Abstract

The present study deals with the computation of compositional pattern diversity in Kalsa watershed, Kumaun Himalaya. Compositional pattern diversity, which is a measure of complexity of the landscape, has been measured as mosaic diversity using affinity analysis. A total of four forest types were classified using satellite remote sensing data which include temperate broadleaf forest, temperate conifer forest, pine forest and degraded forest. The results of affinity analysis showed maximum value (6.53) of mosaic diversity for temperate conifer forest followed by the temperate broadleaf forest (6.49), degraded forest (5.72) and pine forest (5.58). Pooled data from all the forest types when was taken for stratawise analysis showed maximum value (4.63) for herb layer followed by the shrub layer (3.51) and tree layer (2.50). High values (<3) of mosaic diversity indicated the presence of many underlying ecological gradients controlling the vegetation and high sensitivity of shrub and herb layer towards landscape complexity.

Abstract

75 different clones of Populus deltoides were screened in nursery stage under Eastern Indo-Gangetic conditions for recommending suitable clones for large-scale plantation in different Agro-forestry systems. Four commercial clones namely G3, G48, D121 and Udai were treated as check and these were compared with the rest of the clones. Eleven best clones (D121, D124,82-26-5, 34-N, 40-N, 25-N, UD-36, UD-5502, 90-12, UD-6502 and UD-4707) are earmarked on the basis of independent culling methods of selection. Another set of 12 clones were closely followed to the first set of 11 best clones are also graded as potential clones. The field trials of promising clones have already been undertaken for selecting the site matched clones for commercial culture of Poplar in Eastern parts of Uttar Pradesh.

Abstract

Clonal performance of the 50 promising clones of Populus deltoides, developed within and outside the country, has been statistically analysed at one third of the commercial rotation for six growth parameters viz. survival percentage, plant height, diameter, crown diameter, number of branches and volume. Genotypic and phenotypic coefficient of variation, broad sense heritability on individual plant basis, clone means basis and genetic gains have been worked out for all six growth parameters. Higher heritability was observed in diameter than plant height. Maximum heritability was well as genetic gain were obtained in volume. 30.28% expected genetic gain is achieved from selecting the 10% of 50 clones, i.e. 5 best clones namely 40-N, UDH-9116, 25-N, 63-N and UDH-1002.

Abstract

Lantana, the North American weed which migrated to India via Sri Lanka, has spreading rapidly covering vast area of forest, agriculture and wasteland etc affecting the growth of main vegetation. It can not be eradicated completely, till it is upischolar_mained. Presently the plants are either cut or dug out by traditional method. In this process, after some time the ischolar_mains of Lantana sprout again and the plants spread more densely covering still larger area. In this paper we present results of extensive field trials with a Stalk Puller developed by FRI to determine in getting rid of the menace its suitability, efficiency and economics as compared to conventional method. Detailed time and cost study was also conducted. The Stalk puller developed was found more advantageous and efficient.

Abstract

The vegetative propagation of Dendrocalamus strictus, D. membranaceus, D. hamiltonii, Bambusa tulda and B. bambos through seedlings proliferation have been studied by raising the seedlings in nursery beds with a view to reduce the nursery period to obtain massive production of tiller/rhizomes in a single phase of separation of seedlings. The results indicated that by separation of saplings through macro-proliferation after a span period of four months approximately four times of culms (tillers) and five times of rhizomes are produced in Dendrocalamus strictus, D. membranaceus, D. hamiltonii and Bambusa tulda from mother stock. The performance of Bambusa bambos is even better (5 times of culms and 6 times of rhizomes per sapling were obtained) by raising the seedlings in nursery bed by adopting better nursery practices.

Abstract

This article is an overview of the path of progress of Indian forestry over the last five decades of post-Independence era. The state ofIndia's forests and Indian forestry at the time of Independence is described. Various milestone events over this period are enumerated. The changing trends in forestry thought and practice, evolving legislation, institutions, and the evolving concepts have been detailed. India has been fortunate in having a forestry department established on scientific lines since nearly a century. The period since Independence has accelerated the process of scientific management of forests, despite the constraints faced by way of exploding population and alternate land-use practices which have impacted upon the forests in a big way. The foundations have been well laid. It now remains to the nation and to the foresters to carry the new concepts and thinking forward to preserve and protect the national forest and biodiversity wealth.

Abstract

Progress made in India about introduction and further improvement of P. deltoides is reviewed. Out of the hundreds of clones of P. deltoides introduced in India over the past four decades, only 3 to 4 clones (out of which 2 to 3 originated from the same geographical area) are widely grown by farmers in their agroforestry plantations in the plains of western Uttar Pradesh, Haryana and Punjab. In order to undertake multilocation trials ofa greater number of promising clones, 108 clones have been ranked on the basis of their field performance in two trials. Several clones rank higher than G-3 (which is presently one of the most popular clones of this species in India) and they need to be tested in field trials at multiple sites allover the poplar-growing region of the country. Germplasm of P. deltoides presently available in India comes from only about 25 per cent of the native range of this species in the U.S.A. Introduction of more germplasm from wild stands in the U.S.A is suggested. Some clones from open-pollinated progeny of G-48 and G-3 have been developed in the past few years, but open-pollinated progeny cannot be used in long-term breeding programme. Need to start control-pollination work using appropriate mating design has also been emphasised. This review has provided the basis for development of an All-India Coordinated Project for Improvement of Poplar to be executed by Forest Research Institute, Dehra Dun in collaboration with the research units of State Forest Departments and universities.

Abstract

A coordinated, multi-organisational strategy for research, development and dissemination of improved clones of P. deltoides has been developed and discussed in this paper. The programme has been initiated by research groups of various research institutes, universities and Uttar Pradesh State Forest Department under the technical guidance and coordination of the Chief Technical Advisor (CTA) and Associate CTA for Poplar. The programme envisages carrying out of multilocation clonal trials of promising clones identified to be existing in the country. A breeding programme for control pollination ofthe promising clones using 4 × 4 assortative mating design has also been launched. Seed from 104 candidate plus trees of P. deltoides from 44 wild stands in 11 States of South-eastern USA has been obtained in pursuit of this strategy. Clones will be developed at FRI from the seeds of control pollination and introduction from the U.S.A. These clones will also be tested at multiple sites under the All-India Coordinated Poplar Improvement Programme. A 10-year action for FRI and all other coordinating research units has also been prepared.

Abstract

Studies on the plant species diversity and community structure were carried in the outer fringes (l550m - 1900m) of Kedarnath Wildlife Sanctuary, Western Himalaya. Five sites were selected along the gradient of human use which represented various stages of Oak-Rhododendron Quercus leucotrichophora - Rhododendron arboreum community. The tree density varied significantly among the sites (ANOVA p<0.001) but there was no significant variation in the shrub density. The diversity of tree and shrub species have been compared separately at various sites using Shannon-Wiener index. The number of woody species was highest in the moderately disturbed site where as lowest in the Oak forest protected and artificially regenerated by the villagers. Moderately disturbed site showed best regeneration of ban Oak. However, maximum tree species diversity, structural (and possibly functional diversity) are exhibited by the old growth forest. Indicators of different seral stages have been identified and conservation implications discussed.

Abstract

The alpine and sub-alpine areas of North-West Himalayas provides a matchless wealth of highly priced medicinal, aromatic plants and are known as a natural reservoir of these herbs. In alpine pasture and meadows (bugyals) due to continuous loss of forest land, uncontrolled grazing and irregular exploitation of medicinal helrbs by commercial enterprises have resulted in depletion of valuable medicinal plants used since ancient times. There are many medicinal plants which have become rare in several tracts while a few others have fallen in the list of endangered species. Therefore it has been felt that there is an urgent need for conservation, ex-situ and in-situ cultivation of these valuable and threatened species by establishing high altitude nurseries in their natural habitat, so that regular supply to pharmaceutical industries and users could be maintained and above all this valuable flora of the alpine/sub-alpine areas of North-West Himalayas could be conserved.

Abstract

Two grasslands (Chaurs) in the core area of Corbett Tiger Reserve were studied to compare the species composition, frequency and distribution of grasses, herbs and weeds. The studyrevealcd that less frequently burnt Chaurs of first site i.e. Dhikala had high frequency of weeds and tree saplings. On the other hand. the low lying wet grasslands showed a different species composition. The frequency of grasses was significantly lower in the areas of seasonal inundation compared to elevated grasslands of Dhikala Chaur (t = 2.899. p = <0.025). Since elevated and low lying grasslands represent different ecological conditions. these would require different management practices. Weeds in low lying wet areas can be eradicated by planting native tall grasses and weeds rather than attempts of burning.

Abstract

The Shivalik landscape is extended from the Indus basin to the Brahmaputra with one gap of over 300 km from the Sapta Kosi to the Manas River. The Shivalik landscape, has been categorized under Indo-Gangetic plains and it has special significance in India's biogeography due to intermingling of taxa from the Indo-Malayan and Palaearctic regions. In the Northwest part of Shivaliks, a total of 21 wildlife protected areas had been established in six States and one Union Territory covering up to ca 2500 km². Though, more than 80% of existing protected areas of Shivaliks are in the Northwest Shivaliks, it is yet to cover some of the unique biodiversity of this region. Shivaliks in Jammu and Kashmir, Punjab, Haryana and Chandigarh are comparatively not well represented in the existing PA network of this region. Wildlife Divisions of Ropar, Hoshiarpur and Gurdaspur in Punjab, and the catchment area of Sukhna Lake in Chandigarh have been identified as potential Community/Conservation Reserves. Moreover, four clusters of Protected Areas such as 1) Kashmir, 2) Punjab and Chandigarh, 3) Himachal and Haryana, and 4) Uttarakhand have been identified in this region which may be reviewed and linked through available wildlife corridors. Of the identified four clusters of Protected Areas, two clusters require bilateral cooperation between two States for better coordination and management.

Abstract

The quality and yield of oleogum resin obtained from chir pine, varies by edaphic, climatic and genetic factors besides the tapping methods. In this context, borehole method of tapping has been found to be more feasible and superior over conventional methods in terms ofmlnimum damage to the tree, and other inputs like time, labour, etc. Physicochemical analysis, based on standard methods of rosin and turpentine separated from chirpine resin samples, was attempted for quality evaluation. The analysis of oleoresin, rosin and turpentine revealed that the borehole tapped oleoresin has less contaminants and better quality with high turpentine as compared to rill tapped oleoresin. This information may be helpful for tapping of high quality resin to the forest managers.

Abstract

Bird species are distributed along elevational gradients in mountain regions with narrow altitudinal ranges. Physical and biological environment, competitive exclusion and ecotones have been suggested as spacing mechanisms of species along elevational gradients. Interspecific aggression among closely related altitudinal replacements has been found to be one of the most important mechanisms in spacing of species in tropical mountains. In the present study interspecific aggression among closely related warbler species was tested using heterospecific song playbacks. Out of four species pairs tested interspecific aggression was detected in one pair, and it is possible that other factors related to physical and biological environment and ecotones may be more important in spacing Himalayan birds.
