Mount (Mt) Elgon forest in western Kenya is important for biodiversity, environmental protection and socio‐economic development. Characterizing forest conditions is essential for evaluation of sustainable management and conservation activities. This paper covers findings of a study which determined and analysed indicators useful in monitoring disturbance levels in the Mt Elgon Forest. A systematic survey was carried out and covered 305 plots of 0.02 ha and 250 smaller nested regeneration plots along 10 belt transects that were distributed in five blocks within the moist lower montane forest type. Collected and analysed data include types of disturbance, tree species composition, abundance and logged species. Correlation breakdown among disturbance types revealed that, paths were indicators of the number of tree harvesting sites (rs =1.00, P < 0.01) and of de‐vegetated areas through grass harvesting (rs = 0.90, P = 0.04). Solanum mauritianum Scop. was an indicator of old‐charcoal production sites. Logging targeted 13 tree species and harvested trees with diameter at breast height above 20 cm. The most exploited species were Olea capensis L. and Deinbolia kilimandscharica Taub. All exploited species had low regeneration but tree regeneration was not an effective indicator of logging.
A study on population density, structure, distribution and early growth characteristics of Tarchonanthus camphoratus was carried out on a Tarchonanthus-dominated woodland. A line plot transect 4 km in length was laid out in a woodland along the altitudinal gradient capturing most of the observed vegetation variation. In total 34, 20 · 20 m plots were evaluated for their horizontal population structure and species composition. In addition, six more plots dominated by Tarchonanthus were monitored for coppice and shoot development for a period of 8 months. Understanding of growth and population characteristics of the dominant species in woodland is necessary for its effective management. Results indicate that the woodland can be delineated into three distinct stands by using cluster analysis based on location and composition. The diameter size class distribution of the woodland follows a reverse J curve, which indicate a normal uneven-aged forest. Tarchonanthus camphoratus has a high regenerative power after cutting or burning, which indicates its high potential for sustainable management. It was concluded that the woodland could be stratified into distinct stands for management. Permanent sample plots should be established to determine the sustained yield, as size-class distribution alone is insufficient. A management and utilization schedule based on distinct stands is recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
