Socio-economic factors influencing marketing of non-timber forest products in tropical lowland rainforests of south-western Nigeria^§

A number of factors persist to constrain the non-timber forest products (NTFPs) market and, by extension, its potential to contribute meaningfully to livelihood development and poverty reduction objectives. To better utilise the potential of NTFPs, it is important to have a better understanding of the key factors governing the success and failure of NTFPs trade. This paper reports on the market constraints and socio-economic factors that influence trade in five top-priority NTFPs within the tropical lowland rainforests of south-west Nigeria. The NTFPs investigated were bush mango (Irvingia gabonensis), African walnut (Plukenetia conophora), chew-stick (Massularia acuminata), fever bark (Annickia chlorantha) and bush pepper (Piper guineense). Field data were collected in 10 villages located within and around Omo and Shasha forest reserves using a household questionnaire survey. The results showed that seasonality, poor transport, lack of storage facilities and market information were the four main constraints influencing marketing and trade in the NTFPs. In addition, the level of education, gender (sex), household income, ethnicity, distance to the market and access to roads significantly influenced market knowledge and information among households involved in the trade of NTFPs. There is need to improve on the limited source of NTFPs information, enhance skills for product transformation, build innovative storage facilities, and develop the process of domestication and integration in traditional land-use systems.

The relative distribution was investigated of turaco-preferred food plants in the main forest and the forest fragments of Ngel Nyaki Forest Reserve in Taraba State, Nigeria. Data collection was carried out in three sections within the forest reserve and these include (i) forest fragment, (ii) within the main forest and (iii) the boundary area of the main forest. Ten plots with size of 25 m × 25 m were laid at an interval of 50 m in each of the three selected sites making a total of 30 plots for the sampling of turaco-preferred fruiting plant species. The numbers of fruiting tree species identified were 22, 25 and 24, and out of these only seven (31.8%), eight (32%) and six (25%) were preferred by turacos in the forest fragment, within the main forest and the boundary area of the main forest, respectively. The preferred fruiting plant species in the forest fragment was Syzygium guineense (48.6%), in the boundary area of the main forest was Ficus sp. (13.3%) and within the main forest was Polyscias fulva (3.9%). Many of the fruiting tree species in the boundary area and within the main forest were not preferred by turacos. There is a need for effective pro-conservative measures aimed at preserving the remaining forest patches (especially the forest fragment) of the reserve.


Ethnobotany and conservation of plant resources of Kainji Lake National Park, Nigeria

The study was conducted to generate baseline data for the conservation and sustainable use of woody resources in Kainji Lake National Park. The study objectives were to document local knowledge on uses, status and sustainable management of selected woody species. Using both ethnobotanical and quantitative ecological methods, the study was carried out in the Borgu sector of the park. A total of 37 plants species belonging to 18 families were selected using a ranking and prioritization scale. Family-Fabaceae was the dominant family in terms of number of species represented. The species are multipurpose and are exploited to satisfy different subsistence needs. Among the plant-use categories, medicinal uses ranked highest (38%) followed by edible plants (25%), miscellaneous purposes (24%), and construction (13%). In terms of species status, Detarium microcarpum Guill. & Perr. has the highest mean frequency of 68.9% and a population density of 3.036 + 1.7 individuals/ha. This is followed by Vitellaria paradoxa C.F. Gaertn. with 55.6% mean frequency and a population density of 2.143 + 1.7 individuals/ha. There was no significant relationship between the useful value of a species and its density rank (R= 0.047; R2 = 0.002; F= 0.783) in the study area. Thus, the study recommends a holistic approach that includes the involvement of the local people in the management of woody species.
