Crecimiento Comparativo de Especies Nativas y Teca plantadas en parcelas puras y mixEspañolantecedentesEl interés por la reforestación como una alternativa a la deforestación se ha incrementado en los últimos años en Panamá. Sin embargo, en las iniciativas de reforestación las exigencias de las plantas no son usualmente consideradas y las mas utilizadas son especies introducidas. Open access copy available |

A Survey of Small-Scale Farmers Using Trees in Pastures in Herrera Province, PanamabackgroundThe Herrera Province on the Azuero Peninsula of Panamá has experienced significant deforestation for the purpose of cattle ranching. research goal & methodsThe goal of the study was to determine more information about the use of trees in smallholder cow pastures. Herreran pasture owners were interviewed about the different uses for trees in their pastures as well as the variety of tree species. Available with subscription or purchase |
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.

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.

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 |
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.
