This document describes the unique Polish desert landscape of the Sowiski National Park. It notes that the park protects moving barchan and parabolic dunes that are covering former wet areas. While past attempts to plant pines to stabilize the dunes failed, forests are now growing naturally in low-lying areas. Wandering dunes occasionally bury trees, leaving only dead trunks visible. The dynamic dune area is located between the sea and Lake ebsko.
