Item Management of indigenous medicinal plants in Nigeria using phenological information(Academic journals, 2014) Oni, P. I.; Jimoh, S. O.; Adebisi, L. A.Available information on medicinal plants indicates habitat loss and has heightened the need for more proactive conservation strategies. Conservation efforts in this direction resulted in an eco-pharmacological survey in the West African sub-region by three countries (Nigeria, Ghana and Republic of Benin) to assess frequently used medicinal plants. The result of the socio-economic study based on utilization pattern regionally was used to produce a list of ten topmost frequently used and mentioned medicinal plants regionally and was subsequently adopted for the eco-pharmacological study in Nigeria. The list was super-imposed on a vegetation map of Nigeria for study sites selection in the species range. Selection criteria were based on the presence of at least one or more members of the medicinal plants in each location. Subsequently these plants were monitored range-wide for phenological behaviors for two seasons (dry and raining seasons) for two consecutive years. Findings indicated that the ten medicinal plants belonged to nine taxonomic families and are represented in the three plant habits. Flowering was majorly a dry season event (November to February) extending to early rains (March to April) in the species of the southern range (lowland and derived ecozones). Fruiting was typical of early rains increasing northwards (March to July). For short duration flowering species (Pcynanthus angolensis, Alstonea bonnie and Rauvolfia vomitoria), fruiting occurred late in dry season (December to February). Mean flowering duration ranged between (9.45 ± 1.73 to 45.68 ± 4.77) days, while mean fruiting duration ranged between (15.22 ± 2.15 to 145. 87 ± 8.59) days. Phenological charts were used to depict the phenological trends for the different species. The provision of this information offers a useful tool-kit for medicinal plants genetic resources monitoring, management and appropriate conservation strategies in NigeriaItem Non-Timber Forest Products and Sustainable Forest Management in Nigeria(Forestry Association of Nigeria, 2005) Jimoh, S.O.; Adebisi, L. A."The paper examines the potential roles of non-timber forest products in sustainable forest management in Nigeria. It is observed that there are numerous non-timber forest products in the various ecological zones of the country. Presently the situation of the nations’ forests is far from being sustainable. Case's of illegal felling, forest encroachment, poaching and outright de-reservation of gazetted forest reserves are very rampant. The forest reserve communities have become very hostile and uncooperative towards forest management and conservation programmes. Multiple-use forest management has been found very useful in achieving sustainable forest management in many parts of the world. The country’s rich biodiversity, prevalence of consequences of environmental mismanagement, insecurity of forest properties, and the nature of traditional indigenous land resources management systems in the country all provide a useful platform upon which the development of multiple- use forest management could be built. Since Multiple-use forest management involves the management of forests such that all its resources are considered in planning the management, it is obvious that non-timber forest products have a crucial role to play in sustaining the resources of our forests. To make progress in this direction, it is necessary to first carry out a needs survey of forest communities, undertake detailed resource inventory, hold stakeholders’ meetings and engage in both socio-economic and ecological studies so as to evolve a socially acceptable, economically viable and ecologically sound management technique."
