Controlling vegetation fuels around human settlements is a crucial strategy for reducing fire severity in forests, buildings and infrastructure, as well as protecting human lives. Each country has its own regulations in this respect, but they all have in common that by reducing fuel load, we in turn reduce the intensity and severity of the fire. Th...
Los sistemas de cubierta forestal continua o CCF, del inglés “continuous cover forestry” promueven la silvicultura conocida como “próxima a la naturaleza” y están basados en principios como la creación y la permanencia de una estructura irregular para la masa forestal mediante tratamientos silvícolas como las cortas de selección individual o entres...

Timber and biodiversity are considered two antagonistic ecosystem services (ES), largely influenced by silviculture and site ecological conditions. In order to address the trade-offs between these two ES over time, we performed a retrospective study at compartment level in the Pinus sylvestris forests of the Spanish Central Mountain System. Archiva...

Sustainable forest management has been approached on many occasions by defining and subsequently
measuring a set of initially accepted indicators. This methodology permits the aggregation of multiple
goods and services with heterogeneous characteristics into forest management. However, the calculation
of these indicators has usually been static. Wh...
