Does Forest Restoration using Taungya Foster Tree Species Diversity? The case of Afram Headwaters Forest Reserve in GhanabackgroundThis study evaluates taungya agroforestry system - a forest restoration effectiveness in promoting high tree diversity- in Ghana. This study was conducted in a forest reserve buffered by Teak and Cedrella-taungya on logged, cropped and burned land. Available with subscription or purchase |
Native Tree Species Regeneration and Diversity in the Mountain Cloud Forests of East AfricabackgroundThis study evaluates the diversity of native species regeneration within 3 native and exotic forest plantations of the indigenous forests of Tatia Hills, East Africa. Research Goals & MethodsResearchers monitoried species diversity, richness and similarity of regenerated species between exotic plantations of pine, eucalyptus and cypress, as well as between native and exotic forests.

Impact of Exotic Plantations and Harvesting Methods on the Regeneration of Indigenous Tree Species in Kibale Forest, UgandabackgroundIn the late 1960s and early 1970s, exotic tree plantations were established in hilltop grassland sites of the Kibale Forest Reserve. In the late 1990s and early 2000s, many of these sites were selected for logging to encourage growth of native trees. Research Goals & MethodsThis study assesses the impact of both pitsawing and sawmilling of exotic species plantations on the colonization and regeneration of indigenous species. Tree enumeration was conducted within plots representing the different plantation types and harvesting methods in order to determine indigenous species richness and diversity.

High Seedling Recruitment of indigenous Tree Species in Forest Plantations in Kakamega Forest, Western KenyabackgroundThe study evaluates the potential for seedling recruitment of indigenous tree species in different types of plantations and secondary forest in western Kenya. The plantations are comprised of mixtures and monocultures of single or exotic indigenous tree species. Available with subscription or purchase |
Indigenous Woody Species Diversity in Eucalyptus globulus Labill spp. globulus Plantations in the Ethiopian HighlandsbackgroundThis study evaluates the regeneration of native woody species in eucalyptus plantations in the central highlands of Ethiopia. Research Goals & MethodsUnderstory trees and shrubs were identified and measured in 11 year old plantations at Chancho where no natural forests remain, and in 37 year old plantations at Menagesha where remnant natural forests exist.

Applied Nucleation as a Forest Restoration StrategybackgroundTo combat deforestation and restore forest cover quickly and efficiently, this article proposes the use of applied nucleation as a restoration strategy. The article reviews research to date on applied nucleation, which is a method for restoring degraded landscapes in which small clusters of shrubs and trees are planted to encourage natural forest regeneration.

Rehabilitation of Degraded Tropical Forest LandsbackgroundThis article discusses the options for the rehabilitation of degraded land on high rainfall areas. It suggests that it is both environmentally and economically disadvantageous to let the degraded land remain in an unproductive and rapidly eroding state. Available with subscription or purchase |
Optimising Seedling Management: Pouteria sapota, Diospyros digyna, and Cedrela odorata in a Mexican RainforestbackgroundThis study compares the height growth of three native tree species (Pouteria sapota, Diospyros digyna, and Cedrela odorata) during the first two years after transplantation from a nursery in three plot types (primary rainforest, secondary forest, and open pasture) in Veracruz, Mexico. Research Goals & MethodsThe effects of canopy closure, leaf nutrients, initial seedling height and seed mass on the final height of the plant after two years were analyzed.

Restoration of a Sri-Lankan rainforest: Using Caribbean Pine Pinus caribaea as a nurse for establishing late-successional tree speciesBackgroundIn the moist tropics, studies have demonstrated poor seedling establishment of late-successional trees on lands cleared of forest. This study examines the potential for establishing late-successional tree species that dominate the canopy of rainforest by planting within and adjacent to experimental openings that were created within a Pinus caribaea plantation.
