Černá jezírka, Nature reserve near Bílý Potok, Czech Republic

Černá jezírka is a nature reserve on the Central Jizera Ridge, a peat bog complex at 885–912 m between the Baltic and North Sea watersheds. It covers 66.6 ha with a 72.4 ha buffer, and its waterlogged spruce stands are mostly in decay, with peat up to 4 m deep.

The reserve was established in 1960 and suffered severe forest damage during the 1980s from air pollution and acid rain. Recovery of the woodland has started gradually since then.

The painter Wenzel Franz Jäger was drawn to this area and captured it in his work. The name Černá jezírka refers to the dark bog pools, and the reserve lies within the first zone of the Jizera Mountains Protected Landscape Area, where movement is restricted.

Most of the reserve is nearly impassable because of the wet, broken terrain; a boardwalk crosses only a small part of it. The reserve lies in the first zone of the Jizera Mountains Protected Landscape Area, so movement is restricted. It sits near Rybí loučky and the Jizerka settlement, under the municipality of Kořenov.

The site contains peat deposits reaching depths of 4 meters that support rare plant species. These boggy areas provide scientists with valuable information about ecological processes and regional biodiversity.
