  abstract = {{D}ata on paleofire activity in southeastern {F}rance during the {H}olocene are still lacking thus limiting our capability to anticipate fire regime shifts under climate change. {H}ere, we present a 8.2 ky-long high-resolution time-series of microscopic charcoal (microcharcoal) particles from a marine sediment core retrieved from the {R}hone prodelta, in the {G}ulf of {L}ions ({NW} {M}editerranean {S}ea). {F}ire frequency, episodes, size and types of burnt vegetation were determined by quantifying microcharcoal and analysing its morphometry. {O}ur results indicate an increase in biomass burning and fire frequency combined with a decrease in the mean elongation ratio from the {N}orthgrippian (8.2-4.2 ka) to the {M}eghalayan (4.2-0 ka) stage. {T}his pattern is interpreted as reflecting a shift from the burning of graminoids in closed mesophytic forests during the {N}orthgrippian to the burning of shrub communities in open {M}editerranean habitats during the {M}eghalayan. {W}e also identified 20 fire episodes over the past 8.2 ka, occasionally coinciding with human occupations. {L}arge fires occurred during cold events and summer droughts conditions of the {N}orthgrippian. {W}e relate this finding to negative phases of the {N}orth {A}tlantic {O}scillation ({NAO}) and increased fuel load under wet winter conditions and fuel flammability under dry and strong summer winds. {B}esides climate and vegetation, human activity is likely to be an additional driver of fire during the {M}eghalayan. {S}outheastern {F}rance is currently identified as a region with a high wind-driven fire risk, although its fire regime analysis is biased by intensive fire suppression. {W}e suggest that wind-driven large fires is an inherent element of fire and weather patterns in this area rather than the result of fire suppression strategies leading to uncontrollable large fires.},
