To the north of the Sudety Mountains, in south-western Poland, extends a vast area of sandurs overgrown with forests called Bory Dolnośląskie which can be translated as Lower Silesian Forests. Because of the little fertile soils those forets survive, while most of other, more fertile areas of Lower Silesia, were converted into cropland. After II World War, when Soviet Union began to occupy “liberated” countries, they installed numerous troops of the Red Army in this area.
There were many military training gounds in the midst of these forests. After the exit of soviet troops from Poland, when training grounds were abandoned, regeneration of the forest undergrowth took place. Heathlands came to revive.
