Dobročkovské hadce, Natural monument near Dobročkov, Czech Republic.

Dobročkovské hadce is a protected area stretching along a stream with exposed rock formations and marshy meadows in rolling country. The site sits at around 650 meters elevation and includes various habitat types that together create a complex ecological mix.

The area was farmed for years, mown or grazed by cattle and fertilised with manure, before protection was declared on 3 March 1992 by the Prachatice district office. The declaration understated the area by about one hectare because some parcels were imprecisely surveyed. Management resumed in 1996, and on 1 October 2015 the northern part was re-declared and enlarged, changing its status from reserve to natural monument.

Researchers value this location for studying rare plant species and distinctive soil types found nowhere else nearby. The site holds significance for understanding Czech ecology and attracts scientists interested in unusual habitats.

The area has marked trails for nature walks, but visitors should stay on paths and respect the natural surroundings. Weather conditions can change quickly, so wear sturdy footwear and bring appropriate clothing.

The serpentinite bedrock is rich in nickel, chromium and cobalt, which are toxic to most plants; only specially adapted species thrive on these dry northern slopes. A 1995 survey recorded over 300 plant species here, including the critically endangered Gentianella bohemica.
