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.

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.

Mycorrhizal Interactions for Reforestation: Constraints to Dryland Agroforest in Brazil

background

The authors conducted a review of literature on mycohorrizae in tropical dry forest systems. Their objective was to understand the role that reforestation and mycohorrizae play in providing ecosystem services such as carbon sequestration and flood control.

Research Goals & Methods

Few studies describe the role of mycohorrizae in tropical dry forest; this study seeks to fill that gap.

Florestas e Bioenergia (Forests and Bioenergy)

This article is an overview of the present status and prospects for the use of planted forests for bioenergy in São Paulo state, Brazil. The author compiled data to estimate the state's land area suitable for forest biomass production. Sugarcane and eucalyptus plantations were compared in terms of energy production and costs, with eucalyptus being slightly more than half as expensive / unit energy / hectare as sugarcane. Finally, a series of policy recommendations necessary to facilitate the use of forests for energy production.

Caracterização do Dossel e do Estrato de Regeneração Natural no Sub-Bosque e em Clareiras de Uma Florestal Estacional Semidecidual no Município de Viçosa, MG

The authors analyzed clearings in a forest reserve belonging to the Federal University of Viçosa, MG, to compare the species and composition of clearing and forest understory vegetation. The found that the level of diversity (Shannon index) and species found (n= 69) were similar in the clearings and the understory in the surrounding forest. Coffee (Coffea arabica) and Picramnia regnellii were the most common species in both the clearings and the understory. The authors suggest that the dominance of coffee may be problematic for the regeneration of native species.

Banco de Sementes como Indicador de Restauração de uma Área Degradada por Mineração de Caulim em Brás Pires, MG

The authors germinated the seed bank from degraded former kaolin mining sites that have regenerated naturally for a period of 20 years. They used two light treatments usedfor the germination: one with 11.5% shade, and another with 60%. There was a wide range of variation among the species according to the light level, with some species producing far more seedlings under one treatment that the other. Most (2/3) of the species germinating (total n: 36) were herbaceous, with eight tree species (see above).
