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 |
Canal blocking strategies for hydrological restoration of degraded tropical peatlands in Central Kalimantan, IndonesiaBackgroundIn the 1990s, the Government of Indonesia sponsored the construction of thousands of km of canals in 1 million Ha of peatlands of Central Kalimantan to drain the peatlands for conversion to agriculture. The project over-drained the peatlands, leaving it unusable agriculturally and subject to fires and subsidence. Existing efforts to dam the canals to return the water table to previous levels have failed. Open access copy available |
Connecting sustainable agriculture and wildlife conservation: Does shade coffee provide habitat for mammals?BackgroundShade coffee systems are believed to support diverse wildlife. However, most research on wildlife in shade coffee has focused on bird and insect diversity, with few studies that have focused on mammals living within coffee-dominated landscapes.

Can tropical farmers reconcile subsistence needs with forest conservation?backgroundDespite efforts to protect tropical rainforests through various policy initiatives, forests continue to face pressure from smallholders' subsistence needs, especially in montane regions. This paper proposes a means to turn abandoned montane pastoral land into productive agroforestry land as a viable alternative to further encroachment on existing forests.
