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.

Restoration and Rehabilitation of Degraded Ecosystems in Arid and Semi-Arid Lands. II. Case studies in Southern Tunisia, Central Chile and Northern CameroonbackgroundThis study compares non-human and human determinants of ecosystem degradation processes in three contrasted regions, as well as interventions tested in each. The three responses to ecosystem degradation under review are restoration, rehabilitation and reallocation as applied to ongoing projects in arid mediterranean region of southern Tunisia, the semi arid tropical savannas of northern Cameroon.

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 |
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 |
Experiences of a research institute in forest restoration practices in NigeriaBackgroundThis paper reports on the activities championed by the Forestry Research Institute of Nigeria within its mandates particularly in the area of forest conservation and management in six ecological zones of the country to recuperate the nations’ ecological integrity.

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 |
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 |
