ABSTRACT Effective management planning tools for forest require growth and yield functions that can produce detailed predictions of stand development. Models such as Gamma Distribution Function (GDF), Weibull, Beta, and similar functions have been used to predict growth and yield of forest stands. However, information on the use of GDF in forest management has not been fully documented. The development of a program using Java programming language for GDF to predict growth and yield of Tecton...
ABSTRACT Users of wood still have preferences despite increasing reduction in the availability of wood species.

ABSTRACT A laboratory evaluation of cashew nut shell liquid (CNSL) as wood preservative on sapwood of Triplochiton scleroxylon test blocks sawn into 20mm x 20mm x 300mm sizes against Trametes cingulata and Lentinus lepideus was studied using crushing method. The crude extract was diluted with n-hexane, volume for volume. Four levels of CNSL concentration were tested at 4%, 8%, 12% and 16%. The treated test blocks and control test blocks were exposed to the infection regions of the pathogens i...
ABSTRACT Non-Timber Forest Products (NTFPs) have been identified to contribute to community livelihoods. Such contributions are people as well as site specific and may be shortlived if continuous availability cannot be guaranteed. Information on the role of NTFPs in community livelihoods is crucial to their sustainable management; however, this role has not been properly documented in Taraba State. Therefore, contributions of selected NTFPs to community livelihoods in Taraba State were inves...
ABSTRACT This study was conducted to investigate the potential of tamarind fruits in jam production with a view to improving utilization efficiency of the fruits thereby adding value to the tree and encouraging its cultivation and sustainable management. The fruits for the study were collected from Bishop Ajayi Crowther University, in Atiba Local Government Area of Oyo town, Oyo State and Taironi Local Government Area of Kano State, Nigeria.

ABSTRACT Medicinal plants and plant-based medicines are widely used in traditional cultures all over Ghana and they are becoming increasingly popular in modern society as natural alternatives to synthetic chemicals. This paper studied the ethnobotany of medicinal plants through a socio-economic survey. Seed germination experiments were also carried out on selected medicinal plant species. It was found that the herbal medicine industry was a major source of income for 82% of the respondents. A...
ABSTRACT Upsurge in population has resulted in pressure on many tree species including Vitellaria paradoxa C.F.Gaertn.and Parkia biglobosa (Jacq.) Benth. These species are highly valued for their socio economic potentials. The study therefore assessed the contribution of V. paradoxa and P. biglobosa to rural livelihood in Oyo State, Nigeria with a view to generating information on the socio-economic values of the species to the rural communities. Stratified sampling technique was used to div...
ABSTRACT The Kakum Conservation Area (KCA) was part of a system of social cohesion within a culture. That environment created a sub-culture providing for the people food, clothing and shelter among others. By the creation of the conservation area, restrictions were imposed on the communities around it. There is therefore a persistent attempt by the communities to illegally enter the restricted area in the quest to satisfy their livelihood needs. This work examined the conservation and livelih...
Abstract The study was carried out to investigate the prevalence and utilization of non-timber forest products (NTFPs) plant species in Omo and Shasha Forest Reserves, Southwestern Nigeria. Data were obtained through the use of structured questionnaires administered to households in forest communities. To complement information from the household survey, focus group discussions (FGDs) were also carried out in each of the sampled communities. In-depth interview (IDI) of forestry staff was fur...

ABSTRACT Sustainable forest management, when backed with appropriate policy instruments and legal administration will promote improved livelihoods of forest dependants without sacrificing inherited forest biodiversity and its future potential. These are contradictory demands from different stakeholders. While meeting livelihood expectations of forest dependants may seem an affective issue, it may become substantive when their needs are not adequately planned for and they have to meet it withi...
ABSTRACT The preservative treatment of non-durable lignocellulosic materials, such as Bambusa vulgaris (bamboo) enhances its service life. Thermally modified lignocellulosic biomaterial is better than chemically treated products because it is environmentally friendly. However, there is a dearth of information on the characterisation properties of thermally modified Bambusa vulgaris. This study was therefore conducted to characterise the properties of thermally modified Bambusa vulgaris. One ...
