Economic Analysis of Sengon (Paraserianthes falcataria) Community Forest Plantation, a Fast Growing Species in East Java, Indonesia

background

This article examines Paraserianthes falcataria (Sengon) mixed community forest plantations in East Java, Indonesia. The Indonesian government launched a timber / reforestation program in 1990 but only 20% of projected timber supply has come from these plantations, and total reforested area is far below targets. Before 1997, forest resources were held by concession companies, and local access rights were denied. Under reforms however, government decentralization gave local governments more authority to manage their resources, and extensive deforestation (and low levels of reforestation) has followed.

Timber Investment Returns for Selected Plantations and Native Forests in South America and the Southern United States

background

This 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 Biomass

background

Moringa 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.

Research Goals & Methods

In this study, dehulled seeds had a high germination rate (65%), whereas hulled seeds had low germination.

Effect of Land Prices, Transportation Costs, and Site Productivity on Timber Investment Returns for Pine Plantations in Colombia

background

This study assesses the importance of  land costs, site quality, and forest location on financial returns of forestry investments. 

Goals & Methods

The factors mentioned above were analyzed using data from pine plantations in the Andean region of Colombia.  Researchers determined site quality based on annual growth rates and they calculated  comparative return on forest investment based on sales of wood, market prices, wood transport costs, and bare land costs.

A Strategy for Restoration of Montane Forest in Anthropogenic Fern Thickets in the Dominican Republic

Background

This study looked at the potential of different tree species to grow in clearings in fern-dominated thickets in a state of arrested succession. It was conducted in the Ébano Verde Scientific Reserve in the Dominican Republic with subtropical montane forest.

Research Goals & Methods

The authors cleared fern-dominated shrubs with machetes and planted 18 species of early and late successional trees and shrubs with and without a single application of fertilizer.

Can Intensive Management Accelerate the Restoration of Brazil’s Atlantic Forests?

background

This 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.
