| http://www.w3.org/ns/prov#value | - In Europe, this species has suffered mainly from the loss and degradation of steppes and dry grasslands through agricultural intensification, plantation establishment and declines in sheep pastoralism, causing a decline in key prey species; offtake for falconry is a serious problem, which has caused local extinctions (Baumgart 1991, 1994, K. Ruskov in litt. 2007).
