"The map collection falls under results of multiyear research focused on species distribution. There were 7,000 Black Grouse males shot in the Czech Republic in 1933. In 1950, the species was still common in most of the territory, but in 1977 it was recorded at only 15 % of its original range. A steep decline has further continued and currently the species is found only at mountain clearcuts caused by air pollution and in military training areas disturbed by heavy machinery. Its population was estimated at 2,500-4,500 males in 1973-1977 (with quadrate occupancy of 22 %), at 1,100-2,200 males in 1985-1989 (15 % quadrates) and at 800-1,000 males in 2001-2003 (10 % quadrates). The species is classified as endangered on the Red List of the Czech Republic."@en . "RIV/60460709:41330/12:58241" . "42300-sim-0302" . "Bej\u010Dek, Vladim\u00EDr" .
