Zeman, Natural monument near Starcova Lhota, Czech Republic.

Zeman is a small, shallow fishpond nature monument near Křenovy Dvory by Nadějkov in the Tábor district, in the Vlašim Hills at 636–638 m. The pond covers 0.74 ha, averages 0.6 m deep and reaches 1.5 m, with banks and a protective zone in the middle of pasture land.

Zeman was declared a natural monument on 8 November 1993 by the Tábor district authority. The pond itself is documented from 1836 and was built for fish farming, a use it still serves under conservation rules. Its species mix depends on rainfall and pond management: in 2005–2009 river horsetail spread massively, while in 2012 the nearly water-filled basin limited rare plants.

The pond has been used for fish farming since at least 1836, and this use continues today, provided that interventions remain compatible with the protection of local species. Its water level and the extent of its reed and horsetail beds depend on rainfall and on how the pond is managed.

The pond lies at 636–638 m in the Vlašimská pahorkatina, 1 km west of Starcova Lhota and 4 km southeast of Nadějkov, within the Jistebnická vrchovina park. It has no inflow and depends on rainfall, so water levels and the extent of reed and horsetail growth vary from year to year. The protected area covers the pond and its banks, surrounded by pastures.

The critically endangered Calamagrostis purpurea subsp. phragmitoides covers only about 50 m² here, and the Siberian iris grows in a single clump. Because the pond has no inflow, these stands depend entirely on rainfall and on the fishpond management cycle.
