Understory Regeneration
Diversity of Naturally-Regenerated Native Woody Species in Forest Plantations in the Ethiopian HighlandsbackgroundThis 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 & MethodsUnderstory woody species richness, abundance and herbaceous ground cover were recorded in plantations of Pinus patula, Cupressus lusitanica, Grevillea robusta and Juniperus procera.

Farmer Managed Natural Regeneration: The Niger ExperienceBACKGROUNDThis paper reviews the farmer managed natural regeneration (FMNR) program introduced in the Maradi region of Niger around 1983 to restore degraded parts of the lands. FMNR was started in response to past failures of restoration projects that were modeled for temperate climates and in societies and cultures different from those in West Africa. This prompted the use of more conventional traditional methods of regeneration from re-sprouts of felled trees without running expensive nurseries. Open access copy available |
Effect of Exotic Tree Plantations and Site Management on Plant DiversityBackgroundIn this study of species richness, species behavior and stand parameters were analyzed under fast growing exotic tree plantations and compared with the characteristics of nearby secondary forest patches in Pointe-Noire and Loudima in Congo. The plantations were established in a grass-dominated vegetation of native savanna. The planted species investigated were mainly eucalypts hybrid (PF1), and secondarily Acacia auriculiformis and Pinus caribaea. Open access copy available |
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 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.

A 10-year evaluation of the functional basis for regeneration habitat preference of trees in an African evergreen forestBackgroundThis study reports on the growth and survival of experimentally planted tree seedlings in the understory over a 10-year period in a moist evergreen forest at Kibale National Park in Western Uganda.

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 |
Expediting Reforestation in Tropical Forests Grasslands: Distance and Isolation from Seed Sources in PlantationsbackgroundThis study investigates the potential use of tree plantations to facilitate regeneration of indigenous trees in successionally arrested grassland. It focuses on how characteristics of the plantations and native species can determine the type of regeneration occurring in Kibale National Park, Uganda. Open access copy available |
