TERRESTRIAL MOVEMENTS OF THE SOUTHWESTERN POND TURTLE

The terrestrial habitat of the semi-aquatic southwestern pond turtle (Actinemys pallida) remains under-researched compared to its aquatic environment. This study documents the nesting and estivation movements of A. pallida in southern California from 2009 to 2024, along with a potential hatchling migration. Utilizing radio telemetry on transmittered turtles and observations of naturally encountered individuals, we measured distances from aquatic habitats to terrestrial movement locations. These behaviors are critical for population survival and provide essential insights for the conservation and management of A. pallida. Understanding the terrestrial movements and habitat preferences of this cryptic species is vital for effective conservation strategies.
