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. Open access copy available |
Caracterização do Dossel e do Estrato de Regeneração Natural no Sub-Bosque e em Clareiras de Uma Florestal Estacional Semidecidual no Município de Viçosa, MGThe 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. Open access copy available |
Banco de Sementes como Indicador de Restauração de uma Área Degradada por Mineração de Caulim em Brás Pires, MGThe 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). Open access copy available |
Restauración ecológica de bosques tropicales en Costa Rica: efecto de varios modelos en la producción, acumulación y descomposición de hojarasca
EspañolAntecedentesEste estudio se llevó a cabo en Coto Brus, y se enfoca en la restauración de paisajes agrícolas fragmentados dentro del Corredor Biológico Amistosa. El mismo es un área prioritaria para la forestería y la conservación en Costa Rica que ha sido degradrada y transformada por la expansión agrícola durante los pasados 50 años, dejando solo un 25% del bosque original.

Restauração de áreas degradadas: a nucleação como base para incrementar os processos sucessionais (Restoration of degraded areas: nucleation as a base for augmenting successional processes)This article includes a general discussion of the rationale and theory behind nucleation as a way to facilitate forest restoration. The authors explain various nucleation techniques, including soil transfer, direct seeding and hydro-seeding, artificial poles, transfer of branches and organic matter, the planting of seedlings in islands of high diversity, and the collection of seeds for maintenance of genetic variability Este artigo trata-se de uma discussão geral do raciocínio e a teoria da nucleação como uma maneira de facilitar a restauração florestal.
