Résumé :	Long-term monitoring of Corncrake numbers and trends was conducted in population strongholds of the species in the Czech Republic, in higher altitudes, since the mid 1990s. Night counts of calling males were performed in the Sumava, the Novohradske Mountains and the Krkonok. Long-term trends were similar in all three study sites. Maximum numbers were recorded in 1998-2003 after an increase in the 1990s. Later on, numbers decreased everywhere, and these changes coincided with changing intensity of agriculture.
