Financial efficacy of a CDM forestry project for realization of carbon benefits on account of carbon sequestration service provided by the afforestation or reforestation interventions under CDM has been studied for four different sized projects. All the costs associated with the preparation of these projects such as costs on project development, validation, registration, monitoring, verification & certification, issuance of CERs, adaptation levy and the Tax implications have been taken into account and benefits were estimated assuming a carbon sequestration rate of 2tC/ha/year under two price scenarios. The results have shown that all the project sizes are financially viable with higher values of B/C ratios, in the range of 3.94 to 14.28 and the IRRs, in the range of 55% to 110%. The results also confirmed that with in a given category of the project size, the returns increase with the size of the project. The authors are of the opinion that investment in forestry A&R projects development and registration under CDM is not only a financially viable option but also the regular returns on account of CER revenue could help in sustenance for the CDM project interventions.Keywords

Comparative study on quality of Bamboo seedlings of two species, viz., Dendrocalamus strictus and Bambusa bambos raised in different sized ischolar_main trainers, polythene bags kept of mounted angle iron (MAI) beds and nursery beds has shown that significant variations exist in almost all seedling morphological parameters, viz., height, collar diameter, number of tillers, shoot biomass, fibrous ischolar_main biomass, rhizome biomass and total ischolar_main biomass among all the treatments. When compared on the basis of seedling quality parameters, viz, sturdiness, ischolar_main/shoot ratio, ratio of fibrous to total ischolar_main biomass and rhizome to total ischolar_main biomass, the seedlings raised in 300 cc ischolar_main trainers and polythene bags kept on MAI beds performed better. The study has shown that good quality Bamboo seedlings can be raised in ischolar_main trainers on large scale. The limited space available to the plant in ischolar_main trainers had no adverse effect on rhizome development. The system also facilitates mass propagation of Bamboo stock through macroproliferation.- Production of Quality Seedlings Using Improved Polythene Bag Seedling Production System

Comparative study on quality of seedlings of six important tree species, viz., Acacia catechu, Albizia lebbek, Azadirachta indica, Dalbergia sissoo, Pinus roxburghii and Prosopis julifiora raised in different sized ischolar_main trainers, polythene bags kept on mounted angle iron (MAI) beds and nursery beds has shown that significant variations exist in almost all seedling morphological parameters, viz., height, collar diameter, number of nodules, tap ischolar_main length shoot biomass, fibrous ischolar_main biomass, tap ischolar_main biomass and total ischolar_main biomass among all the treatments. When compared on the basis of seedling quality parameters, viz., sturdiness, ischolar_main/shoot ratio and ratio of fibrous to total ischolar_main biomass, it was observed that the seedlings raised in ischolar_main trainers and polythene bags kept on MAI beds performed better. The study has shown tbat seedlings of higher quality can be raised in polythene bags kept on MAI beds as compared to those on nursery beds. The seedlings raised in ischolar_main trainers were however, not only significantly smaller in dimensions of height and collar diameter when compared with seedlings raised on MAI beds but also require significantly higher capital investment. Raising of quality seedlings in 11×20 em sized polythene bags kept on MAI beds is recommended on account of better quality and long term cost effectiveness.- Seed Source Variation as Observed under Scanning Electron Microscope in Leaf Characters of Dalbergia sissoo Roxb.

Twenty seed sources of Dalbergia sisson Roxb. Scattered over a wide range of its occurrence in India were studied for the pattern of variation in micro leaf characters, viz., upper stomatal frequency, lower stomatal frequency, upper stomatal size and lower stomatal size under scanning electron microscope (SEM). The subjective observations were also recorded on other micro leaf characters such as nature and type of cuticle, stomatal openings and presence of macro/micro-hairs. The results revealed the presence of highly significant variations among the characters studied. All the quantitative characters observed under SEM showed higher values for genotypic variance and genotypic coefficient of variation as compared to the corresponding values of environmental variance and environmental caefficient of variation. There were also accompanied by high values of heritability and large amounts of genetic gain, indicating that these parameters are under strong genetic control, which can be exploited successfully for selection and further genetic improvement in this species. Lower values of stomatal frequency on lower leaf surface were recorded in the seed sources from Muzaffarnagar, Lucknow, Hyderabad and Kanpur, which has performed well in the filed. This is explained by the fact that the low stomatal frequency ofthe lower surface has led to conservation of moisture in the plants being tested under un-irrigated and semi-arid conditions. This has resulted into enhanced growth in these seed sources. The thickness of cuticle also appears to have contributed to the control of water loss from the underlying cells.- Carbon Sequestration Through Community Based Forest Management - a Case Study from Sambalpur Forest Division , Orissa

The worldwide concern over global warming led to the formation of United Nations Framework Convention on Climate Change (UNFCCC) in 1992 to deal with GHG emissions. As per the Kyoto protocol of 1997 , the industrialized countries are expected to reduce the GHG emissions by 5.5% by 2008-12 over 1990 levels. Such countries are expected to buy carbon credits from developing countries under the Clean Development Mechanism (CDM). Global negotiations are on for operationalisation of the CDM mechanism. Afforestation and reforestation have already been included under CDM , and forest conservation activities are also likely to be considered under adaptation measures. A study was carried out to estimate the creation of carbon sinks and sequestration achieved in community-protected forests of Sambalpur Forest Division , Orissa. The results have shown that 1.53 to 3.01 tonnes of carbon is being sequestered per ha per year with only protection , which can be enhanced through proper implementation of the management prescriptions. Enormous opportunities exist to sequester carbon and to mitigate climate change patterns through regeneration in India's forests.- Effect of Seed Grading on Germination Pattern of some Multi-purpose Tree Species of Jammu Region

A study was conducted in Seed Laboratory of Seed Development Division , Jammu to investigate the effect of seed grading , by size and weight , on germination of four multipurpose tree species , viz. Acacia catechu , Pinus roxburghii , Albizia lebbek and Robinia pseudoacacia. The results have shown that medium sized seed grade gave higher values of initial germination , total germination and germination values for all the species studied , except in case of Robinia pseudoacacia , where comparative values of total seed germination were recorded for small and medium sized seed grades. Grading of seeds before sowing is recommended to obtain uniform nursery stock in these species.- Genetic Variation in Biochemical Contents in Foliage of Twenty Seed Sources of Dalbergia sissoo Roxb

Twenty seed sources of Dalbergia sissoo Roxb. scattered over a wide range ofits occurrence in India were studied for the pattern of biochemical characters in foliage , viz. , total protein , proline , polyphenols , starch and total carbohydrate. The results revealed the presence of highly significant variations among the characters studied except starch content. Genotypic coefficients of variance and variability were large compared to the environmental coefficients of variance and variability for total protein , proline , polyphenols and total carbohydrate , indicating that these are under genetic control. Starch content was observed to be under the influence of environment. The estimates of heritability and expected genetic gain were high for all characters , except starch content , which registered lower values of heritability and genetic gain. The correlations of starch content with survival and growth at phenotypic level were positive and significant. The seed sources from Lucknow and Muzaffarnagar exhibited good performance and are recommended for immediate planting programmes in this region.- Standardization of Pricking Stage of Chir Pine and Khair Germinants in Root Trainers

A trial was carried out to standardize the best stage for transplanting the germinants of Pinus roxburgii (Chir pine) and Acacia catechu (Khair) in the ischolar_main trainers to obtain maximum survival. Transplanting of germinants of Chir pine in 11-13 days and of Khair in 10-12 days after sowing, gave maximum survival percent. Poor survival of transplanted germinants was recorded in case of direct sowing in both the species and transplantation at first leaf (needle) stage in case of Chir pine.- Variation in Rooting Response of Different Clones of Casuarina equisetifolia

The ischolar_maining response of 20 different clones of Casuarina equisetifolia under different concentrations of Indole Butyric Acid (IBA) was studied in a factorial RBD experiment. Significant variations in ischolar_maining per cent and number of ischolar_mains were recorded among the different clones, treatments and their interactions. The variations observed in ischolar_main length were significant among the clones only and non-significant among treatments and clone-treatment interaction. The treatment IBA 4000 ppm performcd the best for all the parameters studied. The treatment increased ischolar_maining by 88.38% and number of ischolar_mains per cladode by 73.33% over control. The findings indicate the importance of including ischolar_maining ability of a clone (genotype) as an important criterion for its selection and evaluation.- Estimation of Variability in Growth Characters of Forty Clones of Tectona gralvdis L.F.

Three and a half-year-old plants of 40 clones of Tectona grandis were quantitatively measured for plant height, collar diameter and survival per cent to assess the variability. Significant variations were recorded in all the three parameters studied. The extent of variations in growth parameters of height and collar diameter was large compared to survival per cent. Plant height and collar diameter gave comparable values for genotypic and phenotypic variations and coefficient of variation indicating that these parameters are under genetic control. Maximum heritability was observed for height (85.50%) followed by collar diameter (74.02%) compared to 23.07% in survival per cent. Both the growth attributes, i.e., height and collar diameter were found to be heritable and there is a scope for considerable genetic gain through selection. Plant height and collar diameter also recorded the higher genetic gains 46.63% and 36.83% respectively, indicating effectiveness of these parameters for selection of best individuals/ clones.- Intra-population Variation in Albizia procera : POD, Seed and Germination Characteristics

In order to estimate intra-population variability, some mother trees of Albizia procera of Jabalpur (Madhya Pradesh) region were evaluated for their pod, seed and germination characteristics. Significant variation within the population was recorded with respect to almost all morphological characters of pod, seed and germination. Large amount of variation was observed in mother trees dbh, seed weight per pod, percentage of deformed seed, germination per cent, percentage of hard and dead seed and field emergence. No significant relationship between mother tree dbh and any of the parameter studied was observed except for percentage of hard seed. Selection of superior trees based on germination testing in addition to tree characters like dbh has been emphasised for quality seed collection.- A Report on Unusual Seedlings of Sesbania sesban (L.)

Rooting trial was carried out using ischolar_main cuttings of seven multipurpose tree species in low cost mist chamber designed and developed in Tropical Forest Research Institute, Jabalpur. Maximum ischolar_maining (84.44%) was obtained in ischolar_main cuttings of Dalbergia sissoo whereas Tectona grandis gave a very poor ischolar_maining response (10.00%). Albizia lebbek and Albizia procera, which are otherwise difficult to ischolar_main species through branch cuttings, gave 56.67% and 66.67% ischolar_maining through ischolar_main cuttings respectively. The findings of the present study highlight the importance of vegetative propagation through ischolar_main cuttings and its substantial scope in tree improvement programmes. The technique enables successful vegetative propagation through ischolar_main cuttings of multipurpose tree species including some of the difficult to ischolar_main species without the assistance of growth hormones.- Improved Seedling Quality of Polybag Plants of Albizia procera - Use of Mounted Angle Iron Beds

A trial was carried out to study the effect of polybag size and number of perforations at the bottom on different seedling growth and quality parameters in case of Albizia procera seedlings raised on Mounted Angle Iron beds. Highly significant differences in seedling growth parameters viz., height, collar diameter, length oftap ischolar_main, ischolar_main and shoot biomass, and seedling quality parameters viz. sturdiness, ischolar_main/shoot ratio, number of nodules and ratio of secondary + tertiary ischolar_main biomass to total ropot biomass, were observed among different treatments. The treatment T3 (Polybag size 23 x 11 cm with 4 perforations at bottom) performed the best in respect of seedling growth parameters with height 81.33 cm, collar diameter 0.76 cm, length of tap ischolar_main 16.90 cm, shoot biomass 14.36 gm and ischolar_main biomass 11.67 gm. However the treatment T12(Polybag size U x 6 cm with 6 perforations at bottom) recorded best values for most of the seedling quality parameters viz. sturdiness 82.03, ischolar_main/shoot ratio 1.21 and ratio of secondary + tertiary ischolar_main biomass to the total ischolar_main biomass 0.44.- Preliminary Observations on Genetic Variability and Character Association in Dalbergia sissoo Roxb

Twenty provenances/seed sources of Dalbergia sissoo Roxb. scattered over a wide range of its natural occurrence in India were studied for the pattern of genetic variation and character association after two and a half years of field planting in a statistically laid out trial. The results revealed the presence of highly significant variations among the provenances for height, number of branches and survival per cent. There are fair differences between phenotypic and genotypic coefficients of variability indicating that these parameters are sensitive to environmental changes. The estimates of heritability and expected genetic gain were low to moderate for all the characters, except number of branches which registered comparatively higher values of heritability (61.95%) and genetic gain (28.45%). The correlations among most ofthe characters at phenotypic level were positive and significant indicating that simultaneous improvement of these characters can be brought about easily. The provenances from Lucknow and Muzaffernagar exhibited good growth performance and are recommended for immediate planting programmes in this region until the final results are obtained.- Carbon Sequestration Potential under Agroforestry in Rupnagar District of Punjab

The paper reports study on carbon sequestration potential and cost effectiveness of tree growing operations on farm lands of Rupnagar District of Punjab. Project based-comprehensive mitigation analysis process (PRO-COMAP) was used to estimate the sequestration potential between 2005 and 2030. The results show that there is a potential to sequester 821,961 tons of carbon during the period of analyses on farm lands of Rupnagar. The whole of this potential could be achieved at a negative cost where non-carbon revenue is sufficient to offset the direct costs. Agroforestry options seems to be attractive for the district as large number of farmers and land area is dedicated to agriculture, supported by availability of irrigation facilities and high productivity of land. The development of agroforestry, however, faces certain barriers due to unorganized markets, poor technical and financial support and lack of extension activities by the Government, which must be addressed before the mitigation activity is undertaken.- Genetic Variability and Character Association in Acacia catechu Willd

Twenty genotypes of Acacia catechu Willd. scattered over Jammu region in their natural range were studied for the pattern of genetic variation. Higher values of genotypic varianceand genotypic coefficient of variation as compared to environmental variance and environmental coefficient of variation in germination and growth characters, indicating that they are under genetic control. The heritability and expected genetic gain were also observed to be high for these characters, except germination per cent. The correlations between germination per cent, seedling height, collar diameter and biomass at phenotypic level were positive and significant. The families F4, F5, F12, F13, F14 and F15 exhibited good performance and are recommended for further genetic improvement program in this species. The positive relationship between dbh of the CPT and the important parameters of the progeny, i.e, seed weight, germination per cent and seedling height can be utilized for meeting the interim seed requirement of the species as the seed collected from the trees with higher dbh is expectedto perform better at nursery stage- Improved Seedling Quality of Polybag Plants - Use of Mounted Angle Iron Beds

Polybag raised seedlings have many disadvantages viz., ischolar_main coiling and distortion, scanty lateral ischolar_main development and frequent shifting operations. To deal with the problem, Mounted Angle Iron (MAI) beds have been designed. Polybags with perforations at the bottom are placed on these beds. The tap ischolar_main is expected to get exposed through the perforations and air-pruned leading to development of fibrous ischolar_main system. A trial was carried out to compare the performance of polybag seedlings of Albizia procera S1, Acacia nilotica S2, Sesbania grandiflora S3. And Sesbania sesban S4., raised on MAI beds with those raised on nursery beds. The observations suggest that the seedlings raised on MAI beds recorded higher fibrous ischolar_main biomass i.e.I.08g, 0.79g, O.94g and 0.82g per plant as compared to 0.49g, 0.30g, 0.36g and 0.30g of control (nursery bed seedlings) for S1, S2, S3. and S4. respectively; and number of nodules i.e. 75.3, 20.6, 55.2 and 52.9 as compared to 24.5, 9.3, 25.4 and 11.5 in control for S1, S2, S3. And S4 respectively. In case of ischolar_main length, leaf biomass and primary ischolar_main biomass, the nursery bed raised seedlings recorded higher values for all the four species. No difference was observed in case of seedling height, collar diameter, stem, biomass and total biomass. The improved polybagseedlings production system has enhanced the quality parameters of seedlings i.e. fibrosity and nodulation.- Variation in Rooting Response in ten Provenances of Azadirachta indica A.

The ischolar_maining response of ten indigenous provenances of Azadirachta indica under the effect of different treatments viz., IAA, IBA and Thiamine was studied in a factorial RBD experiment. Signifiant variations in almost all parameters were recorded among the different provenances, treatments and their interactions. The treatment IBA 1000 ppm performed the best for all the parameters studied. The treatment increased ischolar_maining by 85.5%, number of ischolar_mains per cuttings by 240.8%, maximum ischolar_main length by 68% and ischolar_main dry wt. by 218.7% over control. The provenance Mandore, Rajasthan (P9) showed overall best ischolar_maining response with 64.17% ischolar_maining, 9.64 number of ischolar_mains per cutting, 6.15 em maximum ischolar_main length and 0.075% gmIcutting ischolar_main dry wt. The interaction of provenance Midnapur, West Bengal (P5) with treatment IBA 1000 ppm (T3) gave best results in respect of number of ischolar_mains per cutting (17.67), maximum ischolar_main length (7.61 cm) and ischolar_main dry weight (0.163 gm/cutting). However, the provenance Dodaballapur, Karnataka (P10) with treatment IBA 1000 ppm (T3) gave the maximum ischolar_maining (96.67%). The findings indicate that it is desirable to include ischolar_maining ability of a provenance as an important criterion for its selection and evaluation.- Path Analysis in Dalbergia sissoo Roxb.

In the integrated structure of the plant, the overall correlation observed between two variables is a function of a series of direct and indirect relationships between different variables. To understand the specific forces in building up the total correlation towards productivity in case of Dalbergia sissoo, Path coefficients analysis was carried out. Fourteen characters were included to find out their direct and indirect effects on field height (i.e. productivity). The analysis revealed that the characters polyphenol, number of branches, pod length and germination per cent had higher direct or indirect effects on field height and could be collectively used as selection criteria for improving productivity in Dalbergia sissoo.- Seed Source Variation in Germination and Early Growth Among Ten Indigenous Populations of dalbergia sissoo Roxb.

Ten provenances/seed sources of Dalbergia sissoo Roxb. Scattered over a vide range of its natural occurrence were studied for germination, nursery and early field performance. Significant variations among the provenances were observed in parameters, viz., germination per cent, seedling height and collar diameter, and field height and survival per cent. Variations for most of the traits studied were non-clinal type, except seed germination per cent, which showed significant negative correlation with altitude. Low germination among the seeds of higher elevation populations was found to be due to higher dormancy existing in these seedlots. The inverse relationship observed between seed germination percent and field height and collar diameter seems to be the result of poor germination due to dormancy existing in higher elevation seed sources. Such relationship may not be observed if the seeds are properly treated before sowing. The provenance T9 (Oachghat, Solan), Tl (Kukrail, Lucknow) and T4 (Orai, U.P.) were found to be more vigorous on the basis of field performance and can be used for meeting the immediate seed requirement for afforestation programmes.- Tetrazolium Test for the Seeds of Acacia nilotica Willd.

Seed germination pattern of 30 provenances belonging to 5 subspecies of A. nilotica namely tomentosa, indica var. jaquemontii, indica var. cuppressiformis, nilotica, and indica from 5 countries namely India, Sudan, Pakistan, Yemen and Senegal were studied in nursery conditions. Provenances of A. nilotica from Pakistan showed a very good performance and depicted a parabolic (asymptotic) type of germination curve. However subsp. indica var. cuppressiformis from Pune (Maharashtra, India) gave maximum percentage of seed germination (75%). Significantly a good correlation was evident between cumulative seed germination&number of days elapsed. Relative delay in the initiation of seed germination was found maximum in provenances of subsp. tomentosa and subsp. nilotica.- Carbon Sequestration Potential of Selected Plantation Interventions in Terai Region of Uttarakhand

Selected afforestation and reforestation interventions have been studied in the Terai region of Uttarakhand with the objectives to assess their carbon sequestration potential, and cost-effectiveness exclusive and inclusive of carbon benefits. The excel spreadsheet model "Project Based Comprehensive Mitigation Assessment Process" was employed to workout the annual incremental carbon sequestration, cost effectiveness indicators and likely benefits under different carbon price scenarios for each selected afforestation and reforestation intervention. The results have shown a wide range of sequestration potential, which varied from 0.74 tC/ha/yr in case of amla block plantation to 2.34 tC/ha/yr for Triphala block plantation, calculated for the assessment period 2008-38. However, for the 'with wood products' scenario, the maximum sequestration potential was observed for poplar block plantation (2.41 tC/ha/yr), closely followed by Eucalyptus block (1.73 tC/ha/yr), while teak block plantation showed sequestration potential of 1.50 tC/ha/yr. Among the selected plantation interventions under 'without wood products' scenario, Triphala block, NTFP block, and NTFP bund were observed to be associated with maximum carbon benefits, viz., Rs. 1976/-, Rs. 1841/- and Rs. 1518/- per ha per year respectively. The study has demonstrated that plantation interventions involving NTFP species associated with appreciable recurring non-carbon benefits are more likely to succeed as afforestation and reforestation CDM project interventions compared to fast growing commercial tree species, viz., popular and Euealyptus on furmlands.Keywords

Around 55 provenances / seed sources of Dalbergia sissoo Roxb. were collected from vast expanses of India and Nepal as part of National Provenance Trial by ICFRE in 1994 - 1995, and 40 seed sources were planted in Basantar Bela, Samba district of Jammu region of J&K in July 1995 in a randomized complete block design. The seed sources have been evaluated during January 2010 for survival and growth parameters. It was observed that the parameters of diameter, height and volume over bark varied significantly with regard to seed sources, but not with regard to replications. The wide variations observed in the trial cannot be explained unambiguously from climatic differences between the locations of these seed sources alone, as evidenced by correlation studies. It was further established that seeds from Mirzapur, Nepal and Pratapgarh manifested distinct advantages concerning the survival, height, diameter and volumes of the stems, thus demonstrating their utility in bolstering mass plantation in the north western Indian region and elsewhere. Further studies appear obligatory to apprehend this indication.Keywords
