    Determining the local importance of non-timber forest products using two different prioritization techniques
    (2012) Amusa, T.O; Jimoh, S.O; Azeez, I.O
    Among the key uncertainties in the sustainable management of forest for non-timber forest products (NTFPs) is the high diversity of species and paucity of information on indigenous use pattern. In designing appropriate strategies for sustainable management of non-timber forest products, therefore, it is important to identify species with high local importance with the potential for sustainable and profitable extraction in a managed system. In this study, we assessed the use of two quantitative techniques including the Use-Value index (Phillips and Gentry, 1993) and Assigned-Value approach (Adeola et al., 1994), as procedures for prioritization of NTFP species in a tropical lowland rainforest ecosystem, Omo Forest Reserve (OFR), southwest Nigeria. A simple random sampling approach was employed to obtain data on the uses of NTFP species through semi-structured interview of 81 households in four communities within the reserve. Descriptively, the data were analyzed using frequency distribution, tables, chart and percentages. The Spearman correlation coefficient was employed to test for relationship between the values obtained for each of the two techniques. Results obtained for both techniques were fairly positively correlated (ρ = 0.59; P < 0.01), suggesting a cautious interchangeable use of the techniques for the same end. Based on our findings, we posit that in evaluating forest and NTFPs for local importance and use, the end objectives of such evaluation must be critically examined in the light of the interest of the different respondents’ group.

    Prevalence, utilization and conservation strategies for non-timber forest products in South western zone of Nigeria
    (2012) Jimoh, S.O; Amusa, T.O; Azeez, I.O
    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 further used to supplement the information collected. A simple random sampling technique was employed for the study. In Omo Forest Reserve (OFR), a total of seventy five species distributed in forty three families were recorded, while fifty six species in thirty one families were documented in Shasha Forest Reserve (SFR). Local end-uses of NTFPs include food and food supplements, snacks/sweeteners, wrapping leaves, soup and spices, beverages, dental care supplies, washing tools, roofing/construction materials, medicine and traditional rites items. While access to these resources is important to guarantee the socio-economic well being of the forest dwellers and communities, their sustainable management has not been taken seriously by policy makers thereby contributing to reduction of biodiversity and gradual but irretrievable loss of indigenous knowledge on the uses of most species. To ensure the sustainable utilization of NTFPs in these and similar tropical forest environments therefore, a number of conservation approaches are proposed.
