Velký Karasín

Velký Karasín is a protected natural monument centred on a eutrophic pond and its surrounding wet sedge meadows, lying southwest of the village of Vlhlavy in the České Budějovice district of the South Bohemian Region. The site sits on a tributary of the Bezdrevský stream at an elevation of 405–407 metres above sea level, covering an area of 10.78 hectares. Protection was established on 30 December 1991 by the České Budějovice District Office, and the site is classified under IUCN Category IV, meaning its management is focused on maintaining habitat for specific species.

What exactly does the protection cover?

The protected zone focuses on the western part of the pond, where a belt of littoral reed vegetation borders damp sedge meadows. Small, well-preserved ponds with intact natural shorelines like this one have become increasingly scarce across the intensively farmed landscape of South Bohemia, which makes this compact site disproportionately valuable for regional biodiversity.

Which plant species grow here?

Botanists have recorded shining meadow-rue (Thalictrum lucidum) and dwarf viper's-grass (Scorzonera humilis) within the reserve — both species tied to damp, extensively managed meadows, a habitat type that has been steadily shrinking as agriculture intensifies.

Why does the pond matter for birds?

Velký Karasín functions as an important breeding site and migratory stopover for waterfowl and wetland birds. The combination of open water and reed cover provides both shelter and feeding grounds, giving this modest pond outsized importance along regional migration routes through South Bohemia.

What about insect life?

The site is particularly notable for its dragonflies: twenty species have been recorded here, including the winter damselfly (Sympecma fusca), a species considered threatened across Europe. Such species richness points to good water quality and a mix of microhabitats, from open water through reed beds to the surrounding wet meadows.

What else is worth knowing about the surroundings?

The nearest settlement is Vlhlavy, located to the northeast of the pond. The same broader area, within the municipality of Zbudov, includes the village of Plástovice, part of the historic region known as Zbudovská Blata — noted for its preserved folk architecture in the peasant baroque style and its association with writer Karel Klostermann. While Plástovice itself does not sit directly on the pond, it shares the same landscape of wet meadows and fishponds characteristic of the Zbudovská Blata region.
