Hadí vrch, Nature reserve in Staré Město pod Landštejnem, Czech Republic

Hadí vrch is a nature reserve on the Výhon summit, which reaches 647 m above sea level, near Staré Město pod Landštejnem in the Rajchéřov cadastral area. Its bedrock is Číměř-type granite of the Moldanubian pluton; near the top sit low frost cliffs with slab-like rock parting, and below them a boulder sea. The soil is strongly acidic typical cambisol.

The slopes were abandoned pastures after World War II and were taken over by natural succession, mainly Scots pine. The site is now a nature reserve, no. 1373, managed by the Agency for Nature Conservation and Landscape Protection of the Czech Republic, which clears self-seeded trees and alder buckthorn from the juniper stands.

The open heathland is a former boulder pasture; grazing ended after World War II, and the slopes then grew over by natural succession, mainly with Scots pine. Conservation today clears self-sown alder buckthorn and other deciduous shoots to keep the junipers free.

Visitors can explore the reserve through public paths that start from the nearby village of Staré Město pod Landštejnem. The area is relatively small and compact, making it suitable for shorter walks.

Hadí vrch is the only known site in the Czech Republic for the moth Oxyptilus ericetorum, recorded on the heathland around the granite boulders below the 647 m summit Výhon. The same slopes also hold the fly Cordyla brevicornis, its only Bohemian locality, and the leaf-miner fly Metopomyza flavonotata.
