“…For example, the trunk is used as poles for poles and roofing material, the leaves are used for local fans, woven baskets and mats, and the fruits are used for medicine and food. The results further show that with the exceptions of Fabaceae, other families were poorly represented, which concurred with the observation made by Ikyaagba et al [15] and Nodza et al [9]. The implication of this result means a possible danger for the member species of the poorly represented families as the species belonging to those families are threatened and can go to extinction in the near future [15].…”

The study examined the diversity of vegetation (tree species and shrubs) for the preservation, utilization and conservation of tree species in Northern Yobe. A point centred quarter (PCQ) method was employed to study the vegetation structure in six randomly selected experimental sites across the three local government councils in Northern Yobe (Yunusari, Yusufari and Geidam). A total of 22 tree species and 7 shrubs belonging to 15 families were identified, with Fabaceae being the family with the highest number of tree species (5 members), and followed by Combretaceae, Mimosaceae, and Rhamnaceae each with 3 members. Aracaceae, Euphorbiaceae, Rhamnaceae, and Moraceae have 2 members each, while other identified families had a member of tree species. Specifically, Sodom apple was the dominant tree species based on Importance Value Indices (IVI) of 23.3, followed by Doum palm (22.0), then Guiera tree and Combretum species, each with IVI of 20.7, followed by Desert date (20.3), Thorn Acacia (19.9), and then Whistling thorn (19.3 as their IVI. The Diversity index was determined as 1, Simpson’s index of diversity was very low (-0.0082) and the species richness was 0.41. The low values indicate a less complex community, and the distribution pattern of the various parameters assesses was that of a typical Sahel-Savannah vegetation. Nevertheless, there was a large number of different tree species (29) recorded which implies many tree species are adaptable in the study area but only regenerated naturally without effort for intensive production. Therefore, the need of mass production of these trees in plantation and agroforestry for the conservation and utilization of the dominant (most adapted) tree species to halt environmental associated problems including desertification and erosion in the study area.

“…In Northern Nigeria alone, more than 80% of the population depend on fuelwood as their primary cooking and heating fuel. With the continuing growing population, and high human poverty index [9], it is expected that these figures will continue to rise [10][11][12].…”

“…Thus, various species are facing extinction (Bello et al2019;Bastías et al2022;Sharma et al2022). This threat is particularly acute for trees (Nodza et al 2013, Ibrahim et al2018) due to logging, excessive grazing, urbanization, agriculture (Nodza et al 2014;Łaska and Ige 2023) and exploitation of fuelwood and charcoal, which 70-80% of Nigerians depend on (Orimoogunje and Asifat 2015;Enyejo et al 2018).…”

Nigeria is one of the most floristic rich countries on the continent of Africa due to the variation in climate, which favors the growth of several species. Sadly, its biodiversity is one of the most threatened in the world, mainly due to deforestation and various unsustainable land use patterns, which are human activities. However, these anthropogenic activities are more prevalent in Nigeria's northern savanna zone (NSZ). In this study, we present the first regional conservation assessments and red listing of tree species in the northern savanna zone (NSZ) of Nigeria according to the International Union for Conservation of Nature (IUCN) criteria and categories. We recorded 31 tree species as the most utilized in the region. For the assessments, we provided the fundamental taxonomic information of each species, their local names, and their uses. This study provided the extent of occurrence, area of occupancy, population size and trend, description of habitats, and ecological requirements and discussion of the threats affecting each species and their habitats. We further inform conservation actions and research activities needed to ensure the future of the tree species and their sustainable uses. Overall, approximately 97% of the taxa were evaluated as threatened (41% as endangered, 31% as critically endangered, 24% as vulnerable, and 4% as least concerned). Therefore, we recommend the adoption of the risk status of the species to develop sound conservation strategies and measures for the management of flora in this inundated region.

“…Chrysophyllum albidum, commonly called cherry is a popular tropical fruit tree and widely distributed in the low land rain forest zones and frequently found in the villages and the fruit is common in rural and urban areas especially during the month of December to April. The fleshy pulp of the fruit (African star apple) is eaten while the seeds are used for local games or thrown away as wastes [11][12]. The seed shells can be picked and processed for other applications [13][14].…”

This research work investigates the use of locally sourced activated carbon as adsorbent in removing impurities and odoriferous substances from some petroleum fractions. The activated carbon was prepared from Crysophyllum abidum (cherry) seed shells. The seed shells were cracked to remove the seeds, washed, dried and pulverized. The powder was carbonized in a furnace at 500 0C, cooled and screened with a 100μm sized sieve. The carbonized powder was impregnated with phosphoric acid and sodium hydroxide in a mixture ratio of 2:1, stirred vigorously for activation and kept in an oven to dry at 110 0C for 2 h. The activated carbon was washed and dried to constant weight, and in comparison with the commercial type were characterized in terms of the moisture, ash, volatile matter contents, pH, bulk density, iodine adsorption number, silica content and percentage yield and gave 2.20%, 1.50%, 83.50%, 7.15, 0.45 g/cm3, 61.01 mg/g, 0.25% and 22.50% respectively. The activated carbon was applied in the purification of the petroleum fractions (dual purpose kerosene, DPK and premium motor spirit, PMS). The observed density, specific gravity (S.G), initial and final boiling points, flash point, ethanol content and research octane number (RON) of the petroleum fractions before and after the purification process were measured, the results showed that the treated DPK and PMS had improved properties due to the purification potentials of the activated carbons applied on them. The locally sourced activated carbon performed almost as well as the commercial type used, with slight inferiority in RON enhancement. Keywords: Chrysophyllum albidum seed shell, activated carbon, purification and petroleum fractions.
