Understanding how ecological factors influence plant communities is essential for biodiversity conservation, especially in regions experiencing climatic and anthropogenic pressures. In this context, the present study explores the floristic diversity of four wetland sites in Taza province (Morocco): Oued M’Soun, Ras-El-Ma, Oued Elbared, and Lac Tameda. These sites, representative of the region's ecological variability, offer a valuable opportunity to assess the relationship between environmental conditions and plant distribution. Floristic surveys were conducted in March 2024 using 10 m² plots, complemented by physico-chemical soil analyses (granulometry and pH), satellite-derived vegetation indices, notably the Normalized Difference Vegetation Index (NDVI), and statistical analyses including Principal Component Analysis (PCA) and hierarchical classification. The NDVI was employed to assess vegetation vigor and spatial distribution patterns at each station, providing a quantitative complement to field observations. The results reveal significant differences among the stations in terms of precipitation, temperature, soil type, pH, and NDVI values, all of which shape the composition and health of local vegetation. A high level of plant diversity was observed, with dominant families including Asteraceae, Lamiaceae, and Rosaceae. Some species, such as Scolymus hispanicus and Carduus pycnocephalus, were present at all four sites, highlighting their ecological adaptability, whereas others, like Juniperus thurifera and Nerium oleander, were restricted to specific habitats. The PCA and classification analyses distinguished three floristically distinct groups of stations, structured according to environmental gradients, including vegetation vigor inferred from NDVI. These findings underscore the uniqueness of Taza’s flora within semi-arid Mediterranean ecosystems and emphasize the need for conservation strategies adapted to the pressures threatening these natural habitats.
