Volume And Biomass Estimation Models For Tectona Grandis Grown At Longuza Forest Plantation, Tanzania

ABSTRACT  Quantifying tree volume, biomass and Carbon (C) stocks potential of tree crops by using allometric models is vital for understanding the contribution of forests on climate change mitigation effort. The existing allometric models for accurate estimations of total tree volume and total tree biomass for Teak (Tectona grandis) has limitation of application such as models being developed from few sample trees for model development and covered narrow range of diameters and excluded trees...

Determining the Local Importance of Non-Timber Forest Products Using Two Different Prioritization Techniques

Abstract Among the key uncertainties in the sustainable management of forest for non-timber forest products (NTFPs) is the high diversity of species and paucity of information on indigenous use pattern. In designing appropriate strategies for sustainable management of non-timber forest products, therefore, it is important to identify species with high local importance with the potential for sustainable and profitable extraction in a managed system. In this study, we assessed the use of two q...

Models For Estimating Tree Volume, Above- And Belowground Biomass For Acacia-Commiphora Woodlands In Same District, Tanzania

ABSTRACT Reduced Emissions from Deforestation and Degradation (REDD) framework demands measuring of carbon stock changes. In most cases, estimates of carbon stocks rely on volume and biomass estimation allometric models. Although species-specific and some generic models for biomass and volume estimation have been developed for some vegetation types such as Miombo woodlands, their use in Acacia-Commiphora woodlands in dry areas is questionable as they comprise short-height trees with small to...

Factors Affecting Pine Resin Productivity And Its Potential As Source Of Revenue In The Forest Sector Of Tanzania: A Case Study Of Sao Hill Forest Plantation

ABSTRACT  Tanzania is rich in pine forests which have the potential to produce valuable resin. In recent years Tanzania has embarked on commercial resin tapping at Sao Hill Forest Plantation. However, current information on resin tapping in the country is scanty and unreliable. Knowledge of factors that affect resin productivity is important for it is those factors that can be manipulated to enhance resin yield. The focus of this study was to fill this knowledge gap by exploring some pine tr...

Effects Of Forest Cover Change On Carbon Stock In Miombo Woodlands: A Case Of Mbiwe Forest Reserve In Mbeya Region, Tanzania

ABSTRACT Most changes in forest cover affect the amount of carbon held in vegetation and soil, thereby, either releasing carbon dioxide (a greenhouse gas) to, or removing it from the atmosphere. A study on effects of forest cover change on carbon stock in miombo woodlands was carried out in Mbeya region at Mbiwe Forest Reserve. Landsat MSS, TM and ETM+ image data acquired on June 1984, June 1990 and June 2013 were obtained and used for forest cover change analysis. Inventory data on systemat...

Verification Of The Extent And Expansion Potential Of Forest Plantations In Tanzania

ABSTRACT The study on the extent and potential of forest plantation in Tanzania was carried out in three selected zones of Southern highlands, Lake and Northern. It was specifically conducted to verify the current area of forest plantation under different ownership, assess the expansion potential of forest plantation under different ownership, and assess factors affecting expansion of forest plantation in Tanzania and propose interventions measures. Primary data were collected using prepared ...

Utilization Of Mangrove Forest Resources For Human Livelihoods In Uzere, Delta State, Nigeria

Abstract  The study was carried out to assess the various ways Uzere mangrove forest is utilized by the forest edge communities. Data were obtained from 300 residents within the three communities in Uzere Kingdom using systematic random sampling. The study employed questionnaires to elicit information on the uses of the mangrove forest, the socio-economic factors that influence uses. Data obtained were analysed using simple statistics and correlation analysis. All the respondents use the for...

Selected Wood Properties Of Two Lesser Known And Lesser Utilized Indigenous Agroforestry Species From Kilosa District, Tanzania

ABSTRACT This study was conducted to determine basic density, fibre length and some strength properties of Lonchocarpus capassa and Combretum zeyheri suitable for growing under agroforestry systems in Kilosa district. A total of three 13 year old trees from each species were sampled in Rudewa Gongoni village for the study. Diameter at Breast Height (DBH) and height of each tree were measured. The trees were then felled and cut into logs. Each log was cross cut into three 1.5 m billets represe...

Comparative Study Between Government And Private Forest Plantations Management Practices: Case Studies Of Sao Hill And Green Resource Forest Plantations, Mufindi Iringa Tanzania

ABSTRACT The study was carried out in Sao Hill and GRL for comparison of management practices applied between government and private forest plantations. The study focused at identifying existing management practices, examining cost involved in forest management practices, assessing forest stand parameters and identify challenges facing management practices in Sao Hill and GRL in five years from 2012 to 2016. Data were collected through direct measurement in the forest stand parameters, struct...

Feasible media mix for dissemination of forest conservation support information (FCSI) in South Western Nigeria

Abstract The paper reports tile potentials of media mix in use for agricultural information dissemination as applied to dissemination of information on forest conservation and sustainable land use practices in three southwestern states of Nigeria. It covered enclaves in Sliasha and Oluwa forest reseives in Oshun and Ondo states respective&, as well as settlements surrounding Old Oyo fictional Park h Oyo State. Z'ie media considered were traditionai and eierironic/prinnt Primary data were sour...

Felling Induced Dynamic Stresses In Some Tropical Hardwoods From Nigerian Lowland Rainforest

ABSTRACT A study was undertaken to estimate the magnitude of dynamic stresses (MDS) induced in some mature tropical hardwood species during felling operation and their effect on the harvested wood. Five areas in Shasha forest reserve, Osun State, Nigeria were selected as the study sites because of the prevalent high. Two hundred and eighty nine trees represented by nine different species were studied. The species are Afzelia africana, Nauclea diderrichii, Terminalia superba, Khaya ivorensis, ...

Challenges Of Forestry Incarbon Trading

ABSTRACT  Forests play central and primary roles in the mitigation of climate change. Forests are important carbon pools which continuously exchange C02 with the atmosphere, due to both natural processes and human action. At the global level, 19% of the carbon in the earth's biosphere is stored in plants, and 81% in the soil. In tropical forests, approximately 50% of the carbon is stored in the biomass and 50% in the soil (Karsenty et al, 2003). Wood products derived from harvested timber ar...

Effect Of Process Variables On The Strength Properties Of Veneer Laminated Cement Bonded Particle Board From Mixed Tropical Hardwoods

ABSTRACT Modulus of Rupture (MOR) and Modulus of elasticity (MOE) of veneer laminated wood cement panel were evaluated. the boards were made of 3 layers comprising . 1.5 mm thick mixed hardwoods sawdust for the two surfaces, and 9mm thick core layer made of plantation grown Gmelina arborea flakes. Three varjabIes were investrgated namely: .Demity at three lev& (1000 w31,10 0kg/m3a nd 1200 kgl m3), Cam& wood ratios of2,5:1.0,2.75:I.O and 3.0:l.O and glue spread of 1.02 kgh2, 1.43 kg/m2 and 1,7...
