Domesticación y fitoquímica de Quassia amara (Simaroubaceae) en el trópico húmedo de Costa Rica (Domestication of Quassia amara in Costa Rica)En el Jardín Agroecológico Bougainvillea, ubicado en la zona atlántica de Costa Rica, se desarrolla un proceso de domesticación de Quassia amara L., con la finalidad de contribuir a la disminución de la recolección de poblaciones de plantas naturales del bosque y de promover una mayor conservación del ambiente, mediante prácticas de cultivo apropiadas, basadas en un modelo agroecológico. Los autores describen algunas características de Quassia amara, tales como taxonomía, distribución, usos, farmacognosia y algunas actividades biológicas. Open access copy available |

Parks as a Mechanism to Maintain and Facilitate Recovery of Forest Cover: Examining Reforestation, Forest Maintenance and Productivity in UgandabackgroundThis study highlights the use of parks as a tool for restoration and forest maintenance with a focus on Kibale National Park in Uganda. The authors assess methodological approaches and limitations with current techniques to study land cover change. Research Goals & MethodsLandcover analyses were conducted to determine the extent and spatial distribution of temporal forest change and to provide an initial analysis of forest cover change both within and around the park.

Survival and Growth of Seedlings of 19 Native Tree and Shrub Species Planted in Degraded Forest as Part of a Forest Restoration Project in Madagascar's HighlandsbackgroundThis study compares the survival rates of 19 native tree and shrub species grown in a forest restoration project in Madagascar’s highlands. The study results are used to compare the survival of relatively short seedlings compared to relatively tall seedlings for all species combined in order to test the importance of seedling size for restoration.

Effect of Taungya on Regeneration of Endemic Forest Tree Species in Nigeria: Edo State Nigeria as a Case StudybackgroundThis study aims to investigate the number of native species that can regenerate under natural conditions in a 3-year Taungya system in Edo State, Nigeria. Taungya is an agroforestry system that combines forestry practices with agriculture and agriculture-related activities. Open access copy available |
Consequences of plantation harvest during tropical forest restoration in UgandaBackgroundTimber plantations have recently received considerable attention as a forest restoration strategy for heavily degraded lands in the humid tropics. Plantations can facilitate secondary forest regrowth by providing an understory environment more favorable for native plant recruitment than unmanaged degraded habitats. This study explores how using plantations as a restoration tool affects forest succession; how initial floristics affect successional pathways; and the effect of fire exclusion or other interventions.

Floristic Composition, Structure and Natural Regeneration in a Moist Semi-Deciduous Forest following Anthropogenic Disturbances and Plant InvasionbackgroundThis study examines the floristic composition, structure and natural regeneration in three forest types: disturbed forest (DF), undisturbed forest (UF), and disturbed-invaded forest (DIF) in Tinte Bepo forest reserve in Ghana. In addition, this study also considers how anthropogenic disturbances and plant invasion affect plant species composition. Open access copy available |
Fire Control as a Simple Means of Promoting Tropical Forest RestorationbackgroundThis study investigates whether or not fire exclusion allows grasslands to regenerate to forest in a timeframe suitable for reforestation efforts. The researchers compare tree species richness, dbh, diameter at ground height (DGH), and total woody biomass accumulation in 2 plots that have been protected from fire. They measure the size and amount of above ground biomass in plots that have been protected from fire for 12 and 32 years respectively in Kibale National Park, Uganda. Open access copy available |
Desempeño de tres especies arbóreas nativas del bosque tropical caducifolio en un proyecto de restauración ecológica en el Cerro Punhuato, Morelia, Michoacán (Performance of native tree species)Españolobjetivos y metodologíaEl estudio tiene como objetivo evaluar la supervivencia y el crecimiento de tres especies arbóreas nativas del bosque tropical caducifolio (Albizia plurijuga, Ceiba aesculifolia y Cedrela dugesii), en el área natural protegida Cerro Punhuato, en Morelia, Michoacán. Asimismo, se busca estudiar el potencial de la planta arbustiva Eysenhardtia polystachya como planta nodriza. Open access copy available |
Los árboles en la ganadería del trópico seco (Trees in agroforestry systems in the tropical dry forest)Los autores destacan la importancia de la vegetación arbórea nativa, tanto de especies leguminosas como no leguminosas, manejadas ya sea de forma empírica o siguiendo un método científico de algunos sistemas silvopastoriles presentes en el estado de Colima, México. Se enfatizan las características nutricionales tanto del follaje como de los frutos. Se describen algunos sistemas silvopastoriles, entre ellos: el manejo de cocotero en la región costera, los árboles en los potreros, experiencias con el manejo de los bancos de proteína, la utilización de cercas vivas y algunas asociaciones forrajeras. Los autores destacan la diversidad Open access copy available |
