Utilisation de la télédétection pour la connaissance et la gestion d'une plante invasive : cas de la Jussie sur le bassin de la Vilaine

Abstract : Remote sensing - the acquisition and the processing of satellite or airborne images - is more and more used by scientists and environment managers to see how the vegetation lies (presence, absence, plant cover, etc.). Indeed, various possibilities are offered: vegetation mapping, change detection within the plant communities from one year to the next, calculation of biophysics variables, etc. In particular, remote sensing is used to follow invasive plants and helps towards their management. The consequences generated by the proliferation of these invasive species are numerous. It is essential to be able to locate them precisely in order to follow their evolution and take the necessary actions. The advantage of remote sensing is to obtain information quickly on big surfaces, with little ground knowledge. This report presents a study realized within the research program led by the Institution d'Aménagement de la Vilaine (IAV) and Agrocampus Ouest about the Jussie (two Ludwigia taxon). It is an amphibian invasive plant which proliferates on the la Vilaine river catchment area in Brittany. First, a wide scale study is detailed. Using SPOT5 images, it allows the diagnosis of the river system and the implementation of a surveillance program concerning the amphibian vegetation development. Secondly, a fine scale study is presented. It explains the various possibilities from HySpex images for the improvement of the Jussie knowledge and management on the catchment area.
