Abstract: Single variable, i.e. forest density, is generally used by the foresters to evaluate forest management outcomes. Joint Forest Management (JFM), has given a role to local communities in forest management. This indicates towards the requirement of a multivariate approach to assess outcomes that includes both ecological and anthropogenic variables. In the study carried out in 24 JFMCs in 3 districts of Madhya Pradesh, having Sal (Shorea robusta), Teak (Tectona grandis), and Miscellaneous Forests, the outcomes were compared on both single variable of forest density and multiple variables (Index Value arrived at by Principal Component Analysis). On single variable 1/3rd of the 24 JFMCs were found to have better outcomes but when multivariate approach was used the number of JFMCs increased to 12 (half of 24 villages). Multivariate approach indicates more realistic assessment as social context variables are also used. Moreover, this assessment reflects the capacity of these 4 additional JFMCs to contain anthropogenic influences while being weak on the technical aspects of forest management. Thus multivariate approach gives a tool in the hands of policy makers and forest managers to make precise policy interventions - on technical or social aspects - in a particular JFMC. However, more studies would be required before it is adopted.

Keywords: Corbett Tiger Reserve, Conservation, Community, Human-wildlife Conflict
Abstract: Local community support plays a crucial role in success of conservation efforts of a protected area or key conservation species within a protected area. Corbett Tiger Reserve (CTR) is famous worldwide due to its contribution in tiger conservation primarily and so many other wild species including elephant, bear, ghariyal and mugger crocodile. To understand the community living in and around CTR, its perspective towards wildlife conservation, dependency on forest, human-wildlife conflict and developmental issues, the study was conducted in randomly selected village in north and south zone of CTR. Villagers reported dependency on forests for fuel wood and cattle grazing. Most of the villages were affected due to crop depredation and cattle lifting, whereas, occasional cases of human casualties were also reported. There were hardly any developmental activity in past. Mitigation of human-wildlife conflict, sustainable development of villages, and committed support from government agencies is required to ensure long term conservation of tiger in CTR and adjoining habitats.

Keywords: Root Trimming, Root Coiling, Shoot Topping, Pongamia Pinnata
Abstract: The aim of the present investigation was to evaluate the effect of root trimming, shoot topping, pre-sowing seed soaking treatments and seed/ pod weight on seedling quality and early growth in Pongamia pinnata. Root coiling was reduced when roots were trimmed at 5 cm length. Maximum number of nodules was observed in plants with trimmed roots as compared to untrimmed. Shoot topping at 10 cm height resulted in maximum shoot and root growth. In trial on effect of seed/pod weight on seed germination, maximum seed germination was achieved in seeds with minimum 100- seed weight among the different treatments tried. Among the pre-sowing seed treatments, maximum seed germination was observed with 8 hours of water soaking. Maximum height and diameter was observed in seeds with no water soaking treatments.

Abstract: A qualitative-floristic survey was conducted in the outskirts of Puducherry, south-eastern India, in the year 2011. A total of 431 species from 78 families were determined during the survey. Thirteen of these species, belonging to 12 genera and 11 families were of less known occurrence in this region. The regional floras indicate that nine of these species are distributed from the coast to the plains and four in hilly areas. Among the species three are not common in the Tamilnadu Carnatic region. Two of the listed species, Cynanchum tunicatum (Retz.) Alston and Crotalaria evolvuloides are reported for the first time from the Puducherry region. These plants have become endangered severely due to anthropogenic pressures. The documented species require rapid conservation efforts to mitigate their loss.

Abstract: An experiment was conducted to observe the soil enzyme activity and nitrogen assimilation by five legume species viz: Mucuna pruriens, Clitoria ternatea. Rhynchosia minima (all climbers), Crotalaria burhia and Mimosa hamata (both bushes). Higher soil organic carbon, per gram nitrate reductase and dehydrogenase activity was observed in the bush C. burhia rhizosphere as compared to control. However, maximum moisture content and NO3 -N was observed in the soil under M. hamata bush than the control. In case of NH4 -N and phosphorus, higher content was recorded in the soils under R. minima and C. ternatea climbers than the control soil. Maximum and minimum height was recorded in M. pruriens and M. hamata. Whereas, higher acid and alkaline phosphatase activity was recorded from the rhizospheric soil of R. minimaand M. hamata. Maximum collar diameter and soil electrical conductivity was observed in C. ternatea and M. pruriens soils. M. hamata proved to be well suited in alkaline soil than other species. On the basis of results obtained all these five species influenced higher enzyme activities in natural habitat as well as in the field trial and showedsignificant improvement in soil fertility as well.

Abstract: Double sampling or two-phase sampling design offers a variety of possibilities for effective use of auxiliary information such as those from high resolution remote sensing data. This study has been made to examine the possibilities of different forms of auxiliary information derived from remote sensing data in double sampling design and suggest an appropriate estimator for forest timber volume estimation in the context of preparing forest working plan inputs. A regression-cum-ratio estimator has been derived for double sampling using information on two auxiliary variables derived from high resolution satellite data. The estimator has been adopted for forest timber volume estimation utilizing tree crown diameter (x) and NDVI (z) as auxiliary variables. Relationship between timber volume (y) and 2 2 average crown diameter (x) has a higher value of R (0.733) as compared to that with NDVI (z), where R2 =0.528. It is shown that combination of these two auxiliary variables under doubling sampling design has significantly reduce the standard error of the timber volume estimate (CV of SE=11.49%) against estimates brought out by common sampling design (31% for simple random sampling, 22.34% for systematic sampling and 18.69% for stratified random sampling). This indicates that the estimator can be employed in a variety of conditions where there is good correlation of satellite derived auxiliary information with sample based ground measurements and when the cost of ground measurements is relatively high.

Abstract: Dalbergia sissoo (Shisham) is an important tree species for production of quality timber. The genetic diversity of shisham is very low: which has perhaps resulted in increased infestation by diseases and insect-pest attack. The species is eclipsed with one of the most important diseases called dieback wilt caused by Fusarium solani f. sp. dalbergiae. The biotic and abiotic factors help in the spreading of diseases in the plantation trails of shisham. In the plantation trial at Hoshiyarpur (Punjab) the dieback wilt causes the tremendous damage to standing trees of shisham. Mortality was found highest (7.65%) for the experimental trials of shisham that includes a total of 49 clones and rametes. The disease was spreading rapidly and affecting the other healthy plantation of the trials. The serious preventive management efforts and mitigation measures are required to protect the shisham trials.

Abstract: Bamboo shoots are delicious, taste sweet, rich in carbohydrate, protein, vitamin and essential amino acids. Despite these nutritious quality, bamboo shoots have cyogenic glycosides which releases hydrocyanic acid (HCN) on hydrolysis. Picrate paper method was found convenient and reliable protocol to estimate hydrocyanic and content in edible bamboo shoot. Present study was done on edible shoots of three bamboo including B.tulda and D.strictus and found that tender shoots of B.tulda are edible and good for human health as it has lower content of hydrocyanic acid. Overall middle part of the shoots contained maximum amount of HCN content in all species.

Abstract: Cones were collected during 2006 from fifty two plus trees of deodar (Cedrus deodara) selected in the state of Himachal Pradesh from the stands of site quality II/III with average age of 80-100 years and of 50-60 cm diameter class. Significant differences (p=0.05) were observed among plus trees for cone length, cone diameter, cone weight, number of seed, seed length, seed width and seed weight indicating that a significant amount of genetic variation exists among plus trees for these traits. Wide ranges in the means were exhibited for cone diameter (4.60-8.0 cm), cone weight (82-302.80 g), number of seed (120- 230) and seed weight (8.86-16.35 g). In all cases the standard error was lower than their respective means. Of the 28 correlations, cone diameter and cone weight (0.39), seed length and seed width (0.48), seed length and seed weight (0.62) and seed width and seed weight (0.58) were found to have positive and highly significant genetic correlation. Cone weight, which recorded highest estimate of heritability (98.88%), also recorded highest genetic gain of 67.56 %.

Abstract: Since its introduction in India 200 years ago, Lantana camara (Lantana) has become established and naturalised across a wide range of habitats. In Indian protected areas, lantana has been predominately managed using a range of mechanical removal approaches, costing up to 6000 per hectare. However, managed sites are rapidly recolonized by lantana and management programmes rarely achieve their goal of lantana eradication. In present study, we quantified recolonisation of lantana at sites that were either managed only once or for two consecutive years in Rajaji National Park, Uttarakhand. Rapid recolonisation and recruitment is occuring from seed dispersal from surrounding lantana populations, soil seed banks and vegetative regeneration. To manage lantana effectively we need to consider these ecological processes. An alternate management programme is recommended for long-established invasive plants such as lantana, that focuses on (a) prioritizing critical habitats that require management of invasive species (b) long-term monitoring and management scaled to timeframes of ecological processes, i.e., lantana dispersal and soil seed banks, and (c) phased enlargement of managed sites such that over time, high-priority habitats can be isolated from dispersal originating from surrounding lantana source populations.
