... value indices (IVIs) provide knowledge on important species of the tree community in the reserve. The list of species and their IVIs for first 10 most important species are shown in Tables 3 and 4. Based on IVI, the most important species in the intact part of the reserve were Combretum molle, Acacia hockii, Albizia grantibracteata and Entada abyssinica; while Combretum collenum and Terminalia glaucescens were the least ranked species among the first 10 species in the intact part of the reserve (Table 3). ...Context 2

... Dry forests represent about half of tropical and subtropical vegetation stretching from expanses of Africa, South America and the Asian Pacific [13]. Dry forests occupy areas receiving a tropical climate with precipitation ranging from 500 to 1500 mm per annum. ...
... In East Africa, dry Afromontane vegetation extend from the southern part of Arabian Peninsula to the eastern arm of the rift valley in the Drakensberg Mountains. These ecosystems have been reported to be rich in biological diversity and as centres of endemism with various range-restricted species [13]. Agoro-Agu CFR is one of the dry Afromontane Forest in Uganda at the border of Uganda and South Sudan, in Agoro hills. ...
... The vegetation of Agoro-Agu CFR is largely classified as dry Combretum savanna, wooded-savanna mosaics and dry highland forest dominated by Combretum molle R. Br ex G. Don, Vachellia hockii De Willd, Hagenia abyssinica Steud. ex. A. Rich and Terminalia glaucescens Benth species [13,16]. ...
Terrestrial ecosystems such as forest landscapes provide critical ecosystem services such as carbon sequestration, fundamental to people, society and the global climate change discourse. Just like moist forest, dry Afromontane forests too present a high carbon sequestration potential. However, Uganda has since not undertaken carbon stock inventories for these conservation areas, especially with dry Afromontane forests like Agoro-agu central forest reserve (CFR). So, their potential to capture and store carbon is yet to be understood in Uganda. This study was carried out to estimate carbon stock of Agoro-agu CFR, for its potential in climate change mitigation. A stratified sampling design was used, where 65 sample plots were established. Nested, fixed area circular sample plots with sub-plots of varying radii for tree height, diameter measurements and soil sampling, were used. The mean total carbon stock of Agoro-agu CFR was estimated at 606.7 Mg C ha−1, for which 409, 72, 124 and 0.24 Mg C ha−1 was stored as above ground carbon, below ground carbon, soil organic carbon and carbon in litter herbs and grass respectively. The study illustrates the carbon sequestration potential of the forest reserve for any results-based payment projects for climate change mitigation. This is mainly due to the interventions through collaborative forest management arrangements and the pro-poor reducing emissions from Deforestation and forest Degradation (REDD+) pilot project in the landscape. This however, calls for more multi-stakeholders’ collaboration from direct resource users to national level to enhance forest conservation and reduce forest degradation for sustainable resource benefits and other ecosystem services.

... The result showed that DBH has a signi cant in uence in carbon capture and storage of a forest over time. Most of these tree species were encountered in the higher elevation areas of the forest that are in undisturbed forest zone (Okullo et al., 2021). One of the impeding factors for forest growth and trees attaining a bigger diameter is rampant forest degradation and subsistence farming triggering deforestation, especially in the lower elevation of the forest reserve (Dibaba et al., 2019). ...

The high demand for firewood and charcoal has exerted high pressure on the indigenous trees in Uganda. Communities believe that the indigenous trees are better fuel sources despite limited evidence to support this claim. This study was carried out in 2021 to evaluate the fuelwood properties of selected indigenous tree species in comparison to three exotic tree species that have been promoted for use by refugees and host communities in Lamwo District of Northern Uganda. Wood samples were collected from three different locations from the study area in Lamwo District and transported to Gulu University for laboratory analysis of their physical and chemical properties. Data were analysed using one way analysis of variance (ANOVA) at 5% level of confidence and the means were separated using Tukey HSD test. Results showed that moisture content, fixed carbon, volatile matter, and Fuel Value Index (FVI) did not significantly vary among the indigenous and exotic tree species. Fuel value index was observed to be negatively correlated with moisture content of the wood, implying both species’ categories retard in fuel quality when their moisture contents increases. Overall, the results show that there were no significant differences in the FVI of all the indegeneous and exotic tree species investigated in this study. It is recommended that fast-growing exotic species such as Eucalyptus grandis , Caliandra calothyrsus , and Senna siamea that are grown in the region be promoted to ensure regeneration and reduction of pressure on the use of natural forest.
