Commercial charcoal production has over time become an indispensable means of livelihood among rural settlers in Nasarawa State. However, charcoal production involves woodland exploitation which contributes to deforestation. Considering the growing significance of charcoal in rural and urban livelihoods in Nasarawa State, this paper analysed the preference of tree species and reasons among commercial charcoal producers in Nasarawa State in view of identifying endangered species and suggesting measures to ensure sustainability of the business. The study employed descriptive survey using both qualitative and quantitative data drawn from primary and secondary sources. Questionnaire was administered to 450 respondents randomly sampled from commercial charcoal producers drawn from 6 communities and 3 LGAs of Nasarawa State. Interviews and Focus Group Discussions were also conducted and the data obtained were analysed using descriptive and inferential statistics in Microsoft Excel and SPSS (version 23). A total of 22 tree species were identified as usable for charcoal production in the study area. Investigation into the producers’ preference of tree species showed that eight (8) were mostly preferred out of which Anogeissus leiocarpus (Marke) (57.3%), Erythrina senegalensis (Madri) (52.2%) and Prosopis Africana (Kirya) (49.1%) were among the top three. Marke, Kirya and Madri were the most preferred species in Akwanga, Doma and Karu production areas respectively. High charcoal yield, good combustion quality, high heat content of resulting charcoal, less ash production were the main reasons for their preferences. Most of the preferred tree species have been depleted to the point that they are no longer commonly found for use among commercial charcoal producers in the state. The most endangered species due to commercial charcoal production were Anogeissus leiocarpus (Marke), Erythrina senegalensis (Madri) and Prosopis Africana (Kirya). However, pressure is currently on Teminalia glocosece (Baushe/Uko), Andira inermis (Gwaska), Ficus Spp (Baure), Vitellaria paradoxa (Kede) and Gardinia aqualla (Gaude) due to the difficulties in finding the endangered ones which constituted the most preferred species among producers in Nasarawa State. It was recommended that state energy policies should incorporate a law recognizing charcoal as a key source of energy in the State, thereby encouraging investments in the activity of commercial charcoal producers. Furthermore, conservation plans and practical measures of replacing the extracted trees from woodlands/forests for commercial charcoal production should form the basis for license issuance for charcoal production.
