The Cuchujaqui River basin has great biological importance housing a significant number of both native and endemic species. It is important, therefore, to detect the presence of exotic species in the place and avoid an alteration in this ecosystem. The objective of this study was to determine the presence of exotic species in the Ramsar Site Arroyo Verde Sierra de Álamos-Río Cuchujaqui Ecosystem by registering its flora. A tour of the nine main sites of the area was carried out, as well as a register of the localized plant species, for a later identification and characterization, and an affinity analysis between the sites and among exotic species. The results obtained reveal the presence of six exotic species in the Ramsar site, which were Arundo donax, Ricinus communis, Cynodon dactylon, Sorghum halepense, Dicanthium annulatum and Melinis repens, which may be causing alterations in the native species of the place.

Keywords : Native species; exotic species; Ramsar site.
