The Role of Seed Banks in Vegetation Dynamics and Restoration of Dry Tropical EcosystemsBackgroundThis paper reviews studies on seed banks in tropical dry forests, comparing them with wet tropical and subtropical vegetation. Research Goals & MethodsSeed banks in dry tropical forests tend to be low and they are density dependant on moisture levels of the area in question. Subtropical seed banks had similar values to dry tropical forests. Majority of the seeds are from pioneer forests. Available with subscription or purchase |
Efecto de la zona de vida y la altitud en la mortalidad y adaptabilidad al primer año de especies forestales en la Cordillera Volcánica Central de Costa RicaEspañolAntecedentesEl entendimiento comprensivo de la restauración de bosques requiere de la comprensión del fenómeno de la mortalidad incluyendo su magnitud y ubicación espacial. En Costa Rica, no existe suficiente información capturando los efectos de climas pluviales sobre la mortalidad de especies forestales, especialmente en zonas altas. Open access copy available |

Reforestation of Bauxite Mine Spoils with Eucalyptus tereticornis Sm. Seedlings Inoculated with Arbuscular Mycorrhizal FungibackgroundIn the Yercaud hills of the Salem Distict, Tamil Nadu, India, the authors investigated the feasibility of using trees inoculated with beneficial mycorrhizae as an alternative to the traditional and more expensive method of spreading topsoil before planting Open access copy available |
Semeando Sustentabilidade em Apuí (Seedling Sustainability in Apuí)The project aims to strengthen environmental management in Apuí, and to increase capacity for the development of more sustainable productive activities. To achieve this goal the project works simultaneously on reinforcing the network of seeds and seedling production, strengthening institutions, supporting planting and forest conservation, building capacity of landholders in rural properties, and providing environmental education and assistance for the creation of a development plan for the municipality. By means of the rotational management of pastures, the project predicts that it will be possible to identify the best alternative to increase production and profitability while simultaneously halting the advancement of deforestation.

Germinación de semillas de seis especies de Bursera del centro de MéxicoEste artículo evaluó la influencia de la temperatura y el almacenamiento en la germinación de seis especies de Bursera nativas a México (B. bicolor, B. bipinnata, B. cipallifera, B. fagaroides, B. glabrifolia, B. grandifolia). Encontraron alta proporciones de semillas vanas en tres especies. Había un aumento en la germinación dentro de condiciones con una temperatura fluctuante (32-18 °C) en comparación con las semillas expuestos a una temperatura constante (25 °C). No hubo diferencias significativas en la germinación entre las especies con semillas almacenadas durante seis meses a temperatura ambiente y en refrigeración (25 °C). Después de cuatro meses, la germinación de Bursera glabrifolia, B. copallifera y B. bicolor fue del 30 a 60%. Open access copy available |
Feasibility of Farmer-Managed Vegetative Propagation Nurseries in CameroonbackgroundThis article reviews farmer-managed vegetative propagation nurseries in Cameroon. The authors summarize the division of costs required to establish and operate the nurseries. Research Goals & MethodsCuttings of Dacryodes edulis, Irvingia gabonensis and Ricinodendron heudelotti were studied. All had successful rates of propagation by cutting, but only Dacryodes edulis had success with air layering. Open access copy available |
Participatory Domestication of Agroforestry Trees: An Example from the Peruvian AmazonbackgroundThis paper describes a program through the International Centre for Research in Agroforestry (ICRAF) to work with farming communities to domesticate native tree species for use in agroforestry and the conservation of tree diversity in their forests.

Putting Participatory Domestication into Practice in West and Central AfricabackgroudThis article reviews the process of participatory community tree domestication in central Africa. Research Goals & MethodsIn case studies examined, nurseries were planned in coordination between the International Center for Agroforestry Research and local communities, and the two groups divided the funding and supply of nursery materials. No salaries were paid to the farmers working in the nursery. ICRAF staff trained community members in propagation techniques. Open access copy available |
