Xaverovský háj, Natural monument in Dolní Počernice, Czech Republic.

Xaverovský háj is a protected forest area in Dolní Počernice featuring winter oak, white birch, and linden trees spread across roughly 70 hectares. The site contains varied forest types that create natural diversity in plant communities.

The forest belonged to the Dolní Počernice estate of the Čejka family of Olbramovice, covering 55 hectares reforested after villages were destroyed in the Thirty Years' War. It later passed to the Colloredo, Swerts, Ehrenfeld, Dohalský, Enis and Dercsenyi families. In the 1960s surrounding land was added and the western half planted; since 2002 the City of Prague has owned the whole area.

The protected forest demonstrates native oak woodlands and allows visitors to encounter natural forest communities up close. Local residents value the area for walks and observing forest wildlife.

Marked hiking trails connect the area to the nearby Klánovice forest and offer different routes for exploration. Benches near Eliška pond allow you to rest during your visit.

In the 1960s the surrounding land was added and the western half of the grove was planted, so the forest is not one age: the eastern part grew after villages destroyed in the Thirty Years' War, the western part only in the 20th century. Entomologist Dr. Pulpán found large ground beetles here.
