Europe: SPEC category 3, declining
UK: Red (>50% population decline)

Long-term trend
UK, England: rapid decline
 
Status summary
The CBC/BBS trend is of severe declines in Turtle Dove abundance, beginning in the late 1970s and continuing to the present. Analysis of nest record cards and ringing data for farmland Turtle Doves suggests, although without statistical significance, that productivity has increased while annual survival has fallen (Siriwardena et al. 2000, 2000b). Hunting during migration is a possible cause of the decline, to add to those related to agricultural intensification that have been postulated for other farmland seed-eaters (O'Connor & Shrubb 1986, Krebs et al. 1999).
