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...
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...
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...
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...
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 ...
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...

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...
