The Savanna Tree Acacia polyacantha Facilitates the Establishment of Riparian Forests in Serengeti National Park, TanzaniabackgroundThis study tests if stands of Acacia polyacantha facilitate the establishment of forest trees by examining the distribution, growth, and survival of juvenile forest trees. The influence of stand size, locations within the stand, presence of canopy trees, competition from grasses, effects of fires and effects of thorny shrubs on herbivore exclusion and conditions for establishment of A. polyacantha in grasslands were examined in Serengeti National Park of Tanzania.

The Socio-Economic Effects of Ghana's Government Afforestation Project on Beneficiary Farmers in the Dormaa District of the Brong Ahafo region of GhanaBackgroundForests play a central role in Ghana's global economy and local livelihoods, yet degradation and overharvesting continue to be an issue. In response, the Ghana government implemented an afforstation program in 2001 to restock forests and help alleviate poverty. Open access copy available |
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.

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 |
Restoration of Dry Afromontane forest using pioneer shrubs as nurse-plants for Olea europaea ssp. cuspidataBackgroundShrubs are often considered competitive barriers for seedlings planted in reforestation programs, although they can facilitate tree recruitment, especially in ecosystems under high abiotic stress. An alternative reforestation technique using pioneer shrubs as nurse-plants for Olea europaea ssp. cuspidata was tested in exclosures in northern Ethiopia. Open access copy available |
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 |

Ecología experimental y ecofisiología: bases para el uso sostenible de los recursos naturales de las zonas áridas neo-tropicales (Experimental ecology and ecophysiology in dry tropical forests)El autor recoge los resultados más relevantes que han permitido la resolución de algunos problemas de producción vegetal, que pueden ser utilizados como herramientas fundamentales de planificación para la producción en las tierras secas en el noroeste Venezuela. Las condiciones edáficas y climáticas que caracterizan las zonas áridas y semiáridas tropicales las colocan entre los ecosistemas más frágiles del mundo y más susceptibles a la desertificación.

Manejo del fuego y restauración de bosques en la reserva de la biosfera sierra de Manantlán, México (Fire management and and forest restoration)Los autores analizan la incidencia de incendios forestales y los efectos de los regímenes de fuego sobre los bosques de la Reserva de la Biosfera Sierra de Manantlán en el occidente de México, y se presentan las líneas de acción estratégicas del Programa de Manejo del Fuego y Restauración de Bosques de esta área protegida. A pesar de los esfuerzos de supresión de los incendios forestales en México, se observan tendencias de aumento en la superficie quemada y en la severidad de los efectos del fuego.
