Sustainable Harvest International Reforestation: Annual Report FY2008BackgroundThe mission of Sustainable Harvest International's reforestation work is to empower local farmers by giving them the knowledge and equipment to improve degraded lands, rebuild diversity in the forest ecosystems, and benefit from the planting of trees.

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 |
Impacts of Herbicide Application and Mechanical Cleanings on Growth and Mortality of Two Timber Species in Saccharum spontaneum Grasslands of the Panama Canal WatershedbackgroundThis study evaluates the effectiveness of weed control treatments (herbicide application and mechanical cleanings) in promoting the growth and survival of the exotic tree species Tectona grandis and the native tree species Terminalia amazonia.

Root architecture and allocation patterns of eight native tropical species with different successional status used in open-grown mixed plantations in PanamaBackgroundWhile an increasing number of native tropical trees are under study for reforestation and commercial plantations, the majority of studies on trees in the tropics have concentrated on the aboveground aspects of tree growth. This study investigates biomass allocation and root architecture of eight tropical species with different successional status. Open access copy available |
Tree planting by small producers in the tropics: A comparative study of Brazil and PanamaBackgroundForest regrowth is a widespread phenomenon across the tropical forest latitudes. Such reforestation takes place in the wake of land abandonment, occurs cyclically in a rotational agricultural system, and may result from the deliberate planting of trees by farmers. Although less extensive than successional forest regeneration, tree planting by small farmers can have potentially important environmental impacts at both the site and global scale.

Carbon Forestry Project CO2OL Tropical MixBACKGROUNDDegraded land, originally forest land, later used for extensive cattle ranching, is reforested with mostly native tree species and gradually converted into mixed forests. The project provides for sustainable timber production and cocoa cultivation; protects biodiversity and restores a healthy forest ecosystem. The project reforests previously degraded pastureland with a mixture of native tree species to produce fine tropical timber, enrich the soil, save and filter water, sequester carbon, and contribute to the mitigation of climate change.
