Natural monument Niva Olše-Věřňovice, Natural monument in Dolní Lutyně, Czech Republic

Natural monument Niva Olše-Věřňovice is a protected area featuring three linear tree stands that developed on the remnants of old fish pond dikes. These wooded strips form distinct landscape features that visitors can observe as they walk through the site.

The protected area was established on 3 December 2013, and its three narrow strips are former fish-pond dikes that kept their old oak stands. The site lies by the Olše river near the Czech-Polish border and is part of the Natura 2000 network.

The name Olše refers to the Olza river, which forms the nearby Czech-Polish border; Věřňovice is the village the site adjoins. The three protected strips lie east and west of Věřňovice, and a separate natural monument, Věřňovice, stands north of the village.

The monument lies in Dolní Lutyně's cadastre near Věřňovice and the Olše river, close to the Czech-Polish border. It consists of three separate narrow strips, two east of Věřňovice and one west of it, so plan a route linking them. The strips are former pond dikes lined with old oaks; paths are unmarked, so wear sturdy footwear.

The beetle the site protects is Osmoderma barnabita, the brown chafer, not a stag beetle. Its larvae develop in hollows of old oaks on the former pond dikes, which is why the three narrow strips were declared a monument on 3 December 2013.
