Abstract:
The overall objective of this study was to analyze the trend in occurrence and distribution of
Mvule tree (milicia excelsa) species in Namutumba Sub County.
The study was cross sectional and used both qualitative and quantitative approaches to collect data, analyze and present it. The methods of data collection used were interviews questionnaires, field observations and mapping using GPS. The data was collected and analyzed using excel, stat spss, arc map, llwis and Arc view, which facilitated the formation of frequency tables, pie charts, shape files and point maps. The study was based on primary data collected through GPS tracking, field observations, the use of questioners, interview guides that were randomly distributed to the respondents in the different cluster areas.
From the findings, it was recognized that abundance of Mvule. tree species is decreasing at a higher rate. Over exploitation of this tree species for wood, charcoal wild fires and clearance of agricultural land has aggravated a loss. Furthermore, natural occurrence of pests and diseases especially gall fly has retarded the growth cycle of the young species, In. addition presence of early and late bright has hindered the rise of this tree species in nurseries. Besides, the results indicated that most of the trees are young from the seedlings widely distributed on individuals own land and few mature trees located at health centers, trading centers; administration grounds and cultural sites. This implies that the source for seeds is still minimal.
Prospects
Mvule belongs to the most valuable timbers of Uganda, due to its attractive appearance, durability, stability and good working properties. At present its exploitation is not sustainable in most of Uganda. Therefore, it requires protection and exploitation has to be limited if it is to become sustainable. Plantation is difficult due to a pest problem. The identification of sources of resistance to the Mvule gall fly deserves high priority and can possibly be complemented by the development of effective control methods, especially the use of natural: parasites or predators of the Mvule gall fly.
