Diversity of Naturally-Regenerated Native Woody Species in Forest Plantations in the Ethiopian Highlands

background

This paper examines woody species diversity and understory vegetation of naturally regenerated native tree and shrub species in 4-plantation forests and adjacent natural forests in Wono Genet in Ethiopia.

Research Goals & Methods

Understory woody species richness, abundance and herbaceous ground cover were recorded in plantations of Pinus patula, Cupressus lusitanica, Grevillea robusta and Juniperus procera.

Forest Succession in Kibale National Park, Uganda: Implications for Forest Restoration and Management

background

This sudy examines forest succession in 4 plots in former grasslands adjacent to mature forests in Kibale National Park, Ngogo, Uganda. These plots were located in areas protected from fire for .58,25,9 and 30 years for plots 1,2, 3, and 4 respectively.

Enrichment Planting Does Not Improve Tree Restoration when Compared with Natural Regeneration in a Former Pine Plantation in Kibale National Park, Uganda

background

This study assesses the rate of biomass accumulation of planted seedlings relative to natural regeneration in a harvested plantation in Kibale National Park, Uganda. Enrichment planting was carried out in an area where a pine plantation had been harvested to determine the relative value of these management options.

Involving Local Farmers in Rehabilitation of Degraded Tropical Forests: Some Lessons from Ghana

background

This study is an analysis of  a community-based tree planting project in Ghana using the taungya systems with indigenous trees. The project was sponsored by the Forestry Research Institute of Ghana (FORIG), the government of Ghana, and the International Tropical Timber Organization (ITTO). The goal of the tree planting in the project was to improve forest rehabilitation as well as local livelihoods.

Effect of Nursery Practices on Seedling Survival and Growth of Selected Miombo Tree Species, Morogoro, Tanzania

background

This study investigates the effects of shade, polythene tube diameter and height, and soil mixtures on seedling survival and growth of five Miombo tree species in Morogoro, Tanzania.

Research Goals & Methods

For each species, two nursery experiments were carried out. That is a) degree of shading, pot diameter and height trial, which adopted a split-split plot design with three replications and b) nursery soil mixtures adopted a completely randomized block design with three replications.

Recovery of Plant Species Richness and Composition in Abandoned Forest Settlement Area in Kenya

background

This paper examines natural regeneration of tree species in a former forest village settlement that had been cultivated and abandoned in Mau forest, Kenya. Following 19 years of abandonment, the site consists of 3 zones of recovery due to different degrees of degradation before abandonment, continued grazing, selective logging and firewood collection. The zones are grass zone (GZ), transition zone I (TZ I) and TZ II and secondary forests (SF).

Trade-offs between tree cover, carbon storage and floristic biodiversity in reforesting landscapes

Background

The multiple benefits of reforestation projects for carbon sequestration, biodiversity, and other ecosystem services are taken as a given. Yet not all forests are equal. Plantation-type reforestation projects typically undertaken for carbon sequestration are known for low species richness and inadequate provision of other ecosystem services. This study explores the relationships between an increase in tree cover area and changes in forest carbon storage and the potential of a landscape to provide habitat for native floristic biodiversity.

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.
