The global population is estimated to number c.790,000-3,700,000 individuals (Wetlands International 2015). The European population is estimated at 223,000-391,000 pairs, which equates to 447,000-782,000 mature individuals (BirdLife International 2015). National population estimates include: c.100,000-1 million breeding pairs and >c.10,000 individuals on migration in China; c.100-10,000 breeding pairs and c.1,000-10,000 wintering individuals in Korea; c.100,000-1 million breeding pairs and >c.10,000 wintering individuals in Japan and c.100,000-1 million breeding pairs and >c.10,000 individuals on migration in Russia (Brazil 2009).

In Europe the species was heavily persecuted in the nineteenth century due to its consumption of fish, which resulted in competition with fishermen and fish farmers (Kushlan and Hancock 2005). Although killing at aquaculture farms has not reduced the global population so far (possibly because it is young birds that are mostly killed) (Kushlan and Hancock 2005), 800 herons are estimated to have died per year at Scottish fish-farms between 1984 and 1987 (Carss 1994, Kushlan and Hancock 2005) by being shot, drowned or poisoned by fish farmers (Carss 1994). Renewed hunting poses a threat to Bavarian populations by decreasing ... Read More
