The animals were fitted with radio collars along the border of Germany’s Bavaria region and the western edge of the now Czech Republic during a six-year study.
“Deer on the Czech side of the Bohemian Forest wander no farther than where barbed wire used to mark the restricted area along the national border,” said Pavel Sustr, a Sumava National Park zoologist who headed the study.
Only a small handful of deer were found to break with tradition, wandering a short distance across the border.
It’s believed that female deer pass on territorial boundaries to their young from generation to generation.
Sustr says he thinks that the Iron Curtain mentality will eventually disappear, and more deer will start to wander freely between the two countries.
