<p>In the light of climate change both number and duration of droughts and heat waves in Central Europe are projected to increase. Such developments will affect vegetative fuels and may alter the local fire regime. Wildfire is expected to expand into new, traditionally non-fire-prone regions such as the temperate zone. While having been a negligible threat until recently, more and larger fires can be anticipated in Central Europe.</p><p>Integrated fire hazard is a valuable metric for forest and fire management and may support safety planning efforts and decision-making. It combines flame length and burn probability which can be derived from fire spread simulations. These rely on multiple spatial variables related to topography, climate and fuels. Information on fuels is thereby most challenging to acquire as they vary significantly in space and time. Modeling surface and canopy fuel variables requires extensive field data. Both can strongly benefit from incorporating remote sensing data in their prediction.</p><p>We present a comprehensive assessment of wildfire fuels, behavior and hazard for a small managed temperate forest in north-western Germany. Dominant species present include Scots pine (Pinus sylvestris), European Beech (Fagus sylvatica) and red oak (Quercus rubra). Located in a densely populated region the study area is highly frequented for recreational purposes.</p><p>...
