This work has been realized in order to bring a meaningful contribution to the acquaintance of all the events and procedures carried out to the final completion of the Reclaiming Plan about the Molentargius area during the years besides the study of the Molentargius’ flora, which have contributed to the Park’s birth. The punctual analysis of every action realized allows to better understand the effects that such processes has created in the floristic and vegetable ecosystem. In particular the bibliographical and herbarium researches have been deepened to obtain a complete panorama of the pre-existent activities about the vegetable elements of the Molentargius area. On field analyses, through relief carried out directly in field, have allowed to characterize the flora currently present in the Park made up of 498 “taxonomic units” (368 species, 128 subspecies, 2 different varieties, distributed in 69 families and 276 genera. Such data have supplied the base for different elaborations and comparison among vegetable species. The analysis of the biological spectrum puts in relief the character of strong Mediterranean component of the Molentargius area, thanks to the high presence of the Therophytes that approximately constitute 57% of the vegetable patrimony; the Mediterranean component of the flora appears also evident from the analysis of the chorological categories in which the Mediterranean elements, also comprehensive of the endemic species, represent about 68% of the vegetable species examined.
