Towards recovery of native dry forest in the Colombian Andes: a plantation experiment for ecological restorationBackgroundRegeneration of native forest after disturbances, especially in arid and semi-arid regions, often progresses slowly or is arrested at a successional stage. This study evaluates the effectiveness of native tree plantings as a restoration strategy in a semi-arid Andean valley. Open access copy available |
Reforestation with the Native Tree Alnus acuminata: Effects on Phytodiversity and Species Richness in an Upper Montane Rain Forest Area of ColombiaBackgroundThis study takes place in the western cordillera in Colombia (Quindio). Upper montane forest is dominated by large Weinmannia (Alnus acuminata) plantations established from 1977-1978 on abandoned agricultural and grazing land (for erosion control), and secondary forest fragments that naturally colonized abandoned agricultural areas.

Estrategias para la restauración ecológica del bosque altoandino. El caso de la reserva municipal de Cogua. (Strategies for the ecological restoration of the high Andean forest - the case of the municipal reserve of Cogua)Entre los años 2002-2006 se realizó una restauración de potreros degradados en la reserva forestal municipal de Cogua (departamento de Cundinamarca - páramo alto - 2900-3630 m). Se hizo la restauración con 1) remoción de Chusquea scandens; 2) creación de perchas artificiales para aves (para facilitar lluvia de semillas); 3) siembras de especies selectivas Se notó invasión de Ulex europaeus y la herbivoría por Cavia porcellus (curí) como barreras para la restauración. Aún no se ha realizado una evaluación cuantitativa. Open access copy available |
Paying for Biodiversity Conservation Services in Agricultural LandscapesbackgroundThis document describes the genesis for the World Bank GEF project from 2002-2007 to implement payments for ecosystem services for silvo-pastoral systems in Colombia, Nicaragua, and Costa Rica. The payments were designed to compensate for biodiversity services: international donor money would be exchanged for the international environmental service of biodiversity.

Recuperación estructural en bosques sucesionales andinos de Porce, Antioquia, Colombia (Structural recuperation in secondary successional Andean forests in Porce, Antioquia, Colombia)EspañolAntecedentesDurante décadas los bosques de la región de Porce (Antioquia, Colombia) han sido talados y quemados para establecer fincas ganaderas y, en menor proporción, agricultura. Este tipo de prácticas pudieron ser decisivas para el proceso sucesional del sitio, ya que la degradación producida en el suelo pudo afectar las características estructurales de la vegetación secundaria establecida.

InVEST: A Tool for Integrating Ecosystem Services into Policy and Decision-MakingbackgroundThis document explains the InVEST tool, an ecosystem service model (via a software program) used to geographically map the provision of ecosystem services and how they can be affected by development and policies. The model, designed by the Natural Capital Project (collaboration of WWF, TNC, the University of Minnesota, and Stanford University), is intended for planners to maximize the benefit from activities such as reforestation.

Effect of Land Prices, Transportation Costs, and Site Productivity on Timber Investment Returns for Pine Plantations in ColombiabackgroundThis study assesses the importance of land costs, site quality, and forest location on financial returns of forestry investments. Goals & MethodsThe factors mentioned above were analyzed using data from pine plantations in the Andean region of Colombia. Researchers determined site quality based on annual growth rates and they calculated comparative return on forest investment based on sales of wood, market prices, wood transport costs, and bare land costs.

Propagación in vitro de material seleccionado de Tabebuia rosea y Cordia alliodora (In vitro propagation of selected material from Tabebuia rosea and Cordia alliodora)EspañolAntecedentesLa aplicación de la micropropagación y otras técnicas biotecnológicas a las especies forestales maderables ha representado un enfoque útil para aumentar el número de plantas necesarias para el establecimiento de plantaciones de restauración. En Colombia se está investigando la integración de esta tecnología para la siembra de importantes especies maderables nativas como Tabebuia rosea y Cordia alliodora. Open access copy available |
