Involving Local Farmers in Rehabilitation of Degraded Tropical Forests: Some Lessons from GhanabackgroundThis 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. Available with subscription or purchase |
Effect of Nursery Practices on Seedling Survival and Growth of Selected Miombo Tree Species, Morogoro, TanzaniabackgroundThis 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 & MethodsFor 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 KenyabackgroundThis 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). Available with subscription or purchase |
Trade-offs between tree cover, carbon storage and floristic biodiversity in reforesting landscapesBackgroundThe 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 ElephantsBackgroundIn 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. Available with subscription or purchase |
Intensive Tree Planting Facilitates Tropical Forest Biodiversity and Biomass Accumulation in Kibale National Park, UgandabackgroundThis 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.

Effects of Canopy Cover and Understory Environment of Tree Plantations on Richness, Density and Size of Colonizing Woody Species in Southern EthiopiabackgroundThis study investigates the effects of canopy characteristics and associated understory environmental factors of tree plantations on native woody species colonization in two broadleaved and two coniferous plantations in southern Ethiopia. The plantation forests investigated are surrounded by dry Afromontane natural forest. Available with subscription or purchase |
Restoration and Rehabilitation of Arid and Semiarid Mediterranean Ecosystems in North Africa and West Asia: A ReviewbackgroundThis study systematically analyzes extensive literature on exclosures, afforestation, reafforestation, rehabilitation and other regeneration operations over several million hectares. It also includes 50 years of the author’s personal field experience in 17 of the 20 Mediterranean bioclimatic areas from the Atlantic Ocean to the Aral Sea. 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.

Succession and Regeneration Patterns of East African Mountain Forests: A ReviewbackgroundFor 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.
