%X Worldwide, exotic species play a important role to biodiversity, once numerous species are spreading uncontrollably and dominating different ecosystems, interfering in the balance of these areas, and even modifying the natural features of the landscape. Despite of all the studies, the distribution of Annoni Grass in large and continuous mapping units, as well as its quantification and the spatial advance that it has been presenting through the territory of Rio Grande do Sul are still unknown. Normally, to identify vegetation species in large mapping units, indirect estimates such as remote sensing techniques are used. However, identifying species requires not only indirect estimates, but also an analysis of the field data collected about the observed species that allows us to characterize them spectrally. Thus, to differentiate the spectral response of Annoni Grass, it was performed a spectroradiometry measurement of different species of grasses predominant in the Ibirapuitã Planning and Management Unit (UPG) of the Ibicuí River watershed, in the Southwest region of the State. The spectral response of the intermediate part of the leaves of the grasses was collected in loco under real conditions of the environment. After the statistical analysis, it was verified that in the visible and near infrared, i.e.,wavelength from 500nm to 900nm, the possibilities of spectral separability of the Annoni Grass are higher in relation to the other species. Within this context, we conclude that along the wavelength there are significant differences in the spectral response of the Annoni Grass when compared with the analyzed species.
