Comportamiento de las especies y preferencias de los productores. Plantaciones forestales en Costa Rica y Nicaragua (Species behavior and farmers' preferences. Forest plantations in Costa Rica and Nicaragua)EspañolantecedentesLos autores estudiaron plantaciones comerciales en 112 fincas de productores forestales, en el Cantón de Sarapiquí, Costa Rica y el Departamento de Carazo, Nicaragua. objetivos y metodologíaEl trabajo realiza un inventario de las plantaciones forestales en todas las fincas estudiadas. Las variables evaluadas incluyen: supervivencia, dap, altura total, forma y sanidad de los árboles. Open access copy available |
Crecimiento Comparativo de Especies Nativas y Teca plantadas en parcelas puras y mixEspañolantecedentesEl interés por la reforestación como una alternativa a la deforestación se ha incrementado en los últimos años en Panamá. Sin embargo, en las iniciativas de reforestación las exigencias de las plantas no son usualmente consideradas y las mas utilizadas son especies introducidas. Open access copy available |
Screening Trial of 14 Tropical Hardwoods with an Emphasis on Species Native to Costa Rica: Fourth Year ResultsBackgroundA lack of silvicultural information on native timber species in the tropics has contributed to the propogation of fast-growing exotic tree species in reforestation efforts. The plantations evaluated at the La Selva Biological Station in Costa Rica were considered marginal lands with low input of forest maintenance, reflecting the conditions of many lands that farmers would use for reforestation.

Habitat Distribution of Dipterocarp Species in the Leyte Cordillera: An Indicator for Species – Site Suitability in Local Reforestation ProgramsBackgroundThis article presents the results of a vegetation study in primary forest areas of the Leyte Cordillera in the Philippines, sampling populations of 18 species of Dipterocarp across topographic habitats and elevation classes. As a young volcanic cordillera, this tropical region is dominated by rugged topography, with slopes as steep as 30 to 60 degrees. Open access copy available |
Evaluation of Natural Regeneration and Tree species diversity in Miombo woodlands in MalawibackgroundThis study seeks to determine the best management practices for the miombo woodland in Chongoni Forest Reserve, Malawi. Research Goals & MethodsThe authors used plots with four silvicultural practices-complete coppice, coppice with standard, selective thinning, and a control plot-to determine which method would have the best outcome for tree species diversity and natural regeneration of trees.

Quarry dust emission effects on tree species diversity in Chongoni forest Reserve and vegetation characteristics in adjacent villages, Dedza, MalawiBackgroundQuarry dust is widely reported to have adverse effects on both human health and plant community structure, particularly resulting in decreased diversity and ecosystem functions. Therefore, it is critical to examine and monitor the interactions between these dust particles and vegetation. Open access copy available |
Ecological Study of Kirisia Forest ReserveBackgroundIn order to inform a 2009 Conservation Enterprise Development Program, a preliminary ecological survey was carried out at the Kirisia Forest Reserve in Samburu District, Kenya. The survey was in response to an aerial survey conducted by the Wilderness Foundation UK that examined potential drivers of forest destruction. Open access copy available |
Non-timber Forest Product Harvest does not Affect the Genetic Diversity of a Tropical Tree Despite Negative Effects on Population FitnessbackgroundThe authors investigated a relationship between exploitation of economically important mahogany in Benin and the species genetic diversity. The study is base on the theory that disturbances in forest habitats can lead to a decrease in diversity due to population fragmentation and increased inbreeding. Open access copy available |
