Dynamique des populations de robinier faux-acacia (Robinia pseudoacacia) en régions Nord-Pas-de-Calais et Picardie

Abstract : Black locust, Robinia pseudoacacia, has undeniable qualities, particularly in silviculture: hard wood, rapid growth, etc. Professionals wish to develop an industry of timber. Nevertheless, naturalists’ communities want more information about its potential invasiveness. The purpose of this study is to better understand what situations are susceptible to invasions. In this way, we could distinguish management schemes in Nord-Pas-de-Calais and Picardie. About the methodology, we selected sites, hosting black locust, representative sample of the area. At each site, a transect was placing, half in population of black locust and half in an adjacent stand. This is to assess regeneration and dispersion of black locust. In addition, dendrology and pedology data were collected in each stand. This study allows us to say that black locust is not invasive inside forestry in Nord- Pas-de-Calais and Picardie in 2014. Thus, forestry of this species could be considered, but would have to take into account all the uncertainties existing about the population dynamics of black locust.
