Analysis of the "Shelter Tree-Effect” of Natural and Exotic Forest Canopies on the Growth of Young Podocarpus falcatus Trees in Southern EthiopiabackgroundThe potential for plantations of fast-growing non-native trees to create suitable habitat for regeneration of native plant ecosystems has gained attention in the scientific literature. Previous studies often focus on the plantation species’ impacts on soil, but this study in the Munessa-Shashemene forest of Ethiopia proposes that light factors may be important as well. In this forest, native Podocarpus falcatus saplings actually perform better under the canopy of planted non-native Pinus patula and Eucalyptus saligna trees than in native forest, and this study hypothesizes that varying patterns of irradiance and sunflecks may explain this phenomenon.

Succession and Regeneration Patterns of East African Mountain Forests: A ReviewbackgroundFor 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 ForestbackgroundThis 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. research goals & methodsVegetation data was collected from 40 sample plots, 20 in natural forest and 20 in plantations. Within the plots plant species were identified, DBH of all trees measured using a caliper; total heights of larger trees were measured using hypsometer. Available with subscription or purchase |

Regeneration of Timber Species following Selective Logging in a Moist Semi-Deciduous Forest in GhanabackgroundThis study examines the types and frequency of natural regeneration and growth of timber tree species in 4 logging gaps: loading bays, tree-fall, primary and secondary skid trails with forest shade as control in a moist semi-deciduous forest in Ghana.

Managing afforestation and reforestation for carbon sequestration: considerations for land managers and policy makersBackgroundThis chapter focuses on managing afforestation & reforestation projects with an eye towards carbon sequestration. While temperate regions contain the majority of the world’s naturally regenerated and planted forests, the most rapid rates of reforestation occur in the tropics.

Rehabilitation of Forest-Savannas in Ghana: The Impacts of Land Use, Shade, and Invasive Species on Tree RecruitmentbackgroundThis 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 EthiopiabackgroundThis 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 & MethodsTo 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 GhanabackgroundThis 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 & MethodsChromolaena 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.
