Wolf populations in Poland have increased to about 800–900 individuals since being classified as a game species in 1976, now for more than two decades under legal protection in Annex V and II of the FFH Directive. The number of wolf packs in western Poland has continued to increase. This is confirmed by the results of the wolf monitoring financed by the International Fund for Animal Welfare (IFAW) and the nature conservation foundation EuroNatur, which is carried out by the Polish nature conservation organisation Association for Nature Wolf (AfN Wolf). The Polish scientists estimated that at the end of the 2018/19 monitoring year, there would be at least 95 resident wolf packs west of the Vistula, more than at any time since data collection began in 2003. For the first time, the scientists were also able to detect at least three reproducing packs in the Sudeten Mountains in the Czech-Polish border area.
