Article Title：Influence of historical factors on the current vegetation: the case of feudal mottes in forest habitats (Picardy, France)
Abstract：
Historical factors are rarely taken into account despite their high potential for the understanding of vegetation determinism. This study aims to propose a method to stress the importance of historical factors on the current vegetation. It consists in a comparative socio-ecological analysis of archaeological sites versus control sites, both being in the same ecological conditions for climate, substrate and biotic pressure at present. This approach has been applied to a set of ten feudal mottes located in some forests of the Picardie district (France). Our results show that 1) the feudal mottes support a neutrophilous, eutrophic and semi-heliotropic vegetation though the surrounding forest vegetation is markly acidic, mesotrophic and sciaphilous, 2) specific richness trends to be higher on the mottes, 3) a few species for which the status of <> is questioned were also observed.
