Can Intensive Management Accelerate the Restoration of Brazil’s Atlantic Forests?backgroundThis study takes place in the heavily degraded Atlantic Forest region of eastern Brazil, where only 7% of the original forest cover remains. The study tests the question of whether intensive management methods similar to those used to establish fast-growing Eucalyptus plantations could also be applied to restoration of rainforest on former pasture-land dominated by grasses.

The Value of Rehabilitating Logged Rainforest for BirdsBackgroundThis study examines a lowland, dry dipterocarp forest in Sabah, Malaysia that had been selectively logged in 1988-89. One area was rehabilitated (enrichment planting and liberation cutting of vines, bamboos, and noncommercial species). This area was surrounded by a naturally reforesting area. The authors suggest that rehabilitation of selectively logged forests is a more effective carbon sink than plantations. Available with subscription or purchase |
Vegetation recovery on earthquake-triggered landslide sites in the Ecuadorian AndesBackgroundIn this study, researchers surveyed vegetation in a landslide on the Quijos river in Ecuador and inventoried species distribution at distances along the landslide. Available with subscription or purchase |
Identifying Fast-Growing Native Trees from the Neotropics using Data from a Large, Permanent Census PlotbackgroundThis paper results from data collected over a decade from 160 trees in a 50 ha plot in BCI Panama. Research Goals & MethodsGrowth in dbh was calculated and a projection (trajectory) was estimated for the life of the tree (using regression). Available with subscription or purchase |
Effect of Land Prices, Transportation Costs, and Site Productivity on Timber Investment Returns for Pine Plantations in ColombiabackgroundThis study assesses the importance of land costs, site quality, and forest location on financial returns of forestry investments.

Timber Investment Returns for Selected Plantations and Native Forests in South America and the Southern United StatesbackgroundThis study examines the value of timber investments in South America. Exotic Eucalyptus in the southern cone (Argentina + Chile) are the most profitable, with Internal Rate of Return of 13-23%, followed by exotic loblolly pine (Pinus taeda), whereas investments in the southeast USA is less profitable.

Development of Soilless Culture Methods for Production of Moringa (Moringa oleifera Lam.) Root and Leaf BiomassbackgroundMoringa is a valuable tropical agroforestry species with a fruit rich in nutrients. This study tested soilless (hydroponic) Moringa cultivation methods given that past research on tissue culture (vegetative reproduction) has shown difficulty in transfer to soil.

Tropical Reforestation in the Asia-Pacific RegionbackgroundThis chapter reviews the meaning and implementation of landscape scale restoration in the Asia-Pacific region. The authors define landscape as a spatial mosaic with differing land use patterns across a gradient, usually involving natural and human-intervened areas which changes through time.

Effects of forest clearing and succession on the carbon and nitrogen content of soils in Puerto Rico and US Virgin IslandsBackgroundConversion of tropical forest lands to agriculture or pasture affects soil organic matter, moisture, and nutrients. This study examines the effects on soil carbon, nitrogen, and moisture at depths up to 100 cm of conversion from forest to agriculture and pasture. Available with subscription or purchase |
Nitrogen Dynamics of Actinorhizal Casuarina Forest Stands and its Comparison with Alnus and Leucaena ForestsBackgroundNitrogen plays a key role in soil fertility and plant productivity. Therefore, in regions in which deforestation has increasingly led to savannization and desertification, afforestation by fast-growing, n-fixing tree species is preferable. This study examines the characteristics of nitrogen fixing trees. Available with subscription or purchase |
