Rokytská slať, Fen in Modrava, Czech Republic

Rokytská slať is a raised bog containing numerous small ponds and pools scattered across a complex wetland ecosystem. The landscape is dominated by low vegetation and characteristic plant species adapted to the wet and acidic conditions of the peatland.

The bog was once accessible by a walking trail that led to Mount Roklan until the mid-20th century. The installation of the Iron Curtain after World War II cut off public access and transformed the area into a restricted zone.

The name Rokytská slať probably derives from the moss rokyt, and the bog is also called Rokytecká or, in German, Weitfäller Filz. The Rokytka stream drains it over 4.4 km through the naturally treeless Rokytský valley before joining the Roklanský potok.

Access to the wetland is not permitted as it lies within the strictest protection zone of Šumava National Park. Visitors can only observe the area from a distance or from allowed viewpoints in the surrounding region.

The bog holds 69 pools, the highest count among the Šumava peat bogs, and its Mrtvý les of dead trunks is matched by dwarf and frost-shaped spruces, pines and birches. The whole area is closed to the public, but the bog can be seen from Roklan, 4.5 km away.
