For a long time Corn crake (Crex crex) was labeled as endangered species, so it is useful to observe its population size and occupied localities. In 2005–2009, occurrences of Corn crake were mapped in Kraslice district and occasional observations were performed in Karlovy Vary region. In most localities, Corn crakes nested only once that year, some localities served as a regular breeding place. The situation between years was stable. In the text, we advise some management which could lead to preservation or increase in the Corn crake population. The most effective way is a shift of first grass-cutting day to August.
