Keywords: Non Timber Forest Products, Women, Family traits, Income.
Abstract: The role of women in collection, processing, consumption and trade of NTFPs is very crucial as it contributes directly to the family income. The present research was conducted in Karnataka state of India during the years 2004-06 with the objective to analyse the relationship between socio-economic characters of the families and the type of NTFP activities done by the families. Maximum percentage of families involved in NTFP activities belong to the scheduled caste and tribe families and were having nuclear family system. They lived in kuchha tile roofed houses and did not own any agricultural land. About 22 different types of NTFPs were collected by the inhabitants. Maximum percentage of women collect muttal leaf followed by fuel wood, fodder grass and jamun fruits. An average of 5 hours per day and 35.51 days per year were spent for NTFP collection activities and a distance of 8.85 kms per day was travelled by women for NTFP activities. Highly significant and positive correlation was observed between the number of female respondents and total number of NTFPs collected and the income from NTFPs. Where as highly significant and negative relationship between total agricultural land and NTFP collection days, total time spent per day, average distance travelled for NTFP collection and total quality of NTFPs collected was observed.

Abstract: To explore the genetic diversity in Persian walnut (Juglans regia L.) trees in Shimla (Himachal Pradesh). 212 unevenly managed trees were screened for yield and biomass contributing characters. Maximum values of coefficients of variability were recorded for nut yield (68.42%) followed by yield efficiency (66.01%). Based on nut yield, trunk and leaf characteristics the intra-specific variability was assessed using non-hierarchical Euclidean cluster analysis. All genotypes were grouped into eight clusters showing non-parallelism between geographic and genetic diversity. Genotypes of cluster 1 and 8 were highly diverse from each other having inter-cluster distance of 28.30. The mean values of trunk cross-sectional area (cm2) were higher (1262.06) and (1005.52) in genotypic clusters 1 and 5, respectively. Genotypes of cluster 3 recorded highest nut yield (27.32 kg/tree) and were selected for their further evaluation in agroforestry systems.

Abstract: A study was carried out to generate the information on organic carbon stored in the soils of four land uses viz. Forests, Grassland, Barren Land and Agriculture in Jhalawar district of Rajasthan. Under Anogeissus pendula followed by Diospyros melanoxylon (9.99 t/ha), Lannea coromandelica (8.92 t/ha), Butea monosperma (8.81 t/ha), miscellaneous (8.74 t/ha), Tectona grandis (7.03 t/ha), and the least was under Terminalia arjuna (6.78 t/ha). Grass land site was situated on slope terrain and samples were collected from top of the slope and bottom of the slope. Higher SOC pool (6.13 t/ha) was observed at the bottom while on the top SOC pool was lesser (2.90 t/ha). SOC pool in the barren land of the Jhalawar district was 3.18 t/ha which is quite low. SOC pool under agriculture was 2.47 t/ha in the district. When SOC pool under all the land uses of Jhalawar district were integrated, it was observed that forests contribute the maximum share (47.12%) of the total SOC pool followed by grasslands (23.66%), barren land (16.65%), and the least was agriculture (12.57%).

Keywords: Carbon stock, Altitudinal gradient, Different forest cover, Darjeeling Himalayan region, West Bengal.
Abstract: Carbon stock in soils results from the balance between inputs and outputs of carbon within the below ground environment and the amount of soil organic carbon and its rate of decomposition varies with temperature and precipitation. Altitude is often included in the studies of climate variables on soil organic carbon dynamics. Present study was undertaken to assess the soil organic carbon stock along an altitudinal gradient from 155 to 3500 m amsl in Darjeeling Himalayan region only under foliage cover. Maximum soil organic carbon in the top soil layer (0-15 cm) was exhibited by sub-alpine/alpine and high altitude (2500-3500 m and 2000- 2500 m respectively) forest sites (59.8 and 58.2 g/kg respectively.) followed by mid-altitude (1500-2000 m) forest sites (46.1 g/kg), lower hill (1000-1500 m) forest sites (40.3 g/kg) and low altitude (500- 1000 m) forest site (35.8 g/kg). In the Tarai region (<500 m), the value was still less (26.9 g/kg). A decreasing trend in soil organic carbon was observed with increased soil depth.

Abstract: Chir pine needles are modified leaves from chir pine (Pinus roxbughii) trees, a major species in the temperate Himalayan forests. Under the present work, pine needles were used as raw material for making particle boards. Pine needle in its natural form is difficult to wet by resin. These problems were solved by cutting the needle into smaller sizes and bonding was improved by using specially made cardanol-phenol -formaldehyde resin. Glued and dried pine needles were drawn into mat and hot pressed to get panel products for various end uses. Process parameters varied to optimize strength properties of the products. Particle board made out pine needles conforms to all properties of wood particle Board as per IS: 3087 except MOR and MOE. Ceiling tiles of various designs were developed from glued pine needle as well as pulverized pine needle powder. Pine needle particle board (plain and design) was used as panel door infill and small tea-poy top to demonstrate the application potential.

Abstract: Ailanthus excels Roxb. (Simaroubaceae) is a lofty deciduous tree, widely distributed in the country. The seeds, being very light and winged, place early in the first rainy season after the fall of the seed: but the seedlings rarely survive due to the sensitiveness of the seedlings and their intolerance towards heavy need growth. In the present investigation, Germination experiments were conducted on seeds of Ailanthus excels sown in different growth substrates at varying depths. Germination percentage, germination energy and germination values were all greatest when seeds were sown at a depth of 0.5 cm depth and lowest when sown at 1.5 cm depth.

Abstract: Progressive farmers of Punjab and the adjoining states have adopted agroforestry intensively keeping in view its good economic returns by growing trees in conjunction with agricultural crops on field boundaries and as inter-culture with field crops. The present paper deals with the economics of growing Populus deltoids Bartr. Ex.-Marsh on farm lands in Punjab. The total area under poplar plantation in Punjab, mostly agroforestry, is estimated to be 75,000 ha and is steadily increasing. Poplar-based agroforestry in Punjab is economically viable and more profitable to the farmers than many other crop rotations. The bole biomass was found to vary with site, ranging from 19.8 t ha-1 at 8 years on average sites to 36.2 t ha-1 on excellent (site quality 1) sites. The biomass of branches, twigs, bark and roots would be in addition to these values.

Abstract: Paper presents morphological characterization of 64 half-sib progeny seedlings raised from seed collected from a single female Populus suaveolens Fisch. Tree growing in the vicinity of P. ciliate and two saplings one each of P. ciliate and P. suaveolens raised from stem cuttings. K-Means clustering of leaf and branch morphological traits of progeny seedlings resulted in forming two clusters each of them represented with a sapling each of P. ciliata and P.suaveolens. The 95.45% individual seedlings (62 in number) were clustered with P.suaveolens (female parent) and 4.55% (2 in number) with P. ciliata (male parent). Some traits like, number of glands at the base of leaf blade, pubescence on the lower surface of leaf blade and leaf tip in progeny seedlings were associated with male parent -P.ciliata and two progeny seedlings with these traits got clustered with this species, whereas, the remaining progeny seedlings had leaf and stem traits similar to female parent-P.suaveolens.

Keywords: Afforestation, Conservation, Forest cover change, Forest transition, Deforestation, Forest degradation, Policy implications.
Abstract: The shift from decrease to a trend of increasing forest cover associated with economic development of a nation or to a geographical region is referred to as forest transition. Studies indicate that earlier stage of human development is marked by high forest cover and low deforestation but increase in incomes accelerate the rate of deforestation leading to loss of forest cover; but at incomes beyond a certain level, the rate of deforestation reduces; then the trend reverses and a slow increase in forest cover is seen. Evidences of Indian forest transition were tried to be traced from the Land Use and Land Cover Change for the period 1880-1980. Supplementing this data with the recent forest cover data of FSI from 1990 onwards, an attempt has been made to characterize forest transition in India. Deforestation was the dominating aspect in the initial temporal phase (till 1980), large scale afforestation/rehabilitation, social forestry and agro-forestry programmes of the state and central governments dominated the temporal phase of forest transition in India during the period of 1980-2000. Conservation and sustainable management of forests dominated the later phase (Beyond 2000). Timber production from government forests gradually declined about 2 million m3 from the forests (excluding trees outside forests) in 2010 while most of the wood produced in the country come from trees outside forests (TOF) grown in private lands under agro-forestry, along the roads, canal, homesteads, etc. It ' s predicted that in a business as usual scenario, the forest transition in India will follow the trend as established in the last three decades and it is projected that the forest cover will increase to 71.34 million hectare in 2020. Forest transition trajectory in the forest transition curve indeed serves an easy instrument for testing the effectiveness of government interventions and policy implications.

Abstract: The screening of some insecticides viz. monocrotophos, chlorpyriphos, cypermethrin and imidacloprid was done to determine the LC50 values against Trichogramma chilonis. Imidacloprid was found most toxic to Trichogramma chilonis, at thirty minute, one, two and six hour after treatment with their lowest LC50 value of 0.07, 0.03, 0.075, and 0.00004 percent respectively followed by cypermethrin.While, chlorpyriphos and monocrotophos was found least toxic to the T.chilonis with its higher LC50 value. Thus, the monocrotophos and chlorpyriphos can be safely used in field application with T.chilonis in I.P.M.programme. While, imidacloprid should be avoided or used in alternatively with T.chilonis under strict supervision in field application.

Abstract: In a temperate broadleaf forest of Western Bhutan dominated by old growth brown oak (Quercus semicarpifolia sm) with a history of overgrazing, we aimed to study the grazing response of oak seedlings by comparing grazed and ungrazed seedlings based on some easily measurable plant functional traits such as plant height, leaf area and leaf mass area ratios (LMA). Our study found that grazing was strongly associated with shorter plant height, thicker leaves, smaller leaf area and high leaf mass per area ratios (LMA) of quercus semecarpifolia seedlings. Seedling collar diameter increment was not affected by grazing. LMA was found to be the best plant trait that could optimally predict the grazing response on plant growth. Shorter plant height, higher LMA and leaf thickness coupled with presence of more surface spines in the leaves of grazed plants could be some forms of grazing resistance or herbivory tolerance rather than adaptations to survive repeated herbivory. The study concludes that higher LMA values do not necessarily be limited to plants of nutrient poor sites or those growing under climatic stresses as generally assumed but are also attributed by anthropogenic activities like overgrazing.

Abstract: Extractives from the pine needles (Pinus roxburghii.Sarg.) are rich in resin and essential oil and are effective in protecting wood and bamboo products. This study was conducted to evaluate the efficacy of pine needle ' s extractives at different concentrations against white rot (Trametes versicolor L. Ex Fries.), brown rot (oligoporous placentas.Murr.) and some common bamboo decaying fungi-Xylaria acuminate Hill.ex Schrank. And Hypochnicium punctulatum (Cooke) J. Erikss.by malt-agar bioassay with an objective to screen its activity as preservative. Results revealed an effectiveness of pine needle ' s extractive in inhibiting the growth of the decaying fungi completely at low concentration.

Abstract: A field study was carried out to assess the effect of pruning at different height i.e.at 50, 100 and 150 cm in jatropha (Jatropha curcas Linn.) with control (no pruning) and fertility levels 50 %, 100 % and 150 percent of recommended dose of NPK in wheat on crop growth parameters and yield in agrisilviculture system. The pruning in jatropha favoured growth parameters with varying magnitudes. The growth indices like CGR, RGR, NAR, LAR, LAI, RLGR and SLW were observed to be higher under various pruning heights than under no pruning. Magnitude of reduction varied with pruning heights and fertility levels. The relative crop growth rate in terms of NAR and LAR has been higher under pruned compared to unpruned jatropha. Grain, straw and biological yield reduced by 16.56, 12.56 and 13.85 %, respectively under jatropha in comparison to sole crop which indicate that pruning is essential for improving wheat yield under jatropha based agrisilviculture system.
