Rašeliniště Jizery, Mountain peat bog nature reserve in Jizerské hory, Czech Republic

Rašeliniště Jizery is a peat bog reserve in the Jizerské hory mountains that spans wetlands, marshy meadows, and river areas. The terrain includes subalpine forests and boggy habitats that support uncommon plant and animal life.

The area gained protected status in 1960 to preserve its wetland habitats and uncommon species. This early recognition helped safeguard the natural processes in this highland peat bog system.

Scientists documented 198 beetle species between 1986 and 2004, including diving beetles, ground beetles, and rove beetles within the reserve boundaries.

Visitors should stick to marked paths, as direct access to peat bog areas is not permitted for conservation reasons. The settlement of Jizerka serves as the best starting point for trails into the reserve.

The reserve protects the largest peat bog in the Czech Republic, and an even larger part of the same bog lies across the border in Poland. On the Polish side the protected area was long a small reserve called Torfowisko Izerskie; in 2000 it was greatly enlarged to 484.73 ha as Torfowiska Doliny Izery.
