Understory Regeneration
Fire Control as a Simple Means of Promoting Tropical Forest RestorationbackgroundThis study investigates whether or not fire exclusion allows grasslands to regenerate to forest in a timeframe suitable for reforestation efforts. The researchers compare tree species richness, dbh, diameter at ground height (DGH), and total woody biomass accumulation in 2 plots that have been protected from fire. They measure the size and amount of above ground biomass in plots that have been protected from fire for 12 and 32 years respectively in Kibale National Park, Uganda. Open access copy available |
Floristic Composition, Structure and Natural Regeneration in a Moist Semi-Deciduous Forest following Anthropogenic Disturbances and Plant InvasionbackgroundThis study examines the floristic composition, structure and natural regeneration in three forest types: disturbed forest (DF), undisturbed forest (UF), and disturbed-invaded forest (DIF) in Tinte Bepo forest reserve in Ghana. In addition, this study also considers how anthropogenic disturbances and plant invasion affect plant species composition. Open access copy available |
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 |

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.

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.

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 HighlandsbackgroundThis 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 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.

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.

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.
