The introduction of the aquatic carnivorous plantAldrovanda vesiculosa to new potential sites in the Czech Republic: A five-year investigation

Five microsites in shallow dystrophic waters were selected for the introduction of a critically endangered aquatic carnivorous plantAldrovanda vesiculosa in the Třeboň region in S Bohemia, the Czech Republic. The selected sites were fen pools close to two hypertrophic fishponds, Ptačí blato (four microsites) and Domanínský (one microsite). In June 1995, 30 plants from an allochthonous population in E Poland were introduced in each of the microsites. Water chemistry and plant growth dynamics were investigated at the microsites throughout the 1995–1996 seasons, and the maximum size of the subpopulations were estimated during the 1997–1999 seasons. The selected waters may be characterized as oligo-mesotrophic.
