AB In this study we combine information from aerial LIDAR and hemisphericalimages taken in the field with ForeStereo—a forest inventory device—to assess thevulnerability and to design conservation strategies for endangered Mediterranean firforests based on the mapping of fire risk and canopy structure spatial variability.We focused on the largest continuous remnant population of the endangered treespecies Abies pinsapo Boiss. spanning 252 ha in Sierra de las Nieves National Park(South Andalusia, Spain). We established 49 sampling plots over the study area.Stand structure variables were derived from ForeStereo device, a proximal sensingtechnology for tree diameter, height and crown dimensions and stand crown coverand basal area retrieval from stereoscopic hemispherical images photogrammetry.With this information, we developed regression models with airborne LIDAR data(spatial resolution of 0.5 points∙m−2). Thereafter, six fuel models were fitted to theplots according to the UCO40 classification criteria, and then the entire area wasclassified using the Nearest Neighbor algorithm on Sentinel imagery (overallaccuracy of 0.56 and a KIA-Kappa Coefficient of 0.46). FlamMap software was usedfor fire simulation scenarios based on fuel models, stand structure, and terrain data.Besides the fire simulation, we analyzed canopy structure to assess the status andvulnerability of this fir population. The assessment shows a secondary growth forestthat has an increasing presence of fuel models with the potential for high fire spreadrate fire and burn probability. Our methodological approach has the potential to beintegrated as a support tool for the adaptive management and conservation ofA. pinsapo across its whole distribution area (<4,000 ha), as well as for otherendangered circum-Mediterranean fir forests, as A. numidica de Lannoy andA. pinsapo marocana Trab. in North Africa.
