Item Population pattern and phenological behaviours for selected medicinal plants in Nigeria; implications for ex-situ conservation(2013) Oni, P.I.; Jimoh, S.O.; Adebisi, L.A.Recent developments indicated increasing gene-pool depletion for most medicinal plants in Nigeria despite their pharmaceuticals and therapeutic potentials. Initial socio-economic study involving three countries (Nigeria, Ghana and Republic of Benin) identified ten most frequently used medicinal plants. This list was superimposed on a vegetation map of Nigeria for the production of a distribution map ahead of an eco-geographic survey for population and phenological studies. Sample sites were defined in east-west directions under different vegetation and land use types. Sample sizes of 50m x 50m quadrant were selected across the vegetation and land use types. Altogether 55 samples quadrats were recorded across the zones; Lowland rainforest (20), Derived savanna (16), Sudan savanna (13) and Guinea savannah (6). A total of 196 individuals were recorded across the four ecological zones, rainforest 66 (33.67%) and least in Sudan savanna 13 individuals (6.63%). On land use basis, plantation forest recorded the highest in the lowland rainforest zone and least in sacred groove with similar trend in Derived savanna. In Guinea savanna, farm lands had the highest number of individuals while forest plantation accounted for the highest in Sudan savanna. Flowering duration varied greatly, ranging from (8.42 ±0.83) days to (45.25 ±5.77) days. Fruiting patterns ranged between (14.44± 4.28 to 145.87± 8.76) days. The need for adequate phenological information ahead of ex-situ conservation programme is desirable. Low stocking density observed across the range and land use types is implicated for holistic conservation strategies and sustainabilityItem Sustaining the Roles of Non-Timber Forest Products in Rural Poverty-Reduction and Household Food Security in Nigeria(Medwell Online, 2006) Jimoh, S.O."Forest outputs are broadly classified into timber and Non-Timber Forest Products (NTFPs). While the timber component has been widely acknowledged as great contributor to both national and local economies, the equally important non-timber component had received little attention from social scientists and development planners until very recently. Non-timber forest products are all those goods and services of biological origin obtained from forests or associated ecosystems, which contribute directly or indirectly to human welfare. The non-timber forest products contribute immensely to household food security and income generation in Nigeria. Hence they play a significant role in rural poverty reduction. In Nigeria poverty, incidence had increased from 27.2% in 1980 to 65.6% in 1996. This disturbing trend has prompted the federal government and international agencies to formulate various programs aimed at reducing the poverty incidence in the country. Many of such programs have however failed to achieve the desired objectives because they failed to understand the intimate relationship between the rural people and their immediate environment. The poor depends largely on land and various plants and animal resources obtainable from it. The closely interwoven relationship between the people and their biotic environment should be carefully understood and adjusted in such a way that the ecosystem balance is sustained. This study examines the significant roles played by non-timber forest products in rural livelihood sustenance in Nigeria. Various strategies for sustainable production and utilization of the products are discussed. "Item Non-Timber Forest Products in Phytomedicine and Culinary Uses(The Forestry Association of Nigeria, 2005) Jimoh, S.O.This paper is focused on medicinal and culinary uses of non-timber forest products. A medicinal plant is any plant which one or more of its organs contain(s) substances that can be used for therapeutic purposes or which are precursors for the synthesis of useful drugs. Culinary' plants on the other hand are those plants or products thereof used to flavour foods or beverages before, during or after their preparation. There is no clear distinction between spices and condiments. In the same vein, the distinction between food and medicinal plant is not clear-cut as many edible plants are also used in traditional medicine. Examples of these include: Vernonia amygdalina; Pterocarpus spp. Vitex doniana, Gongoronema laitfolium, Ocimum gratissimum, Crassocephalum rubens; Xylopia aethiopica; Piper guineense and Lactuca taraxacifolia. An attempt is made here to present information on some common medicinal plants with emphasis on their common, scientific and family names; ailment(s) they are used to treat, part(s) of plant used and the relevant authority. Culinary plants including spices and aromatics and the problems militating against the sustainable utilization of these valuable products are discussed while possible conservation methods are proposed.
