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).

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.

Impacto humano afeta negativamente a dispersão de sementes de frutos ornitocóricos: uma perspectiva global (Human impact affects negatively the seed dispersal in ornithochorous fruits: a global perspective)

This literature-based analysis used data from a number of existing studies of seed dispersal by birds to compare the effects of plant characteristics and human impact on bird choice and seed dispersal. The study found that plant morphological characteristics did not effect on the frequency of bird visits or fruit consumption. However, the human impact on each site did have a significant effect. Areas with high human pressure had more than 3 times fewer visits and fruit consumed by birds. These data may be important for restoration efforts in gauging the intensity of seed rain for tree species dispersed by birds.

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.

Cobertura De Copas Como Indicador De Desenvolvimento Estrutural De Reflorestamentos De Restauração De Matas Ciliares No Médio Vale Do Paranapanema, SP, Brasil

This study analyzed crown cover in riparian forests 1 to 3 years after reforestation in the Médio Vale do Rio Paranapanema, São Paulo, Brazil to evaluate the technique as a means to monitor the progress of restoration. Using a line inspection technique, crown cover significantly correlated with age, height, basal area, and DBH. The authors concluded that this is a suitable technique for planted riparian forests up to 3 years in age to evaluate changes in forest structure, and suggest that models might be developed to predict crown cover based on age and site variability.
