Abstract
Abstract Some aspects of the nesting ecology of the European pond turtle (Emys orbicularis) were investigated in the summer of 1997 and for one week in the summer of 1998 in South Lithuania. In the study area 3 nesting areas lie 150–1000 m distant from the main pond where turtles live. All nesting areas are in front of a pinewood and have a southeast or south-west exposition. Nests were known if they were observed directly or from the evidence of digging. Females nested in open areas on sandy ground 1–5 m away from the nearest tree. The mean clutch size averaged 12.5 eggs and the mean depth of the nests averaged 12.3 cm in 1997.
