Forty-two trees were destructively sampled and their crown fuels were weighed separately for each fuel category. Crown fuel components, were separated into size classes and regression equations that estimate crown fuel load by diameter class were derived. The allometric equation y = ax b with diameter at breast height as the single predictor was chosen, because the addition of other parameters did not decrease the residual sum of squares significantly. The R 2 adj. values were relative high (R 2 adj. = 0.68 -0.82) in all cases. Diameter at breast height was the most significant determinant of crown fuel biomass. The aerial fuels that are consumed during crown fires (i.e. needles and twigs with diameter less than 0.63 cm) comprised 36.3% of the total crown weight. Crown fuels, distributed as follows: needles 28.2%, branches with 0.0-0.63 cm diameter 12.1%, 0.64-2.5-cm diameter 23.7%, 2.51-7.5-cm diameter 20.4%, and >7.5-cm diameter 15.6%. The equations provide quantitative fuel biomass attributes for use in crown fire behaviour models, fire management and carbon assessment in Black pine plantations in Bulgaria.

In this paper, we present the main activities of the BEYOND Center of Excellence run by NOA, related to fire detection, fire monitoring and rapid mapping, along with damage assessment services using satellite remote sensing techniques supported by state-of-the-art information technologies. The focus lies in integrating fully automatic processing chains into dedicated systems that offer stakeholders online access to robust, accurate and fully operational Web-based tools to assist the Emergency Response and Emergency Support actions.

In this paper we demonstrate the accuracy assessment of "ArcFUEL" project which has delivered a complete, up-to-date, methodology for Fuel Classification Mapping (FCM on a Web-Geodatabase) based on "readily available" data, harmonized, accessible & interoperable according to INSPIRE principles, for the Mediterranean Region. The fuel layer has been evaluated in terms of spatial and thematic thematic accuracy by employing an extensive field campaign in Portugal and Greece and standard photointerpretation procedures. For Greece, the overall accuracy was found to be 80.59 % , while the Kappa value was 0.74. For Portugal the overall accuracy was found to be 67% and the Kappa value was 0.63.The spatial fuel maps is an end-product essential for computing spatial fuel hazard, fire risk and simulation, fire growth and intensity and post fire effects across a landscape at national and regional scale.

We applied the Minimum Travel Time fire simulation algorithm using the FlamMap and ArcFuels tools to characterize the potential response of the wildfire risk to a range of different burning scenarios. We created site-specific fuel models of the study area by measuring the field fuel parameters in representative natural fuel complexes, and we determined the spatial extent of the different fuel types and residential structures in the study area using photointerpretation procedures of large scale natural color orthophotographs. The results included simulated spatially explicit fire risk components along with wildfire risk exposure analysis and the expected n...
