"Fire regime" has become, in recent decades, a key concept in many scientific domains. In spite of its wide spread use, the concept still lacks a clear and wide established definition. Many believe that it was first discussed in a famous report on national park management in the United States, and that it may be simply defined as a selection of a few(More)
Leaf to sapwood area ratio in Castanea sativa is constant within a branch, but decreases with branch height. We propose a modeling approach to mitigate this effect. The pipe model theory postulates the constancy of the relationship between leaf to sapwood area among single parts and for a whole tree. By analyzing 218 branches belonging to 67 different(More)
Chestnut (Castanea sativa Mill.) coppice is a man-made forest type that has been managed for centuries in short rotations to rapidly produce woody biomass. These forests, which nowadays cover significant areas within Europe, experience a general neglect and are subsequently being abandoned. Most of them are now over-aged, very dense, and highly monotone.(More)
The tree of heaven (Ailanthus altissima (Mill.) Swingle) is considered to be an early-successional, gap-obligate pioneer species with vigorous height growth, low shade tolerance, early fecundity and large seed production. It is a highly invasive species in many temperate and Mediterranean ecosystems outside its natural range, especially after disturbance.(More)
Biomass allocation in Castanea sativa varies according to the environmental conditions. Specifically, leaf-to-sapwood area ratio is higher on sites with good water supplies and lower in water-stressed conditions. Ecological plasticity allows organisms to adapt and to cope with environmental conditions. This is a key trait for species with long live span,(More)
Beech (Fagus sylvatica L.) forests covering relief-rich terrain often provide direct protection from rockfall for humans and their property. However, the efficacy in protecting against such hazards may abruptly and substantially change after disturbances such as fires, windthrows, avalanches and insect outbreaks. To date, there is little known about the(More)
Fire regimes are strongly related to weather conditions that directly and indirectly influence fire ignition and propagation. Identifying the most important meteorological fire drivers is thus fundamental for daily fire risk forecasting. In this context, several fire weather indices have been developed focussing mainly on fire-related local weather(More)
