Dalbergia Sissoo Mortality in Bangladesh Plantations: Correlations with Environmental and Management ParametersbackgroundThis research seeks to correlate environmental and plantation conditions with the widespread mortality of Dalbergia sissoo trees planted in Bangladesh. Goals & MethodsIn order to understand the relationship between D. sissoo mortality and environmental and plantation characteristics, the authors examined 72 mixed plantations across five districts in Bangladesh.

Initial Performance and Reforestation Potential of 24 Tropical Tree Species Planted Across a Precipitation Gradient in the Republic of PanamabackgroundThe authors of this study planted trees from 22 native species and two exotic species to use in selection trials testing the growth and survivability of trees in plantations in three different sites. Research Goals & MethodsThe sites were chosen for their precipitation gradient from Soberania National Park (2226mm mean annual rainfall), Los Santos (1946mm rainfall), and Rio Hato (1107mm rainfall). Survival, basal diameter, height, crown diameter and wood volume index (VI) were calculated after two years of growth. Available with subscription or purchase |
Rehabilitating Degraded Forest Land in Central Vietnam with Mixed Native Species PlantingsBackgroundThis study considers the imepdiments to reforestation presented by grasses such as Imperata cylindrica. It specifically examined the use of Acacia as a nurse crop to overcome some of the ecological and economic impediments to reforestation of degraded areas dominated by grasses.

Seedling survival and growth of native tree species in pastures: Implications for dry tropical forest rehabilitation in central PanamaBackgroundEnrichment planting of tree seedlings is a method for accelerating reforestation of pastures in Central America. Persistent presence of cattle can be an impediment to the survival of unprotected seedlings, although cattle may also be a source of nutrients. Grasses can also cause competitive pressure on newly planted seedlings. Open access copy available |
Between and Within-Site Comparisons of Structural and Physiological Characteristics and Foliar Nutrient Content of 14 Tree Species at a Wet, Fertile Site and a Dry, Infertile Site in PanamabackgroundThis study seeks to analyze how stress resulting from different amounts of precipitation and soil nutrients affects tree growth. The study hypothesized that tree structure and physiology as well as foliar nutrient content would be significantly different between the sites, and trees at the wet, fertile sites would perform better. Secondly, the study hypothesized finding a greater variability of integrated tree growth at the drier site, as plant stress is expected to accentuate differences in performance. Lastly, it was hypothesized that leaf mass area and foliar N would predict photosynthetic capacity. Available with subscription or purchase |
Biomass Distribution Among Tropical Tree Species Grown Under Differing Regional ClimatesbackgroundThis study presents results from species selection trials in Panama as part of the PRORENA project, which examined the most effective species and methods for Panamanian government-supported reforestation projects. research goal & methodsIn 2003, 16 native and 2 exotic species were planted in single-species plots with a 3m x 3m spacing of trees at two different sites (one seasonally wet, one more dry). All plots were thinned to 50% of their original density at two years after plantation establishment, and the thinned trees were measured for biomass and biomass partitioning.

Growth, carbon sequestration, and management of native tree plantations in humid regions of Costa RicaBackgroundThe Costa Rican government has provided incentives for reforestation programs since 1986 and initiated a Payment for Environmental Services program in 1996. These incentives yielded native species reforestation programs throughout the country. This study examines growth, carbon sequestration, and management of seven native tree species (Vochysia guatemalensis, Vochysia ferruginea, Hyeronima alchorneoides, Calophyllum brasiliense, Terminalia amazonia, Virola koschnyi, and Dipteryx panamensis) in single-species plantations managed by small landowners.

Evaluation of 15 Indigenous and Introduced Species for Reforestation and Agroforestry in Northeastern MexicoBackgroundThis article presents the results of a reforestation study in the Sierra Madre Mexico. Research Goals & MethodsTen native species (Pithecellobium, Prosopis, Helietta, Cordia, and Acacia spp.) and five exotic species (Leucaena and Eucalyptus spp.) were raised in a nursery and planted in June of 1984. Measurements took place between 1985 and 1999. Available with subscription or purchase |
Cloning of erect, thornless, non-browsed nitrogen fixing trees of Haiti's principal fuelwood species (Prosopis juliflora)BackgroundProsopis juliflora (bayawon in Creole) is a spiny leguminous tree that is used throughout arid regions of Africa, Asia, and the Caribbean for fuelwood and fodder. Due to its genetic diversity, pod protein and carbohydrate content varies widely, suggesting advantages of clonal reproduction. This Haiti-based study tests exotic and native varieties of Prosopis for growth rates. Open access copy available |
