The present scientific approach proposes a preliminary study on habitat suitability and factors’ influence using the herpetological indicator Vipera ursinii moldavica and is intended to depict well adapted preservation measures for the Ponto-Sarmatic ecosystems in the context of increased human pressure. The primary goal is to establish an impact hierarchy for the controlling factors. The study incorporates various natural and human related factors via correspondence analysis in order to mark out for the most influential ones. The goal is to enhance understanding of variables’ contribution to the process and find appropriate intervention measures as far as the Natura 2000 Management Plans are concerned.
