Distribution of two invasive alien species of union concern in Cyprus inland waters.
Spatial baseline distribution information on the presence of the freshwater invasive alien species pond slider Trachemys scripta and the red swamp crayfish Procambarus clarkii, in Cyprus, is comprehensively reported for the first time. These species have established populations in 44 inland lentic and lotic water bodies, both natural and man-made. The species occur in syntopy in eight locations. Trachemys scripta is found in 15 locations, of which only 3 locations do not have established populations.Procambarus clarkii is being reported in 30 sites with established populations. This information is a stepping-stone for promoting management measures, for the successful control and/or local eradication of these species in Cyprus.
