Occurrence of Nodulation in Unexplored Leguminous Trees Native to the West African Tropical Rainforest and Inoculation Response of Native Species useful in ReforestationBackgroundFew studies examine the ability of leguminous tree species to nodulate and fix atmospheric N, especially symbiotically with rhizobia; this study seeks to fill that research gap. The occurrence of nodulation was determined in 156 mature leguminous species growing in 6 natural forest areas in south-eastern Guinea and an in situ experiment of rhizobia inoculation was performed on 8 selected tree species.

Does Weeding Promote Regeneration of an Indigenous Tree Community in Felled Pine Plantations in UgandabackgroundThis study evaluates a management scheme to cut vines, grasses, and shrubs to promote regeneration of indigenous trees subsequent to removal of plantation softwoods over a period of 3 years in Kibale National Park, Uganda. Research Goals & MethodsSampling of tree species from seedlings to adults were identified to species. The diameter of all stems more than 1.2m tall were measured at that height (DBH). The plots were subjected to subsequent cutting of weeds on average once every 7 months. Available with subscription or purchase |
Changes in Plant Species Composition Within a Planted Forest in a Deciduous Agroecosystem in GhanaBackgroundEarly-successional tree plantations can promote regeneration of second-growth mixed-species forests. While non-native species have been studied for their role in enabling second-growth regeneration, this study surveys understories of plantations of trees native to Ghana in a post-maize site to explore the suitability of native trees for promoting second-growth regeneration.

Effects of Ground Preparation and Microenvironment on Germination and Natural Regeneration of Juniperus procera and Afrocarpus gracilior in EthiopiaBackgroundThis study assesses the net effect of seed supply and seedbed changes on germination and natural regeneration of J. procera and A. gracilior in the Afromontane forests of Ethiopia.

Status of Indigenous Tree Species Regeneration under Exotic Plantations in Belete Forest, South West EthiopiabackgroundThis study assesses the diversity and density of naturally regenerated woody species under the canopies of exotic plantations adjacent to natural forests in a moist montane forest type in Southwest Ethiopia.

Indigenous Trees in West African Forest Plantations: The Need for Domestication by Clonal TechniquesbackgroundThis study evaluates native species tree plantations across West Africa by summarizing existing information on the yield of those plantations, with particular focus on the Cameroon Forest Management and Regeneration Project. It considers the potential for vegetative propagation and clonal selection to increase growth rates and marketability of native species. Open access copy available |
Native Forest Regeneration in Pine and Eucalypt Plantations in Northern Province, South AfricabackgroundThis study assesses understory colonization by indigenous plant species in exotic tree plantations established on grasslands growing adjacent to native mixed evergreen forest in Northern Province, South Africa.

Native Tree Species Regeneration and Diversity in the Mountain Cloud Forests of East AfricabackgroundThis study evaluates the diversity of native species regeneration within 3 native and exotic forest plantations of the indigenous forests of Tatia Hills, East Africa. Research Goals & MethodsResearchers monitoried species diversity, richness and similarity of regenerated species between exotic plantations of pine, eucalyptus and cypress, as well as between native and exotic forests.

Regeneration of Indigenous Trees in Mgahinga Gorilla National Park, UgandabackgroundThis study examines the dominant exotic species, their distribution and effect on the regeneration of indigenous tree species in the formerly encroached area of Mgahinga Gorilla National Park, southwestern Uganda. The 4 habitat types examined were exotic woodlots, old croplands and natural forest habitat. Research Goals & MethodsIndigenous species diversity was assessed by systematic sampling of the vegetation and soils in transect plots. Available with subscription or purchase |
High Seedling Recruitment of indigenous Tree Species in Forest Plantations in Kakamega Forest, Western KenyabackgroundThe 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. Available with subscription or purchase |
