Evaluación técnica y financiera de la silvicultura desarrollada en un bosque natural de la Guayana venezolana (Technical and financial evaluation of silvicultural management in the Venezuelan Guayana)Los autores analizan el funcionamiento de una empresa forestal que ejecuta, desde 1996, un plan de ordenación y manejo forestal en un bosque seco tropical, El Dorado- Tumeremo, con una superficie productiva 66 000 ha (Estado Bolívar, Venezuela). Se aprovechan unas 30 especies según diámetros mínimos de corta, clasificadas según su potencial comercial: las comerciales (Hymenaea courbaril, Pouteria caimito, Spondias mombin, Cordia alliodora, Andira sp., Manilkara bidentata y Peltogyne pubescens), las potencialmente comerciales (Cordia bicolor, Fagara martinicense, Tetragastris panamensis, Ceiba pentandra, Brosi- mun alicastrum, Aspidosperma megalocarpum, Astronium lecontei) y las que no tienen valor com Open access copy available |
Hacia una silvicultura sostenible en el trópico seco: el caso de la Finca Piedra Rala, Nicaragua (Towards sustainable silviculture in dry tropical forests: the case of Finca Piedra Rala, Nicaragua)El autor explica la experiencia de los productores en el manejo racional de pequeñas áreas de bosque tropical seco y analiza como la silvicultura racional tiene una capacidad de regeneración de los bosques naturales poco productivos en la zona del Pacífico de Nicaragua. En la finca estudiada, el bosque es sometido a un sistema de aprovechamiento tradicional, desarrollado como una iniciativa del propietario. Open access copy available |

Restoring abandoned pasture land with native tree species in Costa Rica: Effects of exotic grass competition and lightBackgroundUnderstanding the early establishment requirements and performance of tropical tree seedlings is essential to ensuring the success of restoration plantings. This study characterizes growth and light requirements of six common neotropical tree species: Pseudosamanea guachapele (Fabaceae), Tabebuia impetiginosa (Bignoniaceae), Ceiba pentandra (Bombacaceae), Pachira quinata (Bombacaceae), Dalbergia retusa (Fabaceae), and Tabebuia rosea (Bignoniaceae).

The Structure and Composition of a Tropical Dry Forest Landscape After Land Clearance; Azuero Peninsula, PanamabackgroundThis article describes natural regeneration that has occured in five different habitat types in the Azuero Peninsula of Panama. These habitat types include active pasture, 2-yr abandoned pasture, 5-yr abandoned pasture, forest riparian zones, and a secondary forest fragment. This region is characterized by agricultural and cattle ranching landcapes in areas that previously were tropical dry forest (1700 mm rainfall per year) until the mid-20th century and have recently been undergoing rapid turnover in land ownership.

Evaluation of Reforestation Potential of 83 Tree Species Planted on Imperata cylindrica Dominated Grassland – A case Study from South Kalimantan, IndonesiabackgroundIn this study, 83 tree species (native and exotic) were tested for their growth and survival in species selection trials in South Kalimantan, Indonesia. Research Goals & MethodsThe trees were planted between January 1987 and December 1988 in areas dominated by the exotic grass Imperata cylindrica and weeding was conducted twice a year.

Potential of Agroforestry and Plantation Systems in Indonesia for Carbon Stocks: an Economic PerspectivebackgroundThis article discusses the potential for carbon sequestration services in various agroforestry systems in Indonesia. The systems specifically discussed include shade based coffee (Coffea robusta), fruit based coffee, timber based coffee, rambutan (Nephelium lappaceum), pinang (Areca catechu), mango (Mangifera indica), macang (Mangifera spp), candle nut (Aleurites moluccana), durian (Durio zibethinus), duku (Lansium domesticum), and sengon (Paraserianthes falcataria) systems.

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.
