The Erika oil spill and the attendant cleaning operations it required have impacted almost every type of Breton shoreline, habitats and plant communities on shingle and sandy beaches, rocky cliffs, marshlands and dunes. The French Ministry of the Environment (Ministère de l'écologie et du développement durable) launched an impact assessment in 2000 on oil spill clean-up operations and the recovery of impacted vegetation via the «Réseau de suivi des conséquences écologiques et écotoxicologiques de la marée noire résultant du naufrage de l'Erika» (Monitoring network of the ecological and ecotoxicological consequences of the Erika oil spill). The Cedre and the Conservatoire Botanique National de Brest are dealing with the terrestrial vegetation program. Vegetation was surveyed in sixty locations where one hundred quadrates were recorded covering all vegetation types including all the degrees of oiling and the varying amounts of damage resulting from the removal of the HFO. A few examples of the oiled areas are discussed. The three year monitoring program shows a high degree of persistence of the HFO in uncleaned quadrates of a number of habitats. The FO 6 did no really serious damage in terms of mortality, vegetation cover and species composition. The survey illustrates how gentle manual oil removal techniques can enhance vegetation recovery within the space of a few years. It also exemplifies how some techniques have a very negative impact such as HWHP washing which only serves to delay recovery.
