Restauración ecológica de bosques tropicales en Costa Rica: efecto de varios modelos en la producción, acumulación y descomposición de hojarasca
EspañolAntecedentesEste estudio se llevó a cabo en Coto Brus, y se enfoca en la restauración de paisajes agrícolas fragmentados dentro del Corredor Biológico Amistosa. El mismo es un área prioritaria para la forestería y la conservación en Costa Rica que ha sido degradrada y transformada por la expansión agrícola durante los pasados 50 años, dejando solo un 25% del bosque original.

Addressing Forest Degradation and Timber Deficits in GhanabackgroundThis report combines the efforts of several studies to present suggestions for best practices in Ghanaian tree plantation systems in the context of the country’s 1996 Forest Development Master Plan, which aimed to reforest 10,000 hectares per year for 20 years. Both public and private plantation systems are discussed, including the country’s Modified Taungya System (MTS)which encourages small-scale plantations. The report presents information on planting schemes, policies, stakeholders, and worker income. Open access copy available |
Restoration of Tropical Forest EcosystemsBACKGROUNDThis book presents a compilation of papers presented at a symposium on "Restoration of Tropical Forest Ecosystems" that occurred in Bonn, Germany during October of 1991. The event, sponsored by Mitsubishi Corporation, addressed the reasons for tropical forest destruction, opportunities and challenges for restoration, rehabilitation and management. This book presents perspectives of authors from different countries and contexts on forestry, ecology, and nature conservation to address the need for restoration and rehabilitation of tropical forests.

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 |
The Role of Rustic Coffee Plantations in the Conservation of Wild Tree Diversity in the Chinantec Region of MexicobackgroundThis study examines the potential of shade coffee systems to promote native tree diversity across the landscape of southern Mexico. Research Goals & MethodsTwenty-two coffee plantations, representing a range of elevation and age of development, were sampled to assess their species compositions. In total, 45 species (34 tree species) were recorded in the plantations, and 77% of them were native species. Open access copy available |
Impacts of Native Trees on Tropical Soils: A Study in the Atlantic Lowlands of Costa RicabackgroundThis article describes the results of a study in Costa Rica that compared the soil fertility in a 2.5 year-old plantation of 6 native tree species, grass pasture, and 20 year-old secondary forest. Research Goals & MethodsSoil extractable Ca, Mg, K, P, Fe, Mn, Cu and Zn, the pH, exchangeable acidity, organic matter and total N were measured in three plots.

Strategies for the Recovery of Degraded Ecosystems: Experiences from Latin AmericabackgroundThis paper reviews the rehabilitation potential of native species forest plantations in lowland Costa Rica, the Atlantic Forest of Bahia, Brazil, and sub-tropical Argentina. Native species can improve forest regeneration where soils are degraded and where sources of propagules are limited. While most tropical plantations are dominated by exotic species, native trees may be more appropriate because they are better adapted to the local environment, are already familiar to local farmers, and their propagules are locally available.

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.
