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.

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.

Satellite Data-Based Phenological Evaluation of the Nationwide Reforestation of South KoreaBackgroundSouth Korea's reforestation efforts since the 1950s have been evaluated for changes in biomass, area, and growing stock, but little has been done to study the phenology changes (seasonal changes) and photosynthetic activity, which will help in the preparation of new forest management in light of climate change.

Carbon stocks in biomass and soils of woody species fodder banks in the dry tropics of MexicobackgroundFodder banks are a common feature of tropical silvopasture. This study evaluates the C concentration and storage in above- and belowground tree biomass and soils of fodder banks of Leucaena leucocephala, Guazuma ulmifolia, and a combination of the both species.

The Effect of Deforestation on Water Quality: A Case Study in Cienda Micro Watershed, Leyte, PhilippinesbackgrouNdForests and water are important resources that provide both socioeconomic and ecological benefits. They also are connected, meaning that deforestation has a negative impact on the quality of water flowing through a watershed. This paper seeks to present the detailed effects and relationship between deforestation and water quality. Open access copy available |
Globalization and Forest Resurgence: Changes in Forest Cover in El SalvadorBackgroundThe authors study certain globalization impacts in land-use change in El Salvador. The legacy of war, remittances and international migration are among other factors that have allowed tree resurgence even in highly urban populated areas. This study tracks the different trajectories of forest recovery by analysing remote-sensing satellite images from 1970's to the early 2000's. Open access copy available |
Changing gears during succession: shifting functional strategies in young tropical secondary forestsBackgroundAdaptations toresource availability strongly shape patterns of community composition along successional gradients in environmental conditions. This study examines the extent to which variation in functional composition explains shifts in trait-based functional strategies in young tropical secondary forests during the most dynamic stage of succession (0–20 years).

Bird Perches Increase Forest Seeds on Puerto Rican LandslidesBackgroundForest regeneration is typically difficult after landslides due to loss of above- and below-ground vegetative structure, the soil seed bank, soil nutrients, and soil structure. Landslides are a common occurrence in Puerto Rico due to its steep topography and heavy rainfall periods and often transform into grass- or fern-dominated terrain. Insufficient seed rain is thought to be one contributing factor. Open access copy available |
