Description

  • The study evaluates the potential for seedling recruitment of indigenous tree species in different types of plantations and secondary forest in western Kenya. The plantations are comprised of mixtures and monocultures of single or exotic indigenous tree species.
  • Two methods employed to determine the vegetation structure of each forest type were vertical foliage height using the Shannon diversity index and seedling mapping. Statistical analyses of data were done using ANOVA and PCA. 
  • The results showed significant differences in tree communities among the studied forest types. However, recruiting seedling communities showed smaller differences suggesting that tree plantations have the potential to develop into more natural forests over time.
  • Given the abundance of late-successional seedling species decrease from the natural forest towards monocultures and secondary forests at the expense of early-successional species, and with un-identical seedling communities authors confer that convergence of monocultures towards natural forests overtime.
  • In this study, distances (0.4-1.7km) to natural forest stands had no effect on seedling diversity or total number of individuals. This contradicts other studies showing that proximity to remaining natural forests promotes rapid seedling recruitment in nearby areas.
