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.

Growth of native tree species planted in montane reforestation projects in the Colombian and Ecuadorian Andes differs among site and speciesBACKGROUNDTropical Andes in Columbia and Ecuador have been affected by forest clearance and degradation for several centuries. Agriculture has been the primary driver of land use change as well as mining to a lesser extent. To restore the degraded sites, native species have been used in various projects, however with little information on growth performance of the planted tree species in relation to site and soil nutrient status. A greater part of the northern Andes has volcanic ash derived soils. Available with subscription or purchase |
Restoration of the Cerros Orientales de Bogota - Jardin Botanico de BogotaThe Jose Celestino Mutis Botanic Garden of Bogota works with the Municipal government of Bogota in order to restore and rehabilitate various areas of forest habitat around the city of Bogota. The most extensive plantings are conducted in the Cerros Orientales, hills located on the outskirts of Bogota. This very steep mountain area had been cleared and was subject to severe erosion, and was planted with exotic pine and eucalyptus throughout the 19th and 20th century. Parts of this forest continue to be grazed for cattle, and many areas have also been invaded by the invasive European gorse (Ulex europaeus). Open access copy available |
Rio Bogota - Fundacion al verde vivoThis project attempts to restore riparian forest along the headwaters of the Rio Bogota, upstream of the city of Bogota. Since 2003, the Fundacion al verde vivo has worked with volunteers to plant trees along the riparian corridor. Many areas along the riverbanks were previously used for cattle pasture, leather tanneries, or other small constructions. Local laws require that certain distances of riparian buffer are maintained as forest, but these regulations are rarely enforced. Plantings are conducted in rows with 1-2 meter spacing. Alnus plantings from 2005 form a canopy, and mid-successional species of oak, Spanish cedar, and other highland Andean trees are planted in gaps and in the understory.

Laguna Pedro Palo - Reserva Tenasuca, ColombiaThis project is located in a community reserve outside of Bogota, Colombia, in montane Andean oak forest. Plantings are performed by members of the reserve association, which includes a small NGO and local landowners. 2-3 hectares were planted around a lake in 1998, these plantings were predominantly Andean oak (Quercus humboltii), this forest area reached canopy closure in 2010-2013. Reserve managers believe that this oak buffer area helps to maintain a constant water level of the lake, by recharging a continuous supply of groundwater throughout the year.

Forestry Project for the Basin of the Chinchiná River, an Environmental and Productive Alternative for the City and the RegionBackgroundOver the last century, Andean watershed within Colombia has faced threats of uncontrolled deforestation, which have been driven by a rapid expansion of agriculture and cattle grazing. It is imperative that these trends be halted and reversed, thus the FAO proposes the reforestation of watersheds, which will improve the regulation of hydaulic flows to populations living in and downstream from river basins. This project planning document describes one of these programs, PROCUENCA-FAO, which began in 2001 and focuses on the Chinchiná River watershed. Open access copy available |
