Tropical rainforest regeneration in an area degraded by mining in Mato Grosso State, BrazilBackgroundGold mining has been a major cause of environmental degradation in the rainforests in the north of Mato Grosso State, Brazil. Regulations on mining activity are beginning to be developed, including standards for forest recovery methodologies. This study characterizes natural tropical rainforest regeneration in Matupa County, Mato Grosso State, Brazil. 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 |

Restoration of dry tropical forests in Central America: A review of pattern and processBackgroundMuch information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest, of which less than 2% remains intact.

Isolated Trees and Grass Removal Improve Performance of Transplanted Trema micrantha (L.) Blume (Ulmaceae) Saplings in Tropical PasturesbackgroundThis research evaluates the survival and growth of saplings of Trema micrantha when transplanted into recently abandoned pastureland in southeast Mexico. Trema micrantha is a pioneer species native to Mexico with ecological and physiological properties that would make it viable for planting in open fields. Research Goals & MethodsSaplings were planted in 2004 and evaluated every three months for the following year. Available with subscription or purchase |
Factors Affecting Community Composition of Forest Regeneration in Deforested, Abandoned Land in PanamabackgroundThis study tests how Saccharum spontaneum, an invasive grass, affects early forest succession and community composition in an area of previously abandoned pasture.

Seed rain and seed limitation in a planted gallery forest in BrazilBackgroundSeed dispersal by wind (anemochorous) and animals, usually birds and bats (zoochorous), is an important driver of succession. This study examines seed rain in a planted gallery forest (riparian corridor) in Brazil. Available with subscription or purchase |
Responses of 20 Native Tree Species to Reforestation Strategies for Abandoned Farmland in PanamaBackgroundIn the tropics, deforestation often leads to unproductive agriculture and results in degraded grasslands. This study seeks to understand why forests fail to regenerate naturally in these ecosystems. Open access copy available |
