Keywords: Terminalia Chebula, Chebulic Myrobalan, Thrips, Dixothrips Onerosus, Shiwaliks, Gall.
Abstract: Studies on gall induction and life history of the (Dixothrips onerosus) were carried out in Kalka, Pinjore and Morni areas ofHaryana Shiwaliks and Jaman Ki Sher (District Sirmaur), Bhota (District Hamirpur) and Bilaspur district of Himachal Pradesh. Three generations were noticed inside the gall under North West Indian Shiwalik conditions. By the first week of November, the galls dried up and small cracks appeared at the base of the gall. The adults left the galls through these cracks to pass winter among the fallen leaves, though some of them passed winter in late formed galls as well. The adults resumed their activity in February when the tender leaves started appearing on the plant The gall induction by this pest on hararin Shiwaliks assumes greater significance in view of the importance of its fruit in modern allopathic and Indian system of medicines, insect and host plant interactions, harm done by the insect to the host plant on one hand and possible use of galls in medicinal health, functional food, and nutraceuticals applications. The life history of Dixothrips onerous has also been worked out for the first time in the area.

Subject: Restoring Lantana camara Invaded Tropical Deciduous Forest: The Response of Native Plant Regeneration to two Common Lantana Removal Practices
Keywords: Community Composition, Restoration, India, Invasive Species, Regeneration.
Abstract: Lantana camara (hereafter, Lantana), a pantropical invasive species, has become widespread across India. Lantana forms dense thickets in the understory of deciduous forests, adversely affecting regeneration of native vegetation and habitat for wildlife. Lantana removal is now an integral part of protected area management in India. We tested the relative efficacy of two Lantana removal techniques—cutting and burning, and uprooting—commonly employed by forest managers. Our objectives were a) to see which technique resulted in better native plant recovery post- Lantana removal; and b) to evaluate the mechanisms underpinning Lantana's success in these forests. The two techniques did not differ greatly in post-removal recovery of native vegetation. However, there was a marked difference in the post-removal recovery of Lantana. Lantana in the uprooted plots was significantly denser than in the cut-and-burnt plots, making the latter the more effective of the removal techniques. Given the numerical dominance of Lantana seeds in the soil, and their wide dispersal, no Lantana removal is likely to be effective without post-removal monitoring and weeding. We also recommend post-removal planting of species that can pre-empt Lantana re-colonization, and respond positively to disturbances like fire and grazing, that are known to promote Lantana's spread.

Abstract: In this study, fuel properties (basic density, calorific value, ash content, volatile matter content and fixed carbon content) of important fuel wood species i.e., Casuarina equisetifolia has been investigated. Study on chemical, elemental and gasification characteristics of Casuarina equisetifolia has also been carried out Ash content, volatile matter content and fixed carbon content was found to be 0.6 %, 83.6% and 15.8%, respectively. Higher calorific value (20.29 MJ/kg) was observed in Casuarina equisetifolia wood biomass. Based on experimental results, Casuarina equisetifolia wood was found to be a suitable feedstock for energy conversion through gasification. The emphasis was given to Casuarina equisetifolia because of the fast-growing nature of the plant and produce more biomass in short time. Casuarina equisetifolia is one of the important fuel wood trees, which is widely available in coastal zones of India and is accepted to play major role in future bioenergy schemes.

Keywords: Acacia mangium, Carbon Sequestration, Biomass Production.
Abstract: The study on biomass production and carbon sequestration of Acacia mangium Willd. under varying plant spacing was conducted at College of Forestry, Orissa University of Agriculture and Technology (O.U.A.T), Bhubaneswar, India during 2013 – 2014 on 10 year old experimental plantation. The study explored a 10 year old A. mangium plantation embodying ten different spacing with the objective to find out the optimum spacing of A. mangium which is a fast growing NFT and popular now a days in agroforestry and farm forestry programmes. The biomass ranged from 106.84 to 131.46 t/ha, 19.84 to 34.27 t/ha, 22.58 to 30.28 t/ha and 42.96 to 48.97 t/ha in stem, branch, leaf and root, respectively. The total biomass varied from 192.2 to 244.91 t/ha. The overall biomass production was found to be maximum under S1(2m×1m) which was at par with S2, S3, S4, S5 and S6. The minimum values were observed under S10 with a parity of values with S9 and S6. The total biomass decreased with increase in spacing. The carbon sequestration ranged from 50.75 to 62.44, 9.42 to 16.27, 10.73 to 14.38 and 20.41 to 23.23 t/ha in stem, branch, leaf and root, respectively. The total carbon sequestration varied from 91.30 to 116.33 t/ha which decreased with increase in plant spacing. S showed highest value which 1 was at par with 2, S3, S4, S5 and S6 The S6 was found as optimum spacing. because among S to S spacing, cost of production was lowest in S due 1 6 6 to less number of pit preparation, less number of planting materials and also less cost of harvesting. Further, this spacing can provide scope for intercropping as A. mangium is a suitable tree species for agroforestry. Hence, S6 i.e 4m×2m was found to be the most suitable spacing among the ten different spacing tried.

Abstract: The present investigation was carried out under the willow plantations established by Plantation Division of State Forest Department in Anantnag, Bandipora, Baramulla and Ganderbal Districts of Kashmir valley. Two plantation blocks of willow were selected in each District The existing Soil organic carbon, bulk density and soil carbon sequestration under Salix trees at all the selected locations were determined. The mean values for bulk density obtained from the different sites exhibit a significant variation while was found non-significant during the period of investigation. Soils under the plantations at Bandipora exhibited lowest bulk density of 1.299 g cm3, while the soils at Anantnag had the maximum values of 1.360 g cm*. The maximum soil carbon density of 68.07 t ha'1 was recorded at Bandipora, followed by 67.931 ha'1 at Baramulla, 66.861 ha'1 at Ganderbal and 66.431 ha'1 at Anantnag. The results indicate that there was a significant (p<0.05) periodic (CAI) stratification in soil carbon density values recorded during the period of investigation. Maximum (4.6611 ha1] annual addition in SOC was recorded under the canopy of willow trees at Bandipora, the least yearly accretion (4.416 t ha1) was exhibited by soils developing under the canopy of this species at Anantnag. The data further envisages that SOC recorded in soil samples collected from adjacent fallow lands were far less (34-50%) as compared to those obtained under the canopy of willow plantations at all the locations.

Abstract: Measurement of growth of an individual tree forms the basis of measurement of growth/increment of forest and ultimately, management of forest. For trees showing annual rings, growth relationship i.e. growth of breast height diameter, height and volume with age require analysis of the whole stem of the tree known as 'Stem Analysis'. Growth of breast height diameter with age can be found by 'Stump Analysis' also. During this analysis, data are collected from of trees/stumps in the field and then collected data is analysed. A computer/mobile based program in which the field data can directly be entered and all computation including graph plotting will be done by computer/mobile, is always desirable for those field foresters who are involved in Mensuration exercise. Considering the utility of such application in mind, a computer software program in MS Excel and a mobile based application have been developed for Stem and Stump Analysis. Both the applications have been checked with data collected for Cedrus deodara at Kanasar, Chakrata Forest Division, Dehradun and the results obtained are highly satisfactory. This paper discusses the method used in developing these applications and efficacy and utility of both the applications in preparation of working plan and volume tables.

Keywords: Forest Cover, Growing Stock, Assessment, Recorded Forest Area, Green Cover, Productivity/Quality.
Abstract: Quality/productivity of green cover may be appraised in various ways and in different contexts. The present study attempted to evaluate productivity in terms of GS analysing data published in ISF Reports. It worked out trends in productivity in terms of quantity of GS per unit area within RFA, status of GS outside RFA and quality of green cover (FC+ tree cover) at National and State level by analysing the assessments of GS made by FSI so far. While highlighting constraints in the convergence of forest cover with GS in forests and tree cover with GS in TOF, the study brought to light a reduction of 583.02 million cum GS @ 7.19 cum per hectare in India's recorded forests from 1993 to 2015. The comparison of first biennial (2003) assessments of GS with the latest one (2015) figured out decrease in GS within RFA by 586.36 million cum @ 48.86 million cum per year. The analysis also unfolded that the initial GS assessments (1993, 2003 and 2005) owing to small no. of sample plot were not comparable to the later assessments (2009 to 2015). Therefore, analysis of later assessments (2009 to 2015) brought out reduction of 329.813 m cum (303.61 million cum within RFA and 26.2 million cum in TOF) in GS of the country (both in forest and outside forest) in spite of 10577.08 km2 increase in the total green cover construing thereby enhancement in the extent of green cover but downturn in quality. The annual rate of decrease in GS worked out as 54.969 million cum (50.6 million cum within and 4.37 million cum outside RFA) from 2009 to 2015.Likewise the productivity in terms of GS per unit area of green cover (in forest + in TOF) declined from 77.816 cum/ha. in 2009 to 72.627cum/ha in 2015 though the decline was sharp @ 5.546 cum/ha. in 2013 which mildly recovered thereafter.

Abstract: Bioethanol and hemicelluloses are the most abundant renewable biomacromolecules found in the biosphere. Bioethanol has received special attention worldwide due to gradual depletion and increasing price of fossil fuels. Bioethanol from cellulosic biomass has gained popularity because of convenience in processing and economic nature. In the present study, chemo-enzymatic saccharification of jack fruit peel waste employed which yielded p to 30.58 g/l of reducing sugar. Fermentation was carried for bioethanol production by using filtrates of treated jackfruits peel extract with Saccharomyces cerevisae. Bioethanol yield was monitored throughout a fermentation period of 5 days; bioethanol yield was found to be a maximum of 3 g/l from Jack fruit peel waste hydrolysate after distillation. The use of jackfruits peel for the production of bioethanol shall provide with a novel perspective to recycle organic waste for renewable energy.

Abstract: Hybrid composites of teak wood flour/cotton stalk flour and polypropylene were fabricated at a fixed plastic to fiber ratio of 80:20 and variable proportions of the two fibres by extrusion method. Maleic anhydride grafted polypropylene (MAPP) was used as the coupling agent. The tensile specimens of neat PP and hybrid composites were subjected to 25 kGy dose of gamma radiation. The tensile strength was estimated using Universal Testing Machine (UTM). Thermal analysis of the samples has been carried out at a heating rate of 10ºC min-1, from 50ºC temperature to 500ºC, in a n inert atmosphere. The outcome of gamma irrardiation on thermal and tensile properties was analysed. A notable improvement in tensile strength and tensile modulus has been observed, with modest decline in thermal stability. The improvement in tensile strength of hybrid composite as compared to neat PP, can be attributed to the cross-linking effects of both the compatibiliser and the gamma irradiation.

Abstract: Seabuckthorn (Hippophae spp) is a perennial, thorny bush with yellow berries in the cold desert region of Leh in Ladakh. Seabuckthorn is popularly known as ‘Wonder Plant’, ‘Ladakh Gold’, ‘Golden Bush’ or ‘Gold Mine’ of cold deserts. It is rich in pharmaceutical, therapeutic, and cosmetic values and serves as a source of multivitamins and food supplement. Besides, it also contributes to fix nitrogen in the soil making it more fertile. The shrub can withstand extreme temperature from -43ºC to +40 ºC and is considered drought resistant. These two characteristics make the shrub an ideal plant species to establish in cold deserts. It is naturally distributed over 11, 500 hectares in Ladakh region. Seabuckthorn commonly grows on forest department land, wastelands, along the riverbed and the monastery land. Monasteries use it extensively as fuel since it makes excellence coal. It is estimated that seabuckthorn plantation fix 180 kg nitrogen per hectare every year. This study essentially looks at the opinions of various stakeholders in the region. What has emerged from this study is that the seabuckthorn trade needs to develop into an industry. This basically means that the current production has to significantly scale up, more value addition done, newer and more secure markets to be explored and more employment opportunities created for the local people. The different components pertaining to setting up of an enterprise like the form of organization, fundraising, operations and management and legal aspects need to be further explored. Economic integrity of Seabuckthorn plant in Leh and its adjoining areas upgrade the integrity of Seabuckthorn plant in Leh and its adjoining areas upgrade the economic stability to the local inhabitants. The data on economic probability of cultivating seabuckthorn orchards amounts to Rs 255387.60 ha-1 discounted at an interest rate of 12 % during the rotation period of 6 years. The gross and net income realized from this plantation after six-year rotation cycle is Rs 479577.02. The present analysis also reveals that the farmer can realize NPV of Rs 224189.41 ha-1 with equivalent annual annuity of Rs 54528.63 and can get Rs 1.88 for every rupee invested at an interest rate of 12%.The products made from seabuckthorn berries in Ladakh have both local and national demand due to nutritive value. The result of the survey conducted in the local market reveals that Seabuckthorn products in Ladakh and adjoining areas are sold with 50 to 300 per cent after value addition. In addition, six-year-old seabuckthorn plantation on one hectare can produce 18 tons of firewood which is equal to nearly 12.6 tons of standard coal.

Keywords: Ashwagandha, Herbal, Disease tonics, Starchy roots, Withanolides, Glycowithanolides, Alkaloids, etc.
Abstract: “Ashwagandha” products are one of the major herbal components of various disease tonics mentioned in Indian systems of Medicine. It is an erect branching under shrub reaching about 150 cm in height, usually clothed with minutely stellate tomentum; leaves ovate up to 10 cm long, densely hairy beneath and sparsely above, flowers are greenish or yellow in axillary fascicies, bisexual, pedicel long, fruits globose berries which are orange coloured when mature, enclosed in a persistent calyx. The freshy starchy roots of Ashwagandha when dry, they are gradually tapering down with a brownish white surface, cylindrical and pure white inside when broken. Majority of the constituents are withanolides (steroidal lactones with ergostane skeleton), glycowithanolides and alkaloids. These include withaferin A, withanolides G & D, sitoindosides and withasomnine. It helps to induce the body by rejuvenating the reproductive organs, just as a tree is investigated by feeding the roots.

Abstract: Despite numerous exploration and in-depth studies in the Western Himalaya on various themes, many areas remain under-explored. One such under explore area is Sundardhunga Valley, Bageshwar (Uttarakhand) in Western Himalaya. A detailed floristic survey was conducted during 2017-18.A total of 520 species of angiosperms ( 286 genera and 92 families) , 45 species of Pteridophytes (24 genera and 15 families) and 7 species of Gymnosperms ( 5 genera and 4 families) were recorded within about 75 km2 vegetated area above 2000 m elevations. The dominant families were Asteraceae (47), Rosaceae 37) ,Poaceae ), Ranunculaceae (20) and Polygonaceae (19) among angiosperms and Polypodiaceae (12) and Apleniaceae (5) among the ferns. Owing to difficult terrain and low accessibility to people and livestock during the growing season (June-September) the valley has luxuriant diversity.
