Previous research has demonstrated that remote sensing can provide spectral information related to vegetation moisture variations essential for estimating live fuel moisture content (LFMC), but accuracy and timeliness still present challenges to using this information operationally. Consequently, many regional administrations are investing importan...
Article
Vertical fuel structure is critical for fire hazard assessment in forest ecosystems. Forest stands with ladder fuels are more prone to crown fires because of canopy fuel continuity. However, characterization of ladder fuels is difficult in the field and few studies have developed explicit measurement procedures to account for these hazardous fuel s...

Spain is one of the Mediterranean countries most severely affected by wildfires during the last 30 years, despite enhanced fire suppression efforts. At present, forest area is increasing more in Spain than in any other European country, and also has one of the highest densities of fire ignitions. However, forest management plans have been developed...

Live fuel moisture content (LFMC) influences many fire-related aspects, including flammability, ignition, and combustion. In addition, fire spread models are highly sensitive to LFMC values. Despite its importance, LFMC estimation is still elusive due to its dependence on plant species traits, local conditions, and weather patterns. Although LFMC m...

Shrubland are one of the main communities affected by wildland fires, both in forested and unforested areas. However, empirical models predicting fire behaviour in these communities are scarce. One reason explaining the lack of knowledge is the difficulty of obtaining data to develop these kinds of models. Wind tunnel experimental fires have been c...
