Spain is one of the Mediterranean countries most severely affected by wildfires during last 30 years, despite enhanced fire suppression efforts. At present, forest area increasing more in than any other European country, and also has highest densities ignitions. However, management plans have been developed for only 13% Spanish areas. The objective present study was to assess role fuel wildfire prevention Spain. Different techniques, including mechanical treatments, prescribed burning...
Previous research has demonstrated that remote sensing can provide spectral information related to vegetation moisture variations essential for estimating live fuel content (LFMC), but accuracy and timeliness still present challenges using this operationally. Consequently, many regional administrations are investing important resources in field campaigns LFMC monitoring, often focusing on indicator species reduce sampling time costs. This paper compares different approaches prediction of...
Fuel management techniques are commonly used in shrublands to reduce wildfire risk. However, more information about the ecological effects of these treatments is needed by managers and ecologists. In an effort address this need, we performed a replicated (4 replicates per treatment) 48-ha experiment northern California chaparral dominated Adenostoma fasciculatum determine two fuel reduction types (prescribed fire mastication) three different seasons treatment (fall, winter, spring) on shrub...
Fuel bulk density and fuel moisture content effects on fire rate of spread were assessed in shrub fuels, comparing experimental data observed outdoor wind tunnel burns predictions from the physically-based model FIRETEC. Statistical models for combined fitted to both simulated values using non-linear regression techniques. Results confirmed a significant decreasing effect power law laboratory simulations. However, showed lesser than simulations, suggesting difference effective drag. was...
An adapted bench-scale Mass Loss Calorimeter (MLC) device for evaluating forest fuel flammability and combustion properties is proposed. This fire test apparatus consists of an MLC fitted with a chimney containing thermopile. After the thermopile output has been calibrated by use methane burner, these data are used to quantify heat release, as alternative classical measurement oxygen consumption due combustion. The results showed good repeatability reasonable approximation HRR values...
Canopy fuel characterization is critical to assess fire hazard and potential severity in forest stands. Simulation tools provide useful information for prevention planning reduce wildfire impacts, provided that reliable maps exist at adequate spatial resolution. Free airborne LiDAR data are becoming available many countries providing an opportunity improve monitoring large scales. In this study, models were fitted estimate canopy base height (CBH), load (CFL) bulk density (CBD) from a pine...
The modification of fire regimes and their impact on vegetation recovery, soil properties, fuel structure are current key research areas that attempt to identify the thresholds vegetation’s susceptibility wildfires. This study aimed evaluate vulnerability Mediterranean pine forests (Pinus halepensis Mill. Pinus pinaster Aiton) wildfires, analyzing two major forest fires occurred in Yeste (Spain) 1994 2017, affecting over 14,000 3200 hectares, respectively. Four recovery regions were...
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, estimation is still elusive due dependence on plant species traits, local conditions, weather patterns. Although mapping from active synthetic aperture radar has increased over the past years, their utility for needs further analysis include additional areas characterized by...
Mechanical treatments are traditionally used to modify the fuel complex in shrubland, but information about their actual effectiveness reducing risk of wildfire initiation is scarce. The effects two mechanical (shrub clearing with crushing and manual removal) on flammability a shrubland community north-western Spain were compared. Three months after treatment, laboratory tests using point-ignition source conducted fine dead fuels analyse effect type treatment moisture content (FMC) under...
Three-dimensional (3D) data from airborne laser scanning (ALS) and, more recently, digital aerial photogrammetry (DAP) have been successfully used to model forest attributes. While multi-temporal, wall-to-wall ALS is not usually available, imagery regularly acquired in many regions. Thus, the combination of and DAP provide a sufficient temporal resolution properly monitor forests. However, field needed fit new attribute models for each 3D acquisition, which always affordable. In this study,...
Estimating live fuel moisture content (LFMC) is critical for assessing vegetation flammability and predicting potential fire behaviour, thus providing relevant information wildfire prevention management. Previous research has demonstrated that empirical modelling based on spectral data derived from remote sensing useful retrieving LFMC. However, these types of models are often very site-specific generally considered difficult to extrapolate. In the present study, we analysed performance...
Wildfires represent one of the major ecological disasters with significant repercussions for terrestrial ecosystems (loss biodiversity, material damages, erosion, etc). Using LiDAR (Light Detection and Ranging) technology allows large amounts forest measurements data to be obtained, such as size volume, biomass, canopy cover, heights, among others. It also quantify some damage caused by fires comparing point clouds at two different times (before after fire). By correlating in situ...
Experimental tests were carried out with an adapted bench-scale mass loss calorimeter (MLC) and also in outdoor wind tunnel to estimate the heat release rate (HRR) of a forest fuel bed. The MLC apparatus uses calibrated thermopile quantify HRR, as alternative classical measurement oxygen consumption due combustion. Additional calibration thermocouples measure gas temperatures enabled estimation HRR experimental burnings conducted tunnel. results showed reasonable agreement between peak...
Fuel management is one of the main challenges for wildfire prevention in Mediterranean region, where wildfires have important environmental and socioeconomic effects. Different treatments are usually applied fire-prone shrubland to try modify its flammability. However, a knowledge gap on effectiveness fuel techniques still exists. We studied effects two mechanical (shrub crushing shrub clearing with removal) prescribed burning, fire behaviour, compared them untreated vegetation. Experimental...
Fuel management is commonly used to reduce fire risk in fire-prone shrubland, but information about the real efficacy of different techniques scarce. In this study, we assessed laboratory effects treatment types on initiation a mixed heathland. The two mechanical treatments and prescribed burning were compared with untreated vegetation. Flammability tests performed samples regenerated shrubs fine ground fuels present 2 years after treatments. Results indicate that all effective reducing...
Shrubland are one of the main communities affected by wildland fires, both in forested and unforested areas.However, empirical models predicting fire behaviour these scarce.One reason explaining lack knowledge is difficulty obtaining data to develop kinds models.Wind tunnel experimental fires have been carried out different shrubland fuel complexes (Ulex europaeus L. Pterospartum tridentatum (L.) Willk.)collected Galicia (NW Spain).Rate spread recorded laboratory tests compared with...
