Tropical Forest Transitions and Globalization: Neo-Liberalism, Migration, Tourism, and International Conservation Agendas

Background

Deforestation is giving way to forest regeneration in some tropical regions. This paper uses two case studies to investigate such ‘forest transitions’ in two biodiversity-rich countries, Costa Rica and Madagascar.

Regeneration of Indigenous Trees in Mgahinga Gorilla National Park, Uganda

background

This study examines the dominant exotic species, their distribution and effect on the regeneration of indigenous tree species in the formerly encroached area of Mgahinga Gorilla National Park, southwestern Uganda. The 4 habitat types examined were exotic woodlots, old croplands and natural forest habitat.

High Seedling Recruitment of indigenous Tree Species in Forest Plantations in Kakamega Forest, Western Kenya

background

The study evaluates the potential for seedling recruitment of indigenous tree species in different types of plantations and secondary forest in western Kenya. The plantations are comprised of mixtures and monocultures of single or exotic indigenous tree species.

Does Forest Restoration using Taungya Foster Tree Species Diversity? The case of Afram Headwaters Forest Reserve in Ghana

background

This study evaluates taungya agroforestry system - a forest restoration effectiveness in promoting high tree diversity-  in Ghana. This study was conducted in a forest reserve buffered by Teak and Cedrella-taungya on logged, cropped and burned land.

Tree regeneration in church forests of Ethiopia: effects of microsites and management

Background

Tree regeneration is severely hampered in the fragmented afromontane forests of northern Ethiopia. Pressures of harvesting and grazing and climactic conditions present challenges to regeneration. This study explores how trees regenerate in remnant forests along the gradient from open field, forest edge to closed sites and canopy gaps inside the forest.

Changes in Plant Species Composition Within a Planted Forest in a Deciduous Agroecosystem in Ghana

Background

Early-successional tree plantations can promote regeneration of second-growth mixed-species forests. While non-native species have been studied for their role in enabling second-growth regeneration, this study surveys understories of plantations of trees native to Ghana in a post-maize site to explore the suitability of native trees for promoting second-growth regeneration.

Effects of Ground Preparation and Microenvironment on Germination and Natural Regeneration of Juniperus procera and Afrocarpus gracilior in Ethiopia

Background

This study assesses the net effect of seed supply and seedbed changes on germination and natural regeneration of J. procera and A. gracilior in the Afromontane forests of Ethiopia.

Occurrence of Nodulation in Unexplored Leguminous Trees Native to the West African Tropical Rainforest and Inoculation Response of Native Species useful in Reforestation

Background

Few studies examine the ability of leguminous tree species to nodulate and fix atmospheric N, especially symbiotically with rhizobia; this study seeks to fill that research gap.  The occurrence of nodulation was determined in 156 mature leguminous species growing in 6 natural forest areas in south-eastern Guinea and an in situ experiment of rhizobia inoculation was performed on 8 selected tree species.
