Inventory Of The Urban Flora Of The City Of Kénitra (Morocco)

Abstract

The city of Kenitra is located on the south shore of Oued Sebou in a sub-humid bioclimatic atmosphere with a moderate winter. The soil is generally sandy clay on the side of the Mamora and sandy on sandstone substrate to the west, when it is not concrete. It is a city polluted by the many factories that it hosts. The census of urban vascular flora could be used to propose a land management strategy adapted to the context of the city of Kenitra. For this,the urban area was sampled systematically by following the alleys, streets and boulevards throughout the city. The samples collected were identified in the laboratory.The results of this identification made it possible to establish a list of 178 species affiliated to 152 genera and 64 families. The richest family in species is the Asteraceae (27 species), followed by that of the Fabaceae (13 species), the Poaceae (12 species), and the Lamiaceae (8 species). Therophytes are the most represented (77 species), followed by hemicryptophytes with 29 species, phanerophytes (24 species), Chamaephytes (19 species), nanophanerophytes (16 species), geophytes (10 species), and mesophanerophytes (3 species). It is rich and diverse vegetation that effectively contributes to the decontamination of the city by recycling the carbon dioxide released into the atmosphere and reducing the effect of heat islands created by increasing urban planning.
