Notas sobre el diseño de plantaciones de restauración (Notes about the design of plantains for restoration)EspañolAntecedentesLa restauración forestal es compleja, tanto en teoría como en práctica. La incógnita de los ecosistemas de referencia es una que muchos investigadores y profesionales se han planteado y pocos han podido descifrar. ¿Deberíamos restaurar los bosques a una condición prístina? ¿Qué deberíamos utilizar como sistema de referencia? Esto, entre otras consideraciones, se explora en las observaciones del autor sobre el proceso de diseño de las plantaciones de restauración. Open access copy available |

Restoration of Dry Afromontane forest using pioneer shrubs as nurse-plants for Olea europaea ssp. cuspidataBackgroundShrubs are often considered competitive barriers for seedlings planted in reforestation programs, although they can facilitate tree recruitment, especially in ecosystems under high abiotic stress. An alternative reforestation technique using pioneer shrubs as nurse-plants for Olea europaea ssp. cuspidata was tested in exclosures in northern Ethiopia. Open access copy available |
