A Case Study Assessment of Agroforestry: The Panama Canal WatershedbackgroundThis article provides a qualitative assessment of three agroforestry sites in the Panama Canal watershed based on management objectives, project life span, incentives, technology, economic feasibility, community involvement, and extension. It seeks to guide sustainable forest management options for the Panamanian government. conclusions & takeawaysEnvironmental managers should view agroforestry as a production system and consider this in its social and biophysical context.

The Tree Planting and Protecting Culture of Cattle Ranchers and Small-Scale Agriculturalists in Rural Panama: Opportunities for Reforestation and Land RestorationbackgroundThis study examines the relationship between farmers and trees in the tropical dry forest in two rural communities of Panama, focusing on the uses and values that small landholders assign to local tree species, both native and exotic.

Local and Regional Environmental Variation Influences the Growth of Tropical Trees in Selection Trials in the Republic of PanamabackgroundThis study evaluates the effect of varying site conditions on the basal area of 21 neotropical and 2 exotic tree species at three different sites in Panama. Research Goals & MethodsSeedlings were planted in 2003 in randomized blocks and measured for basal diameter, height, live crown length, and crown diameter each year from 2004 to 2006.

The Agua Salud Project, Central PanamaBackgroundThe Agua Salud Project is located in the watershed that includes and surrounds the Panama Canal, an engineering feat that largely relies on natural hydrological systems. Much of this watershed has been deforested, thus an official policy has been put into place to reforest and regain ecosystem services. This project seeks to utilize the globalize role of the canal to bring attention to the ecosystem services of the region. Open access copy available |
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.

Barriers to Forest Regeneration of Deforested and Abandoned Land in PanamaBackgroundThis article presents research findings on the effect of four limiting factors on tree regeneration: competition with the exotic grass Saccharum spontanaeum, seed dispersal limitation, fire, and soil nutrient deficiency. Research Goals & MethodsTreatments included prescribed grass cutting and burning, as well as the placement of plots at different distances from adjacent forest. Open access copy available |
Factors Affecting Community Composition of Forest Regeneration in Deforested, Abandoned Land in PanamabackgroundThis study tests how Saccharum spontaneum, an invasive grass, affects early forest succession and community composition in an area of previously abandoned pasture.

Can Native Tree Species Plantations in Panama Compete with Teak Plantations? An Economic EstimationbackgroundPanama has high rates of primary forest conversion, resulting in depleted timber resources. In response, the timber plantation industry is growing to meet demand, often with non-native species. This study compares the economic feasibility of using native tree species vs non-native species for plantation forestry. Open access copy available |
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 |
