Abstract Para grass (Urochloa mutica) is becoming an increasingly common weed across Australia's tropical rivers and floodplains. There are concerns about its effects on biodiversity, but there have been few attempts to quantify these. This study (Northern Territory, Australia) compared the terrestrial invertebrates found in para grass, 2 species of native grass, i.e. hymenachne (Hymenachne acutigluma) and wild rice (Oryza meridionalis), and areas where para grass was removed with herbicide. Samples were collected in the dry season and the wet season. In both seasons, para grass had lower richness and abundance of terrestrial invertebrates than hymenachne. There were no noticeable differences between para grass and wild rice. The differences were probably due to the lower plant moisture and nutritional quality of para grass and could have effects on other floodplain fauna.
