Obřanská stráň

Obřanská stráň is a small but botanically remarkable nature reserve within the city of Brno, in the district of Obřany. Covering just 1.22 hectares, the site was granted protected status in 1987 because of its rare steppe-like plant communities growing on a rocky, south-facing slope.

Where exactly is Obřanská stráň located?

The reserve lies in the Adamov Highlands, on the right-hand slope of the Svitava River valley, at a point where the river forms a pronounced meander within a narrow breakthrough valley. The rocky slope rises directly above the first railway tunnel on the line heading toward Adamov, which makes the site easy to spot for anyone walking or cycling along the Svitava valley.

Why was this site placed under protection?

The reserve was established to protect rocky slopes covered with steppe meadows, home to thermophilic plant species that have become rare in this part of Moravia. Among them are the greater pasque flower, tuberous pea, dwarf cherry, wall germander, hoary cinquefoil, and cushion spurge. It is the presence of these species, adapted to dry, sun-exposed, rocky habitats, that justified the site's legal protection.

What is the reserve's greatest botanical rarity?

The most valuable botanical feature of Obřanská stráň is considered to be its population of feather grasses — steppe grass species that, despite the reserve's tiny size, form a surprisingly rich community here. Finding several feather grass species growing together in one location is unusual in Moravia and stands as one of the main reasons this modest reserve carries such high natural value.

What animals can be found here?

The warm, rocky slopes also favor insects and reptiles typical of steppe habitats. Among the species most commonly observed are grasshoppers, including forms with a bluish tint to their wings, along with the sand lizard, which readily basks on sun-warmed stones.

Is Obřanská stráň worth a visit?

Given its small size, the reserve is not a destination for a lengthy excursion, but it works well as a stop along a longer walk or bike ride through the Svitava valley. The steep, rocky terrain calls for caution, and straying from marked paths can damage the protected vegetation — visitors are encouraged to stay on the trails and observe the flora and fauna without venturing onto the steep, stony sections of the slope.
