Analysis of the "Shelter Tree-Effect” of Natural and Exotic Forest Canopies on the Growth of Young Podocarpus falcatus Trees in Southern Ethiopia

background

The 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 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.

research goals & methods

Vegetation 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.

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.

Effect of Taungya on Regeneration of Endemic Forest Tree Species in Nigeria: Edo State Nigeria as a Case Study

background

This study aims to investigate the number of native species that can regenerate under natural conditions in a 3-year Taungya system in Edo State, Nigeria. Taungya is an agroforestry system that combines forestry practices with agriculture and agriculture-related activities.

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.

Regeneration of Timber Species following Selective Logging in a Moist Semi-Deciduous Forest in Ghana

background

This 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.

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.

Floristic Composition, Structure and Natural Regeneration in a Moist Semi-Deciduous Forest following Anthropogenic Disturbances and Plant Invasion

background

This 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.
