High Seedling Recruitment of indigenous Tree Species in Forest Plantations in Kakamega Forest, Western Kenya

background

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.

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.

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.

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.

Tree regeneration in church forests of Ethiopia: effects of microsites and management

Background

Tree regeneration is severely hampered in the fragmented afromontane forests of northern Ethiopia. Pressures of harvesting and grazing and climactic conditions present challenges to regeneration. This study explores how trees regenerate in remnant forests along the gradient from open field, forest edge to closed sites and canopy gaps inside the forest.

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.

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.

Rehabilitation of Forest-Savannas in Ghana: The Impacts of Land Use, Shade, and Invasive Species on Tree Recruitment

background

This study investigates the varying potential of soil seed banks of predominant agricultural land uses for the recruitment of trees from seeds and seedlings in 3 farming communities in a forest-savanna ecological zone in Ghana.

Native Woody Species Regeneration in Exotic Tree Plantations at Munessa-Shashemene Forest, Southern Ethiopia

background

This study investigates native woody species regeneration in 4 exotic species monoculture plantations in Munessa-Shashemene Forest Project Area in southern Ethiopia. The plantation ages ranged from 9 to 28 years.

Succession and Regeneration Patterns of East African Mountain Forests: A Review

background

For decades East Africa has experienced heavy tree felling, which has resulted in a change in species composition. This study conducted the phytosociological in Kenya and Ethiopia between 1992 and 1996 in order to understand the succession and regeneration processes in East African Mountain forests.

A Comparative Assessment on Regeneration Status of Indigenous Woody Plants in Eucalyptus grandis Plantation and Adjacent Natural Forest

background

This study investigates and compares diversity, density and species composition of naturally regenerated woody plants under Eucalyptus grandis plantations and the adjacent natural forest in southwestern Ethiopia.

Understory Vegetation in Fast-Growing Tree Plantations on Savanna Soils in Congo

background

The study investigates the hypothesis that tree plantations established adjacent to natural forests may catalyze the regeneration of natural forest biodiversity in the Congo.

Parks as a Mechanism to Maintain and Facilitate Recovery of Forest Cover: Examining Reforestation, Forest Maintenance and Productivity in Uganda

background

This study highlights the use of parks as a tool for restoration and forest maintenance with a focus on Kibale National Park in Uganda.  The authors assess methodological approaches and limitations with current techniques to study land cover change.

Survival and Growth of Seedlings of 19 Native Tree and Shrub Species Planted in Degraded Forest as Part of a Forest Restoration Project in Madagascar's Highlands

background

This study compares the survival rates of 19 native tree and shrub species grown in a forest restoration project in Madagascar’s highlands. The study results are used to compare the survival of relatively short seedlings compared to relatively tall seedlings for all species combined in order to test the importance of seedling size for restoration.
