Bosonožský hájek, Nature reserve in Brno-Bosonohy, Czech Republic.

Bosonožský hájek is a forested nature reserve on loess with deep erosion gullies, on the western edge of Brno-Bosonohy. Sessile oak dominates the canopy, mixed with Scots pine and small-leaved lime; hornbeam, field maple and beech increase in the shaded ravines. The herb layer held 284 higher plant species in 2008, 41 of them endangered.

The loess slopes at Zadní boří were farmed until erosion cut deep gullies, making the land agriculturally uninteresting and allowing it to be reforested. The forest that grew back is now protected as a nature reserve and is part of the Natura 2000 network.

The reserve's name refers to the barefooted people of Bosonohy, the Brno district at whose western edge it lies. Its old coppiced stumps and hollow trees shelter the stag beetle (Lucanus cervus) and the tanner beetle (Prionus coriarius), while the meadows on the southern edge hold the praying mantis (Mantis religiosa).

The reserve lies on the western edge of Brno-Bosonohy in the Zadní boří locality, within the Natura 2000 network. The loess subsoil holds deep gullies formed by past erosion, so the ground is uneven and steep in places. The southern edge has meadows where the praying mantis has been recorded.

The reserve has 347 recorded macrofungi species, among them the protected Fechtner's bolete (Butyriboletus fechtnerii), the umbrella polypore (Polyporus umbellatus), the ochre saddle (Helvella pithyophila) and the lilac webcap (Cortinarius sodagnitus).
