Abstract: A Study on woody plant diversity and structure were conducted on Telet Forest in Sayint District, South Wollo Zone of Amhara Region, Ethiopia. Sixty four main quadrats of 20m × 20m with which five small quadrats of 5mx5m were systematically laid along transects. In each main quadrat, all tree/shrub and saplings and seedlings of woody species within the subplots were counted and recorded. Tree height of plants was also measured using a meter-stick so as to categorize plants into he...

Abstract: Environmental friendly pre-treatment of fibre has been lately adopted by many researchers worldwide but not fully understood. Although various chemical modifications of fibre through several chemical treatments have been explored, but less has been done on lower sodium hydroxide (NaOH) concentrations. This paper investigated the effect of thermalization at 115 C and lower NaOH of concentrations (1, 3 and 5) effect on mukwa wood flour as a way of minimizing chemical impact on possib...
INTRODUCTION Wood-cement bonded particleboard, was originally invented in Germany about eight decades ago. Since then it has been gaining acceptance in many parts of the world as a sheet element or the building construction-industry. The" interest in the board can be associated with a number of factors. It is highly resistant to flre, insect aud fungal attack and has excellent weather ability and good accoustic insulation properties (Deppe,1974; Dinwoodie, 1978;1981). With respect to the afor...
Abstract Household livelihood across Africa 50 years after independence have recorded lean improvements especially in terms of access to essential production inputs. Household rate of land access, means of access, Household rate of land access, means of access, welfare and investment capacities, land cost and the linkage between access to land and the above measured parameters were investigated using a set of questionnaires administered to urban and rural settlements. Descriptive results show...
Abstract Public sector dominance of forestry practices across the globe impedes realization of local and international forestry development targets despite huge local and international investments in the subsector. The need for private forestry practice as compliment to public initiatives on forestry development therefore becomes imperative. This paper reports the bottlenecks for private farm forestry practices among households in the humid zone of Nigeria where environmental hazards necessit...
ABSTRACT The purpose of this study was four-fold: First, to estimate merchantable logging residues left in the forest after logging; second, to investigate the natural durability of stem and branch wood of five species; third, to compare the bending strength of solid and finger-jointed lumber; and finally to investigate the influence of anatomical properties on natural durability and mechanical properties of wood. The five wood species were Entandrophragma cylindricum (sapele), Entandrophrag...
The huge quantity of waste generated from industries pose a major problem of proper and adequate treatment. Many methods have been discovered for proper waste management so as to convert waste into reusable by-products. This research highlights the use of one of the simple and easy methods-Effective Microorganism (EM) Technology. Here, microorganisms from natural sources are used to convert different types of wood residues from a large wood industrial complex into a reusable form. It has ...
Large amounts of lignocellulosic waste are generated through forestry and agricultural practices, paper-pulp industries, timber industries, and many agro industries. They pose an environmental pollution problem. One of the most economically viable processes for the conversion of lignocellulosic wastes into useful products is the use of earthworms. This process by which earthworms are used to convert organic materials is known as vermicomposting. In the present study, vermibeds were prepar...
The present study was carried out with an objective to analyse the feasibility of composite production using sawdust, boiler ash and cement as raw materials. The study investigated various combinations of sawdust, boiler ash and cement as the raw materials for composite brick production. A total of 24 bricks were made on volume ratio basis of sawdust to cement (1:3 and 1:2), boiler ash to cement (1:3 and 1:2) and sawdust, boiler ash to cement(1:1:1 and 1:1:2). The bricks produced were ...
This article summarizes the present status and challenges of academic programmes in the field of Wood Science and Technology (WST) in Indian universities and other institutions, with special emphasis to post graduate education. Though the WST education has been running since several decades in India, there is very slow improvement in terms of the number of institutions offering this programme, when compared to many other professional courses. Now there are only 8 institutions in the country...
ABSTRACT Nigeria’s textile industry is the second largest textile industry in Africa employing thousand of workforce and millions of indirect workers. It has been identified as the dependable employer of labour and source of financial security for most Nigeria youths the sector employed 25% workers in the nation’s manufacturing sector. The textile industry has one of the most complicated industrial chain in the manufacturing industry. This study however, is aimed at known the impact o...
ABSTRACT Trees have been an important aspect of human settlements from history in the days of our forefathers and only a few of the urban dwellers have recognized the benefits gotten from these trees. Urban trees has several benefits it provides to the society, including physiological benefits, aesthetic benefits, prevention of land degradation, reduces increased noise level, social and ecological benefits, provision of fruits, nuts, leaves, fuel wood, fodder, vegetables, shade, and windbreak...
The excellent properties of wood are widely recognized due to the fact that it has been used in the manufacture of structures and shelters from the earliest ages of man. The demand for forest and forests product keeps on increasing as the forest estate is drastically reducing with increasing population and civilization. The increase in the demand of forest and its products in Nigeria has led to the over-exploitation of the Natural Forest and thereby affecting has abundant effect on deforestat...
Abstract: This study was carried out to examine the physical and mechanical properties of thermally and chemically modified Leucaena leucocephala wood. Sample planks were obtained from Akure and reduced to defect free samples of 20mm × 20mm × 60mm. Wood samples were oven dried at 105 oC and cooled in a dessicator to a constant weight before the thermal treatment. Heat treatment of wood was carried out in a Muffle Furnace at 140 0C, 160 0Cand 180 0C for 1hr and 2 hrs. Butyl Acetate was u...
