Development of value-added products from any unutilized woody or non-woody material can play a vital role in economic development and also in forest resources conservation of any country. In this study, the suitabilities of planer waste and chips of Bambusa balcooa and Bambusa vulgaris, two locally grown bamboo species of Bangladesh, were investigated for the production of particleboard. The planer waste is a kind of shavings obtained during planing operation of bamboo splits for making rectangular strips of uniform thickness. Urea formaldehyde glue was used as a binder. Particleboards (12 mm thickness) were made from each type of the material applying 3.5 N/mm2 pressure at 140 °C press temperature. The panels were tested to determine bending strength, modulus of elasticity, tensile strength, thickness swelling and water absorption. The variation in particle geometry of the raw materials significantly influenced the physical and mechanical properties of particleboard. The chips showed better strength properties compared to planer waste. B. vulgaris produced better and well glued particleboards compared to B. balcooa because of its superior gluability. The product could be used for indoor application especially as furniture component. Further research on the improvement in dimensional stabilization of product is needed. © 2010 Elsevier Ltd.

A study of salt tolerance was carried out on germination, survival and height growth performance of important mesophytic species such as Acacia auriculiformis, Acacia hybrid, Artocarpus heterophyllus, Albizia procera, Albizia lebbeck, Acacia nilotica, Achras sapota, Casuarina equisetifolaia, Emblica officinalis, Leucaena leucocephala, Samania saman, Swetenia macrophylla, Terminalia arjuna, Tamarindus indica, Terminalia bellirica and Thespesia populnea in nursery stage using fresh water and salt (NaCl) solutions of 10, 15 and 20 ppm. Effect of salt on germination, survival performance and height growth performance were examined in this condition. Based on the observation, salt tolerance of these species has been determined Acacia auriculiformis, Acacia hybrid, Achras sapota, Casuarina equisetifolia, Leucaena leucocephala and Tamarindus indica has showed the best capacity to perform in different salinity conditions. Acacia nilotica, Emblica officinalis, Thespesia populnea has performed better. Albizia procera, Samania saman and Terminalia bellirica, germination and height performance showed good but when salinity increases survivability were decreases. © 2013 Asian Network for Scientific Information.

Mesophytic species such as Acacia nilotica, Albizia labeck, Albizia procera, Casuarina equisetifolia, Pithocellobium dulche, Samanea saman and Thespesia populnea were raised in the western coast of Char Kashem under Patuakhali district of Bangladesh. After seven years of planting highest survivability was found in A. labeck followed by P. dulche, C. equisetifolia, S. saman, A. procera, A. nilotica and T populnea. The mean maximum diameter at breast height was found in S. saman followed by C. equisetifolia, A. procera, A. labeck, P. dulche, A. nilotica and T. populnea. The maximum plant height was found in C. equisetifolia followed by S. saman, A. procera, T. populnea, A. nilotica, A. labeck and P. dulche indicating suitability of all the seven species for plantation at Char Kashem.

During recent years, the Government of Bangladesh, Non-Government Organizations (NGOs), semi-government organizations, private organizations and individuals have established a large number of plantations under different programs viz. social forestry, agro-forestry and avenue plantations with indigenous and exotic tree species without considering their habit and habitats. Along with the indigenous species like Albizia procera, Albizia lebbeck, Mangifera indica, Azadirachta indica, Gmelina arborea, Trewia nudiflora and Artocapus heterophyllus and many exotic species e.g. Swietenia macrophylla, Albizia saman, Dalbergia sissoo, Eucalyptus camaldulensis, Acacia auriculiformis, Melia sempervirens, Acacia mangium etc. have been planted randomly. With increasing trend of climate-induced floods, millions of trees have been dying due to floods and water-logging. The most affected species are Dalbergia sissoo, Albizia saman, Acacia auriculiformis, Acacia mangium and Artocarpus heterophyllus etc. This situation has caused severe impacts on socio-economic conditions of Bangladesh. The impacts involved a significant loss in terms of investment, biodiversity and afforestation program. Little investigations have been conducted to find out the causes of the deaths and also to find out the suitable adaptation practices to reduce impacts of floods on trees. This synthesis focused on the impacts of floods on plantations and also assessed the potential role of traditional forest management practices in addressing the effects flooding on forests in Bangladesh. The study added important information and revealed knowledge gaps on the causes of large forest deaths. It also provided recommendations for policy on the establishment of frequent floods resilient tree crop plantations. © 2015 The Authors.

This paper provides ethno-botanical information on 70 plant species under 36 families and these species were in common use among the Bwam, the Marma, the Murang and the Tanchangya communities of Bandarban hill district. Ethno-medicinal uses along with their scientific names, families, local names, voucher numbers and uses are enumerated. Quantitative analysis shows that the Marma tribe uses the higher number of species followed by the Tanchangya, the Murang and the Bwam. Similarity index indicates that the Marma, the Tanchangya and the Murang have higher similarities for ethno-botanical knowledge among four tribes. The most widely used medicinal plants are Cassia obtusifolia L., Centella asiatica (L) Urban., Costus speciosus Smith, Emilia sonchifolia DC., Litsea glutinosa (Lour.) Roxb., Melothria indica Lour. and Premna esculenta Roxb. Fever, cough, menstrual problem, diarrhoea, dysentery, tumor and skin diseases seem to be common problems treated using plants by the tribal communities in Bandarban district. © 2012 Bangladesh Association of Plant Taxonomists.
