Irů dvůr

Irů dvůr is a small but ecologically notable nature monument on the eastern edge of Prachatice, in the South Bohemian Region of the Czech Republic. It's a stop for travelers exploring the Šumava Foothills who want to pause among quiet meadows and learn how a modest patch of land has been protected and re-protected over three decades.

Where exactly is Irů dvůr located?

The site lies within the Prachatická hornatina, part of the wider Šumava Foothills, right at the eastern edge of the town of Prachatice. The terrain sits at an elevation of 570 to 680 meters above sea level, giving it a gently rolling character typical of the surrounding countryside. The entire protected area covers just 2.81 hectares, making it one of the smaller designated nature sites in the region — yet its protection history is unusually layered for such a compact plot.

Why was this site protected in the first place?

The protection of Irů dvůr dates back to April 15, 1992, when the Prachatice District Office declared it a nature monument. The original justification was the presence of two rare meadow plant species: the broad-leaved marsh orchid (Dactylorhiza majalis) and the Siberian iris (Iris sibirica). For years, the site served as a refuge specifically for these two plants.

Over time, however, both originally protected species disappeared from the location entirely. In response, the South Bohemian Regional Office re-declared the nature monument on October 26, 2023, this time with a redefined conservation purpose. Today, the focus is on maintaining habitat conditions favorable to protected meadow butterflies and other specially protected plant and animal species associated with this type of grassland.

What butterfly species can be found here?

The meadows of Irů dvůr provide habitat for several distinctive butterfly species, including the scarce fritillary, the swallowtail, and the marbled white. Their continued presence depends heavily on consistent meadow management — without regular mowing, the habitat would quickly lose its value for these insects, which is precisely why the site's protection status was updated rather than lifted after the original plant species vanished.

Is there a trail for visitors to follow?

Yes. Already in 1992, alongside the site's initial designation, an educational nature trail measuring 750 meters was laid out through the area. The route originally featured ten themed stops, guiding visitors through the most notable parts of the terrain and explaining the ecological value of the meadows. The South Bohemian Regional Office continues to manage the site, overseeing both the trail's upkeep and the ongoing mowing regime needed to preserve the habitat.

What's the story behind the site's history?

For decades, the symbol of Irů dvůr was an old linden tree, known locally as the Irů lípa, which stood within the protected area and served as a local landmark. The tree died in 1984, but an information board still marks the spot where it once stood — a small but telling reminder of just how long this modest piece of landscape has held meaning for the people of Prachatice.
