Multiple Usages of Forest Trees by the Tribes of Kalahandi District, Orissa, India
Vol. 5(6), pp. 333-341, June 2013 DOI: 10.5897/IJBC11.129 International Journal of Biodiversity ISSN 2141-243X © 2013 Academic Journals http://www.academicjournals.org/IJBC and Conservation Full Length Research Paper Multiple usages of forest trees by the tribes of Kalahandi District, Orissa, India Saujanendra Swain1* and Gopal Chandra Mohapatra2 1M. S. Swaminathan Research Foundation, Phulbad, Jeypore RS-764 002, Koraput, Orissa, India. 2Field Expert, Orissa Forestry Sector Development Project, Bhubaneswar, Orissa, India. Accepted 31 May, 2013 Forest trees are the integral part of human society. Forest trees provide both direct and indirect benefits to humans. The number of products provided by trees worldwide is extensive. The wood, bark, leaves, fruits, seeds and roots of trees yield food, fodder, shelter, medicine, fibre, resin, oils and other numerous products used for subsistence of people living in rural and tribal areas. There is a great international interest in the so-called multipurpose trees, but in practice, virtually all tree species can be used for more than one purpose. In some areas in India, the life and livelihood of the tribes depend on trees, as they provide all the commodities required by them in their day to day life. However, in recent days, there is rapid depletion of forest covers, which results in loss of these valuable trees, thereby affecting the livelihood and culture of the tribes. In this regard, the paper is an attempt to study, based on sustainable development strategy of forest resources, the ethnobotany on multiple uses of tree species by the tribes of Kalahandi District, Orissa, India. -

i Maejo Int. J. Sci. Technol. 2009, 3(01), i Maejo International Journal of Science and Technology ISSN 1905-7873 Available online at www.mijst.mju.ac.th Editor's Note The year B.E. 2552 (A.D. 2009) has brought about a number of changes in connection with this journal. First, it is now entering its 3rd year of activity since its conception with its first volume and first issue being launched 2 years ago. Second, it is now a 100% e-journal (no more hard copies), which means an article can be published anytime as soon as it is ready (as always being the case from the beginning, however.) Thirdly, our managing editor, Dr. Weerachai Phutdhawong, the technical and key founder of this journal, has reluctantly left us for a new academic position at Kasetsart University. Without him from the start, this journal would never have been as it is now. He and the webmasters of Maejo University have jointly created a website for a journal which is freely, fully, and easily accessible. And this is most probably one of the factors that contribute to its unexpected and continuing popularity from the beginning as well as to the increasing international recognition of the journal now.* Lastly, the editor sincerely hopes that, with a well-laid foundation in store and a strong editorial committee at present, and despite his failing health after two years in office, which may result in a new editor for the journal in the near future, this journal will continue on well towards serving submitters, both local and abroad, as well as improving on its standard further. -

WOOD RESEARCH doi.org/10.37763/wr.1336-4561/65.6.963974 65 (6): 2020 963-974 EFFECT OF HEAT TREATMENT AND WAX IMPREGNATION ON DIMENSIONAL STABILITY OF PTEROCARPUS MACROCARPUS WOOD Lin Yang1,2, Tianqi Han1, Yudong Fu1 1Nanjing Forestry University China 2Northeast Forestry University China (Received March 2020) ABSTRACT In order to improve dimensional stability and control deformation, heat treatment (HT) and wax impregnation (WI) were conducted to large size boards (LB) of Pterocarpus macrocarpus and the tangential swelling were compared in various relative humidity (RH) conditions. The results show that the tangential swelling and shrinking of control group and treated group performed differently corresponded to various relative humidity (RH). Comparing with control group, the swelling ratio of HT combined WI group was much less, and followed by 180°C-3h HT group. The maximum swelling ratio decreased by 31% and 29% in humidity chamber and indoor conditions respectively. The swelling ratio was affected by size of samples, LB showed smaller welling ratio than small sample. Wax filled in cell cavities and presented uneven distributions after impregnation. The rate of wood hygroscopicity was reduced after HT combined WI treatment which was an effective method on improvement of wood dimensional stability. KEYWORDS: Pterocarpus macrocarpus, heat treatment, wax impregnation, dimensional stability, modification. INTRODUCTION Pterocarpus macrocarpus mainly grows in Myanmar, Laos and Thailand, belonging to the butterfly-shaped flower Pterocarpus, Rosewood mahogany (Azratul et al. 2017), which is categorized as a red Suanzhimu class in China national standard— “Hongmu” (GB/T18107- 2017). Pterocarpus macrocarpus has straight trunk, branches few and it is excellent wood tree species. -

Germination and salinity tolerance of seeds of sixteen Fabaceae species in Thailand for reclamation of salt-affected lands. Biodiversitas 21: 2188-2200. Over the years, areas affected by salinity have increased dramatically in Thailand, resulting in an urgent need for reclamation of salt-affected areas using salinity tolerant plant species. In this context, seed germination is an important process in plant reproduction and dispersion. This research aimed to study the ability of 16 fabaceous species to germinate and tolerate salt concentrations of at 6 different levels (concentration of sodium chloride solution, i.e., 0, 8, 16, 24, 32, and 40 dS m-1). The germination test was conducted daily for 30 days, and parameters such as germination percentage, germination speed, and germination synchrony were calculated. The electrical conductivity (EC50) was used to compare the salt-tolerant ability among the 16 species. -

Maintenance and conservation of Dipterocarp diversity in tropical forests _______________________________________________ Mohammad Nazrin B Abdul Malik A thesis submitted in partial fulfilment of the degree of Doctor of Philosophy Faculty of Science Department of Animal and Plant Sciences November 2019 1 i Thesis abstract Many theories and hypotheses have been developed to explain the maintenance of diversity in plant communities, particularly in hyperdiverse tropical forests. Maintenance of the composition and diversity of tropical forests is vital, especially species of high commercial value. I focus on the high value dipterocarp timber species of Malaysia and Borneo as these have been extensive logged owing to increased demands from global timber trade. In this thesis, I explore the drivers of diversity of this group, as well as the determinants of global abundance, conservation and timber value. The most widely supported hypothesis for explaining tropical diversity is the Janzen Connell hypothesis. I experimentally tested the key elements of this, namely density and distance dependence, in two dipterocarp species. The results showed that different species exhibited different density and distance dependence effects. To further test the strength of this hypothesis, I conducted a meta-analysis combining multiple studies across tropical and temperate study sites, and with many species tested. It revealed significant support for the Janzen- Connell predictions in terms of distance and density dependence. Using a phylogenetic comparative approach, I highlight how environmental adaptation affects dipterocarp distribution, and the relationships of plant traits with ecological factors and conservation status. This analysis showed that environmental and ecological factors are related to plant traits and highlights the need for dipterocarp conservation priorities. -

A total of 103 exotic plant species (99 species of angiosperms and 4 gymnosperms) belonging to 90 genera and 43 families were recorded through transect method from the study area. Among the exotics, tree species constitute the major category (46 species, 21 families) followed by shrubs (33 species, 18 families), herbs (21 species, 17 families) and climbers (3 species, 3 families). Mimosaceae family was represented by maximum (9) exotic plant species followed by Caesalpiniaceae (8), Myrtaceae (8) and Malvaceae (7). Most of the exotic plants were introduced in the eco-park after its establishment. Exotic tree species are given priority as the dominant plantation species in the eco-park area because of their short rotation, wider adaptability and faster growth. A total of 74 tree species (52 native and 22 exotic) belonging to 33 families were recorded through random sampling method in the eco-park. -

Contents Introduction 1 Lao Flora Listed by Lao Script 13-121 Lao Flora Listed by Genus and Species 123-238 Introduction This introduction1 provides a brief synopsis of the forest habitats and ecoregions found in Lao PDR, as well as an overview of the related research on plant taxonomy. This is followed by a description of the structure and contents of the present volume and a citation of sources used to compile the present checklist. 1. Forest habitats and ecoregions in Lao PDR 1.1. Forest habitats Forest classifications can be vegetation-related (which implies that the factors used to distinguish forests are the physiognomic or floristic characteristics of the vegetation), biophysically- and climate-related (where broad environmental or geographic characteristics become the distinguishing factors), or management- related (which involves utilizing combinations of vegetation and non-vegetation criteria). These modes of classification are scale-specific: while global-scale classifications are largely based on climatic criteria such as rainfall and temperature, classification systems used at country- or smaller regional-level scales emphasise floristic and physiognomic characteristics as well as physical site factors (Wong, Delang, Schmidt-Vogt, 2007). These latter variables were taken into account by the National Office of Forest Inventory and Planning (NOFIP) when it classified the forests of Lao PDR (Manivong and Sandewall, 1992).
