The Potential for Species Conservation in Tropical Secondary ForestsBackgroundThe importance of tropical secondary forests for conserving biodiversity increases with the degradation of old-growth forests, yet little is known about the role that these forests play in promoting biodiversity. Geospatial and temporal factors influence the role of secondary forests in species conservation, and this synthesis of case studies evaluates the significance of these factors on regional and landscape scales.

Secondary Forest Regeneration under Fast-Growing Forest Plantations on Degraded Imperata cylindrica GrasslandsBackgroundThis study compares the regeneration of native tree species under the canopy of tree plantations, riverine areas, and uncultivated grassland areas in the Riam Kiwa plantation area of South Kalimantan, Indonesia. This area has a distinct dry season and deeply weathered, acidic soils, and is considered good for forest plantations. Available with subscription or purchase |
Screening Trial of 14 Tropical Hardwoods with an Emphasis on Species Native to Costa Rica: Fourth Year ResultsBackgroundA lack of silvicultural information on native timber species in the tropics has contributed to the propogation of fast-growing exotic tree species in reforestation efforts. The plantations evaluated at the La Selva Biological Station in Costa Rica were considered marginal lands with low input of forest maintenance, reflecting the conditions of many lands that farmers would use for reforestation.

Habitat Distribution of Dipterocarp Species in the Leyte Cordillera: An Indicator for Species – Site Suitability in Local Reforestation ProgramsBackgroundThis article presents the results of a vegetation study in primary forest areas of the Leyte Cordillera in the Philippines, sampling populations of 18 species of Dipterocarp across topographic habitats and elevation classes. As a young volcanic cordillera, this tropical region is dominated by rugged topography, with slopes as steep as 30 to 60 degrees. Open access copy available |
Dipterocarp Forest Ecosystems: Towards Sustainable ManagementBackgroundThis book describes the difficult problem of sustainably managing the valuable resources of Dipterocarp forests in Southeast Asia. It highlights the social, economic, and forest management challenges associated with Dipterocarp governance and attempts to reconcile the often disparate roles of forest scientists and local community managers.

Les plantations forestières en afrique centrale: des sylvicultures nouvelles pour répondre aux nouveaux besoins des sociétésThe article provide several arguments for investing in tree plantations in central Africa where tropical wet and dry forests have been degraded and exploitation of forest resources is unsustainable. The authors give examples of benefits from native plantations in addition to exotic plantations. The article concludes by discussing the benefits tree plantations can have on society and the need for more scientific research on native tree plantations in central Africa.

Can Pinus Plantations Facilitate Reintroduction of Endangered Cloud Forest Species?backgroundThis study tested the hypothesis that pine plantations can simulate the conditions of early forest succession, acting as a habitat for other native or endangered species to establish. In the cloud forest region of central Mexico, some tree species have become endangered due to land use change for both livestock production and tree plantations. Open access copy available |
Growth in pure and mixed plantations of tree species used in reforesting rural areas of the humid region of Costa Rica, Central AmericaBackgroundDespite government incentives in Costa Rica for establishing and maintaining native tree plantations since the 1990s, farmers and small landowners often lack adequate knowledge about plantation management. Yield and rotation periods for each of the ten most common species grown in monoculture have previously been published. This paper compares productivity in monoculture and mixtures at La Selva Biological Station in the Caribbean lowlands of Costa Rica. Open access copy available |
Foliar herbivory and leaf traits of five native tree species in a young plantation of Central PanamaBackgroundTimber plantations often provide economic incentives for land owners to restore abandoned pastures or agricultural land to forest, yet the threat of insect herbivory can diminish these new plantations and compromise the efforts. This study seeks to understand the extent of these threats on tree plantations in Panama. Open access copy available |
The Role of Silvopastoral Systems in the Rehabilitation of Andean Stream HabitatsbackgroundThis article discusses the prevalence and impact of cattle grazing in the Andean region of Colombia. It asserts that ranching drastically alters the oxygen demand of and pH of streams, increases algae growth, and reduces light penetration. Ranching also damages stream flow and riverbanks, leading to higher erosion and run-off. Grasslands on previously forested areas have led to compaction of soil so that there is less infiltration leading to more run-off, floods due to increased speeds and volume, and less water in the streams during the dry season.
