Abstract
A comprehensive study was conducted in the Sečovlje Salina Nature Park, one of the largest coastal brackish areas in Slovenia, to investigate the habitat requirements of the European Pond Turtle (Emys orbicularis). During 2019-2020, five female turtles were monitored using GPS solar-powered telemetry transmitters. Based on the high-resolution LiDAR data and spatial analysis, the study aimed to compare the activities of individual turtles on a monthly and hibernation basis across two ecologically distinct but neighbouring areas within the park. The data collected over such a short (monthly) period provides valuable insights into habitat requirements, seasonal spatial dynamics, and the contrasting environmental conditions. The findings contribute essential baseline information for understanding and developing future conservation strategies for this endangered species in coastal brackish wetlands, which tend to be locally specific and vulnerable to numerous human-induced pressures.
