Invasive apple snails (Pomacea spp.) may negatively impact aquatic species in Cambodia. Using citizen science via the free software iNaturalist, we will quantify the co-occurrence of apple snails with native frogs and toads which are commercially important food species and include endangered species. Analysis of resulting records combined with existing data on e.g. land use, will provide information critical for protecting these species and to raise the profile of invasives research in Cambodia
