Establishment of Broad-leaved Thickets in Serengeti, Tanzania: The Influence of Fire, Browsers, Grass Competition, and Elephants

Background

In Tanzania, thickets are declining due to frequent fires yet when the fires are removed the thickets fail to regrow. As a fire-resistant tree, seedlings of E. divinorum are potentially an ideal species to restore these land covers.

Intensive Tree Planting Facilitates Tropical Forest Biodiversity and Biomass Accumulation in Kibale National Park, Uganda

background

This study investigates how intensive planting affects tropical forest regeneration and biomass accumulation in reforested sites in Kibale National Park, Uganda. The study assessed species richness of naturally regenerating (i.e. non-planted) species in the park and compared the biomass accumulation of planted versus naturally regenerating trees in sites replanted by the Uganda Wildlife Authority.

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.

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.

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.

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.

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.

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.

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.

Fire Control as a Simple Means of Promoting Tropical Forest Restoration

background

This 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.
