Árboles Nativos para Predios GanaderosEspañolAntecedentesComo parte del Proyecto Ganadería Colombiana Sostenible, cerca de 1.5 millones de árboles nativos de alto valor ecológico fueron entregados a ganaderos de cinco regiones colombianas para integrar en sus fincas y sistemas pastoriles. Quince de esas especies de árbol nativo fueron seleccionadas para discutir en detalle en este libro, permitiendo así la divulgación del conocimiento sobre la importancia de los árboles nativos en la ganadería sostenible.

Les légumineuses arborescentes dans les systèmes de production des zones sèches de Côte d'Ivoire (Arborescent leguminous plants in the production systems of dry zonesin Côte d’Ivoire)The authors saught to identify woody legumes adapted to dry conditions of Côte d’Ivoire and to determine their success in reforestation. They describe 18 species of woody plants that were successful seven years after planting while also noting several species that responded well to coppicing under tropical dry conditions.

Hacia una silvicultura sostenible en el trópico seco: el caso de la Finca Piedra Rala, Nicaragua (Towards sustainable silviculture in dry tropical forests: the case of Finca Piedra Rala, Nicaragua)El autor explica la experiencia de los productores en el manejo racional de pequeñas áreas de bosque tropical seco y analiza como la silvicultura racional tiene una capacidad de regeneración de los bosques naturales poco productivos en la zona del Pacífico de Nicaragua. En la finca estudiada, el bosque es sometido a un sistema de aprovechamiento tradicional, desarrollado como una iniciativa del propietario. Open access copy available |
Strategies for the Recovery of Degraded Ecosystems: Experiences from Latin AmericabackgroundThis paper reviews the rehabilitation potential of native species forest plantations in lowland Costa Rica, the Atlantic Forest of Bahia, Brazil, and sub-tropical Argentina. Native species can improve forest regeneration where soils are degraded and where sources of propagules are limited. While most tropical plantations are dominated by exotic species, native trees may be more appropriate because they are better adapted to the local environment, are already familiar to local farmers, and their propagules are locally available.

The Structure and Composition of a Tropical Dry Forest Landscape After Land Clearance; Azuero Peninsula, PanamabackgroundThis article describes natural regeneration that has occured in five different habitat types in the Azuero Peninsula of Panama. These habitat types include active pasture, 2-yr abandoned pasture, 5-yr abandoned pasture, forest riparian zones, and a secondary forest fragment. This region is characterized by agricultural and cattle ranching landcapes in areas that previously were tropical dry forest (1700 mm rainfall per year) until the mid-20th century and have recently been undergoing rapid turnover in land ownership.

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 |
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 |
Early Species Selection for Tropical Reforestation: A Consideration of StabilitybackgroundThis study describes a screening of timber species planted in abandoned pasture sites to understand the effect of different site conditions on tree growth and to determine the species that grew with the highest variation. Research Goals & MethodsThe author looks at genotype environment to evaluate stability of genotypes and genotypes with the ability to perform consistently in multiple site conditions.
