Soil carbon differences among forest, agriculture, and secondary vegetation in lower montane EcuadorBackgroundChanges in land use and land cover may affect soil properties and processes. Conversion of forest to cultivation is assumed to result in a decrease in soil nutrients. In the lower montane region of Ecuador, shifting cultivation patterns mean that forest clearing is occurring simultaneously with recolonization of secondary vegetation on abandoned agricultural lands.

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.

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 |
Efecto de la zona de vida y la altitud en la mortalidad y adaptabilidad al primer año de especies forestales en la Cordillera Volcánica Central de Costa RicaEspañolAntecedentesEl entendimiento comprensivo de la restauración de bosques requiere de la comprensión del fenómeno de la mortalidad incluyendo su magnitud y ubicación espacial. En Costa Rica, no existe suficiente información capturando los efectos de climas pluviales sobre la mortalidad de especies forestales, especialmente en zonas altas. Open access copy available |

Reserva Encenillo, Fundacion Natura, ColombiaThis reserve is located in high montane forest of the Colombia Andes, designed to protect the locally important forest tree Weinmanniatomentosa (Encenillo in Spanish). The total size of the reserve is 135 ha of forest, and serves as a forest corridor in a matrix of pasture, potato, and remnant forest landscape. Open access copy available |
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.

Increasing Drought Sensitivity and Decline of Atlas Cedar (Cedrus atlantica) in the Moroccan Middle Atlas ForestsbackgroundSince the 1980s, severe droughts have influenced Atlas cedar mortality in Morocco. This study looked at relative contributions of tree characteristics and stand structure on the increment-growth and decline of Atlas cedar trees (Cedrus atlantica) in stands affected by past logging and heavy grazing.
