Reforesting the Sahel: Farmer Managed Natural RegenerationBackgroundThis study describes the development of a simple income generating and self-promoting reforestation system called Farmer Managed Natural Regeneration (FMNR) developed in Maradi, Niger. FMNR is an agroforestry system based on the natural regeneration and management of tree systems from underground stumps. Open access copy available |

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 |
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.

Enrichment Planting Does Not Improve Tree Restoration when Compared with Natural Regeneration in a Former Pine Plantation in Kibale National Park, UgandabackgroundThis 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. Available with subscription or purchase |
18 Secondary Forests in West Africa: A Challenge and Opportunity for ManagementbackgroundThis chapter discusses the importance and threats to secondary forests in West Africa, and the description of the floristic diversity and forest succession in secondary forest ecosystems. In addition, silvicultural and complementary management systems and the opportunities and challenges related are also discussed. Open access copy available |
Forest Succession in Kibale National Park, Uganda: Implications for Forest Restoration and ManagementbackgroundThis 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. Available with subscription or purchase |
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 |
The Restoration of Degraded Forests in Ghana: A Case Study in the Offinso Forest DistrictbackgroundThis study investigates how density and diversity of key native tree saplings differ in different plantation stand types in plantations adjacent to a degraded forest reserve in the Ashanti Region of Ghana. The influence of overstory species composition on natural regeneration of single exotic (Cedrella odorata and Tectona grandis) and mixed stands (Khaya grandifoliola, Antiaris toxicaria, Ceiba pentandra, Triplochiton scleroxylon, Terminalia superb, Terminalia ivorensis and Anopyxis klaineana) of native species was assessed.
