against the global warming as forests ulitmately become the sink for increased CO2 worldwide. The ' carbon trading ' will indeed evolve as the panacea the war agaisnt global warming.

Abstract: There was a wide variability in the levels of awareness about eco-tourism among the tourists, the local villagers and the forest officials. Of the two components, viz., enviornmental and soical welfare, the letter was not understood by many. While nature, wildlife and its products were the aesthetic needs of tourists, the indigenous values formed a part of their recreation, physical and mental relaxation. Locally available services like guidance, hospitality, asset maintenance, product sales, etc helped in meeting these needs. This resulted in overall improvement in the quality of life. Better promotion and training strategies with adequate planning and ensured local cooperation were the prerequisites to bring the dual effects on forest conservation and community development.

Abstract: Andaman and Nicobar Islands being close to the equator; enjoy tropical humid climate condition, which are much congenial for vegetative and reproductive growth of Morinda citrifolia. Eighty species of Morinda have been reported globally of which, twelve species from different parts of India and three known species found to be in Andaman and Nicobar Islands. Great variability within the species is the common occurrence. Owing to its high nutritive value, medicinal importance and having national and international market, there is a possibility for emerging as one of the most remunerative fruit crop to the island farmers. It flowers and fruiting occurs round the year. Noni plant is distributed in almost all parts of the island. It can be found near the coast, in open lands, and grass lands, in gluches and distributed forest of the dryer areas. It tolerates high soil salinity and brackish water stagnation, therefore, the Morinda citrifolia, is the best choice for planting in these affected lands. Farmers are showing much interest in Noni cultivation because of assured income from this plantation. Therefore, studies on its diversity have to be critically examined for various uses from the different tropical parts of the country.
