Abstract

Because of its remarkable geographical position, the Diawling National Park (PND) corresponds to a narrow triangle delimited by the Ocean to the west and the Senegal River to the east in the extreme south-west of Mauritania. During the 1990s, after the creation of the Diama salt barrier, it has also promoted an unexpected development of invasive plants such as Typha. To monitors and quantifies changes in the use of the land in the NDP by this plant. We used remote sensing, and we resorted to the use of satellite images taken on separate dates and included the analysis of Landsat scenes (TM, ETM + OLI and TIRS). The results highlight the rapid evolution of Typha acreage during the last three decades, with the most marked changes in the Gambar basin now covered 70% by this plant. Cattail has strongly changed the climax of the area.
