The survey of flora of the Jezero Nature Reserve (near Dublovice village, Sedlčany region, Central Bohemia) during 2002-2006 is given. 278 taxa of vascular plants were recorded. The high number of recorded species is caused by diversity of vegetation in the reserve.
Aquatic macrophytes and littoral vegetation are the most significant plant communities. Rare plants growing in these communities are endangered because of succession.
