Comportamiento de las especies y preferencias de los productores. Plantaciones forestales en Costa Rica y Nicaragua (Species behavior and farmers' preferences. Forest plantations in Costa Rica and Nicaragua)EspañolantecedentesLos autores estudiaron plantaciones comerciales en 112 fincas de productores forestales, en el Cantón de Sarapiquí, Costa Rica y el Departamento de Carazo, Nicaragua. objetivos y metodologíaEl trabajo realiza un inventario de las plantaciones forestales en todas las fincas estudiadas. Las variables evaluadas incluyen: supervivencia, dap, altura total, forma y sanidad de los árboles. Open access copy available |
Ecological restoration success is higher for natural regeneration than for active restoration in tropical forestsbackgroundThis meta-analysis of 133 studies challenges the widely-held notion that active restoration methods are more effective at ecosystem restoration and hold higher conservation value than natural regeneration. Given the vast commitments for ecosystem restoration across the globe, and the high cost, effort, and resources needed for these commitments, this study proposes that increasing use of natural regeneration and assisted natural regeneration is necessary to achieve these commitments.

Accelerating tropical forest restoration through the selective removal of pioneer speciesbackgroundThis study presents initial findings on the impact of thinning on recovery of a selectively logged secondary forest in Sumatra. The study tests the hypothesis that thinning of pioneer species will produce stands with greater proportional basal area of late-successional species, effectively accelerating succession of the stand.

Forest and landscape restoration severely constrained by a lack of attention to the quantity and quality of tree seed: Insights from a global surveybackgroundThis review article focuses on tree seed supply in the context of forest and landscape restoration (FLR). The article asserts that large-scale FLR commitments will require billions of tree seeds and seedlings, and that this supply is extremely inadequate in terms of not only quantity but also genetic diversity and quality. The article reviews 139 FLR projects worldwide and identifies widespread problems in the availability and diversity of tree seed supply. Open access copy available |
Natural regeneration as a tool for large‐scale forest restoration in the tropics: prospects and challengesbackgroundThis article is a review of natural regeneration in the context of large-scale forest restoration in the tropics. The article provides case studies of successful natural regeneration, pointing out the side benefits of genetic adaptation, traditionally-used species, and local biodiversity. These features also bring greater ecosystem resilience. Open access copy available |
Restoration of Degraded Tropical Forest LandscapesBackgroundDeforestation and the declining extent of tropical forests has negatively impacted ecosystem functions, services, and goods and has disproportionately harmed the rural poor of tropical countries. In the wake of deforestation, agricultural development and traditional methods of reforestation (plantations) have largely failed to provide sustainable livelihoods. This review article assesses the strengths and weaknesses of different tropical restoration methods to combat forest degredation and address rural poverty. Open access copy available |
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.

Genetic Consequences of Tropical Second-Growth Forest RegenerationBackgroundThis article is an examination of the genetic impacts of old-growth deforestation among 24 year-old second-growth Iriartea deltoidea, a canopy palm, in a lowland Costa Rican forest. Iriartea is widely distributed throughout neotropical rainforests and displays a diverse range of size classes in mature forests. This species recolonizes second-growth forests with newly generated seeds, which are dispersed by birds and mammals. Open access copy available |
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.
