Forest Restoration in Abandoned Agricultural Land: a Case Study from East Africa

background

This study quantifies the pattern of forest recovery following clearing and 3 years of cultivation of an abandoned agricultural land adjacent to a 300ha relatively undisturbed natural forest in a moist-evergreen forest in Kibale National Park, Uganda.

Does Weeding Promote Regeneration of an Indigenous Tree Community in Felled Pine Plantations in Uganda

background

This 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 & Methods

Sampling 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.

Effects of Ground Preparation and Microenvironment on Germination and Natural Regeneration of Juniperus procera and Afrocarpus gracilior in Ethiopia

Background

This 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.

Changes in Plant Species Composition Within a Planted Forest in a Deciduous Agroecosystem in Ghana

Background

Early-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.

Indigenous Trees in West African Forest Plantations: The Need for Domestication by Clonal Techniques

background

This 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.

Regeneration Response of Juniperus procera and Olea europera subsp cuspidata to Exclosure in a Dry Afromontane Forest in Northern Ethiopia

background

This study investigates the natural regeneration of Juniperus procera and Olea europeaea subsp. cuspidata after 3 years under protection from livestock, human interference, and under open management systems in a dry Afromontane forest in northern Ethiopia.

Regeneration of Indigenous Trees in Mgahinga Gorilla National Park, Uganda

background

This 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 & Methods

Indigenous species diversity was assessed by systematic sampling of the vegetation and soils in transect plots.

Impact of Exotic Plantations and Harvesting Methods on the Regeneration of Indigenous Tree Species in Kibale Forest, Uganda

background

In the late 1960s and early 1970s, exotic tree plantations were established in hilltop grassland sites of the Kibale Forest Reserve. In the late 1990s and early 2000s, many of these sites were selected for logging to encourage growth of native trees.

Research Goals & Methods

This study assesses the impact of both pitsawing and sawmilling of exotic species plantations on the colonization and regeneration of indigenous species. Tree enumeration was conducted within plots representing the different plantation types and harvesting methods in order to determine indigenous species richness and diversity.
