Kozí vršek

Kozí vršek is a small but ecologically remarkable nature monument sitting on the northeastern edge of the village of Vlkov, in the Tábor District of South Bohemia, Czech Republic. Covering just 0.38 hectares, it ranks among the tiniest protected areas in the region, yet it has drawn the attention of botanists and nature lovers across the country for nearly a century.

Why is this small hill protected?

Protection of Kozí vršek was established on April 30, 1924, making it one of the oldest protected sites in the Třeboňsko area. It holds the status of a nature monument and is classified under IUCN Category IV, meaning it is managed specifically as a habitat area for a particular species. The main reason for its protection is the presence of the spring pasque flower (Pulsatilla vernalis), a rare and strictly protected plant whose local population has collapsed dramatically over the decades. Where thousands of specimens once grew here, only a handful of individual plants remain today, with typically just one or two flowering in any given year.

What is there to see?

Kozí vršek is a modest hillock built on gneiss, a metamorphic rock typical of this part of the Czech Republic. Its rocky outcrops give rise to shallow, nutrient-poor soil that supports a distinctive, dry-loving (xerothermic) plant community. The site sits at an elevation of roughly 417 to 422 meters above sea level.

Two-thirds of the monument's area is covered by oak-pine woodland, with birch appearing here and there. The ground layer is dominated by grasses and plants adapted to poor, dry conditions, including sheep fescue, wavy hairgrass, and heather. It is precisely this combination of exposed rock, thin soil, and open, sun-drenched vegetation that has allowed the spring pasque flower — a species that needs plenty of light and little competition — to survive at all.

A history of grazing

Before it was placed under protection, the land at Kozí vršek served as pastureland for livestock. Regular grazing kept the hillside open, preventing shrubs and trees from taking over and creating exactly the sunny, low-competition conditions the pasque flower depends on. Once grazing stopped and formal protection began, trees and shrubs gradually started reclaiming the slope — a process that has since become the single greatest threat to the site's rare flora.

How is the site managed today?

Conservation work today focuses mainly on removing self-seeded trees and shrubs that would otherwise shade out the ground vegetation. Without this ongoing intervention, sun-loving, xerothermic species — the spring pasque flower above all — would stand little chance against faster-growing woody plants. The goal of these management efforts is to recreate conditions similar to the site's former life as an open, grazed hillside.
