Abstract

Little is known about road mortality and the effects to European pond turtle Emys orbicularis populations at the northern border of its range. Survival of the turtle populations in suboptimal conditions depends heavily on longevity, regular annual breeding and relatively large clutch sizes, but additional unnatural mortality could alter their survival rates. Loss of only single turtle in majority of northern populations could mean a loss of 3-20% of subpopulation. But due to comparative rarity of the road accidents the effects of individual road mortality to the turtle populations might not be recognized. We discuss possible effects of road–associated mortality, and suggest that precautionary measures as setting of the buffer zones with low road density and possibility of lowering of traffic volume must be considered during the planning of the species conservation actions.
