Diversity, natural habitats, ethnobotany and conservation of the flora of the Macta marches (North-West Algeria)

A floristic, ethnobotanical and natural habitat study was carried out in the wetlands of the Macta marshes in northwest Algeria. The specimens obtained made it possible to identify 89 taxa of plants belonging to 32 botanical families dominated by the Amaranthaceae and Asteraceae. Analysis of the chorology of the plants has shown dominance of the Mediterranean element, but only 3 endemic taxa are recognized. Five of the taxa are considered rare and 4 are protected in Algeria; 5 have an IUCN status of minor consideration and Spergularia doumerguei P. Monnier has the status of vulnerable. Analysis of local plant communities has shown the existence of 6 plant groups within 3 types of natural habitats that have been mapped. The ethnobotanical study carried out on 100 inhabitants of the study area made it possible to recognize 73 useful plants of which 69 are used for medicinal purposes.
