  abstract = {{W}ildfire has been recognized as one of the most ubiquitous disturbance agents to impact on natural environments. {I}n this study, our main objective was to propose a modeling approach to investigate the potential impact of wildfire on biodiversity. {T}he method is illustrated with an application example in {N}ew {C}aledonia where conservation and sustainable biodiversity management represent an important challenge. {F}irstly, a biodiversity loss index, including the diversity and the vulnerability indexes, was calculated for every vegetation unit in {N}ew {C}aledonia and mapped according to its distribution over the {N}ew {C}aledonian mainland. {T}hen, based on spatially explicit fire behavior simulations (using the {FLAMMAP} software) and fire ignition probabilities, two original fire risk assessment approaches were proposed: a one-off event model and a multi-event burn probability model. {T}he spatial distribution of fire risk across {N}ew {C}aledonia was similar for both indices with very small localized spots having high risk. {T}he patterns relating to highest risk are all located around the remaining sclerophyll forest fragments and are representing 0.012% of the mainland surface. {A} small part of maquis and areas adjacent to dense humid forest on ultramafic substrates should also be monitored. {V}egetation interfaces between secondary and primary units displayed high risk and should represent priority zones for fire effects mitigation. {L}ow fire ignition probability in anthropogenic-free areas decreases drastically the risk. {A} one-off event associated risk allowed localizing of the most likely ignition areas with potential for extensive damage. {E}mergency actions could aim limiting specific fire spread known to have high impact or consist of on targeting high risk areas to limit one-off fire ignitions. {S}patially explicit information on burning probability is necessary for setting strategic fire and fuel management planning. {B}oth risk indices provide clues to preserve {N}ew {C}aledonia hot spot of biodiversity facing wildfires.},
