between 2000 and 2010).Cyprinuscarpiois perceived as stable for some interviewed and
declining for others (Cabras, Santa Giusta and S'EnaArrubia). Eichhornia crassipes
seems to have bloomed in Cabras between 2010 and 2011 and then disappeared, as for
Santa Giusta between 2016 and 2018.

C. sapidus is currently widespread in all the lagoons with more than 5 records per each
basin (Fig. 2), except for Is Benas where only occasional specimens until 2021 have
been reported. Moreover, a focus on 3 of the most abundant reported NIS is performed
in Cabras(Fig. 3), where the highest number of interviews was collected (N=11).
