State of riparian vegetation of streams in the watershed of the Inaouène wadi (NW Morocco). Integrated management of water resources interfere, directly or indirectly, with the conservation of biodiversity. Surveys conducted along the Inaouène wadi (upstream of the catchment of the Sebou River) allowed us to identify 308 taxa of higher plants, belonging to 181 genera and 55 botanical families. The specific richness per station can exceed 100 species depending on the width of the stream bed and conservation. A correspondence analysis is done from 27 botanical statements, described 75 species, and highlighted four plant communities, especially along the "upstream-downstream of the dam” gradient. The main environmental and anthropogenic factors influencing the habitat quality of the river Inaouène were underlined. These factors are responsible for the “upstream-downstream” and transversal zonation of the river vegetation, and the high rate of therophytes.
