Population justification: The population is estimated at 11,000-16,000 singing males (M. Flade in litt. 2012), equivalent to 22,000-32,000 mature individuals or 33,000-48,000 individuals in total.
Trend justification: This species probably declined rapidly until the late 1990s, as a result of the destruction of its habitat at a rate equivalent to 40% in ten years. The decline in the central European core population has recently been stopped owing to intensive management and conservation projects but other populations continue to decline through habitat loss and degradation.
