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.

Research Goals & Methods

Landcover analyses were conducted to determine the extent and spatial distribution of temporal forest change and to provide an initial analysis of forest cover change both within and around the park.

Factors Limiting the Survival of Native Tree Seedlings used in Conservation Efforts at the Edges of Forest Fragments in Upland Madagascar

background

This study investigates the survival of tree seedlings 15 months after planting in grasslands along the edges of tropical forest fragments damaged by fire in four restoration treatments in upland Madagascar.

Consequences of plantation harvest during tropical forest restoration in Uganda

Background

Timber plantations have recently received considerable attention as a forest restoration strategy for heavily degraded lands in the humid tropics. Plantations can facilitate secondary forest regrowth by providing an understory environment more favorable for native plant recruitment than unmanaged degraded habitats. This study explores how using plantations as a restoration tool affects forest succession; how initial floristics affect successional pathways; and the effect of fire exclusion or other interventions.

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.

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.

Research Goals & Methods

To sample for vegetation diversity and analyses of floristic composition, species richness, and abundance, 60 sample plots were established in the study area.  48 of these plots were in plantations and 12 were in adjacent natural forests.

Responses of Tree Seedlings to the Removal of Chromolaena odorata Linn. in a Degraded Forest in Ghana

background

This study assesses the effects of Chromolaena odorata, a dense grass removal on native trees seedlings in a degraded dry semi-deciduous forest in Ghana.

Research Goals & Methods

Chromolaena odorata was removed from 50% of the plots and the other half left intact. Seedling height, the number of leaves per seedling, and seedling mortality were investigated in both released and unreleased plots immediately after the release treatment in June 1998 and again 3 months later September 1998.

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.

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.

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.
