Population justification: The European population is estimated at 1,290,000-2,120,000 calling or lekking males, which equates to 2,590,000-4,240,000 mature individuals (including 1-1.5 million pairs in European Russia) (BirdLife International 2015). This is marginally higher than the last European population estimate of 1.3-2 million breeding pairs (BirdLife International 2004) and higher than the 1.1-1.8 million pairs previously estimated by Schäffer and Mammen (1999). A further 515,000-1,240,000 pairs are estimated for Asiatic Russia, yielding a global total of 3,600,000-6,700,000 mature individuals. Given the high level of uncertainty in some of the breeding estimates and the apparent scarcity of the species in its non-breeding areas in sub-Saharan Africa, the total population may fall at the lower end of this range; even in the low millions.
Trend justification: Ongoing monitoring since 2002 in Russia (which holds the vast majority of the global population) indicates that numbers have remained stable or are even increasing, with some fluctuations due to extreme weather (A. Mischenko in litt. 2010). Whilst it is difficult to accurately predict future trends owing to the species's extensive range and differing climatic and agricultural conditions in different regions, it is thought that populations in key parts of the range in Russia and Kazakhstan are unlikely to change dramatically in the near future. Its conservation status remains unfavourable in some parts of its range with declines reported in several range countries (BirdLife International Corncrake Conservation Team 2015) although the overall European population trend was recently estimated as stable (BirdLife International 2015). Land-use changes are precautionarily predicted to drive a future decline of 1-19% in the forthcoming three generation (11 year) period.
