Oil palm monoculture is the most rapidly increasing large‐scale crop in Amazonia due to favourable environmental conditions and incentives from executives and governing authorities. In this study we assessed the effects of oil palm plantations on Odonata assemblages in Amazonia streams. We hypothesized that (1) the expansion of oil palm plantations over the natural landscape affects the habitat structure and physicochemical properties of streams at different scales (50 m, 500 m and 1000 m) and (2) oil palm plantations affect the species composition of Odonata assemblages, leading to the replacement of forest specialist species by non‐forest specialists. A total of 22 streams were sampled which were distributed throughout a landscape comprising areas of oil palm plantations Elaeis guineensis Jacq. to streams located inside large forest remnants. The expansion of oil palm monoculture affected the physicochemical properties of the water and habitat of the streams. A larger amount of woody debris was observed within streams surrounded by a greater amount of forest, whereas streams with a greater area of surrounding oil palm had higher pH values and anthropogenic infrastructures (e.g. roads). As expected, the Odonata community was affected by a replacement of forest specialist species with non‐forest specialist species. To mitigate this impact, we suggest increasing the area of native riparian corridors along streams that flow through oil palm plantations.
